The utility model discloses can overcome the restriction in external space, have to have the better effect of strutting, and construction convenience, process are simple, whole supporting construction is reasonable, firm.
Description
Technical field
The utility model relates to building operations Retaining Structure with Double-row Piles technical field.
Background technology
In recent years, along with the quickening of urban construction, City Building is more and more intensive, and land resources is more and more nervous, and geological conditions worse and worse, much plans to build building and seizes every opportunity, and often builds very nearby at distance existing building, city turnpike road.Forbid due to a lot of area or limit the soil used beyond building line, so while making full use of soil, bringing following problems to building foundation pit smooth construction:
(1) because the building planned to build is very near from existing building, city turnpike road distance, cause can not adopting when building foundation pit is constructed and put slope and excavate, and soil-nail wall support, pile-anchor retaining can not be used;
(2) adopt campshed to add the support pattern of inner support, although technical scheme is feasible, execute that cost is higher, operation is numerous and diverse, the construction period is longer, to soil excavation and main structure body construction infection comparatively serious;
(3) although traditional Double-row-piles Structure good integrity, anti-side rigidity is large, has certain restriction, be difficult to meet design requirement to displacement; The cantilever segment limited length of cantilevered Retaining Structure with Double-row Piles, and supporting safety factor is lower, and slope deforming is larger.
For the problems referred to above, need to find a kind of restriction that can overcome free surrounding space, there is again good supporting effect and easy construction and the simple New Supporting pattern of operation.
Summary of the invention
The utility model object solves above-mentioned prior art Problems existing, a kind of Retaining Structure with Double-row Piles with lateral connection component is provided, to solve the restriction being subject to free surrounding space in urban architecture pattern foundation pit supporting structure, make pattern foundation pit supporting structure difficulty, weak effect, technical difficulty and high in cost of production problem.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Retaining Structure with Double-row Piles with lateral connection component, include before building foundation pit place campshed, rear campshed in the outer good ground of foundation ditch, be connected to before tie-beam between the stake top of campshed and the stake top of rear campshed, be horizontally through the lateral connection component of front campshed and rear campshed two piles arranged side by side between two respectively, front campshed, rear campshed, tie-beam, lateral connection Component composition become Retaining Structure with Double-row Piles.
Tie-beam described in the utility model is the monolithic construction beam of on-the-spot continuous pouring.Described lateral connection component is reinforced concrete member or steel strand or anchor cable, and the front-end and back-end of lateral connection component are separately fixed on front campshed and rear campshed.Described front campshed, rear campshed are square or circular stake reinforced concrete pile, and front campshed and rear campshed are embedded with horizontal sleeve pipe, and front campshed, through horizontal sleeve pipe, is connected with rear campshed by lateral connection component.
The utility model relies on the lateral connection component arranged between front campshed, rear campshed, can significantly reduce taking of the underground space, is applicable to the existing building that is close to and important traffic route around.Lateral connection component also effectively increases the factor of safety against overturning of double-row pile, and suitably can reduce the building-in depth of front campshed and the pile body length of rear campshed, reduces construction cost, shortens the construction period.Adopt the utility model, can make to form tensile stress between front campshed and rear campshed, improve the pile body force-bearing situation of total, optimize the whole supporting and protection structure of double-row pile, make whole supporting and protection structure become more reasonable, firm.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the schematic diagram that lateral connection component connects front campshed and rear campshed.
Detailed description of the invention
Followingly by reference to the accompanying drawings the technical solution of the utility model to be described in detail.
The Retaining Structure with Double-row Piles with lateral connection component as shown in Figure 1, mainly comprise before building foundation pit 7 place campshed 1, rear campshed 2 in the outer good ground 5 of foundation ditch, be connected to before tie-beam 3 between the stake top of campshed and the stake top of rear campshed, be horizontally through the lateral connection component 4 of front campshed 1 and rear campshed 2 adjacent two piles arranged side by side between two respectively, front campshed 1, rear campshed 2, tie-beam 3, lateral connection component 4 have been combined into Retaining Structure with Double-row Piles.Tie-beam 3 of the present utility model adopts cast-in-site mode, is the monolithic construction beam that continuous pouring is shaping.Lateral connection component 4 can adopt reinforced concrete member, also can adopt steel strand, or adopts anchor cable, and the front-end and back-end of lateral connection component 4 are separately fixed at front campshed 1 with on rear campshed 2.Front campshed 1, rear campshed 2 are square bar rib concrete pile or circular stake reinforced concrete pile.According to designing requirement, when the inside reinforcing cage of the front campshed of making and rear campshed, i.e. pre-buried horizontal sleeve pipe 6.When carrying out Retaining Structure with Double-row Piles construction, by boring, the horizontal sleeve pipe in front campshed and the horizontal sleeve pipe in rear campshed are connected, between often adjacent two piles (a front campshed and after campshed) by one or more pre-buried sleeve pipe 6 through one or more lateral connection component 4, by lateral connection component 4 by front campshed 1 and rear campshed 2 by being connected.
The utility model is mainly used in the restriction being subject to free surrounding space in urban architecture pattern foundation pit supporting structure, with the construction of existing building, the very near occasion of city turnpike road distance.
The utility model is in work progress, and construction sequence is as follows:
The first step: according to designing requirement, carries out surveying setting-out, determines front campshed, rear campshed position;
Second step: in the front campshed determined, the boring of rear campshed position;
3rd step: the reinforcing cage making front campshed, rear campshed, and on reinforcing cage, press the pre-buried horizontal sleeve pipe of design attitude, the quantity of horizontal sleeve pipe is determined according to design;
4th step: the construction carrying out front campshed, rear campshed and stake top continuous beam;
5th step: excavation pit, when constructing to the horizontal sleeve pipe position of front campshed, aims at front-seat pipe casing and rear campshed sleeve pipe is holed, make front-seat pipe casing and rear campshed sleeve pipe through;
6th step: by lateral connection component through front-seat pipe casing and rear campshed sleeve pipe, and two ends joint location is reinforced;
One deck under last excavation pit, arranges lateral connection component as also needed, repeat step 5, step 6.
