Abstract
The utility model discloses a supporting pile body with waterproof curtains around a foundation pit. The supporting pile body solves the technical problems that in the prior art, the construction operation face is large, and the construction costs are high. The supporting pile body comprises the foundation pit (1), the sealed cement waterproof curtains (2) are arranged on the side faces of the periphery of the foundation pit (1), reinforced concrete supporting piles (3) are arranged on the outer sides of the sealed cement waterproof curtains (2) at intervals, the reinforced concrete supporting piles (3) are meshed with the sealed cement waterproof curtains (2), and when the reinforced concrete supporting piles (3) and the sealed cement waterproof curtains (2) are meshed, the largest meshing thickness is 250 mm. The supporting pile body is simple in construction process and low in construction cost and ensures the safety of the surrounding building.
Description
Technical field
The utility model relates to a kind of soldier pile, particularly the supporting pile body of a kind of foundation ditch sealing and soldier pile interlock.
Background technology
Along with social development and the progress of urban construction, due to the growing tension of building land, impel building to develop to high-altitude.Build highrise building and generally all be unable to do without deep pit digging.Also more and more less in the old construction operation space of adjoining between inhering architecture and new proposed building, in limited operating distance, carry out pattern foundation pit supporting structure, reach the sealing of foundation ditch and guarantee the safety of foundation ditch, become difficult point and the emphasis of foundation pit supporting project.For the sealing requirement of excavation of foundation pit, the following two kinds of construction methods of the general employing of prior art.The first is carried out reinforced concrete pile supporting and cement-soil curtain water stop; It two is to utilize steel sheet pile self support characteristic to carry out pile body to improve to carry out sealing.Above-mentioned two kinds of methods have certain limitation, and the first construction technology is simple, easy to operate, cheap, but constructing operation face is large; The second applicability is wide, and safety factor is high, but construction costs is high.
Summary of the invention
The utility model provides a kind of supporting pile body of foundation ditch surrounding band water-stop curtain, solved the large and high technical problem of construction costs of constructing operation face that prior art exists.
The utility model is to solve by the following technical programs above technical problem:
A kind of supporting pile body of foundation ditch surrounding band water-stop curtain, comprise foundation ditch, be provided with the cement-soil water-stop curtain of sealing in the surrounding side of foundation ditch, compartment of terrain, outside at cement-soil water-stop curtain is provided with steel concrete soldier pile, steel concrete soldier pile and cement-soil water-stop curtain are interlocked, and the maximum interlock thickness that steel concrete soldier pile and cement-soil water-stop curtain are interlocked is 250 millimeters.
Be provided with and pass through beam on the top of steel concrete soldier pile.
The pile body that a kind of sealing that the utility model provides is combined with supporting, is particularly suitable for the construction operation difficult problem for the working space of inadequate 1.75 meters of next-door neighbour surrounding building operating space; Construction technology is simple, and construction costs is low, has ensured the safety of surrounding building.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation in cross section of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of supporting pile body of foundation ditch surrounding band water-stop curtain, comprise foundation ditch 1, be provided with the cement-soil water-stop curtain 2 of sealing in the surrounding side of foundation ditch 1, compartment of terrain, outside at cement-soil water-stop curtain 2 is provided with steel concrete soldier pile 3, steel concrete soldier pile 3 is interlocked with cement-soil water-stop curtain 2, and steel concrete soldier pile 3 is 250 millimeters with the maximum interlock thickness 4 that cement-soil water-stop curtain 2 is interlocked.
Be provided with and pass through beam 5 on the top of steel concrete soldier pile 3.
The utility model has changed the usual practice of former construction, cement-soil water-stop curtain and reinforced concrete pile supporting position have been carried out to evolution, and carry out anti-stake mechanics check computation, and supporting scheme checking computations and demonstration, check the technical data of cement-soil water-stop curtain and reinforced concrete pile, and the relation of definite foundation ditch sideline and cement-soil water-stop curtain and the position of cement-soil water-stop curtain and reinforced concrete pile.Carry out the construction of cement-soil water-stop curtain, to cement-soil water-stop curtain unwrapping wire, draw control point, stake position outward at cement-soil water-stop curtain, utilize cement-soil water-stop curtain control point to draw control point, reinforced concrete pile stake position, reduce the accumulation of error, guarantee cement-soil water-stop curtain construction axis and structural drawings axial line distance, error is controlled at carries out operation in 10 millimeters; When cement-soil water-stop curtain starts to construct, the test cube in the same condition that utilizes cement-soil water-stop curtain self material to make by professional is differentiated the cement-soil water-stop curtain initial setting time, utilize the actual test cube in the same condition of job site and laboratory provide cement-soil water-stop curtain material just, the report of final setting time, control activity duration of reinforced concrete pile.In reinforced concrete pile operation, strictly control the size of interlock between cement-soil water-stop curtain and reinforced concrete pile, carry out steel concrete pile driving construction.
The utility model is to carry out anti-pile driving construction in 6 hours that have constructed to cement initial set by cement water-stop curtain, utilize cement water-stop curtain self material to carry out mud off, in cement water-stop curtain, adopt the boring of percussive drill retaining wall, reinforcing cage is winched in boring with crane, and carry out concrete building by conduit, in shortening water-stop curtain, the setting time interval of cement and anti-pile concrete, finally makes the stake of steel concrete poured support and the complete interlock of cement water-stop curtain stake.
Claims (2)
