Abstract

The utility model discloses a supporting and protecting structure for inclined struts of a foundation pit. The supporting and protecting structure for the inclined struts of the foundation pit comprises a foundation pit and steel pipe piles arranged on the side face of the foundation pit, wherein a foundation pit base board which contains embedded bars is arranged in the foundation pit. The embedded bars are fixedly connected and combined with connecting blocks arranged on a base. At least two inclined holes are formed in the side face of the base at equal distance. Each inclined hole is in inserted connection with one end of each inclined strut. The other end of each inclined strut is fixedly combined with an enclosing purlin, and the enclosing purlins are fixedly combined with the steel pipe piles. According to the supporting and protecting structure for the inclined struts of the foundation pit, anti-shearing failure in the prior art can be avoided, construction process is simplified, project schedule is improved, and construction materials can be recycled.

Description

A kind of foundation ditch diagonal brace structure
Technical field
The utility model relates to a kind of foundation structure of building, especially relates to a kind of foundation ditch diagonal brace structure.
Background technology
The diagonal brace of building construction at present, subway station and tunnel foundation ditch inner support adopts monolithic reinforced concrete structure more, cast-in-situ steel reinforced concrete is because need the cast in situs maintenance, so the duration that needs is longer, and because the surrounding of thrust block reservation inclined hole will arrange the shearing resistance stiffener, increased working procedure and difficulty of construction, nonetheless shear failure also often easily occured.Owing to adopting reinforced concrete structure, thus recoverable not, and after basic engineering construction is completed, generally all adopt the mode of explosion when removing diagonal brace, and not only can bring environment pollution, also can produce a large amount of building castoffs.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of anti-shearing destruction of the prior art of avoiding is provided, and easy construction sequence improves programming, and a kind of foundation ditch diagonal brace structure of construction material recoverable.
The purpose of this utility model is achieved by following technical proposals: a kind of foundation ditch diagonal brace structure, comprise foundation ditch and the steel pipe pile that is arranged on the foundation ditch side, be provided with the base plate of foundation pit that contains embedded bar in described foundation ditch, the contiguous block that arranges on described embedded bar and base is fixedly connected, the side spaced set of described base has at least 2 inclined holes, one end of described inclined hole and diagonal brace plugs, the other end of described diagonal brace with enclose purlin concrete mutually, described purlin and the steel pipe pile concrete mutually of enclosing.
The diameter of described inclined hole is 2-4mm greater than the diagonal brace diameter.
The hole depth of described inclined hole is 200-300mm..
Spacing between described inclined hole is 500-600mm.
Described embedded bar is the 4-6 root, and the diameter of described reinforcing bar is 12-20mm.
The described purlin that encloses is that steel plate is made, and its sectional dimension is 200 * 200mm, and thickness is 18-20mm.
The beneficial effects of the utility model are: enclose between purlin and steel pipe pile can by be welded to connect, in the prefabricated inclined hole of the direct inserted base in bottom of diagonal brace, the top with enclose purlin can be by being welded to connect, base by between the contiguous block on base and base plate embedded bar by being welded to connect.The effect of steel pipe pile is opposing foundation pit side-wall soil pressure and water pressure, the effect of enclosing purlin is and the steel pipe close contact, and the horizontal pressure force that steel pipe is subject to is passed to diagonal brace, the effect of diagonal brace is that the horizontal pressure force with steel pipe passes to base, the effect of base is finally to bear the soil pressure of foundation pit side-wall and water pressure, the effect of base plate of foundation pit is the stability at the bottom of the assurance Foundation Pit, and at the bottom of contiguous block and plate, the effect of embedded bar is that base and base plate of foundation pit are firmly linked together.The utility model makes foundation ditch diagonal brace safety and reliability, can its support material of recycling, also can avoid and the environment pollution when reducing to remove.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is base cross-sectional structure schematic diagram in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 2 in Fig. 1: a kind of foundation ditch diagonal brace structure, comprise foundation ditch and the steel pipe pile 8 that is arranged on the foundation ditch side, be equipped with the base plate of foundation pit 2 that contains embedded bar 1 in described foundation ditch, the quantity of described embedded bar is set to the 4-6 root, and the diameter of its reinforcing bar is 12-20mm; The contiguous block 4 that arranges on the utility model embedded bar 1 and base 3 is fixedly connected, the side spaced set of described base 3 has at least 2 inclined holes 5, spacing between described 2 inclined holes 5 is set between 500-600mm, the utility model inclined hole 5 is used for plugging with an end of diagonal brace 6, for mutually coincideing of realizing pegging graft, the diameter that the diameter of described inclined hole 5 is greater than diagonal brace 6 is 2-4mm, and the hole depth of described inclined hole is preferably 200-300mm.; The other end of the utility model diagonal brace 6 with enclose purlin 7 concrete mutuallies, described purlin 7 and steel pipe pile 8 concrete mutuallies of enclosing, the utility model encloses purlin 7 to be made for steel plate, the sectional dimension of its steel plate is 200 * 200mm, thickness is 18-20mm.
Operating procedure of the present utility model is:
1 precast base is opened the reservation inclined hole on base, and contiguous block is welded on base;
2 will enclose purlin and steel pipe pile firm welding;
3 with the contiguous block on base and base plate embedded bar firm welding;
4 with in the inserted base preformed hole of diagonal brace bottom, the top with enclose purlin by being welded to connect.
