Problems solved by technology

Rainwater or sewage flows in the drainage pipe. Although the diameter of the pipe is large, the flow rate is not high in most cases, and the flow rate is not high. The dirt in the water flow is easy to settle at the bottom of the pipe.
This will lead to two problems: first, the effective flow of the pipeline will be reduced, which will easily lead to limited drainage during heavy rain; second, the deposited dirt can decompose and produce combustible gas, which will diffuse in the pipeline or may leak into the pipe gallery , causing a serious safety hazard
However, due to limited space and other factors, it is difficult for the comprehensive utility corridor to realize such a design

Embodiment 1

[0026] Embodiment 1 is a flushing device for flushing drainpipes using drainage facilities in a pipe gallery. Such as figure 1 , figure 2 , image 3 As shown, the device includes a horizontal drainage pipe 1, and a flushing port 2 through the pipe wall is opened on the top of the pipe body. The flushing port is connected with the fixed pipe 4 through the flange 5, and the flange on the fixed pipe is integrally formed. The front end of the fixed pipe stretches into the drain pipe, and the rear end can be connected with a flushing water source. The front end of the fixed pipe is connected to the rear end of the flushing extension pipe 6, and the front end of the flushing extension pipe is connected to the rear end of the flushing nozzle 3. The front end of the flushing nozzle is located at the bottom of the inner side of the drain pipe, and the flushing direction is towards the downstream direction of the drain pipe. In this example, the connection methods of the fixed pipe...

Embodiment 2

[0030] Embodiment 2 is a flushing unit that utilizes the drainage facilities in the pipe gallery to flush the drainage pipes. Such as Figure 5As shown, the flushing unit is located in the pipe gallery 11, and includes the flushing device in Embodiment 1, the parallel drainage pipe 1 and the water supply pipe 7, and the sump 13 of the auxiliary facilities of the pipe gallery. The sump pit is concave and located at the bottom of the pipe gallery where it is located, and a water pump 14 and a liquid level gauge 17 are arranged in the sump pit. The sump can usually collect a small amount of seepage water in the pipe gallery. The water pump is connected to the sump drainage pipe 15, and the sump drainage pipe extends upwards and opens above the outside of the pipe gallery. A three-way pipe is arranged on the drainpipe of the sump, and another passage of the three-way pipe is connected to the drainpipe through a connecting pipe 9 . The sump drain pipe and connecting pipe are pro...

Embodiment 3

[0035] Embodiment 3 is a flushing system that utilizes the drainage facilities in the pipe gallery to flush the drainage pipes. Such as Figure 5 As shown, the system includes a pipe gallery 11. The pipe gallery in this example includes two parts, the left and the right, which are independent of each other. The left side is the water supply and drainage pipe compartment, and the right side is the cable compartment. The scheme of the present embodiment is located in the water supply and drainage pipeline compartment on the left side.

[0036] In this example, the flushing system using the drainage facilities in the pipe gallery to flush the drainpipes is provided with several flushing units as in Example 2 along the length of the pipe gallery, and each flushing unit is located at the position where a sump is provided in the pipe gallery . In this example, the end point of the sump drain pipe of the flushing unit is set on the upper left of the pipe gallery and directly discha...

Abstract

The invention discloses a flushing device for flushing a drainage pipe by utilizing a drainage facility in a pipe gallery. The device comprises the drainage pipe; the drainage pipe is provided with aflushing port running through the pipe wall of the drainage pipe, and the flushing port is connected with a flushing nozzle. The front end of the flushing nozzle is positioned at the bottom of the inner side of the drainage pipe. The device has the advantages that the drainage facility and water supply pipes in the pipe gallery are reasonably utilized, the flushing problem of a drainage pipelinesin the comprehensive pipe gallery is effectively solved, the cost is low, and the operation is easy.

Description

technical field [0001] The invention relates to the field of municipal construction, in particular to a flushing device for flushing drainpipes using drainage facilities in a pipe gallery, and a flushing unit and a flushing system developed on the basis of the flushing device. Background technique [0002] The comprehensive pipe gallery is a structure and ancillary facilities built underground in the city to accommodate two or more types of urban engineering pipelines. Since all kinds of pipelines are unified in the pipe gallery, the maintenance and management of the pipeline is carried out in the pipe gallery, so there is no need to open the pipeline during maintenance and overhaul. Excavate roads, thereby avoiding the economic waste and inconvenience to citizens caused by repeated excavation and backfilling during maintenance of various pipelines. Chinese patent document CN107630464A disclosed on January 26, 2018 "a comprehensive pipe gallery with rainwater collection, sto...
