[0002] As a new construction method for a supporting structure, the casing biting pile refers to a reinforced concrete "pile wall" formed by the adjacent piles in the plane arrangement biting each other (the circumferences of the piles are embedded). It is particularly suitable for soft soil areas with silt, quicksand, and rich groundwater. Compared with ordinary bored supporting piles, it greatly improves the shear strength and safety of the supporting structure, and at the same time has a good water-stop function; compared with diaphragm walls, it has the advantages of lower reinforcement ratio and flexible construction.

[0035] Among them, the construction pile columns 1 are symmetrically arranged on the left and right sides of the biting transfer pile column 2 to form an arrangement combination of the construction pile column 1, the biting transfer pile column 2, and the construction pile column 1.

[0036] In this embodiment, referring to Figure 1 、 2 and Figure 3, the biting transfer pile column 2 is composed of a circular steel bar 201 and a vertical steel bar 202 combined and tied. A supporting chassis 203 is arranged at the lower end of the vertical steel bar 202. An annular groove 204 is opened on the upper side of the supporting chassis 203, and a lifting frame 205 is arranged on the upper side of the supporting chassis 203; through the annular groove 204 opened on the supporting chassis 203, positioning and supporting of the steel reinforcement cage composed of the vertical steel bar 202 and the circular steel bar 201 can be realized, so that the stability of the steel reinforcement cage after being put in is high, and the steel reinforcement cage can be better positioned and placed.

[0038] In this embodiment, referring toFigure 1 As shown in FIGS. 4 - 9, the casing assembly 3 includes a construction casing 301. A transfer groove 302 is formed in the upper end face of the construction casing 301. Positioning blocks 303 are arranged corresponding to each other front and back inside the transfer groove 302. A construction mouth protector 3031 is installed at the upper end of the construction casing 301 through the transfer groove 302. An adapter plate 304 is arranged on the side of the construction mouth protector 3031. A limiting pressure plate 305 is installed on the lower side of the other end of the adapter plate 304. A limiting block 306 is arranged at a point on the lower side of the limiting pressure plate 305. A positioning cavity 3061 is formed in the side wall of the upper end of the construction casing 301, and a limiting mechanism 307 is arranged inside the positioning cavity 3061. The formation of the transfer groove 302 at the end of the construction casing 301 in the casing assembly 3 enables the installation and transfer of the construction mouth protector 3031 and the transfer positioning of the transfer casing 316 to be highly convenient. Moreover, the positioning blocks 303 arranged inside the transfer groove 302 enable the transfer between the transfer casing 316 and the construction casing 301 to have a relatively stable construction transfer effect during construction rotary cutting, making the transfer between the transfer casing 316 and the construction casing 301 highly safe during construction transfer operations. The positioning cavity 3061 enables the limiting pressure plate 305 and the limiting block 306 to have a better adjustment space during transfer with the limiting mechanism 307, so that the limiting block 306 can better transfer with the limiting mechanism 307, and the installation and positioning effect of the construction mouth protector 3031 is good.

[0039] The limiting mechanism 307 includes bearing seats 308 installed corresponding to each other left and right inside the positioning cavity 3061. A positioning shaft 309 is rotatably installed on the bearing seats 308. Positioning discs 310 are installed at both ends of the positioning shaft 309. First connection grooves 311 are formed on the side edges of the positioning discs 310. Second connection grooves 312 are formed on the lower side faces of the bearing seats 308. A torsion spring 313 is arranged on the positioning shaft 309 between the bearing seats 308 and the positioning discs 310. A positioning block 314 is arranged at the middle of the positioning shaft 309. A positioning clamping seat 315 is arranged on the upper side of the outer end of the positioning block 314. The positioning block 314 and the positioning clamping seat 315 in the limiting mechanism 307 can achieve a good limiting effect on the limiting block 306. The torsion spring 313 can enable the positioning block 314 to rotate and change. When one end of the positioning block 314 is pressed, the positioning clamping seat 315 realizes the limiting clamping of the limiting block 306. When the pressure on one end of the positioning block 314 is released, the positioning clamping seat 315 separates from the limiting block 306, so that the disassembly of the construction mouth protector 3031 is simple and convenient.

