The Construction Method of Composite Assembled Rapid Flume

Abstract

The invention relates to a construction method of a composite assembly type rapid trough, comprising the following steps: 1) construction preparation; 2) excavation construction of a rapid trough laying groove; 3) slidable supporting crossbeam supporting; 4) finishing of the rapid trough laying groove surface; 5) Mortar layer injection at the bottom of the tank; 6) Laying of the rapid flow trough; 7) Sealed grouting at the bottom of the rapid flow trough. The beneficial effects of the present invention are: the present invention lays the sliding track on the soil body at the side of the groove, and sequentially arranges the sliding rail connecting body and the supporting beam on the sliding track, which reduces the difficulty of shifting and installing the supporting beam; the present invention adopts When the sliding scraper is used for repairing the rapid flow trough layout, the water spraying construction is carried out synchronously through the water pipe nozzle on the lower surface of the fan-shaped water spray pipe, which can reduce the difficulty of repairing and protect the construction environment; set the residue bag on the sliding scraper Cloth, the residue wrapping cloth can be quickly pulled up through the residue boom, realizing the rapid removal of the groove residue.

Description

technical field [0001] The invention relates to a construction method of a composite assembled rapid flow trough, which belongs to the field of civil engineering and is suitable for slope drainage engineering. Background technique [0002] During the construction of civil engineering slopes, the layout quality and drainage effect of the drainage system often have a significant impact on the stability of the slope and the benefits of engineering construction. At present, cast-in-situ concrete materials or mortar block stone materials are usually used in the construction of rapid flow troughs. The engineering construction technology is relatively complicated, the masonry work is large, the repair construction is difficult, and the environmental protection is difficult. [0003] In the prior art, there is a design and construction method of "shingle-type" reinforced concrete drainage rapids. In view of the defects of the mortar-built gravel rapids of the main highway, the conce...

AI Technical Summary

Problems solved by technology

This construction method can reduce the problems of masonry rapid flow trough water seepage, water leakage, settlement deformation and other water damage to highway subgrade scour caused by drainage, but the integrity of the "shingled" reinforced concrete drainage rapid trough is poor, and the site laying There is a strong uncertainty about the quality
