Abstract
The utility model discloses a support device for excavation of a deep foundation pit of a piping trench of an urban main road. The support device comprises a support stress rack and a support bracing rack, wherein the support stress rack is composed of at least two pairs of splayed-structure side columns, top longitudinal supports and top horizontal supports positioned on the top of the side columns, and two layers of longitudinal supports and two layers of horizontal supports positioned in the center of the side columns, wherein a rectangle structure is formed by the top longitudinal support and the top horizontal support, and a rectangle structure is formed by the two layers of longitudinal supports and the two layers of horizontal supports; and the support bracing rack is composed of steel plates positioned at the left and right sides, the front and back sides and the top of the support stress rack; the support device comprises the support stress rack and the support bracing rack, wherein the support bracing rack bears soil pressure, and the soil pressure is transmitted to the support stress rack, so that temporary soil mass support can be provided, and workers can be protected reliably when entering the deep foundation pit; and all components in the support device are connected by bolts, so that the components can be repeatedly used in other foundation pits after being disassembled rapidly.
Description
Technical field
The utility model belongs to municipal engineering arterial street pipe trench deep pit construction technical field; Relate in particular to a kind of arterial street pipe trench deep pit digging suspension device; Be specially adapted to major urban arterial highway and be difficult to put the slope excavation and the little deep-foundation pit engineering of excavation width; This suspension device can carry out effective support to the foundation ditch of not putting sloping vertical cut, guarantees foundation ditch and constructor's safety.
Background technology
When carrying out tubing in the arterial street, because urban traffic conditions, can not take too many track, therefore can not put the slope construction normally, when foundation depth during greater than five meters, relevant specification of country is defined as deep foundation ditch.This type deep foundation ditch had both spent a large amount of expenses if adopt nonvolatil support pattern like piling, spray anchor etc., also can take the plenty of time simultaneously, delayed construction speed.
The utility model content
To the weak point of above-mentioned existence in the prior art, the utility model provides a kind of construction cost low, can improve the arterial street pipe trench deep pit digging suspension device of construction speed.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Arterial street pipe trench deep pit digging suspension device comprises that stressed of supporting and supporting go along with sb. to guard him frame; Two layers of longitudinal bracing and two layers of cross binding that stressed of said supporting is the side column of Eight characters structure, the top layer longitudinal bracing that is arranged on the side column top and top layer cross binding by at least two pairs and is arranged on the side column middle part are formed; Said top layer longitudinal bracing and top layer cross binding are formed rectangular configuration, and said two layers of longitudinal bracing and two layers of cross binding are formed rectangular configuration; Said supporting is gone along with sb. to guard him frame and is made up of the steel plate that is arranged on stressed left and right sides of supporting, both sides, front and back and top.
As a kind of preferred version of the utility model, said top layer longitudinal bracing, top layer cross binding, two layers of longitudinal bracing are connected through bolt with side column respectively with two layers of cross binding.
As the another kind of preferred version of the utility model, said steel plate point is welded in stressed of the supporting.
As another preferred version of the utility model, the top that said supporting is stressed is provided with at least two hangers.
Compared with prior art, the arterial street pipe trench deep pit digging suspension device of the utility model has following advantage:
1, this suspension device comprises that stressed of supporting and supporting go along with sb. to guard him frame, and supporting is gone along with sb. to guard him frame and born soil pressure, and power is passed in stressed of the supporting, thereby interim soil body supporting can be provided, and the personnel that make can access protection reliably when getting into the deep foundation ditch bottom.
2, adopt bolt to connect between each member in this suspension device, arrive other foundation ditches after can removing rapidly again and reuse.
Description of drawings
Fig. 1 is the structural representation of arterial street pipe trench deep pit digging suspension device.
In the accompanying drawing, 1-side column; 2-top layer longitudinal bracing; 3-top layer cross binding; 4-two layers of longitudinal bracing; 5-two layers of cross binding; 6-steel plate; 7-hanger.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
As shown in Figure 1, arterial street pipe trench deep pit digging suspension device comprises that stressed of supporting and supporting go along with sb. to guard him frame.Two layers of longitudinal bracing 4 and two layers of cross binding 5 (drawn among Fig. 1 two two layers of longitudinal bracings and four two layers of cross binding) that stressed of supporting is the side column 1 (four pairs of side columns that are Eight characters structure have drawn among Fig. 1) of Eight characters structure, the top layer longitudinal bracing 2 that is arranged on side column 1 top and top layer cross binding 3 (drawn among Fig. 1 two top layer longitudinal bracings and four top layer cross binding) by at least two pairs and is arranged on side column 1 middle part are formed.Top layer longitudinal bracing 2 is formed rectangular configuration with top layer cross binding 3, and two layers of longitudinal bracing 4 and two layers of cross binding 5 are formed rectangular configuration.Supporting is gone along with sb. to guard him frame and is made up of the steel plate 6 that is arranged on stressed left and right sides of supporting, both sides, front and back and top, and in the present embodiment, 6 of steel plates are welded in stressed of the supporting, and steel plate 6 has been formed the outer cover of a protection soil layer.
Top layer longitudinal bracing 2, top layer cross binding 3, two layers of longitudinal bracing 4 and two layers of cross binding 5 are connected through bolt with side column 1 respectively.Because stressed of supporting all adopts bolt to connect, and arrives other foundation ditches after this device can be removed rapidly again and uses.The top that supporting is stressed is provided with at least two hangers 7, in the present embodiment, on four angles, top of stressed of supporting, is equipped with hanger 7, is convenient to handling and installation.
This suspension device comprises that stressed of supporting and supporting go along with sb. to guard him frame, and supporting is gone along with sb. to guard him frame and born soil pressure, and power is passed in stressed of the supporting, thereby interim soil body supporting can be provided, and the personnel that make can access protection reliably when getting into the deep foundation ditch bottom.During use, this suspension device is assembled into as a whole outside construction area, hangs in the deep foundation ditch of accomplishing mechanical equivalent of light excavation by mobile crane, the constructor can get into the foundation ditch bottom and carries out the manual work end clearly, the quotations of going forward side by side political affairs piping erection then.After the completion to be installed, by mobile crane it is hung away, foundation ditch can carry out backfill.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of present technique scheme, it all should be encompassed in the middle of the claim scope of the utility model.
