Description
Technical field
The utility model belongs to building foundation pit supporting systems technology field, is specifically related to a kind of masts type Double-row Piles Support system.
Background technology
Along with developing rapidly of the novel urbanization planning construction of country, deep foundation ditch has become important component part that is high-rise and super highrise building, and its support engineering has also become the important subitem of construction engineering.Common building foundation pit supporting pattern has undisturbed soil to put the combination of the supporting types such as slope, plate brad supporting, bolt-spary supports, pile-anchor retaining, joist anchor supporting, the supporting of campshed cantilever, steel sheet pile supporting, diaphragm wall and support supporting and wherein two kinds and two or more supporting type, and the pattern foundation pit supporting structure of current most object of construction production adopts above-mentioned supporting type.
Because city building density is more and more higher, congested in traffic, narrow field, geological conditions washability is poor.In order to make full use of soil, the new building deep big foundation pit supporting type of contiguous existing building is restricted.Obviously traditional slope of putting cannot be adopted to excavate, plate brad supporting and bolt-spary supports method can not be carried out again.Take traditional stake (wall) anchor supporting, because neighbour builds the restriction of underground structure and pipeline, soil body limited width behind slope, so anchor cable angle is comparatively large, supporting effect is not good, the anchor cable and some side slopes cannot be constructed at all.Diaphragm wall adds and supports the method for supporting, as interim soil-baffling structure comparatively other method costly, special geological conditions or construction method improper, easily occur that adjacent wall section can not be alignd and leak water problem, the process of waste mud is cumbersome.
" overhang mill pattern " is not with inner support, anchor pole (rope), the soil pressure that the drag entirely provided by the part embedded in the soil body applies to balance foundation pit side-wall supporting and protection structure.Usually, when foundation depth is little, to can yet be regarded as a kind of supporting and protection structure type preferably from aspect analyses such as cost, construction period, construction technologies.But displacement is remarkable by the impact of insert depth, can not meet the requirement of complicated deep big foundation pit engineering stability and controlling distortion aspect.
Utility model content
Large in order to solve above-mentioned " cantilever supporting structure pattern " displacement at pile top, the problem being not suitable for deep big foundation pit is affected by insert depth, the utility model is in order to improve stress performance and the deformation characteristic of Cantilever Retaining, excavate the potential of supporting pile body, supporting and protection structure form is made more to be tending towards rationally reliable, meet the requirement that complicated deep big foundation pit props up the gear soil body, fully utilize the limited underground space, traditional double-row pile gantry type frame construction pattern is improved, remove linking beam or whole plate, propose a kind of masts type Double-row Piles Support system.
In order to solve the problem, the utility model is achieved by following technical scheme:
Masts type Double-row Piles Support system described in the utility model, comprise front-seat soldier pile, rear row's soldier pile, described front-seat soldier pile is connected by the first capping beam, described rear row's soldier pile is connected by the second capping beam, described front-seat soldier pile and ground maintain an equal level, described rear row's soldier pile elevates above the soil, and forms Suo Zhu; Be provided with at least one prestress anchorage cable between described Suo Zhu and described front-seat soldier pile, described prestress anchorage cable and described Suo Zhu form the angle being less than 90 degree.
Further, in order to provide support power for front-seat soldier pile better, the height of described Suo Zhu is greater than the trestle column of described front-seat soldier pile and rear row's soldier pile.
Further, in order to increase the stability of structure, the degree of depth that described rear row's soldier pile embeds front-seat soldier pile embedding soil described in native depth ratio is dark.
Further, the two ends of described prestress anchorage cable are anchored respectively at described front-seat soldier pile and Suo Zhushang.
Further, the layout of described front-seat soldier pile and described rear row's soldier pile is that rectangular array is arranged or T-shaped formula is arranged, limit is arcuately arranged, quincunx is arranged, two trigonometric expression is arranged.
Compared with prior art, the beneficial effects of the utility model are:
The utility model increases the bending rigidity of cantilever supporting structure, and during excavation of foundation pit, front campshed plays a part to share soil pressure, and then campshed has been held concurrently and propped up gear and draw anchor double action.
Comparatively linking beam cost is low for anchor cable of the present utility model, and effectively improves the stability of Double-row-piles Structure, increases its resistance to capsizing.
The utility model makes full use of pile soil common action, plays the self-bearing capacity of the soil body between two campsheds, changes soil body lateral pressure distribution, strengthens supporting effect.
The utility model is applicable to multiple foundation condition, from weak soil to hard stratum, closely knit sandy gravel stratum, various soft or hard rocks etc. can be applied, ground limited within can making full use of building line and space, play returns of investment.
The utility model is high, quality controllable without inner support, convenient construction, work efficiency, have good economic benefit, and anchor cable can be recycled, cost-saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the schematic diagram of masts type Double-row Piles Support system described in the utility model;
