[0026] Embodiment 1 The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 5 , this application provides an assembled pile foundation construction platform and pile foundation construction method, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , including a platform frame 1; the platform frame 1 is composed of four groups of main beams 101, and multiple groups of platform plates 102 are assembled inside the main beams 101. The inner wall of the main beam 101 is provided with a rectangular slot corresponding to the plug-in installation of the platform plate 102, and the inside of the platform plate 102 is provided with a pile position groove 103, and the top of the pile position groove 103 is clamped and installed with a sealing plate 104, and the bottom of the platform plate 102 is installed with a pile position adjustment mechanism 4, and the outer side of the platform frame 1 is installed with an assembly mechanism 5, and the four corners of the bottom of the platform frame 1 are installed with a leveling mechanism 2; The assembly mechanism 5 includes a fixed plate 501, a rotating buckle 502 and a fixed pin 503. The fixed plate 501 is fixedly installed on the outer surface of the platform frame 1. The fixed plate 501 is connected to the rotating buckle 502 through a coil spring structure. The rotating buckle 502 is rotatably installed on the front of the fixed plate 501. The rotating buckle 502 is an existing spring buckle. The two groups of main beams 101 are vertically penetrated by the fixing pin 503. The insertion end of the fixing pin 503 is rectangular, and a rectangular slot corresponding to the insertion end of the fixing pin 503 is provided in the main beam 101.

[0027] Please refer to Figure 4A second limiting block 5021 is installed on the side of the rotating buckle 502, and a first limiting block 5011 is installed on the fixing plate 501 near the top of the second limiting block 5021, and the first limiting block 5011 and the second limiting block 5021 are relatively limited and fitted.

[0028] Specifically, before the construction of the assembled pile foundation of the water conservancy project, it is necessary to splice the three sets of main beams 101, and the assembly mechanism 5 is used to fix the main beams 101, by inserting the fixing pins 503 into the inside of the two vertical sets of main beams 101, and then rotating the rotating buckle 502, so that the rotating buckle 502 is rotated with the fixing plate 501 as the connection point, and the rotation direction of the rotating buckle 502 is perpendicular to the fixing pin 503, and then the rotating buckle 502 will be stuck on the fixing pin 503, and the position of the fixing pin 503 can be fixed by rotating the buckle 502, so that the two vertical sets of main beams 101 can be assembled and fixed, and this method can be used to facilitate the work The author disassembled it later. When the worker rotated the rotating buckle 502, its rotation position could be limited by the limit block 2 5021 and the limit block 1 5011. Then, multiple sets of platform plates 102 were assembled between the three sets of main beams 101 by plugging. The last set of main beams 101 was fixed on one side of the notch of the three sets of main beams 101 in the same way. Then, the sealing plate 104 at the corresponding position to be drilled was taken out, so that the drilling machine could drill the foundation through the pile position groove 103 later. The pile position adjustment mechanism 4 is used to adjust the distance between the two sets of pile positions, and the leveling mechanism 2 is used to adjust the horizontal use position of the platform frame 1.

[0029] Please refer to Figure 3 A fixing groove 1011 is provided at the top of the main beam 101, and a buffer rod 1012 is installed at the bottom of the platform frame 1. The buffer rod 1012 is composed of a telescopic rod and a spring. A spring is wound around the outer side of the telescopic rod, and a buffer block 1013 is installed at the bottom end of the buffer rod 1012.

[0030] Specifically, in order to prevent the main beam 101 of the prefabricated pile foundation construction of the water conservancy project from being damaged by collision during transportation, multiple groups of main beams 101 are stacked and the buffer block 1013 at the bottom of the buffer rod 1012 is stuck in the fixed groove 1011 at the top of another group of main beams 101. The multiple groups of main beams 101 can be stacked and transported. The vibration generated during transportation will be buffered by the elastic deformation of the buffer rod 1012 itself. The buffer rod 1012 can prevent the two groups of main beams 101 from colliding during transportation, thereby preventing the main beam 101 from being damaged by collision during transportation.

[0031] Please refer to Figure 3 The leveling mechanism 2 includes a hydraulic rod 201 and a support leg 202 . The hydraulic rod 201 is installed at the four corners of the bottom of the platform frame 1 , and the support leg 202 is installed at the movable end of the hydraulic rod 201 .

[0032] Please refer to Figure 1 A level 6 is fixedly installed on the outer surface of the platform frame 1.

