Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

An auxiliary device for breaking a concrete pile head of a bored pile is shown in figure 1 and comprises a body 1, wherein the body 1 can be set into any shape, in order to better work, the body 1 can be set into a hollow cylinder shape, a support frame 2 is integrally formed at the bottom of the body 1, the support frame 2 can be arranged in a cross shape, a vibration device 3 is fixedly arranged at the center of the support frame 2, the support frame 2 can be set into a thin structure so as to reduce the resistance of the support frame, and meanwhile, the structural strength of the support frame can be ensured to be enough to support the operation of the whole equipment; the vibration device 3 can be selected from a common concrete vibrator in the industry, namely a machine tool for tamping by utilizing the vibration action when concrete is poured, the machine tool is driven by electric power or compressed air to rotate eccentrically or impact reciprocally and vibrate quickly, and the vibration device can be arranged above the support frame 2 or below the support frame 2 under the condition of not influencing the operation.

Be provided with pipe 4 simultaneously on body 1, pipe 4 is hollow setting, and can be at pipe 4 inner loop for water, can set up pipe 4 to the type of returning, set up to two ring structures from top to bottom as shown in the figure, through a plurality of pipe connection between two rings, a plurality of delivery port 5 has been seted up on ring and pipeline, can connect external water tank through rubber hose on the ring, and can input water into pipe 4 through the booster pump, make the delivery port can be ceaselessly spray water to all directions.

The working principle of the scheme is as follows: when concrete pouring in the reinforcement cage exceeds a preset height, the body 1 is placed into concrete, the vibration device 2 is started, the vibration device 2 can gradually sink into the concrete in the process of deflection rotation of the vibration device 2, impact vibration can be continuously generated on the concrete in the sinking process, and therefore the concrete is compacted, the concrete is better contacted with the reinforcement cage, meanwhile, in order to ensure the position of the body 1 in the concrete, the tail end of the support frame 2 extends for a stroke to form a limiting column 6, the limiting column 6 can be abutted to the upper end face of the reinforcement cage, when the vibration device 2 drives the body 1 to sink, the limiting column 6 cannot sink any more when abutting to the end face of the reinforcement cage, so that the concrete in the reinforcement cage cannot be damaged, and the compaction effect can be achieved; certainly, it is more preferable that the tail end of the limiting column 6 can be fixedly provided with the elastic part such as a spring, one section of the spring is fixed on the limiting column 6, and the other end of the spring can abut against the side wall of the reinforcement cage, so that the vibration can be better buffered in the vibration process. In the sinking process of the vibrating device 2, the water outlet 5 of the conduit 4 continuously sprays water, so that the concrete above the reinforcement cage can be diluted, if water is only poured from the outside, the dilution effect cannot be realized, because the water cannot enter the concrete, the concrete above the reinforcement cage can be changed into a cement state only by sinking the conduit 4 into the concrete for water spraying dilution, and the structural strength of the concrete is relatively low, so that the concrete can be easily broken; the breaking cost can be greatly reduced; in order to conveniently take out the body 1 after construction is completed, the lifting columns 7 are fixedly mounted on the body 1, the lifting columns 7 can be provided with a plurality of lifting columns, the height of each lifting column 7 needs to be higher than that of the guide pipe 4, workers can conveniently take out the body 1 from concrete by contacting the lifting columns, scales can be marked on the lifting columns 7, and the workers can know the depth of the body immersed in the concrete at any time, so that the working progress is known; after the body reaches the position, can arrange the staff at any time and take out the body, avoid directly fixing in the concrete by the concrete when solidifying.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the fan belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that modifications and embellishments within the scope of the present disclosure may be made by those skilled in the art without departing from the principles of the present disclosure.
