Construction method of pipe-protection-free integrated check dam

Abstract

The invention provides a construction method of a pipe-protection-free integrated check dam. The method comprises the following steps that a loess curing agent mixer is used for mixing a mixture, and the mixture comprises loess and a loess curing agent; the mixture is slipped into a loess extruder to be extruded into an anti-scouring protection layer; after the anti-scouring protection layer has certain strength, the rolling and filling construction of an inner side homogeneous earth dam body is started; and the steps are repeated until a dam crest elevation is achieved. According to the method, before construction of the homogeneous earth dam body, the protection layer similar to a trapezoid is manufactured through the loess extruder, then the homogeneous earth dam body is laid and fills the inner side of the protection layer according to the design, plane rolling is conducted through a vibration roller, and compared with a traditional construction method, the prepared pipe-protection-free integrated check dam protection layer is high in construction efficiency, the protection layer can adapt to uneven settlement of the dam body, is high in anti-scouring capacity, can effectively solve the problem that the check dam is prone to break when passing through standard flood, and can simplify engineering management and protection tasks.

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
