Problems solved by technology

However, in daily life, sundries such as masonry, rubbish, and earth on urban roads often fall into urban pipelines through inspection wells. It will form a tight blockage structure in the pipeline, and the dredging method of conventional high-pressure water guns often cannot effectively dredge it, causing great trouble to the daily maintenance of urban pipelines, seriously affecting the normal work of urban drainage systems, and indirectly affecting people's daily life

Embodiment 1

[0040] See attached figure 1 , an urban pipeline dredging device, comprising a mud pulling pan 3, the mud pulling pan 3 has a circular disc shape as a whole; in the actual construction process, the mud pulling pan 3 is vertically placed in the pipeline 1 to be dredged. At the same time, the dredging device also includes a drive assembly 2 for driving the mud puller 3 to move back and forth along the pipeline 1 to be dredged.

[0041] combined with figure 2, the mud pulling pan 3 includes a disc body 31, and the side edge of the pan body 31 is convex and has a smooth curved surface structure; in this way, it helps to improve the stability of the mud pulling pan 3 moving in the pipeline 1, and reduces the 3 Possibility of jamming in pipe 1. The disc body 31 is concavely formed with arc-shaped grooves 32 near its edge, and the arc-shaped grooves 32 are symmetrically arranged on both sides of the thickness direction of the disc body 31; during the construction process, the arc-...

Embodiment 2

[0047] See attached Figure 4 , a method for dredging urban pipelines using the above-mentioned dredging device, comprising the steps of:

[0048] S1. Dewatering and drainage: Use a mud pump to discharge the sewage in the inspection well, revealing the silt at the bottom of the well.

[0049] In actual construction, in view of the fact that the two adjacent inspection wells of pipeline 1 are far apart, a new inspection well can be excavated between the two inspection wells; for inspection wells that are too deep to be constructed, steel sheet piles can be used for support , and excavate the inspection well to a position 1m above the normal water level, and restore it after the dredging is completed. In addition, since the water level of the pipeline is generally high, and it is mostly connected to the first-stage sump of the sewage treatment plant, direct pumping and drainage cannot achieve the effect of precipitation. When performing step S1, the water bag should be used to ...

Abstract

The invention relates to the technical field of maintenance of urban pipelines, concretely disclosing a dredge device for urban pipelines and a dredge method applying the device. The dredge device forurban pipelines comprises a mud-pulling plate and driving assemblies. The mud-pulling plate comprises a plate body and mud-breaking drills. The driving assemblies comprise steel wire ropes, winding shafts, rotary joints and winding motors. The rotary joints comprise first rotary bodies and second rotary bodies. The first rotary bodies comprise fixedly-connected plates, rotatably-connected platesand pulling cables. At least in circumference, three pulling cables are uniformly arranged on the peripheries. The dredge method for urban pipelines comprises the following steps of diluting sludge, absorbing dirt, intercepting dirt, desilting by machinery, reabsorbing dirt and the like. The diameter of the mud-pulling plate is on the gradual increase. The effect of dredging the pipelines is goodand dredging efficiency is high, which is conducive to reducing dredging difficulty and labor intensity. Normal operation of an urban water drainage system is ensured. The dredge device for urban pipelines and the dredge method applying the device help pick up the speed of creating a harmonious city.

Description

technical field [0001] The invention relates to the technical field of urban pipeline maintenance, in particular to an urban pipeline dredging device and a dredging method using the device. Background technique [0002] With the rapid development of the city, the urban drainage system is also becoming more and more perfect. At present, in the city, there are a large number of drainage pipes underground in the city, and these underground pipes together constitute the urban drainage pipe network. In order to ensure the long-term normal operation of the urban drainage system, special personnel must be assigned to carry out daily maintenance on the urban pipelines. [0003] In the daily maintenance process of urban pipelines, pipeline blockage is one of the common problems; for this kind of problem, the conventional dredging method is to use high-pressure water guns for manual cleaning. However, in daily life, sundries such as masonry, rubbish, and earth on urban roads often f...
