Cement concrete cored pile construction integrated type cored pile driver and construction method thereof

Abstract

The invention discloses a cement concrete cored pile construction integrated type cored pile driver. The cement concrete cored pile construction integrated type cored pile driver comprises a mixed pile machine for implementing construction of cement mixed piles, and a pile driving device for pressing core piles into cement-mixed piles, wherein the pile driving device is mounted onto the mixed pilemachine and comprises a pile driving platform, a vibrating hammer, a guiding rack for guiding the vibrating hammer, and a pile conveyer arranged at the bottom of the vibrating hammer. Meanwhile, theinvention also discloses a cement concrete cored pile construction method. The cement concrete cored pile construction method comprises the steps of setting of the mixed pile machine, construction ofthe cement-mixed piles, displacement of the mixed pile machine, installation of the core piles, vertical driving of the core piles and pile pressing. The cement concrete cored pile construction integrated type cored pile driver is reasonable in design, simple in construction, high in construction efficiency and good in use effects, capable of completing construction of the cement-mixed piles and pressing of the core piles during construction of cement concrete cored piles, and high in construction speed; meanwhile, during the pile pressing process, the perpendicularity of the core piles is easy to control to effectively ensure the quality of the constructed cement concrete cored piles and guarantees the treatment effects of land foundation reinforcement.

Description

technical field [0001] The invention belongs to the technical field of pile foundation construction, and in particular relates to an integrated cored pile machine and a construction method for cement concrete cored pile construction. Background technique [0002] Core-filled mixing piles are composed of cement-soil mixing piles (also known as cement mixing piles) and concrete core piles. Before the cement-soil mixing piles are made into initial setting, prefabricated concrete core piles or recast concrete core piles are pressed into them with special equipment. And the composite pile formed. The cored mixing pile has the characteristics of high bearing capacity, low settlement, low cost, environmental protection, and wide application range. In today's railway construction process, the widely used cement concrete cored piles are cored mixing piles. The cement concrete cored piles closely combine the cement-soil mixing piles and concrete core piles, and the two are organicall...

AI Technical Summary

Problems solved by technology

At present, when constructing cored mixing piles, the cement mixing piles are firstly constructed with a mixing pile machine, and then the pre-processed core piles are pressed into the cement mixing piles with a pile driver or pile pressing equipment added to the excavator. Therefore, it is necessary to configure pile pressing equipment separately, which has high investment cost, and the simultaneous use of pile pressing equipment and pile mixing machine requires a large construction space, limited construction occasions, slow construction speed, and low construction efficiency. The verticality control is poor, resulting in a reduction in the bearing capacity of the pile composite foundation and affecting the quality of the project
