Abstract
The utility model discloses a #-shaped-beam foundation pit bracing structure, which is characterized in that a plurality of groups of horizontally arranged connecting beams are used for fixedly connecting bracing piles arranged at two sides of a side wall of a foundation pit into a bracing whole, meanwhile, the back of the connecting beams is provided with rib columns, moreover the length of each rib column is smaller than the length of each bracing pile, and the width of the rib column is smaller than the diameter of each bracing pile. With the adoption of the bracing structure, push force stressed on the rib columns can be dispersed in the #-shaped bracing structure formed by the rib columns, connecting beams and the bracing piles; the bracing piles arranged on two sides of the side wall of the foundation pit are used as fixing members, so the bracing effect of the bracing structure is improved, a soil body at the side wall of the foundation pit is prevented from collapsing, the foundation pit is enabled to be safe, meanwhile, the usage amount of anchor cables is reduced, and accordingly, the project cost is reduced.
Description
Technical field
The utility model relates to a kind of building engineering construction field foundation pit supporting construction, is a kind of nine-squares beam foundation pit supporting construction specifically.
Background technology
In building engineering construction, be extensive use of soldier pile at present as the supporting and protection structure of foundation ditch, it mainly is made up of many soldier piles, and all be reserved with a plurality of anchor cables hole on the every soldier pile, anchor cable is provided with anchor cable in the hole, and is fixedly connected with steel mesh reinforcement between soldier pile.Soldier pile for boring cast-in-place, in be provided with cage of reinforcement.During use, soldier pile is arranged on the foundation ditch design stake position on every side, be reserved with the anchor cable hole on the soldier pile, carry out the soil mass of foundation pit excavation subsequently, and in digging process, carry out steel mesh reinforcement and lay and anchor cable construction, steel mesh reinforcement carries out the concrete spraying operation after laying again, collapses with the soil layer that prevents foundation pit side-wall, anchor cable can strengthen the supporting effect of soldier pile, prevents that soldier pile from toppling because of stressed the generation.Because each soldier pile is all stressed separately in this class supporting and protection structure, therefore in order to promote supporting effect, the pile body of each soldier pile is all longer, and be provided with to organize anchor cables more, the fixed section of soldier pile is also darker, thereby bigger to soil body influence under the foundation ditch, original geologic structure on destructible stratum, reduce the resistance of the foundation ditch bottom soil body, be unfavorable for foundation ditch safety.And in order to prevent that the soil body between soldier pile from collapsing, the spacing in the supporting and protection structure between each soldier pile is generally less, has increased engineering quantity and engineering cost.Because every soldier pile all needs to carry out anchor cable construction, thereby has increased the use amount of anchor cable, also prolonged the engineering construction cycle when increasing construction costs.
Summary of the invention
In order to solve the deficiency of existing foundation pit supporting construction, the utility model provides a kind of nine-squares beam foundation pit supporting construction, this nine-squares beam foundation pit supporting construction not only has stronger support action to foundation pit side-wall, and reduced influence to foundation ditch bottom solum geologic structure, and reduced the use amount of anchor cable.
The utility model is realized by following technical proposals: the both sides at foundation pit side-wall are provided with soldier pile, be provided with anchor cable at soldier pile, and between soldier pile, be provided with tie-beam, and be provided with the rib post at the rear of tie-beam simultaneously, wherein tie-beam is from top to bottom and is horizontally disposed with, and fixedly connected with soldier pile, the rib post structure that is square is the square crossing setting with tie-beam, and next-door neighbour's tie-beam, and the length of rib post is less than the length of soldier pile, and the width of rib post is less than the diameter of soldier pile.In the utility model, the common groined type supporting and protection structure that forms an integral body of tie-beam, soldier pile and rib post, its middle rib post and tie-beam can be passed to the soil body thrust that is subjected on the soldier pile, because soldier pile has stronger stability after anchor cable is fixing, thereby can improve the supporting effect of supporting and protection structure.
The beneficial effects of the utility model are: not only can play effective support action to foundation pit side-wall, and because rib post and continuous beam can take full advantage of the soldier pile of foundation pit side-wall both sides as anchorage element, make tie-beam, the common groined type supporting and protection structure that forms an integral body of soldier pile and rib post, can under the prerequisite that does not reduce the whole supporting effect of foundation ditch, reduce use amount and the engineering construction amount of anchor cable, thereby saved engineering cost, accelerating construction progress, also can shorten simultaneously the length of rib post fixed section, avoid the soil layer geologic structure of foundation ditch bottom is produced harmful effect, guaranteed engineering safety, the novel construction of this practicality is very easy, and supporting effect is remarkable, 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 main TV structure schematic diagram of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Code description among the figure: 1,1 '-soldier pile; The 2-tie-beam; 3-rib post; The 4-anchor cable; 5-foundation ditch bottom; The 6-foundation pit side-wall.
The specific embodiment
As shown in Figure 1 and Figure 2, soldier pile (1,1 ') is located at the both sides of foundation pit side-wall respectively, and with how group tie-beams (2) are fixedly connected as a supporting integral body with soldier pile, and each tie-beam all is and is horizontally disposed with, and in foundation pit side-wall (6) soil body of next-door neighbour's tie-beam rear side, be provided with rib post (3), rib post and tie-beam are the square crossing setting, and next-door neighbour's tie-beam, and the infall at soldier pile and tie-beam is provided with anchor cable (4) simultaneously.The utility model is when implementing, earlier soldier pile is arranged on the predetermined position of foundation pit side-wall both sides, be reserved with the anchor cable hole on the soldier pile, carry out the excavation of foundation pit operation subsequently, and in digging process, carry out the rib post synchronously and construct, carry out tie-beam construction when being excavated to suitable height, the horizontal setting of tie-beam is also fixedlyed connected with soldier pile, and its middle rib post is arranged in the soil body of tie-beam rear side foundation pit side-wall.Because can effectively utilizing tie-beam and soldier pile to carry out pressure, disperses on the utility model middle rib post, therefore guaranteeing to shorten the length of rib post and the width of rib post under the constant condition of supporting effect respectively, make the length of rib post less than the length of soldier pile, the width of rib post is less than the diameter of soldier pile.Because the soldier pile of foundation pit side-wall both sides is fixed by tie-beam and anchor cable; thereby has stronger stability; be positioned at the middle rib post of soldier pile and then can take full advantage of the soldier pile of both sides as anchorage element; the thrust that it is suffered is effectively disperseed; thereby can guarantee that the rib post still has stronger support capacity under the situation of not using anchor cable; also can further reduce simultaneously the length of diameter and the fixed section thereof of rib post; this has just reduced engineering cost to a certain extent; also accelerated construction speed; and the minimizing of rib post fixed section length has also been avoided the geologic structure of foundation ditch bottom (5) is produced harmful effect, guarantees foundation ditch safety.
