Underwater concrete pouring process in building construction
The invention relates to the technical field of building construction, in particular to an underwater concrete pouring process in building construction. The underwater concrete pouring process comprises the following steps that S1, a cofferdam cover is manufactured around an underwater concrete pouring area; S2, water in a covering area of the cofferdam cage cover is pumped out through water pumping equipment, so that the covering area of the cofferdam cage cover is in a water-free state; S3, settlement observation is carried out on the covering area of the cofferdam cage cover, and follow-up operation is carried out until the safety standard is met; S4, soil is taken out of the water-free cofferdam cage covering area through an instrument, mud soil and the like which are doped in the covering area of the cofferdam cage cover and are large in sand content are taken out, and a foundation pit is dug out; and S5, water seepage prevention treatment is carried out on the foundation pit, and then water seepage prevention treatment is carried out in the foundation pit. According to the underwater concrete pouring process in building construction, the waterproof effect can be well achieved in the pouring process and the subsequent using process of underwater concrete, the convenience of the underwater concrete in the pouring process is improved, and the safety of the underwater concrete in the actual using process can be improved.
本发明涉及建筑施工技术领域，尤其涉及建筑施工中对水下混凝土的浇筑工艺，包括以下步骤：S1、在水下混凝土浇筑区域周围制作围堰笼罩；S2、利用抽水设备将围堰笼罩罩设区域内的水分抽干，使得围堰笼罩所罩设区域处于无水状态；S3、对围堰笼罩罩设区域进行沉降观测，直至达到安全标准之后进行后续操作；S4、通过采用器械对无水的围堰笼罩罩设区域内进行取土，取出掺杂在内部的含沙量较大的泥浆泥土等，并刨出基坑；S5、对基坑进行防渗水处理，而后在基坑内进行防渗水处理。本发明使得水下混凝土在浇筑的过程以及后续的使用过程中能够较好地达到防水的效果，提高水下混凝土在浇筑过程中的方便，并能够提高其实际使用过程中的安全性。
