Anti-collapse device for underground cable channels in buildings

Abstract

The invention discloses a collapse prevention device of a building underground cable channel, and relates to the technical field of building cable auxiliary equipment. The collapse prevention device comprises a slurry pump and a soft solidification liquid pipe. The output end of the slurry pump is connected and communicated with the soft solidification liquid pipe through a liquid guide pipe. A switching valve is arranged on the liquid guide pipe. The input end of the slurry pump is communicated with a liquid suction pipe, and the other end of the liquid suction pipe is communicated with a solidification liquid bucket. A solidification liquid channel is arranged in the soft solidification liquid pipe. Annular grooves are evenly distributed in the outer surface of the soft solidification liquid pipe, and liquid outlets communicated with the solidification liquid channel are evenly formed in each annular groove. Each annular groove is sleeved and connected with a liquid spray ring matched with the corresponding annular groove, the liquid spray rings are in rotary sealing fit with the soft solidification liquid pipe, and the diameter of the liquid spray rings is smaller than that of the soft solidification liquid pipe. Backwashing spray through holes are evenly distributed in the liquid spray rings in the circumferential direction. The collapse prevention device is simple in structure, convenient to use and low in application cost, the channel can be effectively prevented from collapsing, and construction of construction personnel is facilitated better.

Description

technical field [0001] The invention relates to the technical field of cable auxiliary equipment for construction. Background technique [0002] In the process of building construction, cables often pass through the ground, so we need to make a tunnel underground to pass the cables through. However, in the past construction, due to the loose soil, it is prone to subsidence. If the subsidence of the soil around the underground cable is different, the underground cable will be tight or even broken. The common solution now is to excavate the soil around the underground cable burial site, and use a composite foundation to reinforce the soil around the burial site. Although this method effectively solves the cable tension caused by the subsidence of the buried soil, it has high cost and long construction period, and the underground cable may be damaged during the excavation of the soil around the buried cable and the formation of the composite foundation. Collapse will occur, a...

Problems solved by technology

Although this method effectively solves the cable tension caused by the subsidence of the buried soil, it has high cost and long construction period, and the underground cable may be damaged during the excavation of the soil around the buried cable and the formation of the composite foundation. Collapse will occur, affecting the passage of cables, and sometimes it is necessary to re-open an underground cable passage, which will not only affect the construction process of the construction personnel, but also waste time
