[0028] Working principle:
[0029] First step, construction preparation
[0030] In use, the worker can first preset the reinforced concrete pipe on the foundation 11 according to the normal flow of the river and the flood discharge capacity in flood season, and backfill the river island according to the position of the cast-in-place pile body 13, then the worker can re-measure the construction surface of the foundation 11 and perform measurement and lofting, then two control piles can be introduced on each side in the longitudinal and transverse directions, the distance between the two control piles is 2 meters, which is used to control the axis deviation during drilling, after the control piles are introduced, the cross line is pulled, and the drill bit is adjusted to the center of the cross line by the line hammer, then the worker can install the temporary casing 15 at the ring groove 14 according to the four ends of the cross line.
[0031] Second step, pile foundation hole forming;
[0032] According to different geological conditions, select economic and reasonable pile foundation construction machinery, according to the design requirements to form the hole of the pile foundation, after the hole is formed, the drill bit is raised 10-20 cm from the bottom of the hole, and the slow rotation is maintained, the circulating hole cleaning time is maintained for not less than 30 minutes, the mud with good performance is used, the specific gravity and viscosity of the mud are controlled, and the water is not used for replacement, when the reinforcement cage is hoisted, the center of the reinforcement cage is kept consistent with the center of the pile to avoid collision with the hole wall, the cold pressure joint process of the reinforcement cage can be used to speed up the butt joint of the reinforcement cage, reduce the empty hole time, and thus reduce the sediment, after the reinforcement cage is lowered, the sediment amount is checked, if the sediment amount exceeds the specification requirement, the second hole cleaning is performed by using the guide pipe until the hole opening returns to the mud specific gravity and the sediment thickness meet the specification requirements, thereby completing the hole forming of the pile foundation, and further forming the cast-in-place pile body 13 and the reinforcement group 21.
[0033] Third step, finishing work;
[0034] After the pile foundation construction is completed, the soil cofferdam should be removed to the river bottom elevation, then the worker can sleeve the permanent casing 16 outside the cast-in-place pile body 13, at the same time, the worker can perform rust removal treatment on the permanent casing 16 exposed above the foundation 11, immediately perform waterproof and rust-proof paint brushing after the rust removal, ensure the ornamental nature of the appearance of the exposed part of the pile foundation, then the worker can take the detachable casing 19, and insert the clamping block 18 on the detachable casing 19 into the installation slot 17, then insert the first through slot 24 and the second through slot 25 on the first square plate 22 and the second square plate 23 inside the detachable casing 19 into the reinforcement group 21 on the cast-in-place pile body 13, and the installation is completed, at the same time, after the concrete above the cast-in-place pile body 13 reaches the initial setting state, the upper detachable casing 19 is removed, and the floating slurry of the pile head is broken.
[0035] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived from it are still within the protection scope of the utility model.
