[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. The directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the accompanying drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution. The "first, second..." used are only used to distinguish the names and do not represent specific quantities and orders.

[0035] like Figures 1 to 3As shown, the utility model provides a pressure stabilizing pile sealing device, which includes a reaction force assembly 1, a pile sealing rod 2, a first fastener 3, a prestressed pipe pile 4 and a concrete member 5. The reaction force assembly 1 includes a first reaction frame 6, a jack 7 and a second reaction frame 8. The jack 7 is arranged between the first reaction frame 6 and the second reaction frame 8. The first reaction frame 6 and the second reaction frame 8 are both made of channel steel, and their shapes are preferably square, so as to better support the jack 7 and apply reaction force to the prestressed pipe pile 4. The first reaction frame 6 and the second reaction frame 8 are both provided with through holes, and the pile sealing rod 2 is arranged in the through holes. The reaction force assembly 1 can move along the direction of the pile sealing rod 2. Specifically, one end of the pile sealing rod 2 is exposed on the first reaction frame 6, and the other end of the pile sealing rod 2 can be buried in the original newly added raft foundation. When the original foundation is seriously damaged, a newly added raft foundation 15 can be newly built, and the other end of the pile sealing rod 2 is connected to the steel bars of the newly added raft foundation 15. The first fastener 3 is arranged above the first reaction frame 6 and connected to the pile sealing rod 2. The prestressed pipe pile 4 is arranged below the second reaction frame 8. When the jack 7 is working, the first reaction frame 6 cannot move upward along the pile sealing rod 2 through the fastener, thereby playing a supporting role. The second reaction frame 8 moves downward along the pile sealing rod 2 as the jack 7 works, thereby applying a reaction force to the prestressed pipe pile 4, so that the prestressed pipe pile 4 is buried in the newly added raft foundation 15 and the foundation, and can transfer the load of the existing building superstructure to the foundation, thereby increasing the foundation bearing capacity of the existing building. Since there will be gaps around the prestressed pipe pile 4 buried in the newly added raft foundation 15 and the foundation, which will affect its overall stability, concrete pieces 5 are used to fill the prestressed pipe pile 4. For concrete mixed with expansion agent, the cement dosage should not be less than 320Kg / m3. For concrete in a weak erosion or medium erosion environment, the cement dosage should not be less than 360Kg / m3. The above-mentioned pressure-stabilizing pile sealing device can better cooperate with the original foundation of the building, thereby achieving a better effect of controlling the settlement of the building.

[0036] In a specific embodiment, Figures 4 to 6 As shown, the prestressed pipe pile 4 includes a first prestressed pipe pile 9 and a second prestressed pipe pile 10. The first prestressed pipe pile 9 and the second prestressed pipe pile 10 are detachably connected, so that the number of prestressed pipe piles 4 can be used according to the actual needs on site, avoiding the need for manual cutting due to the prestressed pipe pile 4 being too long. More specifically, a connecting pin is provided at the lower end of the first prestressed pipe pile 9, and a connecting groove 11 is provided at the upper end of the second prestressed pipe pile. The connecting pin acts on the connecting groove 11. The connecting groove 11 has a steel pin plate 12 and a spring 13, and the steel pin plate 12 is connected to the spring 13. The steel pin plates 12 on both sides of the connecting groove 11 are squeezed to compress the spring 13, so as to facilitate the adaptation of connecting pins of different volumes. In addition, in order to further ensure the stability of the connecting pin in the connecting groove 11, a tooth pattern 18 is provided on the steel pin plate 12.

[0037] In a specific embodiment, the pressure-stabilizing pile sealing device further includes a steel pipe 14, which is connected to the prestressed pipe pile 4. By providing the steel pipe 14, the second reaction frame 8 directly acts on the steel pipe 14, which can not only transmit pressure to the prestressed pipe pile 4 to avoid damage to the prestressed pipe pile 4, but also the steel pipe 14 with greater hardness can further increase the bearing capacity of the foundation.

