The invention provides a pile-anchor support structure without waist beams for rapid treatment of landslides and a construction method thereof. The pile-anchor support structure without waist beams for rapid treatment of the landslides comprises a structure to connect support piles through anchor cables and special-shaped anchors. The cumbersome construction problem that in an existing pile-anchorsupport method without waist beam frameworks, a tension bearing structure is used to lock steel strands on a support pile is solved. The requirement of construction of cumbersome waist beams in an existing pile-anchor support structure is avoided, support without waist beams is achieved, and the construction period is shortened. The construction method of the pile-anchor support structure withoutwaist beams for rapid treatment of the landslides comprises the steps that firstly, adjacent halved anchor cable steel strands are penetrated into first cable holes and second cable holes of the special-shaped anchors respectively, P anchor heads are installed at the exposed ends of the cable head faces, then locking anchor cable steel strands are penetrated into the cable holes and taper holes of the special-shaped anchors, and locking plates tension the locking anchor cable steel strands to a designed prestress value. The anchors greatly simplify the construction of the pile-anchor supportstructure without waist beams.
Description
Technical field [0001] The invention relates to a non-waist-beam pile-anchor supporting structure and a construction method thereof for quickly treating landslides, belonging to the technical field of building construction. technical background [0002] Anchor support technology is widely used in foundation pit support, slope support and other projects. Its main components are supporting piles, waist beams and anchor cables. The way of force transmission is that the soil pushes the supporting pile to deform, and the supporting pile is propped against the waist beam, which drives the waist beam to pull out the anchor cable. The anchor cable relies on the bond between grouting body and rock and soil to provide pullout resistance, thus maintaining the safety and stability of the whole supporting system. [0003] The waist beam of anchor support is the main transmission component, and the commonly used waist beams are reinforced concrete waist beam and steel waist beam. However, the ...
