Technical Field
The invention relates to the technical field of bridge engineering pile foundation construction, in particular to a device for rapidly chiseling a pile head of a pile foundation.
Background
In the process of pouring the pile foundation concrete, the strength of the pile top concrete at the pile top cannot meet the design requirement due to the factors that the coarse aggregate floats on the surface along with the self-weight lower layer and the slag soil. Therefore, in order to ensure the strength of the concrete on the pile top, the concrete can be over-poured for 1 m in actual construction, and the pile top is chiseled after the concrete reaches the designed strength.
The traditional pile head drilling method is many, but due to various factors, the method used on the spot is still: cutting off the concrete protective layer, and breaking the concrete by using an air pick; the method has the advantages of low construction speed and high labor cost.

a device for rapidly chiseling a pile head of a pile foundation is characterized in that a steel reinforcement cage of the pile foundation is provided with a main rib and a sound measurement pipe, and comprises a jack and an arc-shaped isolation plate matched with the steel reinforcement cage, wherein the isolation plate is provided with a row of mounting holes capable of enabling the main rib to penetrate and a plurality of slurry penetration holes, the isolation plate is discontinuously mounted on the main rib above a designed pile top of the pile foundation, and the isolation plate is obliquely mounted in a separated manner by the sound measurement pipe; a plurality of embedded cylinders are arranged on a main rib between the designed pile top and the isolation plate, jacks can be placed in the embedded cylinders, and one ends of the jacks, which are connected with the pressure pumps, face the inner side of the reinforcement cage.
Furthermore, the top surface and the bottom surface of the embedded cylinder are both welded with round steel plates with diameters larger than that of the embedded cylinder.
Furthermore, a conical cylinder is arranged on the round steel plate on the bottom surface of the embedded cylinder.
Furthermore, there are two pre-buried section of thick bamboo, and the contained angle that two pre-buried section of thick bamboo and the central line of steel reinforcement cage formed is 120 degrees.
Furthermore, before grouting is carried out in the pile foundation, medium coarse sand is filled in the embedded cylinder.
Has the advantages that:
according to the invention, the isolation plate is pre-embedded before the reinforcement cage is lifted, and an isolation effect is formed between pile top concrete and floating slurry concrete; meanwhile, the embedded jacks jack the pile head concrete after the concrete is solidified, floating slurry concrete can be broken, and the construction is simple and efficient.
Drawings
FIG. 1 is a top view of the present invention.
FIG. 2 is a cross-sectional view taken along line A-A of the present invention.
Fig. 3 is a schematic view of the embedding cylinder of the present invention.
In the figure: the steel reinforcement cage comprises a steel reinforcement cage body 1, a main reinforcement 11, a spiral reinforcement 12, a reinforcement stirrup 13, a steel reinforcement cage positioning reinforcement 14, a sounding pipe 15, a pile top of 16 design, a pre-embedded cylinder 2, a circular steel plate 21, a conical cylinder 22, an isolation plate 3, a mortar penetration hole 31, a jack 4, a steel wire 5 and coarse sand 6.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments:
as shown in fig. 1 to 3, a device for rapidly chiseling a pile head of a pile foundation, wherein a reinforcement cage 1 of the pile foundation is provided with a main reinforcement 11 and a sounding pipe 15, and comprises a jack 4 and an arc-shaped partition plate 3 matched with the reinforcement cage 1, the partition plate 3 is provided with a row of mounting holes through which the main reinforcement 11 can pass and a plurality of grout-permeable holes 3131, the partition plate 3 is discontinuously mounted on the main reinforcement 11 above a designed pile top 16 of the pile foundation, and the partition plate 3 is obliquely mounted at intervals by using the sounding pipe 15; a plurality of embedded cylinders 2 are arranged on a main rib 11 between a designed pile top 16 and an isolation plate 3, jacks 4 can be placed in the embedded cylinders 2, and one ends of the jacks 4 connected with a pressure pump face to the inner side of a reinforcement cage 1.
Specifically, the main reinforcement 11, the spiral reinforcement 12, the reinforcement stirrup 13 and the reinforcement cage positioning reinforcement 14 of the reinforcement cage 1 are arranged on the cage rolling machine, so that the reinforcement cage 1 can be conveniently hoisted and connected with the installed reinforcement cage 1 after installation; and the acoustic pipe 15 is bound on the reinforcing stirrup 13, so that the pile foundation can be conveniently detected.
As shown in fig. 3, the embedded cylinder 2 can be made of an iron sheet with a certain thickness into a cylinder, and the top surface and the bottom surface of the embedded cylinder 2 are both welded with a round steel plate 21 with a diameter larger than that of the embedded cylinder 2, so that the embedded cylinder 2 forms a totally closed area to prevent concrete from entering; the pre-buried section of thick bamboo 2 utilizes steel wire 5 ligature on main muscle 11, and coarse sand 6 in the pre-buried section of thick bamboo 2 intussuseption avoids the pre-buried section of thick bamboo 2 of concrete pouring in-process to be shriveled.
Preferably, the circular steel plate 21 on the bottom surface of the embedded cylinder 2 is provided with a conical cylinder 2222, so that the floating concrete can float upwards by using the conical cylinder 2222, and the jack 4 can fully exert the function thereof.
