Basement protection wall concrete pouring construction technology

Abstract

The invention provides a basement protection wall concrete pouring construction technology. The technology comprises the following steps that a foundation pit is dug, a form frame is arranged, a surface form is installed, a mold cavity is formed between the surface form and the inner wall of the foundation pit, a rebar frame is arranged in the mold cavity, concrete is poured layer by layer, and curing is carried out on a basement protection wall. According to the technical scheme of the technology, the rebar frame is embedded in the concrete, the structure strength and the bearing capacity ofthe basement protection wall are enhanced, through the adoption of the steel surface form, the flatness of the surface of the basement protection wall is improved, by adopting a layer-by-layer pouringconstruction process, air doped in the concrete can sufficiently escape, the concrete is compact in condensation, the concrete engineering quality is improved, cracks can be effectively avoided on the surface of the concrete by flattening the concrete in an initial setting state, sufficient maintenance is conducted on the surface of the poured and formed basement protection wall, and the concreteengineering construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a concrete pouring construction process for a basement retaining wall. Background technique [0002] With the continuous development of modern urbanization, the scale of the city is getting bigger and bigger, and the urban ground space has gradually been unable to meet the needs of people's production and life. People turn to expand the space below the ground. Among the basements built for various purposes, the basement The parapet walls need to be connected with the corresponding buildings on the ground, so the requirements for their bearing capacity and structural strength are high. The existing basement parapet walls are generally made of concrete. If the construction process is not handled properly, the concrete will A large amount of air will be mixed in, which will affect the construction quality and bearing strength of the basement parapet.
