In the construction engineering, the common use modes of the prestressed concrete pipe pile are three, namely pile foundation, composite foundation and foundation pit support. When applied to actual engineering, weak soil layers often exist around the pile body, for example: a foundation consisting of silt, mucky soil, earth fill or other high-pressure earth layers. The foundation often has engineering characteristics of high natural water content, low bearing capacity and the like, is easy to slide or solidify and subside under the action of load, and has serious influence on the safety and stability of the building. Under similar engineering geological conditions, the strength of the pipe pile is often difficult to exert, and the engineering economy of the pipe pile is affected by a soft soil layer and cannot be fully embodied. In the engineering, a post grouting mode is generally adopted to carry out secondary treatment on soft stratum around the pile foundation, but the construction technology is mainly aimed at a bored pile at present, and the construction technology is rarely related to the field of pipe piles. The main reason is that the pipe pile is usually driven in sections and connected into piles, and the construction process difference of pile foundations makes the grouting method of the filling pile difficult to be applied. In addition, the common tubular pile length is generally shaped in a prefabrication factory, is limited by the current connection mode, and is difficult to effectively realize by combining grouting at the pile side and the pile end of the tubular pile. Moreover, the distribution depth of the actual weak stratum is not opposite to the length of the pipe joint, and how to realize grouting at a specific depth or to realize grouting in the stratum which is not disclosed in the geological survey has no effective method, so that the quality and the efficiency of the development of the pipe pile grouting work in the actual engineering are affected.

Detailed Description
In order that the invention may be more readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Fig. 1 is a schematic structural diagram of an intelligent sounding pipe pile capable of realizing grouting at different depths according to an embodiment of the present application. The pile comprises a pile bottom pile section 1, a plurality of pile section pile sections 6, a pressure sensor 11, a data acquisition device 29 and a grouting device 12. The pile sections 6 are sequentially connected and then connected with the pile bottom pipe pile section 1 to form a pipe pile main body. The pressure sensor 11 is fixedly arranged in the pile bottom pipe pile joint 1 and is electrically connected with the data acquisition device 29. The grouting device 12 is used for grouting into the pipe pile.
Specifically, pile bottom tubular pile section 1 includes pile bottom tubular pile 2. The pile bottom pipe pile 2 is a prestressed concrete pile. An end plate 3 is fixedly arranged at the upper end of the pile bottom pipe pile 2. Three first grouting pipes 4 and three second grouting pipes 5 are fixedly arranged in the pile bottom pipe pile 2. The grouting openings at the upper ends of the first grouting pipe 4 and the second grouting pipe 5 are communicated with through holes formed in the end plate 3. The grout outlet at the lower end of the first grouting pipe 4 extends to the lower end of the pile bottom pipe pile 2. The axis of the first grouting pipe 4 is parallel to the axis of the pile bottom pipe pile 2. The grout outlet of the lower end of the second grouting pipe 5 extends to be communicated with the side wall of the pile bottom pipe pile 2.
Fig. 2 is a schematic cross-sectional view of a pile bottom tubular pile section 1. Wherein, three first slip casting pipes 4 and three second slip casting pipes 5 are annular and arrange, and the centre of a circle of place circumference is located the axis of stake end tubular pile festival 1. The first grouting pipe 4 and the second grouting pipe 5 are sequentially staggered.
A shoe 26 is fixedly installed at the lower end of the pile bottom pipe pile 2. The pressure sensor 11 is fixedly mounted in the shoe 26. The lower end of the pile shoe 26 is provided with an opening communicated with the grout outlet of the first grouting pipe 4. Grouting liquid 37 in the first grouting pipe 4 can enter the soil layer of the pile end through the opening, so that pile bottom grouting is realized.
The pile section tubular pile section 6 comprises a pile section tubular pile 7. The pile section pipe pile 7 is also a prestressed concrete pile. An upper end plate 8 and a lower end plate 9 are respectively fixedly arranged at the upper end and the lower end of the pile section pipe pile 7. Six third grouting pipes 10 are fixedly arranged in the pile section pipe pile 7. The grouting opening at the upper end of the third grouting pipe 10 is communicated with the through hole formed in the upper end plate 8, and the grouting opening at the lower end of the third grouting pipe 10 extends to the lower side of the lower end plate 9.
