Abstract
A steel-pipe pile and anchor bar combined foundation pit supporting member comprises a row of equi-spaced steel-pipe piles along the edge of the foundation pit, wherein, the steel-pipe pile consists of at least one traverse steel bar connected with each other to form a framework, one end of the anchor bar is fixed on the framework, and the other end of the anchor bar is downwards and slantways anchored into the soil horizon of the side slope of the foundation pit. With good concertedness of structure, simple required equipment, low construction costs, no pollution, low noise and good emergency effect, the utility model has a supporting fee two thirds of that of the general supporting fee, therefore, the utility model is suitable for the supporting of foundation pit, side slope, dam and neighbouring buildings as well as applicable to the rapid supporting of collapsing foundation pit and checking dam rescue.
Description
The utility model relates to a kind of building unit, particularly a kind of member that is used for pattern foundation pit supporting structure.
In recent years, along with highrise building is increasing, the existence of basement causes building foundation pit to need supporting to handle, and traditional method is single campshed, campshed is at interval closeer, has that the construction works amount is big, more to site requirements, a support engineering cost height, shortcoming such as long in time limit.
The purpose of this utility model provides a kind of steel pipe pile and adds combining anchor pattern foundation pit supporting structure member, reduces the support engineering cost, shortens the construction period, improves the supporting safe effect.
The technical solution of the utility model: this steel pipe pile adds combining anchor pattern foundation pit supporting structure member, comprise the steel pipe pile of uniformly-spaced implanting around the foundation ditch edge in a row, it is characterized in that: steel pipe pile is fixedly connected into frame body by at least one Cross slat steel, anchor pole one end is fixed on the frame body, and the other end is downward-sloping to be anchored in the excavation slope soil layer.
Above-mentioned Cross slat steel is channel-section steel or the angle steel that is welded on the steel pipe pile.
Above-mentionedly anchor into anchor pole in the excavation slope soil layer and the angle of inclination of horizontal plane is 8-35 °.
Above-mentioned anchor pole one end is fixed on the horizontal steel bar of frame body or on the steel pipe pile.
Preparation method of the present utility model: in the supporting of excavation slope adjacent building, earlier steel pipe pile is passed through the rig pore-forming to certain depth, steel pipe pile is put into the hole, adopt impact method that steel pipe pile is squeezed into projected depth, when steel pipe pile is put into the hole, outside the hole, put into C
10Plain concrete, in impact process, plain concrete forms one along managing outer filling up with steel pipe pile under the Guan Zhi.In the excavation of foundation pit certain depth, squeeze into anchor pole by designing requirement, anchor pole is arranged on the channel-section steel of laterally putting, and in particular cases, anchor pole also can be welded on the steel pipe pile, and channel-section steel is welded on the steel pipe pile.So just form steel pipe pile and anchor pole collaborative work, played the pattern foundation pit supporting structure member of support action.
The advantage that the utility model and comparing of prior art have: it is the support system member that acts between a steel pipe campshed and the anchor pole, and the structure concertedness is good, and equipment needed thereby is simple, and it is fast to bore speed of application with 30 type rigs and automobile, shortens the construction period; Construction costs is cheap, only is general supporting expense 2/3; Improve the supporting safe effect, pollution-free, noise is low.Be applicable to the supporting of pattern foundation pit supporting structure, slope retaining, dykes and dams supporting, adjacent structure, very near to adjacent structure especially, supporting effect is greatly remarkable, also is applicable to foundation ditch landslide and the flood control dykes and dams quick supporting of speedily carrying out rescue work, and has fine emergent supporting effect.
Below in conjunction with drawings and Examples of the present utility model the utility model is described in detail:
Fig. 1 is a plane arrangement structure schematic diagram of the present utility model;
Fig. 2 is the side view of anchor pole position;
Fig. 3 is frame body structural representation figure.
Embodiment: as Figure 1-3, when making 50 meters pattern foundation pit supporting structures, be washed into the hole, uniformly-spaced implant a row or multi-row steel pipe pile 1 by pile spacing 0.5-1.5 rice, steel pipe pile stake footpath Φ 127-173mm around foundation ditch 4 edges with 30 type rig automobiles brill; Length is decided according to calculating; Steel pipe pile fixedly is welded into frame body by the transverse channel steels 2 of the 1.5 meters spacings in three roads, and anchor pole 3 one ends are fixed on the transverse channel steels, and the other end is downward-sloping to be anchored in the foundation ditch 4 side slope soil layers.The angle of inclination of anchor pole and horizontal plane is 10-15 ° and is the best; Anchor pole is 1.0-2.0 rice at interval, aperture Φ 130mm.
Claims (4)
