Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, specifically to a building concrete pipe pile. Background Technology

[0002] In engineering applications, precast concrete pipe piles require one to three concrete pipe pile segments. During construction, the first concrete pipe pile segment is first pressed into the soil, then the second concrete pipe pile segment is connected to the first concrete pipe pile segment, and then the third concrete pipe pile segment is connected to the second concrete pipe pile segment. The splicing method generally involves fixing the end steel plates set on each concrete pipe pile segment by electric welding to complete the assembly of each concrete pipe pile segment.

[0003] According to Chinese Patent Application No. CN201721707241.5, a precast concrete pipe pile includes a pipe pile body. One end of the pipe pile body is provided with an insertion part, and the other end of the pipe pile body is provided with a socket part that can cooperate with the insertion part. The socket part is provided with a plurality of connecting holes, and the insertion part is provided with connectors that respectively cooperate with the connecting holes. The socket part is also provided with a grouting cavity communicating with the connecting holes. The connectors pass through the connecting holes and are disposed in the grouting cavity. Grouting holes are reserved on the side wall of the socket part. This utility model has a simple structure, is easy to install, and has a good connection effect.

[0004] However, the aforementioned device still has some shortcomings in use. For example, after connecting two pipe piles, there are protruding connecting parts on the outside, which not only increases the unevenness of the pile surface but may also cause increased resistance, difficulty in pile driving, or deviation when driven into the soil, thereby affecting construction efficiency and the bearing capacity of the pile foundation. To solve the above problems, we propose a building concrete pipe pile. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete pipe pile for building construction, solving the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A type of concrete pipe pile includes: two pipe pile bodies, the outer walls of which have two upper mounting grooves and two lower mounting grooves, the top surface of which has an upper hole; and an installation assembly disposed on the bottom surface of the lower mounting grooves for connecting the two pipe pile bodies.

[0008] By adopting the above technical solution and setting up installation components to connect the two pipe pile bodies, the existing technology avoids the problem of protruding connectors on the outer wall of the pipe pile body after connection, which would affect subsequent installation.

[0009] Preferably, the mounting assembly includes: a lower hole, the lower hole being formed on the bottom surface of the lower mounting groove, a first bolt being sleeved inside the lower hole, the first bolt being sleeved together with the adjacent upper hole, and a nut being provided inside the upper hole, the nut being threadedly connected to the first bolt.

[0010] By adopting the above technical solution and setting a nut, the two pipe pile bodies can be connected together during use to align the lower and upper holes. At this time, the first bolt can be passed through the upper hole and connected by the nut, thus achieving the initial connection and installation of the two pipe pile bodies.

[0011] Preferably, the mounting assembly further includes: a limiting block, the limiting block being disposed inside the lower mounting groove, the top surface of the limiting block having two first inner grooves, the top surface of the lower mounting groove having two second inner grooves, and a spring being fixedly installed between the first inner grooves and the adjacent second inner grooves.

[0012] By adopting the above technical solution and setting the first inner groove, the limiting block can be pressed down by the spring during use, so that it sticks to and squeezes the first bolt, thereby avoiding the vibration caused by driving the pipe pile body into the soil and causing the first bolt to loosen.

[0013] Preferably, the mounting assembly further includes: a bottom hole, the bottom hole being formed on the bottom surface of the upper mounting groove, the bottom hole communicating with the adjacent lower mounting groove, a second bolt being provided inside the bottom hole, and a threaded groove being formed on the top surface of the limiting block, the threaded groove being threadedly connected to the second bolt.

[0014] By adopting the above technical solution and setting the threaded groove, when the limiting block is attached to and squeezes the first bolt during use, the second bolt can be rotated to connect with the threaded groove, thereby further restricting the first bolt and preventing it from loosening.

[0015] Preferably, the outer walls of the first bolt and the second bolt are provided with a plurality of locking holes.

[0016] By adopting the above technical solution and setting a locking hole, users can easily rotate the first and second bolts with tools, which facilitates the installation operation.

[0017] Preferably, two pile tips are fixedly installed on the bottom surface of the pipe pile body.

[0018] By adopting the above technical solution and setting a pile tip, the pipe pile body can be driven into the soil smoothly, reducing resistance.

[0019] Preferably, two positioning grooves are formed on the top surface of the pipe pile body.

[0020] By adopting the above technical solution and setting a positioning groove for connecting the pile tip of the pipe pile body, not only can the strength after connection be increased, but the two pipe pile bodies can also be limited to align and assist in installation.

[0021] In summary, the present invention has the following main advantages:

[0022] By setting up an installation component to connect two pipe pile bodies, and avoiding the problem of protruding connectors on the outer wall of the pipe pile body after connection in the existing technology, which would affect subsequent installation, the two pipe pile bodies can be connected by mating them together during use, so that the lower hole and the upper hole are aligned. At this time, the first bolt can be passed through the upper hole and connected by the nut, thus realizing the initial connection and installation of the two pipe pile bodies.

