Description
Technical field
The utility model relates to bracing of foundation pit field, relates in particular to a kind of oblique supporting pile structure for bracing of foundation pit.
Background technology
Foundation ditch must cause the distortion of surrounding soil in digging process, to around building and underground utilities exert an influence.Serious will jeopardize its normal use or safety, can increase support system stablize foundation ditch safety for fear of this situation in dark base design and hole construction, mainly contain at present three kinds of forms: support, diagonal brace and reverse anchoring.
Support and be widely used at present deep foundation ditch, taken space in a large amount of holes but support, long construction period, is unfavorable for digging, and when the later stage removes, potential safety hazard is large, has not only improved the cost of engineering but also be unfavorable for environmental protection.
Oppositely anchoring is the new technology of in recent years promoting, oppositely to be that foundation ditch is uncovered open for the advantage of anchoring, cut the earth and the little poor stability of the convenient but easy generation group's anchor effect safety factor of structure construction, the loaded down with trivial details cycle of construction technology is long, can not make full use of land resources because anchoring body exceeds land red-line.
Diagonal brace is used for the center rotary island formula construction of super-giant foundation pit, first excavate at foundation ditch center with respect to supporting to have more economic advantages but need in construction, after completing, construction of bottom plates just can carry out diagonal brace construction, and must reserve constuction joint in the time of building structure construction, the loaded down with trivial details long construction period of program, the later stage removes and structure difficult treatment.
The patent No. " 03267938.6 " discloses the diagonal brace that a kind of building foundation pit supporting is used, it comprises cant beam and cushion cap, it is characterized in that cushion cap is placed in the foundation ditch subsoil body of planning to build below basement bottom board, lower end and the cushion cap of cant beam are connected as a single entity, and upper end is connected with soil retaining block or is connected with the Guan Liang on soil retaining block top.This utility model adopts this kind of diagonal brace mode, with respect to supporting mode, have and cut the earth easily, can the disposable shoveling of large area, reduction of erection time, but excavate out cushion cap work plane in advance before cant beam construction time, need reserve the earthwork as the further construction of passive area stabilization, and the reserved earthwork needs very inconvenience of secondary excavation, the dismounting work of diagonal brace is also pretty troublesome, if do not removed, can not solve the problem of building structure sealing.
Along with area and the degree of depth of excavation of foundation pit are increasing, traditional support system has been difficult to meet the effect of safety economy, and the engineering quantity of traditional support form is large, and cost is high, and in support section excavation difficulty, the potential safety hazard existing in work progress is more, and the duration is longer.
Utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and provide a kind of oblique supporting pile structure for bracing of foundation pit, solve the technical problem that conventional pattern foundation pit supporting structure technique cost is high and construction is inconvenient, ensured safety and the economy of foundation pit construction.
The technical scheme in the invention for solving the above technical problem is: a kind of oblique supporting pile structure for bracing of foundation pit, comprise fender post, Guan Liang, base plate of foundation pit and building structure, also comprise oblique supporting pile, antipriming and reclamation structure, oblique supporting pile is at an angle in the oblique initial soil being implanted in below base plate of foundation pit; Oblique supporting pile top is fixedly connected with fender post top, is embedded in hat beam inside, forms overall structure with Guan Liang; Described oblique supporting pile bottom and bottom are fixed with reclamation structure around, and described reclamation structure is the hard solid structure that soil forms after overcuring is processed; Oblique supporting pile and building structure through part are provided with antipriming on oblique supporting pile, and described oblique supporting pile and base plate of foundation pit through part are also provided with antipriming on oblique supporting pile.
Antipriming, for the construction between oblique supporting pile and base plate of foundation pit through part and the construction between oblique supporting pile and building structure through part, after the construction later stage, oblique supporting pile cutting removed, prevents the seepy question of structure break joint; In Excavation Process, fender post is subject to the pressure of outside soil or works, and active force is sent to reclamation structure by oblique supporting pile, through overcuring reclamation structure after treatment, can effectively strengthen the supporting capacity of soil, the supporting role that improves oblique supporting pile.
As preferably, described oblique supporting pile is H formed steel construction, steel lattice column structure or steel tubular structure.
As preferably, described fender post uses Larsen steel sheet pile, reinforced concrete castinplace pile, the stake of SMW engineering method or steel pipe pile.
As preferably, the angle of the oblique insertion soil of described oblique supporting pile is less than 45 degree.
As preferably, described oblique supporting pile top is welded to connect or is connected by reinforcing bar binding by placing embedded iron parts with fender post top.
As preferably, described antipriming adopts sealing piece, and described sealing piece is connected with oblique supporting pile employing welding manner.
As preferably, reclamation structure is the hard solid structure forming after adopting high-pressure injection cement paste or soil-solidified-agent to process soil solidification.
The utility model compared with prior art, has the following advantages and beneficial effect: the construction period of 1, greatly having saved traditional support; 2, can realize accessible shoveling and structure construction; 3, do not need the construction materials such as a large amount of steel concrete, the later stage clears up without explosion, either environmental protection but also safety or reduced construction cost; 4, the sealing piece technology adopting is without the problem of considering constuction joint, and it is very convenient that later stage structure is processed; 5, thoroughly solve the stress release problem producing because of supporting removal; 6, thoroughly solve the potential safety hazard of the bracing of foundation pit suspended wall producing because of supporting removal.
