Problems solved by technology

However, due to the long-distance rain and sewage confluence in the culvert and the accumulation of garbage in the domestic sewage all the year round, the maintenance of the culvert is very difficult, and in the rainy season, due to the blockage of the channel, it is easy to return water and cause urban waterlogging

Embodiment Construction

[0042] Such as Figure 1 to Figure 5 As shown, in order to solve the above technical problems, the present invention adopts the following technical solutions:

[0043] A construction method for an automatic sewage interception culvert, comprising the following steps:

[0044] 1) Preparation of slag removal device 1:

[0045] a. First make the box shell 2 and guide plate 3 according to the design size, install the guide plate 3 on the bottom of the box shell 2, reserve the first installation groove 4 on the top of the box shell 2, and place the guide plate 3 on the bottom of the box shell 2. A reinforcement plate 5 is installed above the installation groove 4, and a slag dump hole 6 is reserved on the right side of the box shell 2;

[0046] b. Next, make the pressing grid 7 and the connecting shaft 8 according to the design size, the length of the connecting shaft 8 is longer than the height of the box shell 2, install the pressing grid 7 under the connecting shaft 8 and fix it...

Abstract

The invention discloses a technical solution of a construction method of an automatic sewage interception closed conduit. The construction method comprises the following steps: 1, making a slag removal device; 2, making a moving device; 3, making a conduit body; and 4, implementing on-site construction. The construction method provided by the invention is not only simple in structural compositionbut also low in closed conduit maintenance cost; the construction method provided by the invention, which is enough in structural intensity, can collect solid waste and residues in the closed conduit,so as to prevent the closed conduit from getting blocked by the solid waste in discharge, and to enhance underwater and rainwater discharge functions of the closed conduit; and therefore, a risk of flood due to river blockage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of urban drainage, and in particular relates to a construction method of an automatic sewage intercepting culvert. Background technique [0002] In low-lying areas such as hills or plains, small wetlands are formed due to the accumulation of rainwater all year round, and abundant shallow groundwater is obtained. The water overflows and forms small rivers and streams. With the development of human society, in the process of urban construction, some small rivers and streams were incorporated into the densely populated downtown area. The birthplaces of these small rivers have been destroyed due to the leveling and reshaping of the original terrain by hardened asphalt roads, construction of sewer pipe networks, and real estate development. [0003] Due to the destruction of the human environment by natural sewage ditches and the occupation of urban land, cement slabs are artificially laid on the original river ...
