Description

Hydraulic engineering soil retaining plate

Technical Field

The utility model relates to the technical field of water conservancy, in particular to a water conservancy project soil retaining plate.

Background

With the continuous reformation of hydraulic engineering retaining walls by mankind, hydraulic drainage has become an indispensable part in hydraulic engineering retaining walls, and the existing hydraulic engineering retaining walls are generally used for preventing slope landslide and soil erosion. The water and soil loss is a phenomenon that water and soil are simultaneously lost due to the influence of natural or artificial factors, rainwater cannot be absorbed in situ, flows down and washes the soil, and along with the excessive cutting of trees and excessive grazing of people, the water and soil loss is more and more serious, so that the problems of vegetation protection and water and soil loss prevention are more and more researched by people, and the problems of ecological environment, geographical disasters and the like caused by the water and soil loss are urgently restrained, so that the water and soil loss is prevented.

For hydraulic engineering retaining plates, there are many existing technologies, such as:

chinese patent publication No. CN217104910U discloses a hydraulic engineering is with filtering soil guard board, including the base tank, the left side fixedly connected with of base tank keeps off the soil guard board, keeps off the left side fixedly connected with filter of soil guard board, and the cavity has been seted up on the right side of filter, and the filtration pore has been seted up in the left side of filter, and the through-hole has been seted up to the inner chamber of soil guard board, and equal sliding connection in both sides of base tank inner chamber has the backup pad. When using, through the setting of base box, retaining board, filter, cavity, filtration pore and through-hole, can be in the during operation of keeping earth, the rainwater flows to the cavity through the filtration pore, then in the rethread through-hole flows to the river, realizes the water and soil separation to realize filtering silt, firm soil prevents the purpose that the soil and water loss takes place, and setting up of backup pad, spacing awl, thread bush and threaded rod can be with the more stable firm of base box installation, can make the soil retaining ability of device stronger.

Therefore, most of hydraulic engineering retaining plates comprise retaining plates, rainwater flows into the cavities through filter holes and then flows into rivers through holes by arranging filter plates and cavities, but the retaining plates bear the pressure of sand from the side faces, and when the cavities are arranged on the side faces of the retaining plates, the cavities can not bear the lateral pressure to collapse, and meanwhile, a plurality of through holes are formed in the retaining plates, so that the bearing capacity of the retaining plates can be reduced.

In view of this, we propose a hydraulic engineering retaining plate.