[0033] Specifically, in order to adjust the horizontal use position of the platform frame 1 for the prefabricated pile foundation construction of a water conservancy project, the change in the internal hydraulic pressure of the hydraulic rod 201 can prompt its telescopic end to drive the support legs 202 to move. By using four groups of hydraulic rods 201 to drive one group of support legs 202 to move respectively, the horizontal use position of the platform frame 1 can be adjusted, and the spirit level 6 can assist workers in adjusting the level of the platform frame 1.

[0034] Please refer to Figure 3 A fixing plate 3 is fixedly installed on the outer side of the supporting foot 202, and a plurality of groups of ground nails 301 are installed on the bottom of the fixing plate 3.

[0035] Please refer to Figure 3 The ground nails 301 are distributed in a circle at the bottom of the fixed plate 3 .

[0036] Please refer to Figure 3 A support rod 302 is installed on the top of the fixed plate 3, and the top of one end of the ground nail 301 is connected to the bottom of the platform frame 1.

[0037] Specifically, in order to achieve the auxiliary support and fixation effect on the platform frame 1 of the prefabricated pile foundation construction of the water conservancy project, when the worker places the device on the ground with a drilled hole, the ground nails 301 at the bottom of the fixed plate 3 will be inserted into the soil, which can assist in fixing the device and prevent it from moving. At the same time, as the hydraulic rod 201 moves the support leg 202 and the support leg 202 is subjected to force, the ground nails 301 will be better inserted into the soil, and the support rod 302 can facilitate the worker to set up a protective net to prevent the worker from falling when working on the surface of the device, thereby improving the safety performance of the device.

[0038] Please refer to Figure 2 The pile position adjustment mechanism 4 includes a double-arm telescopic structure 401 and a pile position frame 402. The double-arm telescopic structure 401 is fixedly installed at the bottom of the platform plate 102. The double-arm telescopic structure 401 is a bidirectional hydraulic rod. The pile position frames 402 are installed at the moving ends on both sides of the double-arm telescopic structure 401. The pile position frame 402 moves and is located inside the platform plate 102.

[0039] Specifically, in order to adjust the distance between pile positions in pile foundation construction, the double-arm telescopic structure 401 works, and the moving ends on both sides thereof respectively drive a group of pile position frames 402 to move, so that two groups of pile positions can be fixed at the same time, and the distance between the two groups of pile positions can be adjusted, and then the drilling machine drills holes in the foundation through the inside of the pile position frame 402.

[0040] An assembled pile foundation construction platform and pile foundation construction method according to the above, comprising the following steps: The three sets of main beams 101 are spliced ​​in an n-shape, and multiple sets of platform plates 102 are assembled between the three sets of main beams 101 by plugging inside the three sets of main beams 101. Then, the last set of main beams 101 is assembled on the missing side of the three sets of main beams 101. The main beams 101 are fixedly assembled by using rotating buckles 502 and fixing pins 503. The four groups of hydraulic rods 201 drive a group of supporting legs 202 to move respectively, and the horizontal position of the platform frame 1 is adjusted in conjunction with the level meter 6; By removing the sealing plate 104 at the corresponding position inside the pile position slot 103, the double-arm telescopic structure 401 drives the two groups of pile position frames 402 to move along the inside of the two groups of pile position slots 103 at the same time, so that the device can find the pile position according to the setting; A drilling machine is used to drill into the foundation through the pile frame 402 to form pile holes, and bored piles are cast in each pile hole.

[0041] Working principle: Before the construction of the prefabricated pile foundation of the water conservancy project, the three groups of main beams 101 are spliced, and then the fixing pin 503 is inserted into the inside of the two vertical groups of main beams 101, and then the rotating buckle 502 is rotated to make the rotating buckle 502 clamped on the fixing pin 503, and the two vertical groups of main beams 101 are assembled and fixed, and then multiple groups of platform plates 102 are assembled between the three groups of main beams 101 by plugging, and the last group of main beams 101 is fixed on one side of the notch of the three groups of main beams 101 in the same way, and then the sealing plate 104 at the corresponding drilling position is taken out, so that the double-arm telescopic structure 401 works to drive the two groups of pile position frames 402 to move along the inside of the two groups of pile position grooves 103 at the same time, so that the device finds the pile position according to the setting, and finally a drilling machine is used to drill into the foundation through the inside of the pile position frame 402 to form a pile hole, and bored cast-in-place piles are cast in each pile hole.

[0042] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
