Compound mud-rock flow discharge and guide trough

Abstract

The invention discloses a compound mud-rock flow discharge and guide trough comprising a main discharge and guide trough for the mud-rock flow body under a discharge design standard and discharge and guide trough buffer regions for the mud-rock flow body under the discharge ultra-design standard. The discharge and guide trough buffer regions are located on both sides of the main discharge and guide trough and the boundary of the drainage trough buffer regions are provided with gravity retaining walls. Compared with the prior art, the invention fully utilizes the dangerous regions (a mud-rock flow flooding region under the design standard of main ultra discharge and guide trough) on both sides of the main discharge and guide trough together with the main discharge and guide trough to form the compound mud-rock flow discharge and guide trough, can not only improve the discharge and guide ability of the mud-rock flow discharge and guide trough and enhance the protection capability of the discharge and guide trough on objects on both sides, but also effectively improve the land use ratio and benefit the relieving of the human-land contradiction as for towns and market towns in mountainous areas extremely lack of land resources, and ensure sustainable development in mountainous areas.

Description

technical field [0001] The invention relates to a mud-rock flow prevention technology, in particular to a compound mud-rock flow drainage channel for maximizing land utilization. Background technique [0002] Debris flow disaster is one of the main types of geological disasters in my country. With the development of the mountainous area economy and the deepening of the western development, the demand for debris flow engineering control is becoming more and more vigorous. The debris flow drainage channel is one of the most commonly used debris flow control engineering measures. It has been widely used in the past and will also be necessary in the future debris flow control Will be heavily applied. [0003] The debris flow drainage channel is designed according to certain standards. When the debris flow scale is within the discharge design standard, the debris flow drainage channel can discharge the debris flow smoothly; when the debris flow scale exceeds or greatly exceeds t...

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the prior art, that is, to provide a compound debris flow drainage channel that maximizes the land utilization rate for the current debris flow drainage channel with a single type and low land utilization rate; In the section, combine the urban road with the main channel of the drainage channel, or combine the hydrophilic park with the main channel of the drainage channel; when passing through the farmland section, combine the field road with the main channel of the drainage channel, or combine the temporary cultivated land with the main channel Combination of guide trough and main trough; the use of multiple debris flow drainage troughs instead of a single type not only improves the drainage capacity of the trough and the ability to protect the protected objects, but also improves the land utilization rate
