A basement waterproofing construction method

Abstract

The present invention discloses a construction method, aiming to provide a basement waterproofing construction method with good waterproofing effect and convenient construction. The key points of the technical scheme are as follows: after a basement pit structure is formed by excavation, a pre-set built-in baffle structure is used, and stones are laid on the area surrounded by the built-in baffle structure, and cement is poured in advance, so that the formed local area is flush with the built-in baffle structure. Because the built-in baffle structure is arranged in advance, a good protection area can be formed before pouring, and the integrity is higher. Moreover, the built-in baffle structure can improve the waterproofing protection effect on the outer wall of the basement, greatly improving the strong waterproofing performance in the event of sinking. By bonding multiple layers of waterproof membranes, a first and a second waterproof layer structure are formed, thereby greatly improving the waterproofing effect of the underground type, and the practicality is greatly improved. The present invention is suitable for the field of building construction technology.
