Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mountainous area control floating water, and particularly relates to a control floating water method for a high fill industrial park in a mountainous area. BACKGROUND

[0002] The control of the underground building anti-floating water level in the previous projects is post-control. The underground building anti-floating water level is dewatering of the fixed anti-floating water level which has been determined. The short-term dewatering can reduce the underground water level to the level below the construction foundation. After the completion of the foundation construction or the construction of the structure to a certain height, the dewatering process is stopped to meet the requirement of the operability of the construction process.

[0003] The determined underground anti-floating water level measured according to the survey requirement is generally based on the historical highest water line. When the water level line is high and affects the building anti-floating calculation, it has a great influence on the investment and safety of the buildings in the whole site. For the high fill foundation, the original measured underground water level is below the fill. However, different survey units have different judgments. One is based on the measured value, and the underground water level is very low at this time. The other judgment is to take the highest water line of the surrounding mountains as the highest water line of the high fill. This standard considers that the highest water line of the surrounding mountains will eventually converge the surveyed area to the standard of the highest water line of the surrounding mountains. The above high fill foundation refers to the site or foundation formed by artificial layered filling and using strong compaction, vibration rolling, impact compaction or other technical measures to process, and the filling thickness is greater than 20m.

[0004] The first water level line judgment result is that the water level line is low, and has no influence on the high fill building anti-floating calculation. According to this site water level standard, if the subsequent water level rises, it will cause the buildings in the site to be unsafe. The second water level line judgment result is that the water level line is high, especially in the case where there is no underground water influence, which will cause the construction investment to increase.

[0005] Therefore, how to control the water level of the underground water in the high fill area in the mountainous area to ensure the safety of the building under the premise of reducing the construction investment cost has become a technical problem to be solved. SUMMARY

[0006] In order to make up for the above shortcomings, the present application provides a control floating water method for a high fill industrial park in a mountainous area to solve the technical problems in the prior art.

[0044] The annual maximum runoff flow of surface water flowing from the mountainous area to the high fill industrial park is finally calculated through the surface runoff area and the surface water absorption rate.The maximum annual rainfall in the local catchment area is investigated, and the subsequent collection of surface water and groundwater at the junction of the mountainous area and the high fill industrial park and the collection of surface water in the high fill industrial park are improved, that is, the volume of the subsequent collection buffer equipment, such as the water collecting well 1, the first clean water tank 5 and the second clean water tank 7, is determined according to the maximum annual rainfall; further, the surface runoff area, the height of the mountain, the water content of the soil layer of the mountain, the underground water level, the position and direction of the surface runoff of the mountain, the direction and flow of the underground water are investigated to determine the volume and number of the water collecting well 1.

[0056] Further, the first clean water pool 5 and the second clean water pool 7 are arranged at the lowest position of the high fill industrial park.

[0057] The present application changes from the post control in the prior art to the construction at the same period of the high fill industrial park construction, and takes the first water level line judgment result as the basis to ensure that the water level line is in low position for a long time. Specifically, the annual rainfall of the region is investigated and found out, the height of the mountain around the site, the runoff area of the mountain, the water content of the mountain soil layer and the underground water level of the mountain area are investigated and found out; the original underground water level of the high fill industrial park, the high fill backfill soil depth in the high fill industrial park, the water content of the backfill soil, the final river drainage direction and the river water level around the four sides.
