Abstract
The invention provides a cross beam foundation pit supporting structure. According to the cross beam foundation pit supporting structure, a plurality of groups of connecting beams arranged horizontally are used for fixedly connecting supporting piles of two sides of the side wall of a foundation pit into a supporting whole, rib columns are arranged behind the connecting beams, the length of each rib column is smaller than that of each supporting pile, and the width of each rib column is smaller than the diameter of each supporting pile. The cross beam foundation pit supporting structure can disperse pushing force applied on the rib columns into the cross beam foundation pit supporting structure formed by the rib columns, the connecting beams and the supporting piles, fully utilizes the supporting piles of the two sides of the side wall of the foundation pit to serve as fixing members, improves supporting effect of the supporting structure, prevents soil bodies of the side wall of the foundation pit from collapsing, ensures safety of the foundation pit, reduces use amount of anchor cables, and saves engineering cost at the same time.
Description
Technical field
The present invention 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
At present be widely used soldier pile as the supporting and protection structure of foundation ditch in building engineering construction, it mainly is comprised of many soldier piles, and all be reserved with a plurality of anchor cable holes on every soldier pile, be provided with anchor cable in anchor cable hole, and be 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 design stake position around foundation ditch, be reserved with anchor cable hole on soldier pile, carry out subsequently the soil mass of foundation pit excavation, and carry out steel mesh reinforcement and lay and anchor cable construction in digging process, steel mesh reinforcement carries out the concrete spray 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 in this class supporting and protection structure is all stressed separately, 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 larger on soil body impact under 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 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 increase the use amount of anchor cable, also extended 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 invention 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 has reduced the impact on foundation ditch bottom solum geologic structure, and has reduced the use amount of anchor cable.
The present invention realizes by following technical proposals: the both sides at foundation pit side-wall are provided with soldier pile, be provided with anchor cable on soldier pile, and be provided with tie-beam between soldier pile, 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 be 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 supporting pile length, and the width of rib post is less than the diameter of soldier pile.In the present invention, 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 subject on 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 invention has the beneficial effects as follows: 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 reduce use amount and the engineering construction amount of anchor cable under the prerequisite that does not reduce foundation ditch integer support effect, thereby saved engineering cost, accelerating construction progress, simultaneously also can shorten the length of rib post fixed section, avoid the soil layer geologic structure generation harmful effect to the foundation ditch bottom, guaranteed engineering safety, the novel construction of this practicality is very easy, and supporting effect is remarkable, be convenient to promote the use of.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.

Fig. 2 is plan structure schematic diagram of the present invention.
Code description in 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 respectively the both sides of foundation pit side-wall, and with many group tie-beams (2), soldier pile is fixedly connected as a supporting integral body, and each tie-beam all is and is horizontally disposed with, and be provided with rib post (3) in foundation pit side-wall (6) soil body of next-door neighbour's tie-beam rear side, 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 present invention is when implementing, first soldier pile is arranged on the predetermined position of foundation pit side-wall both sides, be reserved with anchor cable hole on soldier pile, carry out subsequently the excavation of foundation pit operation, and synchronously carry out the rib post and construct in digging process, carry out the tie-beam construction when being excavated to suitable height, the horizontal setting of tie-beam also is fixedly 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 middle rib post of the present invention, therefore guaranteeing to shorten respectively the length of rib post and the width of rib post under the constant condition of supporting effect, make the length of rib post less than the supporting pile length, 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 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 the rib post in the situation that do not use anchor cable still to have stronger support capacity, simultaneously also can further reduce 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, guarantee foundation ditch safety.
