The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
In part of cement soil agitation pile inside or the outside be inserted with the preformed pile of steel concrete, preformed pile interval in cement mixing method distributes.
See figure referring to Fig. 1 foundation pit enclosure structure, the cement mixing method 1 formed for the cement-soil mixing pile machine construction around foundation ditch, cement mixing method 1 in a row forms Soil-cement Wall, mutually overlaps between cement mixing method or does not overlap.Inside or outside at cement mixing method are inserted with precast reinforced concrete piles.Precast reinforced concrete piles inserts in the cement-soil stirring pile construction process, all inserts precast reinforced concrete piles or only in the cement mixing method of part, insert precast reinforced concrete piles in each cement mixing method.
Referring to Fig. 2, described preformed pile cross section is rectangle.Rectangular pile is solid or hollow reinforced concrete pile.Perhaps described rectangular pile preformed pile is square pipe pile.Insert the bearing capacity that this preformed pile has strengthened cement mixing method.
Referring to Fig. 3, described preformed pile cross section is inverted T-shaped.The stake of inverted T-shaped Prefabricated Concrete can be used for one-sided (edge of a wing side is arranged), and to bear moment of flexure larger, and opposite side (without edge of a wing side) is subject to curved less situation.Owing to can more reinforcing bar being set in edge of a wing side, therefore can bear larger flexural tensile stress; And opposite side is stressed less, configure less reinforcing bar and can meet force request, because arrangement of reinforcement is less, breadth of section can reduce, so this side can not arrange the edge of a wing.This cross section can be equipped with material with stressed size and combine closely, and has both met the bearing capacity instructions for use, has saved again constructional materials.
Referring to Fig. 4, the convex shape that described preformed pile cross section is the flat wing.Insert the bearing capacity that this preformed pile has strengthened cement mixing method.
Referring to Fig. 5, described preformed pile cross section is I-shaped.I-shaped Prefabricated Concrete stake can be used for the situation that larger moment of flexure is all born in strong axle both sides.Because the both sides at web all are provided with the edge of a wing, can configure more reinforcing bar, larger internal force all can be born in the both sides of fender post.This cross section also can be designed to by two side wing edges the cross section that width, thickness do not wait according to the difference of the stressed size in both sides, and material configuration and stressed size are coincide mutually, avoids waste of material.
Referring to Fig. 6, what described preformed pile cross section was the flat wing is I-shaped.Insert the bearing capacity that this preformed pile has strengthened cement mixing method.
Referring to Fig. 7, described preformed pile cross section is L shaped.Insert the bearing capacity that this preformed pile has strengthened cement mixing method.
Referring to Fig. 8, described preformed pile cross section is concavees lens shape.This cross section can be used for bending and shearing and all is subject to curved all larger situations in the large and strong axle of pile body both sides.Because there is not obvious web in this cross section, lifting surface area is larger, can be equipped with more reinforcing bar, can resist larger moment of flexure, also can resist larger shearing.
Referring to Fig. 9, described preformed pile cross section is four limit concave shaped.Insert the bearing capacity that this preformed pile has strengthened cement mixing method.
When adopting stiffening pile to carry out supporting, be provided with the multilayer waist rail on the inboard cement mixing method in a row of foundation ditch, waist rail is connected with under oblique the stiffening pile that stretches into the foundation ditch outside.
When adopting the inner support supporting, be provided with fish belly shape prestressing force and enclose purlin on the inboard cement mixing method in a row of foundation ditch, fish belly shape prestressing force encloses purlin and comprises a lower-cord beam of being close to the foundation ditch inboard, be provided with web member on lower-cord beam, web member stretches to the foundation ditch inboard, the web member top is provided with steel strand, and the two ends of steel strand are connected with the two ends of lower-cord beam, and steel strand and lower-cord beam form the structure of a closure.
The another kind of foundation pit supporting construction with the deformed bar concrete precast pile, comprise cement mixing method in a row, and cement mixing method inside or the outside are inserted with the concrete preformed pile of deformed bar; Be provided with Guan Liang or waist rail on preformed pile, Guan Liang or waist rail are connected with under oblique the stiffening pile that stretches into the foundation ditch outside, and described stiffening pile is to be inserted with reinforcing body in mixing jet-grouting forms.In all cement mixing method inside or the outside preformed pile that is inserted with steel concrete.In part of cement soil agitation pile inside or the outside be inserted with the preformed pile of steel concrete, preformed pile interval in cement mixing method distributes.
The deformed bar concrete precast pile is with embodiment 1.
