Description

Technical Field

[0001] The invention relates to the technical field of foundation pit engineering, in particular to an adjustable assembled grouting steel pipe reinforced concrete inclined pile support and a construction method thereof. Background Art

[0002] Inclined pile support refers to the inclined support set around the pile body, which enhances the stability of the pile through the inclined support effect. It usually uses steel lattice columns as support piles, and the ends are pressurized by cement soil. The steel lattice columns bear axial force, bending moment and cement soil friction. Concrete crown beams are implanted at the top of the steel lattice columns to form an inclined support system to resist the lateral pressure of the side wall of the foundation pit.

[0003] For example, a Chinese patent application with authorization announcement number CN218667560U discloses a precast concrete pile and steel lattice combined diagonal brace, comprising precast concrete square piles and steel lattice; the upper part of the precast concrete square piles is connected to a top beam; the precast concrete square piles are located below the bottom of the foundation pit and serve as diagonal piles under the diagonal brace to provide resistance; the part located above the bottom of the pit serves as a support together with the steel lattice; the steel lattice is arranged at the place where the precast concrete square piles pass through the foundation bottom plate; the steel lattice is sleeved on the periphery of the precast concrete square piles; and the foundation bottom plate is integrally connected to the combined diagonal brace by casting.

[0004] However, the above patent still has some problems. Although the above structure can support the soil layer, it is impossible to apply compressive stress to the deformation area under the external load before the structure is subjected to the external load. Therefore, when the inclined pile support is subjected to a pressure exceeding its load, the inclined pile support will be deformed.

[0005] Therefore, how to apply a certain prestress before the inclined pile supports bear external loads to improve the stiffness of the inclined pile supports is a problem that needs to be solved at present. Summary of the invention

[0101] Description of the working principle: When it is necessary to adjust the pasting position of the strain gauge and enable the first detection unit 31 or the second detection unit 33 to move in the length direction of the adjustable assembled steel corbel, the clamping assembly 324 located in the front does not move, and the clamping cylinder 3241 in the clamping assembly 324 located in the rear starts to work. The moving clamping cylinder 3241 can drive the slider 3243 to move in the length direction of the clamping slide rail 3242, thereby adjusting the angle between the hinge 3244 and the slider 3243. The moving hinge 3244 can drive the clamping arm 3245 to move, so that the clamping arm 3245 can move away from the adjustable assembled steel corbel. When the clamping arm 3245 is away from the adjustable assembled steel corbel, the first movable The displacement assembly 323 on the seat 321 starts to work, and the displacement motor 3231 starts to work at this time. The moving displacement motor 3231 can drive the driving gear 3232 to rotate, and then the moving driving gear 3232 can drive the driven gear 3233 to rotate. Since the driven gear 3233 is sleeved on the transmission shaft 3234, it can drive the connecting rod 3235 to start moving. Through the provided guide rod 322, the angle between the two movably connected connecting rods 3235 can be changed, and the distance between the two first movable seats 321 can be shortened. Then the clamping assembly 324 located at the rear moves in the opposite direction, so that the clamping arm 3245 can complete the clamping work of the adjustable assembled steel bracket, and the clamping assembly located at the front The component 324 and the displacement component 323 repeat the above process, so that the first movable seat 321 in the front is away from the first movable seat 321 in the rear, thereby driving the first detection unit 31 and the second detection unit 33 to move in the length direction of the steel bull leg and changing its detection area; the steel bull leg passes through the support seat 311, and the detection area of ​​the first detection unit 31 can be adjusted under the operation of the displacement unit 32. When it is located at a predetermined position, the limit cylinder 312 starts to work, and the moving limit cylinder 312 can drive the adjustment block 313 to move, thereby driving the driving rod 314 to move. The moving driving rod 314 can drive the driving disk 316 to rotate through the set driving shaft. Since the driving disk 316 is provided with a hexagonal through hole Therefore, when the abutment block 3184 is located at the intersection of the side lengths of the hexagonal through hole, the distance between the adjacent limit blocks 3181 is the largest. Conversely, when the abutment block 3184 is located at the midpoint of the side length of the hexagonal through hole, the distance between the adjacent limit blocks 3181 is the smallest. By adjusting the distance between the adjacent limit blocks 3181, the first detection unit 31 can be installed at a predetermined position; when the steel corbel is deformed, the deformed steel corbel will cause the spring compression amount in the limit portion 318 of the biased position to increase, thereby changing the displacement of the limit rod 3182 on the sleeve 3183, and then measure its displacement through a visual acquisition device and compare it with the initial displacement, so as to estimate the deformation amount of the steel corbel;When the strain gauge needs to be pasted at a predetermined position, the adjusting cylinder 332 starts to work. The moving adjusting cylinder 332 can drive the transmission disk 334 to move in the axial direction of the support tube 333, and adjust the linear distance between the transmission disk 334 and the hinge seat 337, so as to change the angle between the support rod 335 and the flip plate 336, so that the flip plate 336 can flip and extend forward a predetermined length, and then the movable cylinder 353 starts to work, so that the first base 351 and the second base 352 rotate, and at the same time the servo motor 354 starts to work, and the moving servo motor 354 can drive the main gear 355 to rotate, and the moving main gear 355 can drive the sub-gear 356 to rotate. Thus, the position of the strain gauge on the adsorption part 357 is adjusted so that the length direction of the strain gauge and the length direction of the steel bracket form a predetermined angle. In the actual working process, under the movement of the adjusting cylinder 332, the flip plate 336 can be driven to flip and extend forward, and then the angle between the strain gauge and the plane where the steel bracket is located is adjusted by the movable cylinder 353. After the movable cylinder 353 completes the adjustment work, there is still a small angle difference between the strain gauge and the plane where the steel bracket is located. Then, by the movement of the adjusting cylinder 332 again, not only the angle difference between the two can be reduced, but also the strain gauge with glue attached can be pressed to the predetermined position on the steel bracket, completing the installation of the strain gauge. ;
