Description

Technical Field

[0001] This utility model relates to the field of static pressure pile technology, specifically a static pressure pile with synchronous grouting and synchronous pressing for pile driving. Background Technology

[0002] Static pressure piling is a method of engineering pile foundation construction. It involves using a static pile driver, with the machine's own weight and counterweights on its frame providing pressure, to drive precast piles into the soil. Because static pressure piling does not use a hammer, it completely avoids the vibration, noise, and pollution caused by hammer driving. Static pressure piling causes less damage to the pile body, ensuring its integrity and stability. It also allows for faster construction, effectively shortening the construction period and reducing project costs. Furthermore, it reduces safety risks for construction workers.

[0003] When driving static pressure piles, the static pressure pile body needs to be fixed to the ground. After the static pressure pile body is fixed to the ground, it is necessary to continue driving by connecting static pressure piles. When connecting static pressure piles to the static pressure pile body, the connection position of the two static pressure piles needs to be welded. However, due to the lack of a positioning mechanism, gaps are easily generated at the connection position during the welding process, resulting in an insufficiently strong weld. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a static pressure pile for simultaneous grouting and driving, comprising a static pressure pile body, a pile head fixedly connected to the bottom of the static pressure pile body, a grout outlet hole on the surface of the static pressure pile body, a grout inlet hole on the top of the static pressure pile body, a limiting groove inside the static pressure pile body, a locking platform inside the limiting groove, a limiting column fixedly connected to the top of the locking platform, a connecting static pressure pile fixedly connected to the top of the limiting column, a second grout outlet hole on the top of the connecting static pressure pile, a second grout inlet hole on the surface of the connecting static pressure pile, and a second limiting groove inside the connecting static pressure pile.

[0005] Through the above technical solution, by setting up a clamping platform, the static pressure pile body is connected to the connecting static pressure pile during static pressure pile driving. This allows the clamping column to be installed inside the static pressure pile body, and the top of the static pressure pile body is connected to the bottom of the connecting static pressure pile, ensuring that the static pressure pile body and the connecting static pressure pile are concentric when the whole connection is made, while also facilitating synchronous grouting.

[0006] As a further improvement to the above scheme, the number of grout outlet holes is set to several, and the several grout outlet holes are evenly distributed on the surface with the center of the front of the static pressure pile body symmetrical.

[0007] With the above technical solution, several grout outlet holes are symmetrically and evenly distributed on the surface of the static pressure pile body. This design can ensure that during the grouting process, the grout can seep out evenly from around the static pressure pile body, so that the soil around the static pressure pile can be evenly reinforced and filled, thereby improving the stability and bearing capacity of the static pressure pile.

[0008] As a further improvement to the above scheme, the grout outlet hole penetrates the inner wall of the static pressure pile body.

[0009] With the above technical solution, the grout outlet hole penetrates the inner wall of the static pressure pile body. This design ensures that the grout can flow smoothly from the inside of the static pressure pile body to the soil outside that needs to be reinforced, avoiding uneven or incomplete grouting caused by the grout outlet hole being blocked, which is conducive to improving the quality of static pressure pile construction.

[0010] As a further improvement to the above solution, two card platforms are provided, and the two card platforms are evenly distributed on the surface with respect to the center of the bottom of the limiting post.

[0011] With the above technical solution, the two clamping platforms are symmetrically and evenly distributed on the surface with respect to the center of the bottom of the limiting column. This symmetrical distribution helps the clamping platforms to evenly bear the pressure and tension from the connected static pressure piles when connecting them, ensuring the stability of the connection and thus ensuring the structural stability of the entire static pressure pile during the pressing and use process.

[0012] As a further improvement to the above scheme, the limiting post is set inside the static pressure pile body, and the limiting post is concentric with the static pressure pile body.

[0013] With the above technical solution, the limiting column is set inside the static pressure pile body and is concentric with the static pressure pile body. This design enables the static pressure pile to maintain central symmetry when connecting other components, such as connecting other static pressure piles, avoiding additional stress caused by eccentricity, ensuring the verticality and stability of the static pressure pile during the pressing process, and improving construction accuracy.

[0014] As a further improvement to the above scheme, the diameter of the connecting static pressure pile is the same as the diameter of the static pressure pile body.

[0015] With the above technical solution, the diameter of the connecting static pressure pile is the same as the diameter of the static pressure pile body. This design helps to maintain the overall shape consistency of the static pressure pile during connection, so that the soil resistance experienced by the connected static pressure pile during the pressing process is evenly distributed, avoiding local stress concentration caused by diameter changes, thereby improving the overall performance of the static pressure pile.

