Abstract
The invention discloses a pre-stressed anchor cable slab-pile wall which comprises at least two middle beams, a capping beam and a plurality of cast-in-place piles which are arranged side by side. The middle beams are installed on the cast-in-place piles, the capping beam is erected on the tops of the cast-in-place piles, a plurality of anchor cables are arranged on each middle beam, the anchor cables extend downwards in an inclined mode, the head portions of the anchor cables are fixed on the middle beams, the tail portions of the anchor cables are fixed in a soil layer on the rear side of the cast-in-place piles, a certain distance is kept between every two adjacent cast-in-place piles, and each anchor cable penetrates through two cast-in-place piles. According to the pre-stressed anchor cable slab-pile wall, the slab wall formed by cement-mixed piles can ensure foundation pit safety within 6m in a sludge layer and ensure foundation pit or side slope safety within 12m in the soil layer or soft rock; the slab wall formed by the cast-in-place piles can ensure foundation pit safety with 9m in the sludge layer and ensure foundation pit or side slope safety within 12m in the soil layer or soft rock.
Description
Technical field
The present invention relates to a kind of Prestressed Anchor Cable Poling Board Wall, belong to technical field of construction under the concrete ground that is applied to foundation ditch and place, slope.
Background technology
At present, deep foundation ditch, high slope supporting have adopts interior support, stake barricade, anchor pole, spray anchor etc., in support the cost height, speed of application is slow, stake barricade and the combination of a stake barricade anchor pole do not reach the supporting requirement, construction prestressed cable particularly has its difficulty at broken ground.Same foundation ditch or slope retaining are guaranteeing under the safe prerequisite, support in mostly adopting, or other method, cost height, speed of application are also slow.
Summary of the invention
For solve the broken ground environment in, the big problem of board wall difficulty the invention provides a kind of Prestressed Anchor Cable Poling Board Wall.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of Prestressed Anchor Cable Poling Board Wall comprises that at least two waist rails, capping beam and several are the castinplace pile that is arranged side by side, and described waist rail is installed on the described castinplace pile, and described capping beam is erected at the top of castinplace pile; Be provided with several anchor cables at each described waist rail, described anchor cable is tilted to down extension, and its head is fixed on the waist rail, and its latter end is fixed in the soil layer of castinplace pile rear side, maintain a certain distance between adjacent two castinplace piles, each anchor cable passes between two castinplace piles.
The downward-sloping angle of described anchor cable is the arbitrary value between the 0-45 degree.
Preferably, the distance between adjacent two castinplace piles is no more than 50cm;
Further, the distance between adjacent two castinplace piles is no more than 40cm;
Further, the distance between adjacent two castinplace piles is no more than 30cm;
Further, the distance between adjacent two castinplace piles is no more than 20cm;
Further, the distance between adjacent two castinplace piles is no more than 10cm.
Preferably, between adjacent two castinplace piles, arrange net, and spray concrete on the net; Perhaps do not arrange net, directly between adjacent two castinplace piles, spray concrete.
Described anchor cable is the tension type anchor cable, comprises free section and anchoring section, and described free section is arranged in leading portion implantation soil layer and can be free to slide, and described anchoring section is arranged in latter end and implants and be anchored in soil layer.
Described anchor cable is the pressure-type anchor cable, and namely total length is free section, does not do anchoring section.
Described waist rail is i beam or other steel work section bar or reinforced concrete beam.
Prestressed Anchor Cable Poling Board Wall of the present invention, the board wall that adopts cement mixing pile to constitute can guarantee 6m with interior foundation ditch safety on the mud stratum, soil layer or soft rock can guarantee that 12m is with interior foundation ditch or side slope safety; The board wall that adopts castinplace pile to constitute can guarantee 9m with interior foundation ditch safety on the mud stratum, soil layer or soft rock can guarantee that 12m is with interior foundation ditch or side slope safety.
