Construction method of a pile machine

Abstract

The invention discloses a construction method of a pile planting machine. The construction method comprises the following steps of 1) preparing construction; 2) leveling the ground, and finishing precast hole drilling, excavation and stirring; 3) arranging a plurality of strain gauges on a precast pile body at a certain interval, and selecting a clamping wedged block and a cushion block accordingto the diameter of a precast pile; 4) performing centering adjustment on a clamping mechanism, and debugging the levelness of a working platform; 5) performing adjustment on a fine adjustment mechanism in longitudinal and transverse directions; 6) starting a hoisting mechanism, and hoisting the precast pile to the upper side of the precast hole; 7) manipulating an upper part clamping oil cylinderto enable the clamping wedged block to clamp the pile body and a lower part clamping mechanism to enable a clamping ring to clamp the pile body; and 8) manipulating a vertical jacking oil cylinder toenable the upper part stand to press the precast pile after moving downward, and thus planting the precast pile in the prebored hole. The construction method provided by the invention effectively improves the pile planting accuracy of the precast pile, facilitates up and down butt joint of the precast pile bodies, lowers the construction cost and improves the operation safety of an operator.

Description

technical field [0001] The invention relates to a construction method of a pile planter used for implanting various prefabricated piles into strata, which can carry out underground foundation construction or foundation improvement. Background technique [0002] With the advancement of basic projects such as rail transit, intercity railways, bridges and culverts, urban construction, and underground pipe corridors with the reconstruction of old cities and low-level improvements in construction projects, an integrated drilling, deep mixing, reaming and prefabricated various piles The new pile foundation construction method of the rooted pile combination of the foundation technology has gradually been used and promoted. This construction method has the advantages of no vibration, low noise, good pile quality, high pile bearing capacity and less mud discharge, which is in line with low-carbon energy saving and environmental protection. The industry-oriented approach can effective...

Problems solved by technology

When it is necessary to connect the piles by welding, generally a guide hoop is set at the head of the pile body that has been implanted to facilitate the placement of the piles above the implanted pile body. After the welding is completed, the misalignment error of the upper and lower pile bodies is generally 5-10mm Between, it is difficult to ensure the vertical accuracy and straightness accuracy requirements of the implanted pile body

In addition, when the piles are implanted, the construction company must be equipped with large-scale lifting equipment for lifting various implanted piles into place, resulting in a substantial increase in construction costs

In addition, during the whole pile planting process of prefabricated piles, construction personnel are always located around the prefabricated holes, the environment is harsh, and there are great hidden dangers in operation safety