[0038] In a specific embodiment, Figures 7 to 9 As shown, since the columnar prestressed pipe pile 4 needs to be subjected to greater force when inserted into the newly added raft foundation 15 and the foundation, an end cap 17 is provided at the lower end of the second prestressed pipe pile 10. More specifically, the shape of the end cap 17 is a flat-bottomed cross, a pointed-bottomed cross or a quadrangular pyramid. With the action of the end cap 17, the prestressed pipe pile 4 can be inserted into the newly added raft foundation 15 and the foundation more quickly and labor-savingly.

[0039] In a specific embodiment, a bolt hole 19 is provided at the upper end of the first prestressed pipe pile 9, and the steel pipe 14 is detachably connected to the prestressed pipe pile 4 through the bolt hole 19, which not only ensures the firmness of the steel pipe 14 and the prestressed pipe pile 4, but also facilitates on-site installation by construction personnel.

[0040] In a specific embodiment, after the steel pipe 14 and the prestressed pipe piles 4 are inserted into the newly added raft foundation 15 and the foundation and filled with concrete parts, in order to ensure their stability and prevent the steel pipe 14 and the prestressed pipe piles 4 from rebounding, the pressure-stabilizing pile sealing device is provided through the second fastener 16. The second fastener 16 is arranged above the second reaction frame 8 and is connected to the pile sealing rod 2, thereby preventing the second reaction frame 8 from moving upward along the pile sealing rod 2.

[0041] In a specific embodiment, in order to save costs, the pile sealing rod 2 adopts a screw rod, and the first fastener 3 and the second fastener 16 are both composed of a nut and a pad. With the cooperation of the screw rod and the nut, the first reaction frame 6 and the second reaction frame 8 can be locked, and the pad can increase the contact area with the first reaction frame 6 and the second reaction frame 8, so as to better lock the first reaction frame 6 and the second reaction frame 8. More specifically, the number of screw rods is preferably four. After the steel pipe 14 and the prestressed pipe pile 4 are stabilized, the counter-assembly is removed, and the four screw rods are exposed on the newly added raft foundation 15. The four screw rods are folded and cast along the diagonal direction to form a composite plate, thereby further improving the bearing capacity of the foundation.

[0042] The use principle of the utility model is as follows: the jack 7 is arranged between the first reaction frame 6 and the second reaction frame 8, the first reaction frame 6 and the second reaction frame 8 are both provided with through holes, the pile sealing rod 2 is arranged in the through hole, the reaction assembly 1 can move along the direction of the pile sealing rod 2, one end of the pile sealing rod 2 is exposed on the first reaction frame 6, the pile sealing rod 2 adopts screw rods and there are four of them, the other end of the pile sealing rod 2 can be buried in the original newly added raft foundation, when the original newly added raft foundation is seriously damaged, a new newly added raft foundation 15 can be built, and the other end of the pile sealing rod 2 is connected to the steel bars of the newly added raft foundation 15. The first fastener 3 is composed of a nut and a pad. The first fastener 3 is arranged above the first reaction frame 6 and connected to the pile sealing rod 2. The prestressed pipe pile 4 is arranged below the second reaction frame 8. When the jack 7 is working, the first reaction frame 6 cannot move upward along the pile sealing rod 2 through the fastener, thereby playing a supporting role. The second reaction frame 8 moves downward along the pile sealing rod 2 as the jack 7 works, thereby applying a reaction force to the prestressed pipe pile 4, so that the prestressed pipe pile 4 is buried in the newly added raft foundation 15 and the foundation, and can transfer the existing building superstructure load to the foundation, thereby increasing the foundation bearing capacity of the existing building. Concrete parts 5 are used to fill the surroundings of the prestressed pipe pile 4. After the steel pipe 14 and the prestressed pipe pile 4 are stable, the reaction assembly 1 is removed, and the four screws are folded and cast along the diagonal direction to form a composite plate, which can further improve the bearing capacity of the foundation. Therefore, the above-mentioned pressure-stabilizing pile sealing device can better work together with the original foundation of the building, thereby achieving a better effect of controlling the settlement of the building.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
