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 an underwater mold bag concrete horizontal construction method, and relates to the field of water conservancy projects. The method includes the following steps that S1, construction preparations are made; S2, reinforcement face finishing is conducted; S3, mold bag laying and fixing are conducted; S4, concrete arrangement is conducted; S5, mold bag concrete filling is conducted; and S6, underwater inspection is conducted. The method has the following advantages and effects that the construction method is simple and convenient, and repairing can be directly conducted at damaged positions; and compared with a scheme of building a cofferdam on a riverway, the construction period is greatly shortened. Meanwhile, a large amount of earthwork excavation is reduced, investment is saved, and environment protection is achieved. In the construction process, normal water discharge of a water gate is not influenced, and no pollution is caused 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...
