Construction method for composite assembly type torrent groove

Abstract

The invention relates to a construction method for a composite assembly type torrent groove. The construction method includes the following steps that firstly, construction preparation is made; secondly, torrent groove laying groove digging construction is conducted; thirdly, sliding supporting cross beam supporting is conducted; fourthly, torrent groove laying groove surface finishing is conducted; fifthly, groove bottom mortar layer injection is conducted; sixthly, torrent groove plate laying is conducted; and seventhly, torrent groove plate bottom airtight grouting is conducted. The construction method has the beneficial effects that sliding rails are laid on groove side soil bodies; sliding rail connecting bodies and a supporting cross beam are sequentially arranged on the sliding rails; and the moving and installation difficulty of the supporting cross beam is lowered. By means of the construction method, when a sliding scraping plate is used for conducting torrent groove laying groove finishing construction, water pipe nozzles on the lower surface of a sector water spraying pipe can be synchronously used for conducting water spraying construction, the finishing construction difficulty can be lowered, and the construction environment is protected. Residue wrapping cloth is arranged on the sliding scraping plate, a residue lifting rod can be used for rapidly lifting the residue wrapping cloth, and groove residues can be rapidly removed.

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
