Description
Technical field
The utility model relates to building structure construction field, particularly relates to a kind of recyclable pattern foundation pit supporting structure anchor cable structure.
Background technology
Anchorage Technology is widely used in the supporting of the engineerings such as coal road road, metallurgy, water conservancy and hydropower, Rail Highway, military project and building, and it utilizes anchor cable that anchored force is provided, and the soil pressure of opposing periphery reaches the firm of the excavation rear perimeter edge soil body.In urban construction municipal engineering, anchoring in pattern foundation pit supporting structure is normally provisional, after supporting task finishes, its effect is also just lost, if do not reclaimed, may produce infringement disputes, and cause waste of material, also can form a large amount of urban underground construction rubbish and obstruction, the development and utilization of the Underground Space Resource that impact day rear perimeter edge is non-renewable simultaneously.
Utility model content
For addressing the above problem, the utility model provides a kind of recyclable pattern foundation pit supporting structure anchor cable structure.
The utility model solves the technical scheme that its technical problem adopts:
A kind of recyclable pattern foundation pit supporting structure anchor cable structure, comprise some prestressing force dowels that are set in parallel in cement mortar, the upper one end in cement mortar bottom of each prestressing force dowel is equipped with definite value anchor head, the termination of prestressing force dowel is also provided with the anchor slab being all fixedly connected with each prestressing force dowel, is also provided with some isolating frames that are all fixedly connected with each prestressing force dowel between two anchor slabs.
Be further used as the improvement of technical solutions of the utility model, each prestressing force dowel includes some terminations and is fixed on the presstressed reinforcing steel in definite value anchor head.
Be further used as the improvement of technical solutions of the utility model, the one end of stretching out cement mortar on each prestressing force dowel is provided with the anchorage head that is positioned at each prestressing force dowel of anchor slab outside locking.
Be further used as the improvement of technical solutions of the utility model, definite value anchor head is the cylindrical-shaped structure of top sealing and inner hollow, and definite value anchor head is fixed by extruding and each prestressing force dowel termination.
The beneficial effects of the utility model: this recyclable pattern foundation pit supporting structure anchor cable structure fixedly carries out pattern foundation pit supporting structure by definite value anchor head by the termination of each prestressing force dowel, extruding force between each prestressing force dowel and definite value anchor head is decided by the length of definite value anchor head and the gap situation between definite value anchor head inner side and prestressing force dowel, after foundation pit supporting construction has been constructed, fixing between dismounting definite value anchor head and prestressing force dowel, can realize the recovery of supporting anchorage cable, thereby prevent the underground space to produce and pollute.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment prestressing force dowel structural representation;
Fig. 3 is the utility model embodiment definite value anchor head position cross sectional representation.
The specific embodiment
With reference to Fig. 1～Fig. 3, the utility model is a kind of recyclable pattern foundation pit supporting structure anchor cable structure, comprise some prestressing force dowels 1 that are set in parallel in cement mortar, the one end that is positioned at cement mortar bottom on each prestressing force dowel 1 is equipped with definite value anchor head 2, the termination of prestressing force dowel 1 is also provided with 3 of anchor slab 3, two anchor slabs that are all fixedly connected with each prestressing force dowel 1 and is also provided with some isolating frames 4 that are all fixedly connected with each prestressing force dowel 1.
This recyclable pattern foundation pit supporting structure anchor cable structure fixedly carries out pattern foundation pit supporting structure by definite value anchor head 2 by the termination of each prestressing force dowel 1, the extruding force that each prestressing force dowel 1 and definite value anchor head are 2 is decided by the gap situation of 1 of the length of definite value anchor head 2 and definite value anchor head 2 inner sides and prestressing force dowel, after foundation pit supporting construction has been constructed, dismantle the fixing of 1 of definite value anchor head 2 and prestressing force dowel, can realize the recovery of supporting anchorage cable, thereby prevent the underground space to produce and pollute.
As the utility model preferred embodiment, each prestressing force dowel 1 includes some terminations and is fixed on the presstressed reinforcing steel 11 in definite value anchor head 2.
Definite value anchor head 2 pushes each presstressed reinforcing steel 11 by metallic sheath and is fixed, the bond stress of definite value anchor head 2 and each presstressed reinforcing steel 11 equal each presstressed reinforcing steel 11 ultimate compressive strength 75%, the design anchored force of each prestressing force dowel 1 is definite value anchor head 2 and 80% of the bond stress of each presstressed reinforcing steel 11.When prestressing force dowel 1 completes after supporting task, utilize pulling force that the presstressed reinforcing steel in prestressing force dowel 11 is pulled out from definite value anchor head 2, complete the recovery of prestressing force dowel.
The one end of as the utility model preferred embodiment, stretching out cement mortar on each prestressing force dowel 1 is provided with and is positioned at the lock anchorage head 5 of each prestressing force dowel 1 of anchor slab 3 outsides.
As the utility model preferred embodiment, definite value anchor head 2 is the cylindrical-shaped structure of top sealing and inner hollow, and definite value anchor head 2 is fixed by extruding and each prestressing force dowel 1 termination.
This structure is used non-bending steel cable as the presstressed reinforcing steel 11 of pattern foundation pit supporting structure, design anchored force according to anchoring support to the requirement of prestressing force dowel 1 anchored force and single presstressed reinforcing steel 11, calculate the quantity of presstressed reinforcing steel 11 in anchor cable, in this utility model structure, preferably the quantity of presstressed reinforcing steel 11 is seven.
After prestressing force dowel 1 supporting task completes, with punching jack, by root, steel strand are pulled out from definite value anchor head 2, then use hoist engine or Lever Blocks to reclaim presstressed reinforcing steel 11.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
