Construction method of efficient water-saving cast-in-place irrigation and drainage closed conduit

Abstract

The invention relates to a construction method of an efficient water-saving cast-in-place irrigation and drainage closed conduit. The construction method comprises the following steps that S1, a containing barrel is fixedly arranged on the lower surface of a closed conduit body; S2, a filter barrel is placed in the containing barrel; S3, a filter plate is fixed in a closed conduit body; S4, the closed conduit body is covered with a plurality of cover bodies, and two adjacent cover bodies are arranged at intervals; and S5, two supporting plates are fixed to the two cover bodies correspondingly, two rotating shafts fixed to a worm are arranged on the two supporting plates in a penetrating mode correspondingly, the rotating shafts are rotationally connected with the supporting plates, the two ends of a bearing plate are fixedly connected with the two supporting plates correspondingly, a shaft sleeve on a turbine is arranged on the bearing plate in a penetrating mode, the shaft sleeve is rotationally connected with the bearing plate, the bottom end of a lead screw is fixedly connected with a bearing rod in the filter barrel, the top end of the lead screw sequentially penetrates through the shaft sleeve and the turbine, and the lead screw is in threaded fit with the shaft sleeve and the turbine. According to the construction method, pollutants in the closed conduit body can be conveniently cleaned.

Description

technical field [0001] The application relates to the field of water supply and drainage, in particular to a construction method for an efficient water-saving cast-in-place drainage and irrigation culvert. Background technique [0002] The culvert is a built river channel, which is a pipe type. There is no water visible on the surface, and there is basically no evaporation, so water transportation is more economical. [0003] In the related art, the Chinese patent whose authorized announcement number is CN211873254U discloses an environment-friendly drainage culvert, which can also be called a high-efficiency water-saving cast-in-place drainage and irrigation culvert. , the drainage channel is covered with rainwater grates at intervals, and a permeable cover plate mounted on the drainage channel is arranged between two adjacent rainwater grates, and it is characterized in that: the drainage channel is provided with a A runoff pollution control unit for controlling runoff po...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor found the following defects in the process of long-term observation: Although the permeable bricks can filter the pollutants in the rainwater, they cannot clean the pollutants in the underdrain body in time. When the pollutants accumulate too much, the pollutants will block the underdrain body
