Description

A circular pile breaker for circular bored piles

【Technical field】

The utility model relates to the technical field of bored cast-in-situ pile breaking, in particular to an annular pile breaker for circular bored cast-in-place piles.

【Background technique】

When pouring cast-in-place piles in engineering practice, the elevation of the top of the pile should be 0.5-1.0m higher than the design elevation of the pile to ensure the concrete strength of the pile head, but the part of the pile head that is higher than the design elevation of the pile top must be removed during subsequent construction. Chiseling, the process of chiseling the pile head higher than the design elevation of the pile top is called breaking the pile. In addition, breaking the pile also prevents the impact of the concrete necking phenomenon on the diameter of the pile due to the lateral force of the soil, and drives out the main reinforcement in the pile as a The reinforcement of the platform, etc.

At present, the main method of breaking piles in domestic engineering practice is to break piles by manually operating a pile breaking machine. This method of breaking piles is labor-intensive and the efficiency of breaking piles is low. In addition, there is also a new technology of hydraulic air hammer to break piles. Although this pile breaking technology improves the efficiency of pile breaking, it generally has disadvantages such as complex pipeline system, high cost, and difficult diagnosis and elimination of faults.

【Content of utility model】

The technical problem to be solved by the utility model is to provide a ring-shaped pile breaking machine for circular bored piles. Under the drive of electric power, the vibrating drill bit can move along the ring-shaped guide rail in the guide rail chute to realize the function of continuous cycle pile breaking , improve the efficiency of pile breaking and reduce the labor intensity of pile breaking.

In order to achieve the above purpose, the technical solution provided by the utility model is: a circular pile breaker for circular bored piles, which is characterized in that it consists of a circular guide rail, a fixing bolt, a guide rail chute, a limit hole, a power switch, a power supply It is composed of line, limit hole frame, limit slide rod and vibrating drill bit. There are two annular guide rails, which are circular, and are arranged horizontally up and down respectively, and guide rail slide grooves are arranged in the annular guide rails; there are four fixing bolts, which are respectively arranged at the two ends of the outer sides of the two annular guide rails; There are two limiting hole frames described above, and the two ends of each limiting hole frame are respectively arranged in the guide rail chute on the same side of the two circular guide rails, and each limiting hole frame is provided with upper and lower rows of limiting holes; There are two limit slide rods, the upper and lower ends of which are respectively connected to the upper and lower rows of limit holes on the same side, and the limit slide rods can slide along the limit holes; there are two vibrating drill bits, respectively At the front ends of the two limit slide bars, the vibrating drill bit can rotate; the power switch is arranged on the limit hole frame; the power line is drawn out from the limit hole frame.

The beneficial effects of the utility model are: the utility model can realize the function of breaking piles in continuous circulation, improve the efficiency of breaking piles, and reduce the labor intensity of breaking piles.

【detailed description】

In the example shown in the accompanying drawings, a ring-shaped pile breaker for circular bored piles is characterized in that it consists of a ring guide rail, a fixing bolt, a guide rail chute, a limit hole, a power switch, a power cord, and a limit hole. Frame, limit slide bar, vibrating drill bit. There are two annular guide rails, which are circular, and are arranged horizontally up and down respectively, and guide rail slide grooves are arranged in the annular guide rails; there are four fixing bolts, which are respectively arranged at the two ends of the outer sides of the two annular guide rails; There are two limiting hole frames described above, and the two ends of each limiting hole frame are respectively arranged in the guide rail chute on the same side of the two circular guide rails, and each limiting hole frame is provided with upper and lower rows of limiting holes; There are two limit slide rods, the upper and lower ends of which are respectively connected to the upper and lower rows of limit holes on the same side, and the limit slide rods can slide along the limit holes; there are two vibrating drill bits, respectively At the front ends of the two limit slide bars, the vibrating drill bit can rotate; the power switch is arranged on the limit hole frame; the power line is drawn out from the limit hole frame.

The utility model is suitable for crushing circular bored cast-in-situ piles. When using the utility model, the upper and lower annular guide rails of the present utility model are firstly placed on the periphery of the circular bored cast-in-place piles to be broken, and the fixing bolts at the two ends of the outer sides of the annular guide rails are used. Fix the cast-in-place pile tightly, then connect the power cord of the utility model, and turn on the power switch on the limit hole frame. At this time, the two vibrating drill bits at the front end of the limit slide bar start to rotate, and advance toward the center of the cast-in-situ pile section while rotating. At the same time, the two limiting hole frames start to rotate around the circular guide rail in the same direction through the guide rail chute of the circular guide rail, so as to continuously rotate and break the pile. The upper and lower ends of the slide bar move continuously toward the center of the cast-in-place pile section along the two rows of limit holes on the same side, so as to push the vibrating drill bit at the front end of the limit slide bar to continuously advance toward the center of the cast-in-place pile section, and finally realize the continuous drilling of the utility model. The function of rotating pile breaking improves the efficiency of pile breaking and reduces the labor intensity of pile breaking.

After the pile breaking is completed, stop using the utility model, close the power switch on the limit hole frame, disconnect the power cord of the utility model, loosen the fixing bolts at both ends of the ring guide rail outside, and take off the utility model.
