Abstract

The construction method of a self-waterproof waterway structure with a complex section of the present invention belongs to the field of building construction. In the present invention, the cantilevered side wall of the C-shaped second waterway is poured twice, the first pouring is on the lower surface of the pick plate roof, and the second is pouring. Pour the pick plate roof again. The inner formwork of the cantilevered side wall of the second water channel for the first pouring adopts the method of hanging formwork, so that the lower surface of the hidden groove of the picket plate is open, and the surface can be closed manually during pouring, and the pouring effect is good. During the second pouring, the inner formwork of the cantilevered side wall of the second waterway is removed, and the inner top formwork of the cantilevered side wall of the second waterway is installed, and then the top plate of the cantilevered slab is poured. The construction quality can be guaranteed. After the pouring is completed, the cantilevered side of the second waterway The roof formwork inside the wall is easy to remove. The wedge-shaped formwork is used when pouring the thickened side wall of the first water channel, which effectively ensures the pouring quality of the thickened side wall of the first water channel. The waterway structure of the invention has good bearing capacity, good waterproof effect and good construction quality.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for a self-waterproof waterway structure with complex sections. Background technique [0002] The existing formwork technology is relatively easy to handle for cast-in-place concrete structures with regular structures and simple shapes. However, for the construction of cast-in-place reinforced concrete waterway structures with complex section shapes, high precision and quality requirements, and the need to meet the self-waterproof performance of concrete, there are deficiencies such as backward technology, poor construction quality, and difficulty in meeting design requirements. Contents of the invention [0003] The object of the present invention is to provide a construction method of a self-waterproof waterway structure with a complex section to solve the above technical problems. [0004] In order to solve the above technical problems,...
