Description
Technical Field
The utility model relates to a deep basal pit engineering pipeline suspends protection construction technical field in midair, concretely relates to suspension structure of deep basal pit engineering underground socket joint concrete pipe.
Background
In the municipal deep foundation pit engineering construction, the underground pipelines are complex, and the pipelines crossing the foundation pit are generally treated by an in-situ suspension protection method.
Because the socket joint concrete pipe is flexible joint, take place to warp easily and destroy and lead to the water logging foundation ditch, arouse the foundation ditch incident. At present, a common method is to convert a concrete pipe into a steel pipe by adopting a pipe jacking method and then suspend the steel pipe, and the method has high construction cost and great influence on the construction period.
Disclosure of Invention
In order to overcome the not enough of above-mentioned prior art, the utility model aims at providing a suspension structure of deep basal pit engineering underground socket joint concrete pipe does not need to replace the concrete pipe for the steel pipe. By adopting the cast-in-place reinforced concrete pipe hoop, the flexible joint of the socket concrete pipe is converted into the rigid joint and then suspended, and the concrete pipe has the characteristics of simple operation, safe use and cost saving. The utility model discloses the protection construction suspends in midair of all kinds of underground socket joint concrete pipe can be applicable to.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a suspension structure of deep basal pit engineering underground socket joint concrete pipe, includes the tight line knot, wraps up socket joint concrete coupling through reinforced concrete hoop, through the wire rope of pre-burying in reinforced concrete hoop, suspends socket joint concrete pipe in midair on the steel box girder of its top to tighten up wire rope through tight line knot, dop, accomplish and suspend the atress conversion in midair.
The suspension system for the underground socket concrete pipe of the deep foundation pit engineering is characterized in that the socket concrete pipe joint is wrapped by the reinforced concrete hoop, so that the flexible joint of the socket concrete pipe is converted into a rigid joint.
The reinforced concrete hoop is formed by pouring concrete into a steel reinforcement framework inside the reinforced concrete hoop, and the steel reinforcement framework comprises main reinforcements and longitudinal and horizontal distribution reinforcements which are arranged in the circumferential direction.
The utility model has the advantages that:
the utility model has the characteristics of easy operation, safe in utilization, saving cost compare with conventional system, only need handle the joint of socket joint concrete pipe, need not the process of push pipe conversion again, practiced thrift construction cost to easy operation is easy-to-use, and construction speed is fast. The method is suitable for suspension protection construction of various underground socket concrete pipes.

A construction method of a suspension structure of an underground socket concrete pipe of deep foundation pit engineering comprises the following steps:
the method comprises the following steps: excavating the earthwork of the foundation pit to the bottom of the underground socket pipe, excavating a groove at the joint of the underground socket concrete pipe 6, installing a circumferential main rib 7, a longitudinal horizontal distribution rib 8 and a template, pre-embedding a steel wire rope 3, and then pouring a reinforced concrete hoop 4;
step two: installing and erecting a steel box girder 5 on the foundation pit support structure 7;
step three: the steel wire rope 3 is hung to the steel box girder 5, and the steel wire rope 3 is tightened through the wire tightening buckle 1 and the chuck 2 to complete the stress conversion of the suspension of the socket concrete pipe 6;
step four: after the stress conversion is completed, digging out all soil below the socket concrete pipe 6;
step five: and a plurality of suspension structures between the foundation pit enclosing structures 7 form a suspension system.
