Sand blocking device for preventing water and soil loss based on environmental protection

Abstract

The invention provides a sand blocking device for preventing water and soil loss based on environmental protection, and relates to the technical field of river regulation. The problems that residues on a gauze element cannot be automatically cleaned through external wind power in the use process through structural improvement, and intermittent knocking and fixing of the ground nails cannot be automatically achieved through the structural improvement are solved. The sand blocking device for preventing water and soil loss based on the environmental protection comprises a seat body and a stress seat, a frame body is welded to the seat body, a gauze element seat is placed on the frame body, and an auxiliary structure is installed on the gauze element seat. By arranging the gauze element seat and the auxiliary structure in a matched mode, one knocking block is welded to each columnar rod, each knocking block is of a rectangular block structure, and the knocking blocks make contact with ground nails, so that the ground nails can be continuously knocked in the process that the auxiliary structure reciprocates along with the gauze element seat, and then the ground nails can be prevented from loosening.

Description

technical field [0001] The invention belongs to the technical field of river regulation, and more specifically relates to a sand-retaining device for preventing soil loss based on environmental protection. Background technique [0002] The river course has functions such as flood discharge, waterlogging, water diversion, irrigation, shipping, landscape, tourism, etc. There is a large amount of sediment accumulated on the slopes on both sides of the river course. Sand may flow into the channel and deposit at the bottom of the channel. Water and soil loss will reduce the flow section of the channel at the same time. Therefore, it is necessary to install sand-retaining guardrails on both side slopes of the channel. [0003] For example, the application number: CN201910496415.5, the present invention relates to a multi-stage sand-blocking device for water and soil conservation, including a sand-blocking guardrail, a winding device, a positioning sand-proof net and a load-bearing...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a sand-retaining device based on environmental protection to prevent soil loss, so as to solve the existing problem that more sand particles tend to accumulate on the gauze after the existing device has been used for a period of time, thereby increasing the The wind-receiving force of the sand-blocking device, in turn, affects the stability of the sand-blocking device, and the cleaning of residues on the gauze cannot be automatically realized through external wind force during use through structural improvement; moreover, the existing device After a period of use, the ground nails are prone to loosening, and the intermittent knocking and fixing of the ground nails cannot be automatically realized through structural improvements.
