[0034] The outer diameter of the steel pipes of the horizontal steel pipes and the vertical steel pipes is 42.2 - 48.3 mm, and the wall thickness of the steel pipes is 3.56 - 5.08 mm. Preferably, the specification model of the steel pipe is Φ48.3*3.68.

[0035] The pipe clamp 3 includes a first arc-shaped plate 31 and a second arc-shaped plate 32. First vertical plates 33 are welded to both ends of the first arc-shaped plate 31, and second vertical plates 34 are welded to both ends of the second arc-shaped plate. Bolt holes for connecting bolts are provided on the first vertical plates 33 and the second vertical plates 34. The thickness of the arc-shaped plates and the vertical plates is 6 - 10 mm, and the distance from the center of the bolt hole to the edge of the vertical plate shall not be less than 1.5 - 2 times the bolt diameter.

[0036] The first arc-shaped plate 31 and the second arc-shaped plate 32 have the same radius, and the openings of the first arc-shaped plate 31 and the second arc-shaped plate 32 are opposite to each other.

[0037] The first vertical plates 33 and the second vertical plates 34 at the same end are connected by bolts. The number of bolts used to connect the first arc-shaped plate 31 and the second arc-shaped plate 32 at each end is 2. The distance between the bolts is 200 - 250 mm. The bolts pass through the vertical plates and are connected with nut washers. The nut washers are on the same side.

[0038] Rubber gaskets are provided on the inner walls of the first arc-shaped plate 31 and the second arc-shaped plate 32.

The material of the pipe clamp 3 has sufficient strength and hardness to bear the weight of the pipeline and external pressure. The pipe clamp 3 shall provide sufficient clamping force to ensure that the pipeline will not slide or loosen during use. Using rubber gaskets can increase the friction force and prevent the pipeline from sliding.

[0039] The fixed support 2 is composed of 4 steel pipes. The 4 steel pipes are vertically crossed and closely attached to the outer wall of the pipe support 5. The fixed support 2 is convenient to adjust and can be adjusted according to the different sizes of the pipe support 5 to ensure the accurate positioning of the pipe support 5 in the X and Y directions.

[0040] Fasteners 4 are provided at the joints between the steel pipes of the fixed support 2 and at the joints between the fixed support 2 and the support frame 1.

[0041] Fasteners 4 are provided at the joints between the horizontal steel pipes of the support frame 1 and at the joints between the horizontal steel pipes and the vertical steel pipes.

[0042] The support frame 1 and the fixed support 2 are made of A53B material, and the pipe clamp 3 is made of A36 material. The specifications are selected according to the size of the pipe support 5. When the pipe clamp 3 is used to bear the self-weight of the pipe support 5, the specifications shall be determined according to twice the calculated load.

[0043] This utility model is designed based on the weight and specifications of the cast-in-place pile pipe supports in the EPC project of the second phase of the Lumut Balai geothermal power station in Indonesia. The material of the directly buried pipe support 5 is A53B. The maximum designed pipe specification is Φ406.4*21.44, with a length of 2.1 m and a maximum weight of 427.4 KG. Therefore, the selected pipe clamp 3 should be able to withstand a load of at least 854.8 KG. The pipe clamp 3 should be subjected to a stress test before use to ensure that the pipe does not slide after fastening, thus ensuring the accuracy of the elevation. The tool raw materials can be used only after meeting the above requirements.

[0044] After the cast-in-place pile is drilled and the steel reinforcement cage is in place, place the reinforcement tool for the directly buried pile foundation support provided by this utility model on the upper part of the cast-in-place pile. Subsequently, use a crane to slowly hoist the pipe support 5 into the cast-in-place pile borehole, and preliminarily adjust and fix the support 2 according to the specifications of the pipe support 5. After measuring and confirming the elevation, fasten the support 2 and the pipe clamp 3 to the pipe support 5, and then unhook for pouring.

[0045] When using the reinforcement tool for the directly buried pile foundation support, it is necessary to comprehensively consider the actual weight and specifications of the pipe support 5. If necessary, weld a fixture block on the pipe support 5 and support it on the pipe clamp 3 to prevent the pipe from sinking.
