Detailed Description
As shown in figure 1, the comprehensive field level system for the water and electricity engineering construction in the mountain gorge region can effectively solve the problem of the water and electricity engineering construction field construction in the mountain gorge region. The comprehensive field leveling system comprises an upstream cofferdam 1, the comprehensive field leveling system further comprises a slag piling rolling field leveling 2, the slag piling rolling field leveling 2 is located in a downstream side river channel 3 of the upstream cofferdam 1, and construction facilities, temporary factory buildings 4 and temporary office rooms 5 in the engineering construction process are all arranged on the slag piling rolling field leveling 2. The integrated site leveling system is formed by additionally arranging the slag piling rolling site leveling 2 in the river channel 3 at the downstream side of the existing upstream cofferdam 1, and construction facilities, temporary factory buildings 4 and temporary office rooms 5 in the engineering construction process are all arranged on the slag piling rolling site leveling 2. Thus, the problem of construction sites required by the construction of the hydroelectric engineering in the mountain gorge area is solved, and the transportation and preservation problems of various equipment and facilities in the construction process can be solved.
In the above embodiment, in combination with the feature that the hydropower engineering construction needs to construct a retaining dam on the river channel, the integrated site leveling system of the present application further includes a retaining dam construction area 6, and at this time, the slag stacking and rolling site level 2 is located at an upstream side of the retaining dam construction area 6. Correspondingly, in order to facilitate the construction of the upstream cofferdam 1 and the slag piling rolling field level 2, the slag piling rolling field level 2 and the upstream cofferdam 1 are arranged into an integrated structure in combination with production practice.
As described above, in order to shorten the transportation distance of construction waste slag and reduce the transportation cost, so as to facilitate the acquisition of backfill materials for completing subsequent engineering construction, the integrated site leveling system of the application further comprises a slag piling site, wherein the slag piling site is a part of the slag piling and grinding site level 2, which is not provided with a temporary factory building 4, a temporary office 5 and no construction facility.

Meanwhile, in order to enable the engineering of the application to be carried out smoothly, the comprehensive site leveling system also comprises a downstream cofferdam 9, and the downstream cofferdam 9 is arranged on a downstream river channel of the retaining dam construction area 6.
In summary, the construction of the hydroelectric engineering by adopting the comprehensive field leveling system provided by the application has the following advantages,
1. In the high mountain channel Gu Ou, the upstream cofferdam adjacent river channel is used as a temporary slag piling field, not only slag can be piled up, but also a new field formed by piling slag can be used, so that the problem of temporary piling slag in an engineering area is effectively solved, and the requirement of temporary land in the engineering area is relieved; and roads connected with two banks are arranged on the slag stacking field so as to meet the transportation requirement in the construction period field. Meanwhile, the three-in-one combined type highway has the functions of temporarily stacking slag, newly adding temporary land and newly adding and connecting two banks of highways.
2. Before the reservoir stores water, the slag yard is dismantled or slag in the slag yard is transported to a permanent slag yard so as to meet the water storage requirement. According to the total arrangement requirements and the scheduling of construction, the sites are reasonably distributed in different time periods, so that a large amount of outward transportation of slag is avoided, the slag piling problem of an engineering area is solved, and temporary construction sites and in-site transportation lines are increased.
3. The comprehensive field leveling system can effectively achieve the purposes of saving land, occupying no or little land, such as cultivated land, economic forest land and the like, and reducing the number of people moving.
Example 1
The method is located in a mountain canyon area in the west, road arrangement in the field is difficult, transportation cost is high, and temporary slag piling is carried out by utilizing a river channel near an upstream cofferdam in order to solve the problem that an engineering area lacks a field. And (3) moving the upstream cofferdam upwards by 150m according to the total arrangement requirement, leveling a slag yard with the area of 15000m2 between the upstream cofferdam and a dam foundation pit, wherein the average slag height is about 20m, and the slag capacity is 30 ten thousand m & lt 3 & gt. The right bank of the slag yard is a small landslide body, the slope is kept stable in a natural state, but the risk of instability exists after water storage. The slag pile field with the height of 20m before water storage is formed, the slag pile plays a role in fixing feet on a landslide body and plays a positive role in stabilizing the landslide body.
The following three problems are effectively solved at this time:
1) The slag charge stacking problem of earlier-stage construction projects such as diversion tunnel and the like;
2) After the site is leveled by adopting engineering measures, the temporary construction site is added, and various temporary construction facilities can be arranged;
3) The foot fixing treatment is carried out on the landslide body on the right side of the slag yard, which is beneficial to the stabilization of the landslide body.
