Abstract
The utility model relates to an environment friendly foundation pit support device and aims to provide an environment friendly foundation pit support device with the advantages of small occupied space, simple use, convenience in recycle and low cost. The environment friendly foundation support device comprises at least two support pillars and a plurality of grid bars; the support pillars are downwards inserted along the side wall of the foundation pit at intervals; multiple gird bars are arranged between two adjacent support pillars; two ends of the grid bars are respectively fixed on the two support pillars. The environment friendly foundation support device also comprises traction ropes; one ends of the traction ropes are fixedly connected onto the top ends of the support pillars; the other ends of the traction ropes are fixed in a soil layer at the backsides of the support pillars. Compared with the prior art, the environment friendly foundation support device has the advantages that the foundation pit support device does not need the concrete operation, the construction period is short, the support system can be synchronously completed along with the earth excavation of the foundation pit, foundation pit support materials can be recycled and used after the construction without influence on the environment and the environment friendly foundation support device has the characteristics of fast construction speed, low cost, environment friendliness and the like.
Description
Technical field
The utility model relates to a kind of environment-friendly type foundation pit support device.
Background technology
Along with modern architecture is increasing to the demand of the underground space, how safe, the economic supporting of carrying out pit earthwork, excavation become a hot issue.
Traditional method: adopt support patterns such as putting slope excavation, spray anchor and cement-soil-stirred pile, castinplace pile, limited by geographical environment but put slope excavation, cannot extensive use in city; The general construction periods of support pattern such as spray anchor, cement-soil-stirred pile, castinplace pile are longer, need after concrete reaches some strength, just can carry out soil excavation construction, and common engineering cost are also higher, not recyclable after construction, and environment is also had a certain impact.
Summary of the invention
The purpose of this utility model be to provide a kind of take up room little, use simple, be convenient to reclaim and the low a kind of environment-friendly type foundation pit support device of cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of environment-friendly type foundation pit support device, it comprises support column and the some grizzly bars of at least two, all support columns insert downwards along foundation pit side-wall interval successively, between two adjacent support columns, be provided with many grizzly bars, and the two ends of grizzly bar are separately fixed on two support columns.
It also comprises pull rope, and one end of pull rope is fixedly connected on the top of described support column, and the other end of pull rope is fixed in the soil layer of support column rear side.
Compared to prior art, the utility model has the advantage of: this foundation pit support device is without carrying out concrete work, short construction period, can synchronously improve support system with pit earthwork excavation, and pattern foundation pit supporting structure material is equal recoverable after construction completes, and environment, without impact, is had to speed of application fast, the features such as cost is low, environmental protection.
Brief description of the drawings
Fig. 1 is the structural front view of a kind of embodiment of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the right pseudosection of Fig. 1.
Label declaration: 1 support column; 2 grizzly bars; 3 pull ropes; 4 anchor studs; 5 foundation ditches; 6 soil layers.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
The embodiment schematic diagram of a kind of environment-friendly type foundation pit support device providing for the utility model as shown in Figure 1 to Figure 3, it comprises support column 1 and the some grizzly bars 2 of at least two, all support columns 1 insert downwards along foundation ditch 5 sidewall spacers successively, between two adjacent support columns 1, be provided with many grizzly bars 2, and the two ends of grizzly bar 2 are separately fixed on two support columns 1.
The cross section of described support column 1 is " work " font.The grooves on two sides of " work " font support column 1 is respectively used to the end of both sides grizzly bar 2 and inserts.
It also comprises pull rope 3, and one end of pull rope 3 is fixedly connected on the top of described support column 1, and the other end of pull rope 3 is fixed in the soil layer 6 of support column 1 rear side.
It also comprises the anchor studs 4 being arranged in support column 1 rear side soil layer 6, and one end that described pull rope 3 is positioned at support column 1 rear side is fixedly connected in anchor studs 4.
Described pull rope 3 is wire rope.
As shown in Figure 3, when construction, I-shaped support column 1 is driven underground along foundation ditch 5 limits by design pitch certain depth, as the main supporting support column 1 of foundation ditch 5 supportings, support column 1 injection is complete can start earth excavation, in soil excavation process, with soil excavation progress, in time by between adjacent snapping in of the grizzly bar of regular length 2 levels two support columns 1, prevent that the earthwork of foundation ditch 5 sidewalls from pouring in foundation ditch 5 inside, ensure the stable of the foundation ditch 5 sidewall soil bodys, realize the object of foundation ditch 5 supportings.The groove of " work " font support column 1 both sides guarantees that grizzly bar 2 two ends can not buried by soil layer, in excavation pit 5 processes, grizzly bar 2 can be slipped into easily downwards along support column.
In the time that cutting depth soil property situation dark or foundation ditch 5 sidewalls is poor, for the I-shaped support column that prevents cantilever force produces larger distortion toward foundation ditch 5 inside, can carry out the installation of auxiliary shoring system: the more stable local injection anchor studs 4 in foundation ditch 5 outsides, with wire rope by support column 1 drawknot in anchor studs 4, in a tensile stress to foundation ditch 5 outsides of the top of steel I-column construction, control the distortion of whole support system, ensure foundation ditch 5 construction safeties.
