Problems solved by technology

The current support schemes mostly use steel support, reinforced concrete support or brick support. The traditional support methods are more restrictive and the construction process is complicated. Some support forms, such as reinforced concrete support, require large-scale machinery for demolition. , not convenient enough, and the supporting material cannot be reused, and the investment is large
However, the general foundation pit support is mostly a temporary structure, and the investment is too large and it is easy to cause waste

Abstract

The invention discloses a quick and convenience supporting device for circular well pit construction. The supporting device is positioned in a circular well pit and comprises a center supporting rod,telescopic side supporting rods, connecting rods and waist beams. The center supporting rod is arranged at the center of the circular well pit, the telescopic side supporting rods are distributed at intervals on the lateral side of the center supporting rod, one end of each telescopic side supporting rod is in bolted connection with the center supporting rod, and the other end of each telescopic side supporting rod is in bolted connection with the corresponding waist beam and abutted against the wall of the well pit through the corresponding waist beam. Two ends of each connecting rod are connected with the center supporting rod and the corresponding telescopic side supporting rod to form triangular fixation. The supporting device has advantages that angles and sizes of supporting parts can be adjusted conveniently to meet supporting requirements of foundation pits in different sizes, and high supporting stability, simplicity in operation, low cost and recyclability are realized.

Description

technical field [0001] The invention relates to the field of foundation pit support, in particular to a quick support device for circular well pit construction. Background technique [0002] At present, support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall and the surrounding environment. In the process of excavating foundation pits, because there are usually various structures such as traffic arteries, built buildings or pipelines around, protecting the safe use of surrounding structures is an important content of foundation pit support. Safe and reasonable support structures The importance of foundation pit engineering is self-evident. The current support schemes mostly use steel support, reinforced concrete support or brick support. The traditional support methods are more restrictive and the construction process is c...
