Description

TECHNICAL FIELD

[0001] The present application relates to the field of building pipe pile and its construction technology, and particularly relates to a pipe pile system and a construction method thereof. BACKGROUND

[0002] The building pipe pile can be generally prefabricated by reinforced concrete, and after curing, the construction can be carried out. The pipe pile in the prior art is generally of a tubular structure, and the multiple sections can be connected with each other to be inserted into a deeper part of the foundation. Specifically, during construction, the hole is first drilled, and then the pipe piles are sequentially placed into the hole to be connected with each other. In the actual construction process, the pipe pile at the deepest part directly abuts against the inner bottom surface of the hole. Generally, the hole is slightly larger to facilitate the pipe pile to be placed into the hole. Therefore, in the process of placing the subsequent pipe pile (i.e., the pipe pile above the pipe pile at the deepest part) into the hole, the pipe pile is easily deviated, and finally the pipe pile assembly after construction deviates from the requirement. SUMMARY

[0003] In view of the deficiencies in the prior art, the present application provides a pipe pile system and a construction method thereof, which solve the problem that the pipe pile assembly after construction is easily deviated from the requirement due to deviation.

[0005] Further, the first pipe pile section is filled with concrete, and the hammering part has a connecting end opposite to the hammering end, and the connecting end is wrapped by the concrete.

[0006] Further, the connecting end is columnar, and one end of the connecting end away from the hammering part is in the shape of a spherical cap.

[0010] Further, the hammering part has a tapered surface, and the inner wall of the sleeve is fixedly connected with a limiting ring capable of abutting against the tapered surface.

[0011] Further, the first pipe pile section is fixedly provided with a second connecting ring at one end away from the sleeve, and the second pipe pile section is also fixedly provided with a second connecting ring at one end and a second sleeve ring sleeved with the second connecting ring at the other end.

[0012] According to the embodiments of the present application, the present application also provides a construction method of the above-mentioned pipe pile system, which comprises the following steps: opening a hole in a foundation, connecting the first pipe pile section and the hammering-in section and then loading them into the hole, filling the first pipe pile section with concrete and vibrating and tamping the first pipe pile section to make the hammering-in part descend to the lowest position, and then loading all the second pipe pile sections in sequence.

[0023] As Figure 1 , 2 , 3, 4, the embodiment provides a pipe pile system, which comprises a first pipe pile section 1 and a plurality of second pipe pile sections 2, one end of the first pipe pile section 1 is sleeved with one of the second pipe pile sections 2, and the other end is sleeved with a hammering section 3, the second pipe pile sections 2 are sleeved with each other, so as to form an overall pipe pile system comprising one first pipe pile section 1 and a plurality of second pipe pile sections 2; wherein the hammering section 3 comprises a sleeve 4 and a hammering part 5 in sliding contact with the inner wall of the sleeve 4, the hammering part 5 has a hammering end 6 away from the second pipe pile section 2, and the hammering end 6 can extend out of the sleeve 4 with the sliding of the hammering part 5 and the sleeve 4; wherein the first pipe pile section 1 and the second pipe pile section 2 are provided, which are similar to the pipe pile in the prior art, the difference lies in that the hammering section 3 is connected with one end of the first pipe pile section 1 during construction, then the hammering end 6 of the hammering part 5 is extended downward into the bottom of the hole 15 (the hole 15 is opened in the foundation 7), and the hammering end 6 is penetrated into the inner bottom surface of the hole 15 by the concrete 8 before the construction of the second pipe pile section 2, so that the lower end of the first pipe pile section 1 is more stable, and the subsequent construction of the second pipe pile section 2 is less likely to deviate, so that the construction of the pipe pile system is more stable, and the problem that the pipe pile assembly in the prior art is easy to deviate after construction, resulting in deviation from the construction requirements, is solved.

[0024] Preferably, the first pipe pile section 1 is filled with concrete 8, the hammering part 5 has a connecting end 9 opposite to the hammering end 6, and the connecting end 9 is wrapped by the concrete 8, that is, the concrete 8 makes the hammering part 5 slide down in the sleeve 4, and then the hammering end 6 is driven into the bottom surface of the hole 15, and at this time, the concrete 8 also enters the sleeve 4 to fill the space left by the downward movement of the hammering part 5, so that the hammering part 5, the sleeve 4 and the first pipe pile section 1 form a more stable whole, and the stability of the first pipe pile section 1 is further improved. In particular, the connecting end 9 is columnar, and the end of the connecting end 9 away from the hammering part 5 is in the shape of a spherical cap. When the concrete 8 is filled, the concrete 8 can first wrap the connecting end 9 to form a whole and apply a pushing force to the entire hammering part 5 to make the hammering part 5 slide down, and finally the hammering end 6 is driven into the bottom surface of the hole 15. The end of the connecting end 9 in the shape of a spherical cap can divert the concrete 8 to the four sides, so that the surrounding concrete 8 is evenly distributed, thereby smoothly applying a pushing force to make the hammering part 5 slide down.

