A construction method for a pipe-free and protective integrated check dam

Abstract

The invention provides a construction method for a tube-free and protective integrated check dam, comprising the following steps: using a loess curing agent mixer to mix a mixture, the mixture including loess and a loess curing agent; slipping the mixture into the loess to squeeze The press is used to extrude the anti-scouring protective layer; after the anti-scouring protective layer has a certain strength, the rolling and filling construction of the inner homogeneous earth dam body is started; the above steps are repeated until the dam crest elevation. In the present invention, before the construction of the homogeneous earth dam body, a loess extrusion machine is used to make a protective layer similar to a trapezoid, and then the homogeneous earth dam body is paved and filled on the inner side according to the design, and the vibrating roller is used for plane rolling. Compared with the traditional construction method, the protection layer of the integrated check dam prepared by the invention has high construction efficiency, can adapt to the uneven settlement of the dam body, has strong anti-scouring ability, and can effectively solve the problem of excessive flooding in the check dam. The problem of dam failure can be simplified, and the task of engineering management and protection can be simplified.

Description

technical field [0001] The invention relates to the technical field of check dam construction, in particular to a construction method of a tube-free and protective integrated check dam. Background technique [0002] In the Loess Plateau area of ​​Northwest my country, soil erosion is serious. In order to intercept the silt formed by water and soil erosion, a series of cascade check dams were built in the trenches. However, the check dams currently built generally have low flood control standards. When the dams are overturned by excessive floods, it is easy to cause a single check dam to break and be washed away, and the flood of the dam break will wash away the downstream cascade check dams, thus forming a chain reaction. ; If the flood control standard is raised, the project investment will certainly be increased; and because the quantity of check dams is large and the distribution is scattered, the management and protection tasks of the water administrative department are ...

Problems solved by technology

However, the check dams currently built generally have low flood control standards. When the dams are overturned by excessive floods, it is easy to cause a single check dam to break and be washed away, and the flood of the dam break will wash away the downstream cascade check dams, thus forming a chain reaction. If the flood control standard is raised, the investment in the project will inevitably be increased; and due to the large number of check dams and scattered distribution, the management and protection tasks of the water administrative department are huge, and the enthusiasm for building check dams in various places is not high
