DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Embodiment 1: like Figure 1 and Figure 2 As shown, a construction method of a water suspended cap pile head clamp system comprises the following steps: S1. Locate the point where piles need to be sunk, and hammer the piles at the located points; Specifically, the pile head treatment construction can be started when the working surface meets the construction requirements and has no impact on other work. For piles that are higher than the design elevation, first use a level to copy the design elevation position, pop out a black line along the pile circle on the design elevation position line, and use a marble saw to saw the pile along the popped-out line. The pile sawing is carried out twice, and the pile head is firmly tied to the gantry crane with a sling. After cutting, the gantry crane is used to lift the cut pile head from its original position to the shore. After docking, the truck crane prepared on the shore is used to lift the pile head to the transport vehicle and transport it to the designated yard.

[0024] S2, installing a clamp 2 on the pile 1 that has been completed; S3, installing a steel beam 3 on the hoop 2 and the pipe pile 1, connecting the multiple pipe piles 1 together through the steel beam 3, installing a template on the steel beam 3 and tying steel bars; S4. Pour concrete on the formwork and the tied steel bars; S5. After the concrete strength meets the requirements, remove the formwork and complete the construction.

[0025] After the pipe pile 1 is sunk, the suspended formwork can be installed immediately to achieve rapid positioning and fixing, reducing the complex processes in the traditional construction method, thereby improving construction efficiency. Using the pipe pile 1 as the foundation can provide good bearing capacity and stability to ensure the long-term safety of the concrete platform. In an aquatic environment, a stable formwork system can be built without solid ground support to achieve the pouring construction of the concrete platform, while reducing the requirements for underwater foundation treatment and the difficulty of construction. The suspended construction on water avoids large-scale foundation excavation, replacement and concrete foundation pouring, reduces a lot of noise pollution to surrounding residents, and has little impact on the surrounding environment.

[0026] The present invention solves the problems of existing foundation excavation and concrete pouring, which are easy to pollute the surrounding environment, require large-scale foundation excavation, and avoid the need to set up full-house scaffolding; and the economic losses caused by large-scale drainage and emptying of fish ponds during construction. After the formwork is quickly installed using the pile head clamp 2, the construction period is greatly shortened, the use of manpower and material resources is reduced, the construction efficiency is high, and the construction quality of the suspended platform is guaranteed.

[0027] Preferably, the pipe pile 1 is a prestressed high-strength concrete pipe pile 1.

[0028] Specifically, the prestressed high-strength concrete pipe pile 1 is a PHC pipe pile, and the template is an above-water high-cap suspended template. The above-water high-cap suspended template utilizes the PHC (prestressed high-strength concrete) pipe pile with high strength, high durability and good bearing performance, and is suitable for foundation construction in an aquatic environment. The vertical bearing capacity and stability of the PHC pipe pile are used as the basis of the supporting structure, and the pipe pile 1 can provide reliable vertical support by being driven into the underwater stratum.

[0029] Preferably, the pile driving is controlled by penetration.

[0030] Preferably, the depth of the full cross section of the pile end of the pipe pile 1 (excluding the pile tip) into the strongly weathered rock is not less than 0.8m, and the depth of the weathered layer is not less than 0.2m. The stop hammer standard of the PHC pipe pile is: the final penetration (average value of 10 hits) should be controlled at 5-10mm.

[0031] Specifically, the construction is carried out in accordance with this standard to ensure that the quality of pile driving meets the construction requirements. During construction, when the pile driving reaches the design elevation, the penetration is controlled above the upper limit, and when the pile driving does not reach the design elevation, the penetration is controlled below the lower limit. If the top of the pile has reached the design elevation and the penetration is still large, the pile should continue to be driven until the penetration is or approaches the penetration control standard. Under normal circumstances, the pile 1 is stopped when it is 50-80cm into the soil, and then the verticality is adjusted. A dedicated person is assigned to monitor the verticality using two theodolites (a plumb bob can also be used for observation). The theodolites should be set at a place that is not affected by the pile driving (about 20 meters away from the pile point) and in a direction approximately 90° to each other. They should be leveled frequently to monitor the verticality of the guide frame, and the adjustment should be made by sliding and stopping the guide frame of the pile driver.
