Abstract

The invention relates to a construction method of a holding and pressing type static-pressure driven cast-in-place pile by adopting a holding and pressing type static-pressure immersed tube pile machine. The machine comprises a machine body, a pile hanging mechanism, a walking mechanism, a control device and a side holding type pile clamping and pressing mechanism, wherein the side holding type pile clamping and pressing mechanism is connected with a pile clamping box sliding up and down along a slide rail through a pile pressing oil cylinder by a pile pressing frame, a pile clamping oil cylinder is arranged in the pile clamping box and connected with a clamping block for clamping a pile tube, and the pile clamping box is elastically connected with a concrete jolt ramming mechanism. The construction method comprises the following steps of: immersing the pile tube to an underground designed elevation part in a holding and pressing mode from the side face of the pile tube; primarily pouring concrete to an elevation part at the bottom of a reinforcing steel bar cage; then putting the reinforcing steel bars into a pile tube hole; and pouring concrete to the top of the reinforcing steel bar cage, wherein during pulling the pile tube, the concrete in the pile hole is jolt rammed while the pile tube is pulled. The invention has the advantages of no vibration, no noise and no oily fume environmental pollution, and the length of the pile tube is not limited by the height of the pile pressing frame.

Description

technical field [0001] The invention relates to a concrete pile construction method and its construction machinery in building foundation engineering technology, in particular to a construction method and equipment for a pressure-holding static pressure sinking pipe grouting pile Background technique [0002] In deep foundation projects all over the world, pile foundation is the main means, and concrete pouring pile is the most widely used in pile foundation. Cast-in-situ piles can adapt to changes in various strata without pile connection, can bear large vertical loads, and can also withstand large horizontal loads, and can be embedded in the ground to a certain depth, with good seismic performance and small settlement , can prevent uneven settlement. In the known technology, the existing concrete sinking pipe pile usually adopts the construction method of top pressure hammering, vibration or vibration impact. The corresponding equipment adopts the top-pressure rolling tu...
