Construction Technology of Concrete Dam Body of Waste Landfill

Abstract

The invention discloses a construction process for a concrete dam body of a garbage landfill site, which comprises the following steps: selecting a site according to the requirements of the landfill site and inspecting the site; drawing a structural diagram of the dam body of the garbage landfill site according to the inspection situation; On the body, set a deformation joint every 15~20m; lay out the line and excavate the base of the dam body step by step, and prepare the formwork at the same time; pour a cushion on the base of the excavated dam body; Divide multiple construction areas on the cushion of the dam body along the preset positions of the deformation joints, and install formwork layer by layer from bottom to top in the manner from deep to shallow and from low to high. After the installation of each layer of formwork is completed, Gravel concrete is poured in the formwork pouring system of this layer to form the first-stage dam body. After the dam body of this layer reaches the design strength requirements, the upper layer of formwork is installed, and so on until the pouring of the top-layer dam body is completed. The construction process of the concrete dam body of the garbage landfill site obtained by the invention has a short construction period and low production cost.

Description

technical field [0001] The invention relates to a garbage landfill, in particular to a construction technique for a concrete dam body of the garbage landfill. Background technique [0002] Garbage landfill is still the most important way to solve domestic garbage in most cities in my country. This requires the construction of garbage landfills. The planning and location of most landfills must meet the requirements of preventing the spread of pollution, large reserves, long service life, and construction. The use of natural valleys + dams is a more economical way to build landfills due to the requirements of short cycle time and low cost of use. In order to facilitate pouring and adapt to the terrain of the valley, the landfill with this kind of site is designed. In order to facilitate the pouring and adapt to the terrain of the valley, the overall elevation section is stepped. In order to facilitate the rapid fall of the garbage to the bottom of the landfill, one side needs t...

Problems solved by technology

Since the dam body is in the shape of a ladder as a whole, and the dam body is low in the middle and slightly high on both sides, the pouring workload of the dam body is very large, and the demand for formwork is also great. If the traditional method is used for construction, there will be a construction period Long, high production cost
