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
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 being applied to foundation ditch and slope place.
Background technology
At present, deep foundation ditch, high slope rockmass have employing inner support, stake barricade, anchor pole, spray anchor etc., inner support cost is high, speed of application slow, and stake barricade and the combination of stake barricade anchor pole do not reach supporting requirement, and construction prestressed cable particularly has its difficulty at broken ground.Same foundation ditch or slope retaining, under guarantee secured premise, mostly adopt inner support, or other method, and cost is high, and speed of application is also slow.
Summary of the invention
In order to solve broken ground environment in, the larger problem of board wall difficulty, the invention provides a kind of Prestressed Anchor Cable Poling Board Wall.
