A kind of construction method of thin-walled concrete high wall

Abstract

The invention discloses a construction method for a thin-walled concrete high wall, comprising the steps of: 1. assembling the wall reinforcement mesh and erecting a temporary scaffold; 2. using a wall reinforcement mesh hanger to lift the wall reinforcement mesh; 3. thin-wall high wall Formwork installation and reinforcement; 4. Positioning and fixing of the vibrating rod and the flexible shaft of the vibrating rod; 5. Pouring and vibrating cast-in-place concrete from bottom to top; 6. Removing the thin-walled high-wall formwork reinforcement structure. The present invention adopts the bottom positioning rod and a plurality of standard positioning rods which are sequentially arranged on the upper side of the bottom positioning rod from bottom to top to limit the flexible shaft of the vibrating rod between the steel meshes of the walls on both sides, which can effectively avoid floating rods and sticking rods. It can effectively control the quality of vibration, and has strong advantages in high-wall concrete pouring and vibration construction, and solves the difficulty of vibration caused by large height difference and limited space in the process of high-wall concrete pouring. question.

Description

technical field [0001] The invention belongs to the technical field of thin-wall concrete high-wall construction, and in particular relates to a thin-wall concrete high-wall construction method. Background technique [0002] In the construction of high walls in construction projects, for the convenience of construction, layered pouring is often used, and the layered height is generally not greater than 3m. 50cm thin-walled structure, and for the sake of anti-leakage considerations, it is often required to minimize horizontal construction joints, the single-layer pouring height is high, and tie rod holes are not allowed. For example, the dock wall of a dock project is a buttress-type thin-walled wall structure with a total height of 13.8m. According to the design requirements, the wall in the middle vertical section (excluding the lower toe wall and the upper structure part) requires one-time pouring and single-layer concrete pouring The height is 8.65m, and the wall thickne...

Problems solved by technology

Under such construction conditions, there will be a series of problems such as high requirements for formwork reinforcement, difficulty in installing steel bars, and difficulty in controlling the vibrating effect of the lower concrete.