Fig. 6 is a schematic cross-sectional view of pile section tube 7. Six third grouting pipes 10 are arranged in an annular mode. The circle center of the circumference where the six third grouting pipes 10 are located is located on the axis of the pile section pipe pile 7, and the diameter of the circumference is equal to the diameters of the circumferences where the first grouting pipe 4 and the second grouting pipe are located. When the pile section pipe pile 7 joint 6 is in butt joint with the pile bottom pipe pile joint 1, six third grouting pipes 10 can be aligned with and communicated with the first grouting pipe 4 and the second grouting pipe 5 respectively.
A connecting device is fixedly arranged at the lower end of each pile section pipe pile joint 6 and is used for connecting the adjacent pile section pipe pile joints 6. Wherein the connecting device is arranged on a third grouting pipe 10 extending to the outside of the lower end plate 9 in each pile section pipe pile section 6. Referring to fig. 9, the connection means includes an upper fixing support 13 and a lower fixing support 14 fixedly installed on the third grouting pipe 10. The lower fixing support 14 is fixedly welded to the lower end of the third grouting pipe 10. Four hinge seats are fixedly provided at the side of the lower fixing support 14. Each hinge seat is hinged with a supporting rod 15. Each support bar 15 is connected to the upper fixed support 13 by an elastic support assembly. When the support rod 15 rotates around the hinge seat, the support rod 15 approaches to or departs from the upper fixed support 13, and in the process, the elastic supporting component can elastically deform and apply force to the support rod 15 to reset the support rod 15. A support plate 36 is fixedly connected to the upper end of the support rod 15. The upper end of each supporting plate 36 is fixedly provided with a connecting rod 34, the upper end of each connecting rod 34 is hinged with a transmission rod 16 through a hinge shaft 35, and the other end of each transmission rod 16 is hinged with a movable sleeve 17 which is sleeved outside the third grouting pipe 10 in a sliding manner. The movable sleeve 17 is located above the upper fixed support 13.
When an external force is applied to slide the movable sleeve 17 upward along the third grouting pipe 10, the transmission rod 16 and the connecting rod 34 drive the four support plates 36 to move toward the third grouting pipe 10, so that the distance between the support plates 36 and the third grouting pipe 10 is reduced, namely, the four support plates 36 simultaneously move inward. The support plate 36 moves and drives the support rod 15 to move towards the third grouting pipe 10, so that the elastic support assembly deforms. Referring to fig. 8, the lower part of the connecting device can extend into the grouting opening at the upper end of the third grouting pipe 10 in the pipe pile 7 joint 6 of the adjacent pile section. When the external force is removed, the elastic supporting component between the supporting rod 15 and the upper fixed support 13 can be reset, and drives the supporting rod 15 to rotate outwards, so that the supporting plate 36 is driven to be far away from the third grouting pipe 10, the distance between the supporting plate 36 and the third grouting pipe 10 is increased, namely, four supporting plates 36 simultaneously move outwards, the lower part of the connecting device can be spread in the grouting opening of the third grouting pipe 10 in the adjacent pile section pipe pile section 6, and the connection between the adjacent pile section pipe pile sections 6 is realized.
Referring to fig. 10, the elastic support assembly includes a first connecting rod 18, a second connecting rod 19, and two snap discs 20. One end of the first connecting rod 18 is hinged with the inner side of the adjacent supporting rod 15, and the other end of the first connecting rod 18 is fixedly connected with a clamping disc 20. One end of the second connecting rod 19 is hinged on the upper fixed support 13, and the other end of the second connecting rod 19 is fixedly connected with the other clamping disc 20. The two catch discs 20 are arranged opposite each other and are connected by a rotation shaft 21. The rotation shaft 21 coincides with the axes of the two catch discs 20, and both ends of the rotation shaft 21 are rotatably mounted on the two catch discs 20, respectively. A spring 22 is sleeved outside the rotating shaft 21, and two ends of the spring 22 are fixedly connected with the two buckling discs 20 respectively.
When the support rod 15 moves toward the third grouting pipe 10, the two catch disks 20 are reversely rotated, so that the spring 22 between the two catch disks 20 is tightened, and the spring 22 generates elastic force. When the external force is removed, the spring 22 is restored, and the generated elastic force makes the two catch discs 20 reversely rotate, so that the upper end of the support rod 15 gradually gets away from the third grouting pipe 10.
Wherein, a rotating wheel 33 is rotatably installed at a hinge point where the connecting rod 34 and the transmission rod 16 are hinged to each other, and a hinge shaft 35 is penetrated at an axis of the rotating wheel 33, so that the rotating wheel 33 can rotate around the hinge shaft 35, as shown in fig. 11.
