Description
Technical Field
The utility model relates to a construction technical field specifically is foundation ditch excavation steel sleeve supporting device.
Background
In the municipal pipeline work progress, need dig the system and place the foundation ditch of pipeline, often the working face is narrow, if the excavation degree of depth is darker, can't satisfy the requirement of putting the slope, and the danger that the foundation ditch lateral wall takes place to collapse easily, consequently, when building by laying bricks or stones the inspection shaft, if do not have protector, personnel take place danger easily in the construction of darker foundation ditch, consequently it is very necessary to increase safety device.
SUMMERY OF THE UTILITY MODEL
For solving the aforesaid in pipeline construction, the working face is narrow, and the excavation degree of depth is darker and can't put the slope, and the foundation ditch lateral wall takes place easily to collapse danger, when building by laying bricks or stones the inspection shaft, does not have protector, and dangerous problem takes place easily in the construction of personnel in darker foundation ditch, the utility model provides a foundation ditch excavation steel sleeve supporting device can play safety protection's effect to the staff when building by laying bricks or stones the inspection shaft.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: foundation ditch excavation steel sleeve supporting device, including steel sleeve, rings and muffjoint ring, rings weld in the steel sleeve outside, the muffjoint ring cross-section is the H type, the tip suit of steel sleeve is in the recess of muffjoint ring.
Furthermore, the number of the lifting rings is 3-5, and the lifting rings are uniformly distributed on the outer side of the steel sleeve.
Further, the hoisting ring is located 20cm away from the upper end face of the steel sleeve.
Furthermore, the thickness of the side wall of the steel sleeve is 10mm, the height is 2m, and the inner diameter is 2.5 m.
Furthermore, the diameter of the hanging ring is 8cm, and the diameter of the section of the hanging ring is 2 cm.
Further, the inner diameter of the sleeve connecting ring is 2.5m, and the width of the groove is 10 mm; the whole width of sleeve connecting ring is 20mm, and the height is 25 mm.
The utility model discloses a technological effect and advantage: the utility model provides a foundation ditch excavation steel sleeve supporting device simple structure, rings and the prefabricated welding of steel sleeve are good, can realize simple hoist and mount, use the spigot-and-socket joint of telescopic link between two sections steel sleeves to connect, stable in structure, easy operation, the branch of being convenient for tears open, but cyclic utilization effectively reduces the excavation and puts the slope proportion, and personnel are under construction in darker foundation ditch, can effectively ensure constructor's safety, improve the efficiency of construction, reduce construction cost.
