Construction method for hydraulic vibrating sinking pipe cast-in-place piles

Abstract

The embodiment of the invention discloses a construction method for hydraulic vibrating sinking pipe cast-in-place piles, which is characterized in that an all-casing is taken as a pore-forming breast wall, and the casing is pressed to a designed elevation in one step by using a hydraulic vibrating device, thereby effectively improving the efficiency of construction; meanwhile, in the process of pile forming, the casing is vibrated by using the hydraulic vibrating device, and simultaneously, the casing is pulled out so as to ensure that the concrete is more compact and the quality of a formed pile is higher. The construction method disclosed by the invention is rapid in construction speed and high in efficiency; meanwhile, by using the method, the common quality faults are reduced, the quality of engineering piles is guaranteed, the bearing capacity of the piles is improved, the construction materials are effectively saved, the construction cost is reduced, and therefore, the method is a new green construction technology for pile foundations.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a construction method of a hydraulic vibration sinking pipe cast-in-place pile. Background technique [0002] In recent years, with the development of casing cast-in-place pile construction technology, the safety, economy and environmental protection of the full set of pipe cast-in-place pile construction technology have been verified in construction practice, but the casing pressure in the casing cast-in-place pile is mainly used Hydraulic pile grinding device, casing press-in and jacking speed is slow, and connection and pipe removal time is relatively long, these factors also greatly affect the construction progress of engineering piles, according to the existing construction technology and methods, one set of equipment a day The construction of a cast-in-place pile less than 25m can only be completed, which greatly affects the construction progress of the casing cast-in-place ...

Problems solved by technology

[0002] In recent years, with the development of casing pile construction technology, the safety, economy and environmental protection of casing pile construction technology have been verified in construction practice, but casing pressing in casing piles is mainly used The hydraulic pile grinding device, casing pressing and jacking speed are slow, and the connection and pipe removal time is relatively long. These factors also greatly affect the construction progress of engineering piles. According to the existing construction technology and methods, one set of equipment per day Only one cast-in-situ pile below 25m can be completed, which greatly affects the construction progress of the cast-in-situ pile with casing, which in turn affects the entire project process
