Problems solved by technology

[0003] However, the piles formed by this construction technology have an insurmountable shortcoming: because the piles are constructed by using long auger holes to drill to the design depth and pouring at the same time, the hole forming and pouring are completed at the same time, and only the pouring flow state and superfluid fillers, forming piles with plain concrete piles
But still do not have a kind of machine that is specially aimed at this kind of pile foundation construction operation so far

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] like figure 1 As shown, a shared pile driver mast 5 is installed on the walking chassis 6 of the walking pile driver. The static pile pressing mechanism that pile core pile presser 7, pile core guider 9, pile presser pressurizing rope 12 form. The long auger drill pipe 3 and the long auger power head 4 are suspended on the mast 5 of the pile driver, and the weight of the three plus the weight of the walking chassis 6 of the pile driver can all be pressed on the prefabricated reinforced concrete plug by the pile presser rope 12. On the core 8, the insert core has enough downward pressure to be pressed into the plain concrete pile body. If the pile pressure is still not enough, the long auger drill pipe can be drilled into the ground to a certain depth to make it a ground anchor to provide additional pressure piles. Reaction force.

Abstract

The invention discloses a construction machine for long helical grouting concrete core-inserted composite piles. A long helical drilling and grouting pile mechanism and a static pressure pile mechanism are installed side by side on the walking chassis of a walking pile machine. The long helical auger The center points of the hole-pressing pile filling mechanism and the pile-pressing mechanism are all located on the same circle centered on the center point of the turntable of the traveling chassis of the pile machine. After the long spiral construction is completed, the static pile-pressing mechanism can be quickly aligned only by turning the turntable. The pile driver can independently complete the construction of the long spiral pressure grouting concrete core-inserted composite pile, and has the advantages of convenient construction, reliable quality and low construction cost.

Description

technical field [0001] The invention relates to a construction machine for pile foundations of buildings, in particular to a construction machine for long screw-pressed concrete core-inserted composite piles. Background technique [0002] In the prior art, the common long auger drilled in-pipe pump pressure cast-in-situ pile construction machinery is a construction system consisting of auger drills, concrete pumps, etc., and is widely used in pile foundation construction. It is mainly composed of a drilling rig chassis, a mast , slideway, power head, auger drill pipe and concrete delivery pump delivery pipeline etc. The construction procedure is: the drilling rig is in place and drilled to the predetermined elevation, the concrete is mixed in the mixer according to the given ratio in advance, the mixed concrete is put into the concrete pump hopper through the chute, the concrete pump is started, and the concrete is pumped into the drill through the delivery pipeline.
