Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] A horizontal construction method for underwater mold bag concrete, comprising the following steps:

[0042] S1, construction preparation, prepare the mold bag with polypropylene woven fabric, sew the inner layer of non-woven fabric in the mold bag, and bond the mold bag and the inner layer of non-woven fabric together by hot pressing.

[0043] Wherein when mold bag is made, sew 100cm wide anti-filter cloth in the length direction limit of mold bag, sew 300cm wide anti-filter cloth in width direction limit. At the same time, two rows of 24 grouting openings are sewn on the mold bag, and the diameter of the grouting opening is 18-20cm and the length is 50-80cm.

[0044] S2, Reinforcement surface trimming, use block stones to fill the flush pit on the slope, then lay sand and gravel on the block stone, and after scraping the sand and gravel, lay a layer ...

Abstract

The invention discloses a horizontal construction method of underwater mold bag concrete, which relates to the field of water conservancy engineering and includes the following steps: S1, construction preparation; S2, repairing the reinforcement surface; S3, laying and fixing the mold bag; S4, preparing concrete; S5, Concrete filling of mold bag; S6, underwater inspection. The invention has the following advantages and effects: the above-mentioned construction method is simple and can be directly repaired at the damaged position, and compared with the scheme of building cofferdams on the river course, the construction period can be greatly shortened. At the same time, a large amount of earthwork excavation is reduced, which not only saves investment, but also protects the environment. And during the construction process, it will not affect the normal release of water from the sluice, and there will be no pollution to water resources.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a horizontal construction method for underwater form bag concrete. Background technique [0002] Water conservancy engineering is a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. It usually requires the construction of dams, dikes, spillways, sluices, water inlets, channels, crossings, rafts, fish Different types of hydraulic structures such as roads can be used to achieve the purpose. [0003] After the traditional sluice is used for a long time, due to the erosion of the water flow, the slope of the sluice will be damaged. At this time, the damaged position needs to be repaired. However, when traditional sluices are repaired, it is usually necessary to build cofferdams on the river channel and then repair the sluices, which increases the construction period and ne...
