The height of body is 0.5~0.75 meter；It is known that this height is preferably, the height that can also be arranged as required to the two is
Other height, as long as ensureing that support, installation, dismounting and recycling are convenient.
The embodiment of the present invention is specifically described in further detail below.
The embodiment of the present invention provides the assembly recovery type prestressing force branch protecting assembly for underground shaft, can be used in underground shaft
As the supporting of the borehole wall, such as by taking shield cutter inspection-pit as an example, the branch protecting assembly is using steps are as follows：
Step 1) is after the completion of the well head collar tie beam of inspection-pit pours, assembled steel ring beam and well head guardrail.Then carry out the earthwork
First steel waist rail (i.e. assembling type steel waist rail, for convenience of description then be referred to as steel waist rail) is set up after excavation, (such as with connector
Bolt) waist rail and steel ring beam are attached, steel waist rail is strutted and is put in place by preload piece, with bolt by connector and steel waist
Beam bolts, and the connection of steel waist rail and steel ring beam is fastened with bolt.
After step 2) sets up first of steel waist rail, the soil body is excavated, per Pin cutting depth 0.5m, sets up one layer of corrugated plating in time
(i.e. pin-connected panel corrugated plating, for convenience of description, after be referred to as corrugated plating), after it is connect with first of steel waist rail, with preload
Part struts, and is fastenedly connected corrugated plating with connector, and corrugated plating and first of steel waist rail are bolted.
Second steel waist rail is connect by step 3) with connector with corrugated plating, and preload piece struts steel waist rail and is put in place,
Connector and steel waist rail are bolted with bolt, and steel waist rail and corrugated plating fastening are bolted.
The subsequent work progress of step 4) repeats step 2), step 3), step 4), up to branch protecting assembly supporting to shaft bottom.
Step 5) is laid with back cover steel plate, and the multiple shaped steel of close paving on back cover steel plate again in shaft bottom, by multiple shaped steel both ends with
Bottom one of steel waist rail is bolted connection.
It should be noted in above structure assembly Bracing Process：It (1), (can at interval of a distance according to formation condition
To be 1.5m, 2m or other distances) primary behind filler material is noted behind in corrugated plating；(2) per 3m longitudinal connecting member of connection.
It is convenient in corrugated plating back-grouting using corrugated plating in branch protecting assembly of the present invention, such as may be used every 1.5m or
2m injects a macromolecule polymer material behind in corrugated plating, to fill corrugated plating behind gap.The four of monocycle corrugated plating
It is each on a ripple plate to reserve an injected hole, or in such a way that scene is punched.
The branch protecting assembly of the present invention, convenient that supporting is carried out to the borehole wall of underground shaft with assembly method, convenient, energy when use
Simplify the construction process of underground shaft, lifting construction speed, and after the completion of constructing, this branch protecting assembly is recycled and followed after facilitating dismounting
Ring reuses, which combines prestressing force support technology and backfill the mode of intumescent material behind, effectively inhibits soil
Body deforms, and reduces surface subsidence.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art is in the technical scope of present disclosure, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
