Pile hole casting adjustment structure

Abstract

The invention discloses a pile hole casting adjustment structure which comprises a roller and two columns. A feeding pipe is communicated with a flow way, a cavity communicated with the flow way is formed in the roller, two small holes are formed in the outer circumferential wall of the roller, and each small hole is connected with a casting pipe. A buffer cavity is formed in a casting head in theperipheral direction of the casting head, two casting holes are formed in the upper surface of the casting head and are connected with the casting pipes, multiple grooves are formed in the lower surfaces of the casting holes, through holes are formed in the bottoms of the grooves, partition plates are fixed to the walls of the grooves, universal balls are arranged on the partition plates, the upper ends of adjusting pipes penetrate through the middles of the universal balls, and two ends of a hose are connected with the bottom of the buffer cavity and the upper ends of the adjusting pipes. After a concrete pile sinks, concrete grout is injected into a pile hole, excessive concrete grout is extruded out of the pile hole, concrete grout waste is avoided, and meanwhile overflowing concrete grout is prevented from polluting the environment or a construction period is prevented from being prolonged.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a pile hole grouting adjustment structure. Background technique [0002] At present, the construction methods of prefabricated concrete piles basically adopt the hammering method and the static pressure method. The main defects of these two methods of pile driving are: to produce a soil squeezing effect, which will affect the engineering pile and the surrounding original facilities; It is difficult to control, and the integrity of the pile body cannot be guaranteed; the vibration and noise generated by the hammering method will affect the surrounding environment. Therefore, there are many disadvantages in the pile sinking construction using the hammering method or the static pressure method. The rooted pile is drilled with a drilling rig, the soil in the hole is stirred into mud, and the concrete slurry is injected into the mud hole to make a mud hole larger than the pile dia...

[0002] At present, the construction methods of prefabricated concrete piles basically adopt the hammering method and the static pressure method. The main defects of these two methods of pile driving are: to produce a soil squeezing effect, which will affect the engineering pile and the surrounding original facilities; It is difficult to control, and the integrity of the pile body cannot be guaranteed; the vibration and noise generated by the hammering method will affect the surrounding environment. Therefore, there are many disadvantages in the pile sinking construction using the hammering method or the static pressure method

However, this method needs to pour concrete slurry into the mud hole to form a mixed slurry before sinking the pile. The discharge volume of the mixed slurry is the actual volume of the prefabricated concrete pile or concrete pipe pile, and the discharged mixed slurry contains concrete slurry, resulting in waste, while affecting the environment, and the overall construction progress is slow
