Project introduction

In recent 20 years, there have been bank collapses in many sections of Jiangsu section of the Yangtze River, and the water level has repeatedly exceeded the warning water level, setting a new record for the highest water level in history, which seriously threatens the flood control safety, shipping safety and river regime stability in our province. River regulation projects such as bank protection and slope protection are the main ways to maintain stability in the rapidly changing area of the Yangtze River regime. Under the background of the great protection of the Yangtze River and the construction of ecological civilization, how to improve the implementation effect of the bank slope protection project and ensure the construction quality of the project is of great significance for maintaining the stability of the coastline and ensuring the safety of flood control.

Based on the research achievements of the joint application unit of this project in the past 10 years, the construction and scientific research units in the industry have carried out multidisciplinary joint technical research, aiming at systematically improving the effect of bank slope protection project and studying the key technologies of construction guarantee in Jiangsu section of the Yangtze River from the aspects of river regime influence mechanism, riprap protection type effect evaluation, riprap construction technology innovation, dike stability safety evaluation and ecological slope protection technology, etc., and achieved the following innovative results:

1. Using high-precision multi-beam scanning system and spatial data superposition analysis method, the evaluation of riprap effect is put forward for the first time.bestThe density of point cloud realizes the accurate evaluation of underwater riprap effect; The model is constructed to predict the anti-scour effect of riprap revetment, and the influence mechanism of riprap revetment protection effect is expounded.

2. The research on the influence of sand mining project on the river regime of the bifurcated reach is extended from a single project to the superposition influence of multiple projects; The superposition influence index of multiple sand mining projects on the diversion ratio of braided river is put forward, and the influence law of multiple sand mining projects on the evolution of braided river is proved. This paper reveals the response mechanism of erosion and deposition changes in a single sand pit to other projects, and puts forward a simulation method to accurately predict the riverbed to reach a stable state.

3. The panoramic view of the dike is obtained by using the sounding technology combining ground penetrating radar and multi-beam, and the complete shape of the dike is constructed by registration; The multi-temporal point cloud of dike is used to analyze the deformation of dike, and the feasibility of using point cloud for dike monitoring is clear. Based on fuzzy system and neural network theory, a deformation-based safety evaluation model of dike engineering is constructed. The deformation analysis software of point cloud is developed, and the three-dimensional change analysis of point cloud and the visual view of the results are realized.

4. The failure mechanism and process of geo-reinforced turf are proved, and the influence law of geo-materials and reinforcement technology on impact resistance is obtained; Through numerical simulation and field test, the erosion variation laws of two kinds of geo-reinforced turf at different flow rates are explained. A water erosion test system was designed to reveal the hydraulic erosion resistance characteristics of mixed turf. The in-situ sampling method of three-dimensional geo-reinforced turf was established, and the combined reinforcement effect of geo-mat, plant root system and soil was expounded.

5. A box-type accurate deep-water positioning and throwing construction ship is designed, which integrates positioning, boxing and throwing, and a circulating throwing process of deep-water riprap anti-scour body is developed. The fixed-point accurate throwing construction of the bed is realized by the linkage control of electric winch, hoist, limit device, sprocket and other structures and power systems.

Before the start of this test drive, let me ask you a question: What are the core requirements for 150,000-200,000 pure electric vehicles? My answer is to have a good endurance performance, and it would be better if we could add some bright comfort configuration bonus.

Today’s test drive is the car with the longest cruising range of CLTC within 200,000.

A quick look at the advantages and disadvantages of KIA EV5;

Advantages:

1. 720 (long battery life version) is the pure electric vehicle with the longest CLTC cruising range within 200,000.

2, high comfort configuration, unique design

3, kinetic energy recovery can be adjusted in multiple gears, and can also be set to automatic.

4, square box shape, high originality

5. The backrest of the rear seat has a wide adjustment range, and it can be leveled with the trunk to form a big bed.

Insufficient:

1. Due to the shape of the square box, the wind noise is a bit loud.

2. The interior materials have a strong sense of plastic.

exterior

KIA EV5′ s body line style is hard, which makes me more curious: the official standard has the longest battery life of 200,000, is it really resistant to hitting? This point will be answered for you later.

In addition, the front and rear light groups are skillfully integrated into the body lines, which is more coordinated. It is commendable that the styling of the EV5 is highly original. Although many domestic products are both hard-core styling styles, they will always find the shadows of some other cars, but they will not be on the EV5 at all.

interior decoration

Just now, the price of 150,000-200,000 was mentioned, and users also hope that the vehicle can provide good comfort on the premise of sufficient battery life. Generally speaking, the comfort configuration of KIA EV5 is very high. Today, our test drive configuration is the wave version (the official guide price is 225,800 yuan, except this configuration version, the bare car price of other configuration terminals is within 200,000 yuan), the ventilation and heating of the main and passenger seats are equipped, and the steering wheel heating is not missing.

The central control screen is designed as a triple screen. If you don’t observe it carefully, you may mistake it for a double screen. The air-conditioning settings are independently displayed on a display screen, so that adjusting the air-conditioning during driving will not interfere with the display of other information.

The main driver and the co-driver are connected, and the way to connect is that the co-driver seat is extended to the left, which shortens the distance between them, so I won’t say much about the application scenarios. In short, I will vigorously respond to the family planning policy.

On the disadvantage of the front row, that is, the plastic feeling of the materials is slightly strong, but it is not that kind of stiff plastic, and the surface feels elastic.

The comfort configuration in the back row is very rich, with a refrigerator, a table board and a big bed, which is quite "small ideal".

In addition, the angle of the rear seat adjustment is very wide, making it easy to find a comfortable sitting position. There is a hanger behind the headrest of the front seat, which is suitable for people who need to wear formal clothes every day.

Dynamic performance

In terms of power, KIA EV5 is equipped with the first 160kW single motor by default, and some configurations can be equipped with a four-wheel drive system. There is an extra 70kW motor at the rear axle, which is just the test drive model (CLTC cruising range is 630km after the option).

From the subjective acceleration feeling, the EV5 dual-motor model has abundant power level, but it will not have the violent feeling of domestic dual-motor models within 4 seconds. The throttle adjustment is very delicate, no graininess, and very heel-to-heel.

kinetic energy recovery systemsNeed to mention more, its kinetic energy recovery can be adjusted by using the paddle behind the steering wheel, with a total of five gears adjustable. Setting the strongest gear is equivalent to using the single pedal mode, while the lightest gear can almost match the sliding texture of the fuel car.

From the perspective of chassis adjustment and positioning, it is slightly comfortable and the action is crisp and neat, but it may be because the 19-inch wheel hub is bundled with the four-wheel drive system, and the tire is thinner than the 18-inch wheel hub model, so the feedback of fine vibration is more, but it is not disturbing.

The sound insulation performance is limited by the square box modeling style, and the wind noise is obvious at high speed, and there is still room for improvement, even if the front row adopts double layers.Laminated glass.

Power consumption performance, please look forward to it.

Because the itinerary of this activity is relatively free, Xiaobian decided to squeeze out some time to test the power consumption performance of EV5. As for the result, at present, it can only be revealed that there is no reverse virtual standard, but the calculated endurance achievement rate is excellent. Stay tuned!