[0040] The construction casing 301 further includes a transition casing 316. The upper end structure of the transition casing 316 is arranged in the same structure as that of the construction casing 301. The lower end structure of the transition casing 316 is adapted to the transition groove 302. A positioning slot 317 is correspondingly formed at the lower end of the transition casing 316 corresponding to the positioning block 303. The transition through the transition casing 316 can be achieved between the construction casing 301, so that the laying depth of the pile column can be better excavated. Through the positioning slot 317, the transition casing 316 can be better positioned and transferred with the construction casing 301, and the use stability of the transition casing 316 and the construction casing 301 during the excavation of the construction hole is high, enabling the project to have a better construction progress.

[0041] The lower end of the construction casing 301 is arranged in a serrated structure, and the construction mouth protector 3031 is arranged in a "flared" structure. The lower end of the construction mouth protector 3031 is arranged in a structure adapted to the transition groove 302. A limit slot 318 is correspondingly formed at the lower end of the construction mouth protector 3031 corresponding to the positioning block 303. By arranging the construction mouth protector 3031 in a flared structure, the earth-scooping grab can more conveniently enter the interiors of the construction casing 301 and the transition casing 316 for earth-taking work, and the earth-scooping grab has a high earth-taking efficiency for the interiors of the construction casing 301 or the transition casing 316.

[0042] Among them, the first connection groove 311 and the second connection groove 312 are formed in a diagonal arrangement based on the positioning shaft 309 as the center line. The two ends of the torsion spring 313 are correspondingly clamped with the first connection groove 311 and the second connection groove 312 respectively. One end of the limit pressing block 306 is arranged in an "arc-shaped" structure, and the limit pressing block 306 is adapted to the structure of the positioning seat 315. The side cross-section of the limit pressing plate 305 is arranged in an "L"-shaped structure. By arranging one end of the limit pressing block 306 in an "arc-shaped" structure, the limit pressing block 306 can be better moved and regulated when horizontally pressing the positioning block 314. By arranging the limit pressing block 306 to be adapted to the structure of the positioning seat 315, the positioning seat 315 can better press and position the limit pressing block 306, so that the transition positioning effect of the construction mouth protector 3031 is good.

[0043] When the casing secant pile of this solution is in construction use, when constructing the construction pile column 1, a drill hole is made through the construction casing 301 under the action of mechanical operation. Then, the construction casing mouth 3031 is docked with the construction casing 301. By corresponding the limit pressing plate 305 with the positioning cavity 3061, the corresponding of the limit pressing block 306 and the positioning block 314 is realized. At the same time, the construction casing mouth 3031 is corresponded with the transfer groove 302. When the construction casing mouth 3031 and the transfer groove 302 are pressed and grabbed downwards, at the same time, the limit pressing block 306 presses one end of the positioning block 314, so as to realize the clamping and limiting of the positioning clamping seat 315 on the limit pressing block 306, and realize the transfer between the construction casing mouth 3031 and the construction casing 301 or the transfer casing 316, so that the earth-shoveling grab can better enter the interior of the construction casing 301 for earth-taking construction. At the same time, the transfer positioning between the construction casing mouth 3031 and the construction casing 301 or the transfer casing 316 has high convenience and stability, effectively improving the earth-taking efficiency during the pile column construction. When the construction of two groups of construction pile columns 1 is completed, the construction pile column 1 is cut through the construction casing 301 to realize the opening of the secant construction groove 101;

[0044] The hoisting frame 205 is grabbed by the earth-shoveling grab, so as to realize placing the supporting chassis 203 in the secant construction groove 101 opened by two groups of construction pile columns 1. When the laying of the supporting chassis 203 is completed, the construction casing 301 is put into the secant construction groove 101 by the machine. The steel reinforcement cage composed of the vertical steel bars 202 and the circular steel bars 201 after laying and binding is hoisted and put into the construction casing 301 for pouring construction, forming the arrangement and combination of the construction pile column 1, the secant transfer pile column 2, and the construction pile column 1 for construction use.
