Horizontal construction seam construction method of refuse incineration power plant structure pool project

Abstract

The invention discloses a horizontal construction seam construction method of a refuse incineration power plant structure pool project. The horizontal construction seam construction method comprises the following steps that a steel plate waterproof belt is mounted at the horizontal position of a construction seam, the steel plate waterproof belt is fixed by adopting reinforcing steel bars, the lower part is borne by adopting rebar cross braces, the two sides are slantly welded and fixed by adopting rebars, the mixed concrete is poured in a form board on the lower part of the construction seam,the surface of the concrete on the lower part of the construction seam is subjected to scabbling, laitance removal and water wetting, a paper sponge strip is pasted to the concrete below the construction seam, square timber is horizontally mounted on the lower face of the sponge strip, the form board on the upper part is placed on the square timber, the form board is tightly adhered to the papersponge strip, the upper layer concrete must be poured before the lower layer concrete is initially set, and after the upper form board is removed, waterproof mortar is applied on the inner side and the outer side of the horizontal construction seam. The horizontal construction seam construction method meets the anti-leakage construction requirement of the horizontal construction seam, can be applied to structure projects such as rubbish bins, slag bins and percolate pools in various refuse incineration power plants, and is safe and reliable, short in construction period, and outstanding in economic benefit.

Description

Technical field: [0001] The technology of the present invention relates to a construction method of construction joints for anti-leakage of structures in garbage power plants, in particular to a construction method for horizontal construction joints in pool engineering of structures in waste power plants. Background technique: [0002] In recent years, with the government's intensification of environmental engineering governance, a large number of waste-to-energy plant projects have sprung up across the country. Among them, large-scale pool projects such as garbage bins and slag bins are key structural projects for the technology of waste-to-energy power plants. Large-scale and large-scale reinforced concrete construction will inevitably cause construction joints to be left during construction. As a liquid or semi-liquid "container" pool project, if the quality of the construction joints is not properly handled during construction, leakage will occur. It will cause secondary...

Problems solved by technology

[0004] For the horizontal construction joints that need to be waterproofed, the methods used are: circular strip-shaped water-stop strips, which can be pressed on the surface of the wall concrete when the foundation is poured. The construction is simple, but the water-stop effect is not good; Water belt: The water stop belt is flexible, difficult to fix during installation, and it is easy to be squeezed and deformed when pouring concrete, which may easily cause local water leakage, and the rubber water stop belt is easy to age and fail, which is not conducive to the long-term structure Use; steel plate waterstop: 300~400mm wide and 2~3mm thick steel plate is used as the waterstop at the construction joint, which has a good waterproof effect, but now it is clamped and fixed on both sides of the pool wall by steel bar spot welding to fix the waterstop In the middle or upper and lower ends of the belt, the construction joints are affected by the shear force and the waterstop is easy to dislocate and shift away from the center position, and the ordinary steel plate is difficult to withstand the corrosive construction environment.
