Problems solved by technology

[0003] In recent years, in the protection of the embankment bed slope, the "rock barge method", "concrete casting method", "brick laying method" and so on are generally used. These methods can achieve a good slope protection effect, but the cost is high and the raw materials used Transportation is more difficult

Embodiment Construction

[0016] A construction method for underwater mold bag concrete slope protection of a river embankment, comprising the following steps:

[0017] (1) Slope surface treatment: remove obstacles on the slope surface that needs slope protection, including trees and sundries, and at the same time repair the slope of the surface according to the design, and compact it after the slope is formed;

[0018] (2) Mold bag production: choose 260g / ㎡ woven geotextile or 200g / ㎡ woven fabric as the bottom layer of the mold bag, cover the bottom layer of the mold bag with needle-punched non-woven fabric, the thickness of the non-woven fabric is ≥ 2mm; woven geotextile or The woven fabric is used as the outer material of the bag, and the non-woven fabric is used as the inner material of the bag. Firstly, the geotextile or woven fabric and the geotextile are stitched together with a sewing machine, and each 30cm in width and length is stitched into one stitch, and then the bottom of the bag is presse...

Abstract

The invention discloses a construction method for underwater mold bag concrete slope protection of a river bank. The construction method comprises the steps of processing a slope surface, making a mold bag, preparing slurry, paving the mold bag, mounting a grouting machine, grouting, compacting and leveling. The construction operation is convenient and the effect is good. The underwater mold bag slope protection construction process is adopted, so that wood and labor are saved in comparison with a mold plate pouring process and the higher cost is saved in comparison with a stoning method and a bricking method.

Description

technical field [0001] The invention relates to a construction method for underwater mold bag concrete slope protection of a river embankment. Background technique [0002] In the last century, the river embankments excavated in the Daxing water conservancy construction in my country all formed serious collapses, which made the drainage unsmooth and the shipping traffic blocked. Protecting the river embankment slopes has become a key issue in my country's water conservancy construction. [0003] In recent years, in the protection of the embankment bed slope, the "rock barge method", "concrete casting method", "brick laying method" and so on are generally used. These methods can achieve a good slope protection effect, but the cost is high and the raw materials used Transportation is more difficult. Contents of the invention [0004] The purpose of the present invention is to provide a kind of convenient construction, effective river bank underwater mold bag concrete slope ...