[0016] As a further improvement to the above scheme, the number of the second grout outlet holes is set to several, and the several second grout outlet holes are evenly distributed on the surface in a symmetrical manner with respect to the front center of the static pressure pile. The second grout inlet hole has the same diameter as the first grout outlet hole.

[0017] As a further improvement to the above solution, the second slurry inlet hole penetrates the bottom of the limiting column.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model, by setting up a clamping platform, connects the static pressure pile body to the connecting static pressure pile during static pressure pile driving. This allows the clamping platform to be installed inside the static pressure pile body, with the top of the static pressure pile body connected to the bottom of the connecting static pressure pile. This ensures that the static pressure pile body and the connecting static pressure pile are concentric during the overall connection, and also facilitates synchronous grouting.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example 1:

[0028] Please combine Figure 1-5This embodiment of a static pressure pile for synchronous grouting and driving includes a static pressure pile body 1, a pile head 2 fixedly connected to the bottom of the static pressure pile body 1, the pile head 2 at the bottom helps the static pressure pile to better contact the foundation and transmit pressure during construction, a grout outlet hole 3 is opened on the surface of the static pressure pile body 1, a grout inlet hole 4 is opened on the top of the static pressure pile body 1, a limiting groove 5 is opened inside the static pressure pile body 1, a locking platform 6 is locked inside the limiting groove 5, a limiting column 7 is fixedly connected to the top of the locking platform 6, and a connecting static pressure pile 8 is fixedly connected to the top of the limiting column 7. The structural design of the limiting groove 5, the locking platform 6, the limiting column 7 and the connecting static pressure pile 8 makes it easy to connect the static pressure piles when the length needs to be increased. A second grout outlet hole 9 is opened on the top of the connecting static pressure pile 8, and grouting work can be easily connected to the grout outlet hole 3 through the grout outlet hole 9. A second grout inlet hole 10 is opened on the surface of the connecting static pressure pile 8, and a second limiting groove 11 is opened inside the connecting static pressure pile 8.

[0029] The number of grout outlet holes 3 is set to a certain extent, and the number of grout outlet holes 3 is evenly distributed on the surface of the front of the static pressure pile body 1 in a symmetrical manner.

[0030] The grout outlet hole 3 penetrates the inner wall of the static pressure pile body 1.

[0031] There are two card holders 6, which are evenly distributed on the surface symmetrically around the bottom center of the limiting post 7.

[0032] The limiting post 7 is set inside the static pressure pile body 1, and the limiting post 7 is concentric with the static pressure pile body 1.

[0033] The diameter of the connecting static pressure pile 8 is the same as the diameter of the static pressure pile body 1.

[0034] The number of grout outlet holes 2 9 is set to be several. The several grout outlet holes 2 9 are evenly distributed on the surface with the center of the front of the connecting static pressure pile 8 symmetrically. The diameter of the grout inlet hole 2 10 is the same as that of the grout outlet hole 1 3, so that the flow speed and flow rate of the grout between the static pressure pile body 1 and the connecting static pressure pile 8 can be kept relatively consistent during the grouting process, ensuring the uniformity and stability of the entire grouting process.

[0035] The second grout inlet hole 10 penetrates the bottom of the limiting column 7, ensuring that the grout can smoothly enter the bottom of the limiting column 7 from the connecting static pressure pile 8 and then flow into the static pressure pile body 1. This ensures the continuity of grouting and avoids dead zones or insufficient grouting, which helps to improve the grouting effect and overall performance of the static pressure pile.

[0036] The implementation principle of a static pressure pile with synchronous grouting and synchronous pressing in this embodiment is as follows: When driving a static pressure pile, the pile head 2 is first fixed in a designated position by a pile driver, and the pile is driven by the pile driver. Grouting is carried out through the grout inlet hole 4 and grout is discharged through the grout outlet hole 3 to ensure that grouting can be carried out synchronously during pile driving. After the static pressure pile body 1 is driven, the connecting static pressure pile 8 is lifted by a crane. Then, the clamping platform 6 is placed inside the limiting groove 5. The connecting static pressure pile 8 is rotated to limit the entire connecting static pressure pile 8 inside the static pressure pile body 1, ensuring that the top of the static pressure pile body 1 and the bottom of the connecting static pressure pile 8 are concentric when the static pressure pile body 1 and the connecting static pressure pile 8 are connected, and ensuring that the entire static pressure pile is in a vertical state.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
