[0002] The existing municipal pipeline construction is often in a state of working independently and intersecting with each other, resulting in a complex situation of existing pipelines under the road. Concrete inverted wells have the advantages of convenient pipeline relocation and good integrity, so they are widely used in municipal pipeline renovation and expansion projects.

[0003] The inverted shaft wall is a type of excavation method such as a vertical shaft foundation pit. Simply put, it is like digging a well downward, with support while excavating. Among them, the working shaft is a circular working shaft. The inverted shaft wall requires a layer of concrete to be poured on the inner wall of the working shaft. During the pouring process, a steel skeleton is required, and a template is set up, and then concrete is poured into it. During the construction of the shaft concrete building, the conventional vertical transportation method of concrete is to use a concrete delivery pump to pump and supply concrete. However, due to factors such as the geographical location of the construction, the construction environment, and cost control. The original concrete delivery pumping vertical transportation method can no longer meet the existing construction requirements. In order to speed up the construction, an inverted shaft wall concrete pouring device is proposed. Utility Model Content