[0025] Preferably, when the hammering end 6 is outside the sleeve 4, the connecting end 9 is located inside the sleeve 4 and the first pipe pile section 1 respectively, that is, after the hammering end 6 is driven into the bottom surface of the hole 15 by the concrete 8, the connecting end 9 spans the sleeve 4 and the first pipe pile section 1, and also wraps the concrete 8 to make the connection at this part integral.

[0026] Preferably, one end of the sleeve 4 is fixedly connected with a first connecting ring 10, one end of the first pipe pile section 1 is fixedly provided with a first sleeve ring 11, and the first connecting ring 10 is sleeved outside the first sleeve ring 11. Through the cooperation of the first connecting ring 10 and the first sleeve ring 11, the first pipe pile section 1 and the hammering section 3 are sleeved together. Further, the end surface of the first sleeve ring 11 away from the first pipe pile section 1 abuts against the end surface of the sleeve 4 connected with the first connecting ring 10, so that the sleeve connection between the first pipe pile section 1 and the sleeve 4 is stable. When the concrete 8 is filled, the first sleeve ring 11 on the sleeve 4 and the first pipe pile section 1 abut tightly together, and the concrete 8 is not easy to leak out at this connection.

[0027] Preferably, the hammering part 5 has a tapered surface, and a limiting ring 12 capable of abutting against the tapered surface is fixedly connected to the inner wall of the sleeve 4, so that the hammering part 5 cannot be separated from the sleeve 4. Further, the inner diameter of the sleeve 4 is greater than the inner diameter of the first pipe pile section 1, and they are coaxially arranged, so that the hammering part 5 cannot be separated from the upper end of the sleeve 4 after the sleeve 4 and the first pipe pile section 1 are connected. Further, the hammering part 5 and the sleeve 4 are in sliding contact. With the entry of the concrete 8 and the subsequent vibration compaction, the hammering part 5 slides downward under pressure, and then drives the hammering end 6 into the bottom surface of the hole 15. The tapered surface of the hammering end 6 makes the end of the hammering end 6 pointed, which can be more easily driven into the hole. Further, the end of the hammering end 6 can be directly provided in the shape of a spike.

[0028] Preferably, the first pipe pile section 1 is fixedly provided with a second connecting ring 13 at one end away from the sleeve 4, and the second pipe pile section 2 is fixedly provided with a second sleeve ring 14 sleeved with the second connecting ring 13 at one end and also provided with a second connecting ring 13 at the other end, i.e. through the cooperation between the second connecting ring 13 and the second sleeve ring 14, the second pipe pile section 2 and the first pipe pile section 1 are sleeved, and the second pipe pile sections 2 are also sleeved.

[0029] In particular, in the embodiment, the hammering part 5 is in sliding contact with the sleeve 4 but not in a sealed state, and the hammering part 5 can be smoothly lowered by vibration compaction.

[0030] In another embodiment, the application also provides a construction method of the above pipe pile system, which comprises the following steps: opening a hole 15 in the foundation 7, connecting the first pipe pile section 1 and the hammering section 3 and then loading them into the hole 15, then filling the first pipe pile section 1 with concrete 8 and performing vibration compaction, so that the hammering part 5 is lowered to the lowest position, and then loading all the second pipe pile sections 2 in sequence, wherein the first pipe pile section 1 is located at a deeper position, so that the concrete 8 can be sent in by using a pump pipe, and then vibration compaction is performed by using a vibration rod; specifically, the first pipe pile section 1 and the hammering section 3 are placed first, and then the first concrete 8 is poured, and then the hammering part 5 of the hammering section 3 is slid downward by vibration compaction, so that the hammering end 6 is driven into the bottom surface of the hole 15, and at the same time, the hammering section 3 and the first pipe pile section 1 are poured into a more stable overall structure by the concrete 8, and the overall structure is positioned by the hammering end 6, so as to prevent deviation during subsequent construction, and then the subsequent second pipe pile sections 2 are loaded, and after all the second pipe pile sections 2 are loaded, the second concrete 8 is poured, so that the entire pipe pile system forms a larger overall structure, thereby improving the overall mechanical properties.

[0031] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the application but not limit the application, and although the application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the application can be modified or replaced equivalently without departing from the purpose and scope of the application, and all of them should be covered in the scope of the claims of the application.
