TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, concretely relates to a novel supporting structure. BACKGROUND

[0002] In foundation pit construction, the stress of supporting pile is large, and the stress of supporting pile is unbalanced on the two sides of inside and outside of foundation pit, specifically, the supporting pile will be subjected to the pressure of outside soil body, leading to the displacement of supporting pile to the direction of foundation pit, influencing the stability of foundation pit and causing the security risk. SUMMARY

[0003] The utility model relates to a novel supporting structure, through burying reinforcing pile on the side of supporting pile far from foundation pit, and connecting the two through draw together spare, give the tension of supporting pile to the direction of the side far from foundation pit, to balance the pressure of outside soil body of supporting pile to the direction of foundation pit.

[0004] The utility model relates to a novel supporting structure for enclosing foundation pit, comprising: a plurality of supporting piles enclosed in the peripheral edge of foundation pit; a plurality of reinforcing piles buried in the outside soil body of foundation pit, the number of a plurality of reinforcing piles and a plurality of supporting piles is same and position one-to-one correspondence; a plurality of draw together spare are used for fixing connection in each pair of reinforcing pile and supporting pile one-to-one correspondence, and the draw together spare is buried in the outside soil body.

[0005] The utility model further improves that still include: the counterweight fixed on the side of supporting pile far from foundation pit and used for balancing the horizontal stress of supporting pile.

[0006] The utility model further improves that the counterweight is concrete pavement, and the concrete pavement is fixed on the top end of supporting pile and extends to the side far from foundation pit.

[0007] The utility model further improves that the supporting pile is Larsen steel sheet pile.

[0008] The utility model further improves that the draw together spare is steel strand, and the both ends of steel strand are fixed on reinforcing pile and supporting pile respectively.

[0009] The utility model further improves that the reinforcing pile is I-steel.

[0010] The utility model further improves that the supporting pile is Larsen steel sheet pile. BRIEF DESCRIPTION OF DRAWINGS

[0013] In the figure: 1, support pile; 2, reinforcing pile; 3, tie member; 4, counterweight; 5, foundation pit. DETAILED DESCRIPTION

[0014] As Figures 1-2 shown, a novel support structure includes a plurality of support piles 1 surrounding the inner peripheral edge of the foundation pit 5; a plurality of reinforcing piles 2 buried in the outer side soil of the foundation pit 5, the number of the plurality of reinforcing piles 2 is the same as that of the plurality of support piles 1 and one-to-one corresponding; a plurality of tie members 3 for one-to-one fixedly connected between each pair of reinforcing piles 2 and support piles 1, the tie member 3 is buried in the outer side soil.

[0015] As Figure 1 shown, it further includes a counterweight 4 fixed to the side of the support pile 1 away from the foundation pit 5 and used for balancing the horizontal force of the support pile 1, by fixedly connecting the counterweight on the support pile 1, the force given to the side of the support pile 1 away from the foundation pit 5 can be balanced, so as to balance the stress of the support pile 1. As Figure 1 shown, the counterweight 4 is a concrete pavement, the concrete pavement is fixed to the top end of the support pile 1 and extends to the side away from the foundation pit 5, by taking the concrete pavement as the counterweight 4, the construction of the counterweight can be completed at the same time when the pavement is constructed, without additional construction of the counterweight, which is convenient for construction and saves cost.

[0016] Preferably, as Figure 1 shown, the support pile 1 can select to adopt the Larson steel sheet pile.

[0017] Preferably, as Figure 1 shown, the tie member 3 is a steel strand, the two ends of the steel strand are respectively fixed to the reinforcing pile 2 and the support pile 1, by setting the steel strand and connecting the steel strand with the reinforcing pile 2, the steel strand actively provides the pulling force of the support pile 1 to the foundation pit 5.

[0018] Preferably, as Figure 1 shown, the reinforcing pile 2 in the embodiment adopts an I-beam, the I-beam is more common, has low cost and good stress performance.

[0019] It should be explained finally: above only is the preferred embodiment of the utility model and is not used for limiting the utility model, although the utility model has been explained in detail with reference to foregoing embodiment, for the skilled person in the art, it still can modify the technical scheme recorded in foregoing each embodiment or make equivalent replacement to part technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model should be contained in the protection scope of the utility model.
