Problems solved by technology

[0003] Usually the height of the pile driver is more than 8 meters. The clearance height of the old building itself is difficult to meet the construction requirements. If the pile construction is to be carried out, the floor slab can only be removed to the third floor.
However, removing the second and third floor slabs at the same time is extremely detrimental to the lateral stability of the building, causing serious safety hazards

Embodiment approach

[0020] In the first embodiment of the present invention, please continue to refer to figure 1 with figure 2 shown. The above-mentioned detachable device 4 is a plurality of pile frame sections 41 with the same shape and structure. These several pile frame sections 41 form the pile frame 2 by being superimposed and connected with each other. By adding or removing the pile frame sections 41 one by one Increase or reduce the height of the pile frame 2, so that the pile driver enters the room with limited height to carry out the normal construction of the pile.

[0021] In the second embodiment of the present invention, the injection device 3 includes a suction pump 31 and a mud pipe 32, and the mud pipe 32 is connected with the suction pump 31 so that the mud is sucked by the suction pump 31 and passed through the mud pipe 32. Exhaust outward.

[0022] In the third embodiment of the present invention, the driving device 5 includes an air pressure valve 51 and a cylinder 52, t...

Abstract

The invention discloses an ultralow headroom pile machine which comprises a pile frame undercarriage, a pile frame arranged on the pile frame undercarriage in a hinged manner and a transmission device. A jet device is arranged at the upper end of the pile frame which comprises a detachable device, the height of the pile frame can be adjusted by adding or demounting the detachable device, the pile frame undercarriage is provided with at least one driving device which is connected with the lower end of the pile frame to drive the pile frame to sway along a hinged portion, and the transmission device is fixedly arranged on the pile frame undercarriage and connected with the jet device to transmit the jet device to lift along the pile frame. Compared with common pile machines, the overall height of the pile frame is changed by demounting pile frame joints one by one to enable the pile machine to enter certain indoor places with height limits for normal construction of piles.

Description

technical field [0001] The invention relates to a protective device in the construction field, in particular to a pile foundation construction under an ultra-low headroom realized by the transformation of a pile frame. Background technique [0002] With the changes of the times, many protected buildings have problems in terms of function and safety. This situation has led to many old buildings needing renovation to restore their functions. Due to the restrictions of cultural relics protection regulations, old buildings cannot be destroyed and rebuilt at will, so they have to be rebuilt under limited conditions. [0003] Usually the height of the pile driver is more than 8 meters. The clearance height of the old building itself is difficult to meet the construction requirements. If the pile construction is to be carried out, the floor slab can only be removed to the third floor. However, demolition of the second and third floor slabs at the same time is extremely unfavorable...
