Embodiment Construction

[0019] Such as figure 1 As shown, a prestressed anchor cable pile-slab wall described in the embodiment of the present invention includes a supporting wall 1, and at least two transversely arranged waist beams 2 are arranged on the supporting wall 1, and each waist A plurality of anchor cables 3 of diagonal braces are installed on the beam 2, each anchor cable 3 passes through the supporting wall and the end section of the anchor cable is fixed in the soil layer on the rear side of the supporting wall 1, and the anchor cables The head of 3 is fixed on the waist beam 2, and the top of the supporting wall 1 is provided with a top beam 4, and the anchor cable 3 extends obliquely downward.

[0020] The anchor cable 3 is a tensile anchor cable, including a free section 31 and an anchor section 32, the free section 31 is embedded in the soil layer at the front section and can slide freely, and the anchor section 32 is implanted at the end section and anchored to the in the soil lay...

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 [0001] The invention relates to a prestressed anchor cable pile slab wall, which belongs to the technical field of concrete support construction applied to foundation pits and slopes. Background technique [0002] At present, deep foundation pits and high slopes are supported by internal supports, pile retaining walls, anchors, spray anchors, etc. The cost of internal supports is high and the construction speed is slow, and the combination of pile retaining walls and pile retaining walls and anchors cannot Supporting requirements, the construction of prestressed anchor cables is difficult especially in soft strata. Under the premise of ensuring safety, most of the same foundation pit or slope support adopts internal support or other methods, which are expensive and slow in construction speed. Contents of the invention [0003] In order to solve the problem that the slab wall is relatively difficult in the soft ground environment, the present invention prov...
