Abstract
The utility model discloses an oppositely pulled type filling pile base pit supporting structure. The oppositely pulled type filling pile base bit supporting structure comprises a supporting pile, a steel bar net and an anchor rod, wherein more than two anchor rod holes are distributed from the top down in the horizontal direction of the pile body of the supporting pile, and the anchor rod holes are all located on the same vertical plane; the two ends of the anchor rod are respectively connected with the supporting pile; and the steel bar net is fixed at the end of the anchor rod. The oppositely pulled type filling pile base pit supporting structure can be widely applied to the base pit supporting structures in the field of buildings, particularly to the base pit supporting structures in the geological relics, can effectively prevent collapse bodies at the side of base pits from collapsing and save a large amount of anchor rod materials, and is convenient for construction.
Description
Technical field
The utility model relates to a kind of the realm of building construction, is a kind of to pull-type poured pile base pit supporting construction specifically.
Background technology
At present all extensively adopt anchor to draw supporting and protection structure to carry out the protection of foundation ditch during to the both sides excavation pit of avalanche body at the realm of building construction; Both sides at the avalanche body are provided with soldier pile respectively; And respectively the anchor pole oblique cutting is gone into avalanche body inside; One end of anchor pole is fixedly connected with soldier pile, on termination point of anchor rod, is fixed with steel mesh reinforcement simultaneously, can on steel mesh reinforcement, spray during use and establish concrete.At the avalanche body during because of stressed collapsing; Then can be with on this force transmission to soldier pile and the steel mesh reinforcement; Then this firmly can further be passed on the termination point of anchor rod when this active force surpasses when bearing power on supporting and the steel mesh reinforcement; Termination point of anchor rod is postponed this active force to anchor pole again, the friction through anchor pole and avalanche body so that improve soldier pile and steel mesh reinforcement to the protective capacities of avalanche body.Its protection effect of this supporting and protection structure then will depend on the length and the quantity of anchor pole in former reason, and its friction that provides is also just big more more at most for the quantity of the longer or anchor pole of rock-bolt length, and then can make soldier pile and steel mesh reinforcement bear bigger pressure.Because it is oblique to inserting that anchor pole carries out bilateral; If employing increases rock-bolt length and improves its friction, in avalanche body central authorities the anchor pole intersection region can appear then, will certainly increase the anchor pole cost; If improve its friction and can produce crowd's anchor effect owing to spacing is too little with the mode that increases anchor pole quantity; To reduce the resistance to plucking ability of anchor pole and increase displacement, be unfavorable for protection, have serious potential safety hazard the avalanche body.And these 2 kinds of modes all can increase engineering quantity, and then increase construction costs, are unfavorable for creating conservation-minded society.
Summary of the invention
In order to solve the deficiency of prior art structure, it is a kind of to pull-type poured pile base pit supporting construction that the utility model provides, and to reach the saving cost, avoids group generation of anchor effect, improves the purpose to the protective capacities of avalanche body.
The utility model is realized through following technical proposals: in the supporting and protection structure of being made up of soldier pile, steel mesh reinforcement and anchor pole; On the pile body of soldier pile, be provided with bolthole; The two ends of anchor pole are passed bolthole respectively and are connected with castinplace pile, and on termination point of anchor rod, are fixedly connected with steel mesh reinforcement, all horizontal distribution of bolthole on every soldier pile; Its quantity is at least 2, and bolthole all is positioned on the same vertical plane.During use; With the both sides of soldier pile vertical distribution, and an end of anchor pole passed from the bolthole on soldier pile wherein, and from the bolthole of another root soldier pile of same horizontal level, pass at the avalanche body; With nut the anchor pole two ends are pinned then; Simultaneously steel mesh reinforcement is fixed on the termination at anchor pole two ends, forms an integral body between anchor pole, soldier pile, steel mesh reinforcement and the avalanche body, can prevent that like this avalanche body from collapsing.
The beneficial effect of the utility model is: not only the avalanche body is had very strong protective action, can be widely used in and need carry out in the construction field of two-sided protection, and product structure is simple, can practice thrift a large amount of construction costs, easy construction is convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the three-dimensional structure diagram of the utility model.
Fig. 2 implements state plan structure sketch map for the utility model.
Fig. 3 implements the state cross-sectional view for the utility model.
Code description among the figure: 1,1 ' soldier pile; 2 anchor poles; 3 nuts; 4 steel mesh reinforcements; 5 avalanche bodies; 6,6 ' soldier pile; 7 steel mesh reinforcements; 8 nuts; 9 boltholes.
The specific embodiment
As shown in Figure 1; The utility model is made up of soldier pile (1) (1 ') (6) (6 '), anchor pole (2), nut (3) and steel mesh reinforcement (4) (7); On soldier pile, be equipped with bolthole (9); And wherein the horizontal level of the last bolthole of soldier pile (1) (1 ') is all corresponding, and the horizontal level of the last bolthole of soldier pile (6) (6 ') is all corresponding.In use like Fig. 2, shown in Figure 3; Soldier pile (1) (1 ') (6) (6 ') is separately positioned on the both sides of avalanche body (5); On the pairing avalanche body of bolthole, hole, then anchor pole (2) is pierced into from the bolthole on the soldier pile (1), and the bolthole from soldier pile (1 ') passes; Use nut (3) (8) that anchor pole is pinned respectively at the two ends of anchor pole; Respectively steel mesh reinforcement (4) (7) is fixed on the termination point of anchor rod simultaneously, order is carried out the concrete spraying operation on steel mesh reinforcement then, makes steel mesh reinforcement form one protection slab.After adopting the utility model to fix; Avalanche body and supporting and protection structure form an integral body; The avalanche body either party receive active force all can through its supporting and protection structure with this force transmission to the whole avalanche body; Thereby reach the purpose that prevents that effectively the avalanche body from collapsing, realize good protection foundation ditch.
Need to prove, be equipped with 3 boltholes on the soldier pile in the utility model, but can increase according to the degree of depth of foundation ditch or reduce in actual use, but should keep 2 boltholes at least.Though the quantity of soldier pile is 4 groups in enforcement as shown in Figure 2, can increase and reduce according to actual conditions equally, but it be fit to form close set to keep 2 groups of soldier piles (promptly 4) at least.
Because anchor pole directly is fixedly connected with the soldier pile of both sides in the utility model; Thereby the length of anchor pole has effectively been shortened; Significantly reduce simultaneously the usage quantity of anchor pole, practiced thrift cost, given full play to the resistance to tension of single anchor pole; Reduce the distortion of one-sided anchor structure, be more conducive to environmental protection.
Claims (2)
1. one kind to pull-type poured pile base pit supporting construction; Form by soldier pile, steel mesh reinforcement and anchor pole; It is characterized in that: on the pile body of soldier pile, be provided with bolthole, the two ends of anchor pole are passed bolthole respectively and are connected with castinplace pile, and on termination point of anchor rod, are fixedly connected with steel mesh reinforcement.
2. according to claim 1 to pull-type poured pile base pit supporting construction, it is characterized in that: all horizontal distribution of bolthole on every soldier pile, its quantity is at least 2, and bolthole is positioned on the same vertical plane.
