Description
Technical field
The utility model belongs to the foundation pit construction technical field of construction work, is specifically related to a kind of foundation pit supporting construction.
Background technology
At present in the foundation pit construction of construction work, usually adopt cantilever supporting single pile.But when construction plant soil matrix is weak or cutting depth is large, or foundation ditch area very large time, adopt the bending rigidity of cantilever supporting single pile often can not meet the requirement of Deformation control, for this reason, have to add horizontal support, but arrange horizontal support again to construction period and cost influence very large.
Utility model content
The purpose of this utility model solves above-mentioned prior art Problems existing, there is provided a kind of bending rigidity high, be specially adapted to the occasion that construction plant soil matrix is weak or cutting depth is large or foundation ditch area is very large, and the Retaining Structure with Double-row Piles that construction technology is simple, cost is not high and the duration is shorter.
The technical scheme that the utility model is taked is as follows:
Retaining Structure with Double-row Piles, include front campshed, rear campshed, be connected to front campshed top front stake apical cap beam and be connected to rear campshed top rear stake apical cap beam, be connected to the coupling beam between front stake apical cap beam and rear stake apical cap beam, the soil mass consolidation between front campshed and rear campshed; Space gantry type supporting and protection structure is interconnected to form by front campshed, rear campshed, front stake apical cap beam, rear stake apical cap beam, soil mass consolidation, coupling beam.
When front campshed of the present utility model is identical with the height of rear campshed, described connector is be connected to connecting plate between front stake apical cap beam and rear stake apical cap beam or one group of parallel coupling beam.During height higher than front campshed of the height of rear campshed, described connector include to be arranged at inside rear campshed and with front stake apical cap Liangping row and contour supplementary contact beam, be connected to connecting plate between supplementary contact beam and front stake apical cap beam or one group of parallel coupling beam, be connected to raker beam between front stake apical cap beam and rear stake apical cap beam.Described front campshed and rear campshed are deposited reinforced concrete pile.Pile spacing between front campshed and rear campshed is 2 ~ 5 times of front campshed or rear campshed stake footpath.
When construction plant soil matrix is weak or cutting depth is large, or when foundation ditch area is very large, space of the present utility model gantry type supporting and protection structure is adopted to have following advantage: bending rigidity is high, the requirement of Deformation control can be met, and construction technology is simple, not with soil excavation cross-operation, the duration is short.Meanwhile, after inter-pile soil body is reinforced, be modified to homogeneous medium by approximate for inter-pile soil body, closer to the pseudoxanthoma elasticum theorem opinion in calculating, can not water-stop curtain be done again, relative saving construction cost.

Fig. 1 is the cross-sectional view of the first embodiment of the utility model;
Fig. 2 is the cross-sectional view of the utility model the second embodiment;
Fig. 3 is that the utility model connecting plate connects the schematic diagram of front stake apical cap beam and rear stake apical cap beam;
The schematic diagram of Fig. 4 to be the utility model by one group of parallel coupling beam connect front stake apical cap beam and rear stake apical cap beam.
Detailed description of the invention
Content of the present utility model is set forth further below in conjunction with Figure of description.
As shown in Figure 1, Retaining Structure with Double-row Piles described in the utility model includes front campshed 1, rear campshed 2, is connected to the front stake apical cap beam 3 on campshed top before whole row, after being connected to whole row campshed top rear stake apical cap beam 4, be connected to connector between front stake apical cap beam 3 and rear stake apical cap beam 4; Space gantry type supporting and protection structure is interconnected to form by front campshed 1, rear campshed 2, front stake apical cap beam 3, rear stake apical cap beam 4, coupling beam 7.It is soil mass consolidation 5 between front campshed and rear campshed.The height of front campshed 1 and rear campshed 2 can identical also can not be identical.When current campshed 1 is identical with the height of rear campshed 2, described connector is be connected to the monoblock connecting plate 6 between front stake apical cap beam 3 and rear stake apical cap beam 4, also can be to connect front stake apical cap beam 3 coupling beam 7 parallel with a group of rear stake apical cap beam 4.When current campshed 1 is not identical with the height of rear campshed 2, usually after, the height of campshed 2 is higher than the height of front campshed 1, now, described connector includes and to be arranged at inside rear campshed 2 and the supplementary contact beam 8 parallel and contour with front stake apical cap beam 3, to be connected to monoblock connecting plate 5 between supplementary contact beam 8 and front stake apical cap beam 3 or one group of parallel coupling beam 6, to be connected to raker beam 9 between front stake apical cap beam 3 and rear stake apical cap beam 4.Front campshed 1 and rear campshed 2 are deposited reinforced concrete pile.Pile spacing between front campshed and rear campshed is 2 ~ 5 times of front campshed or rear campshed stake footpath.
During construction, win in succession 6 or coupling beam 7 generally adopt cast-in-situ steel reinforced concrete to pour into a mould simultaneously, to guarantee its globality connected, bar splicing meets the requirement of Code for design of concrete structures.Soil mass consolidation 5 generally adopts the deep-mixed pile of prior art, high-pressure rotary jet grouting pile, slip casting or other method mix a certain amount of curing compound to soft foundation or make soil solidifying, to improve the mechanical property of foundation soil.Wherein deep-mixed pile, high-pressure rotary jet grouting pile two kinds of reinforcement means are all to be mixed as reinforcing raw material with curing compound (being generally cement) by undisturbed soil chemical reaction occurs, generate hydrate and firm mass of soil particle, again through solidifying hard and carbonation, the soil body of reinforcing is made to have the compacted soil pile body of globality, water stability and some strength.
The support form that the utility model adopts double-row pile to combine with the soil stabilization between double-row pile, after carrying out consolidation process to inter-pile soil, the transmission of power supposes relatively with theoretic spring, and practice of construction displacement reduces greatly.Carry out soil stabilization object to be physical and mechanical property in order to improve the soil body, to improve resistance of soil, modulus of compressibility, improve the intensity of soil and reduce the compressibilty of foundation soil, guarantee the globality of the soil body between double-row pile, especially under pile-anchor retaining implements limited condition, Retaining Structure with Double-row Piles, without the need to too large place, is a kind of recommendable foundation pit supporting construction form.Pour into front campshed, rear campshed, front stake apical cap beam, rear stake apical cap beam by steel concrete, win in succession or coupling beam and and soil mass consolidation between front campshed and rear campshed be connected to form space gantry type supporting structure system, greatly can increase support rigidity.
