Abstract

The invention discloses a pre-stress anchor cable pile-slab wall which comprises a supporting wall, at least two walings arranged transversely are arranged on the supporting wall, a plurality of diagonal bracing anchor cables are installed on each waling, each anchor cable penetrates through the supporting wall, moreover, the tail end of each anchor cable is fixed in an soil layer on the rear side of the supporting wall, and the heads of the anchor cables are fixed on the walings. A capping beam is arranged at the top of the supporting wall, and the anchor cables extend downward obliquely. According to the pre-stress anchor cable pile-slab wall, if cement-mixed piles are adopted for the slab wall, safety of a foundation ditch within 6m in a sludge stratum can be ensured, and the safety of the foundation ditch or a side slope within 12m in the soil layer or a soft rock layer can be ensured. if cast-in-place piles are adopted for the slab wall, the safety of the foundation ditch within 9m in the sludge stratum can be ensured, and the safety of the foundation ditch or the side slope within 12m in the soil layer or the soft rock layer can be ensured.

Description

Prestressed Anchor Cable Poling Board Wall
Technical field
The present invention relates to a kind of Prestressed Anchor Cable Poling Board Wall, belong to the concrete support technical field of construction 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, comprise the supporting body of wall, be provided with the waist rail of at least two lateral arrangement at the supporting body of wall, the anchor cable of several diagonal braces is installed at each waist rail, each anchor cable passes described supporting body of wall and the latter end of anchor cable is fixed in the soil layer of supporting body of wall rear side, the head of anchor cable is fixed on the waist rail, is provided with capping beam at the top of described supporting body of wall, and described anchor cable is tilted to down extension.
Preferably, described supporting body of wall is formed by the overlapping overlap joint of several cement mixing piles, and is provided with the castinplace pile of a plurality of dispersed placement in the outside of several described cement mixing piles; Described capping beam is erected at the top of described castinplace pile.Described anchor cable passes described cement mixing pile and is fixed on the waist rail.
Perhaps selectable, described supporting body of wall is spliced to form by several cement boards, is provided with a castinplace pile at the seam crossing of adjacent two cement boards; Described capping beam is erected at the top of described castinplace pile.Described anchor cable passes described cement board and is fixed on the waist rail.
The inclination angle of described anchor cable is the arbitrary value between the 0-45 degree.
Further selectable, 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.
Perhaps, 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.
