Construction method of ecological prefabricated reinforced-concrete torrent channel drainage system

Abstract

The invention relates to a construction method of an ecological prefabricated reinforced-concrete torrent channel drainage system. The construction method mainly includes prefabricating a torrent channel, prefabricating grass planting mould boxes, constructing channels, mounting force-eliminating steps, mounting standard prefabricated sections of the torrent channel, mounting a prefabricated sump,mounting the grass planting mould boxes and mounting a spherical detachable filter screen. The prefabricated sections of the torrent channel are fastened together in a 'stacking type' way and are integrally bundled together by a steel cable, the two ends of the steel cable are drawn onto pre-embedded pull rings of the prefabricated sump, and the grass planting mould boxes are embedded into the tops of the prefabricated sections of the torrent channel. The torrent channel drainage system based on the prefabricated design concept has the advantages of convenience and rapidness in mounting, highconstruction speed, ecological environment protection and the like; damage, such as hollow-out and scouring, of drained water to roadbeds due to the problems such as water seepage, water leakage andsettlement deformation of brickwork-type torrent channels is avoided, and good economic and technical benefits are achieved.

Description

technical field [0001] The invention relates to a construction method of an ecological prefabricated reinforced concrete rapid trough drainage system, belongs to the field of highway engineering, and is suitable for vertical drainage construction at steep slopes of embankments and road cuttings. Background technique [0002] In highway engineering, the jet trough is mainly used for drainage and to slow down the water flow speed, which plays a great role in protecting the roadbed. Whether the structure of the jet trough is reasonable or not is directly related to the safety of the subgrade. In the past, embankments were often used in construction. Due to the difficulty of standardization of raw materials and the lack of skilled workers in the masonry team, it is difficult to control and guarantee the quality of the construction process for the drainage jet channel of the slope mortar rubble structure. As a result, the drainage jet channel is prone to insufficient mortar. The ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of the traditional embankment side slope masonry rubble rapid flow channel that the mortar is not full, the joints fall off, seepage, water leakage, easy deformation, cracking, and cause subsidence, deformation and collapse of the roadbed, and propose an ecological prefabricated The construction method of the prefabricated reinforced concrete rapid trough drainage system, the method installs the prefabricated rapid trough section by section from bottom to top, and "shingled" concave-convex buckles of the adjacent prefabricated rapid trough sections, and at the same time connects the two ends of the steel cable by Go through the steel cable hole of the anti-slip tooth from bottom to top, and use the anti-slip tooth at the bottom to prevent sliding, and use the upper surface to reduce the flow energy of the water, and then tie the two ends of the steel cable to the pre-buried pull of the prefabricated sump ring, and then insert the prefabricated grass planting mold box into the groove of the side wall of the prefabricated section