[0023] By setting the first inner groove, the limiting block can be pressed down by the spring during use, so that it sticks to and squeezes the first bolt, thereby preventing the first bolt from loosening due to the vibration generated when the pipe pile body is driven into the soil. By setting the threaded groove, after the limiting block sticks to and squeezes the first bolt during use, the second bolt can be rotated to connect with the threaded groove, thereby further restricting the first bolt and preventing it from loosening.

[0024] By setting a locking hole, users can easily rotate the first and second bolts with tools, which facilitates the installation operation. By setting a pile tip, the pipe pile body can be smoothly driven into the soil, reducing resistance. By setting a positioning groove, the pile tip used to connect the pipe pile body can not only increase the strength after connection, but also limit the two pipe pile bodies to align them and assist in installation.

[0030] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0031] refer to Figures 1-3 A type of concrete pipe pile includes: two pipe pile bodies 100, each with two upper mounting grooves 200 and two lower mounting grooves 300 on its outer wall. The top surface of each upper mounting groove 200 has an upper hole 400, and the bottom surface of each lower mounting groove 300 has an mounting assembly 500 for connecting the two pipe pile bodies 100. By using the mounting assembly 500, the two pipe pile bodies 100 can be connected, while avoiding the protruding connectors on the outer wall of the pipe pile bodies 100 after connection, which would affect subsequent installation. The mounting assembly 500 includes: a lower hole 501... The lower hole 501 is opened on the bottom surface of the lower mounting groove 300. The first bolt 502 is sleeved inside the lower hole 501. The first bolt 502 is sleeved together with the adjacent upper hole 400. The upper hole 400 is provided with a nut 503. The nut 503 is threadedly connected to the first bolt 502. By setting the nut 503, the two pipe pile bodies 100 can be connected together during use to align the lower hole 501 and the upper hole 400. At this time, the first bolt 502 can be passed through the upper hole 400 and connected by the nut 503. At this time, the initial connection and installation of the two pipe pile bodies 100 can be achieved.

[0032] refer to Figures 1-3The installation assembly 500 further includes a limiting block 504, which is disposed inside the lower installation groove 300. The top surface of the limiting block 504 has two first inner grooves 505, and the top surface of the lower installation groove 300 has two second inner grooves 506. A spring 507 is fixedly installed between the first inner groove 505 and the adjacent second inner groove 506. By setting the first inner grooves 505, the limiting block 504 can be pressed down by the spring 507 during use, causing it to adhere to and compress the first bolt 502, thereby preventing the first bolt 502 from loosening due to vibration generated when the pipe pile body 100 is subsequently driven into the soil. The mounting assembly 500 also includes a bottom hole 508, which is formed on the bottom surface of the upper mounting groove 200 and is connected to the adjacent lower mounting groove 300. A second bolt 509 is provided inside the bottom hole 508. A threaded groove 510 is provided on the top surface of the limiting block 504. The threaded groove 510 is threadedly connected to the second bolt 509. By providing the threaded groove 510, when the limiting block 504 is attached to and squeezes the first bolt 502 during use, the second bolt 509 can be rotated to connect with the threaded groove 510, thereby further restricting the first bolt 502 and preventing it from loosening.

[0033] refer to Figures 1-3 The outer walls of the first bolt 502 and the second bolt 509 are respectively provided with a number of locking holes 600. By setting the locking holes 600, it is convenient for the user to rotate the first bolt 502 and the second bolt 509 with tools, which facilitates the installation operation. Two pile tips 700 are fixedly installed on the bottom surface of the pipe pile body 100. By setting the pile tips 700, it is convenient for the pipe pile body 100 to be driven into the soil smoothly and reduce resistance. Two positioning grooves 800 are opened on the top surface of the pipe pile body 100. By setting the positioning grooves 800, the pile tips 700 of the pipe pile body 100 are connected. This not only increases the strength after connection, but also limits the two pipe pile bodies 100 to align them and assist in installation.

[0034] Working principle: Please refer to Figures 1-3 As shown, during use, two pipe pile bodies 100 can be joined together, and the positioning groove 800 can be connected to the pile tip 700. This not only increases the strength of the connection, but also aligns the lower hole 501 and the upper hole 400. At this time, the first bolt 502 is passed through the upper hole 400 and connected to the first bolt 502 by the nut 503 for initial connection and installation. At this time, the limiting block 504 is pressed down by the spring 507, so that it sticks to and squeezes the first bolt 502. At this time, the second bolt 509 can be rotated to connect with the threaded groove 510, which can further restrict the first bolt 502, thereby preventing the vibration generated when the pipe pile body 100 is driven into the soil from causing the first bolt 502 to loosen. At the same time, it keeps the outer wall of the pipe pile body 100 without any protruding connection, which facilitates the smooth driving of the pipe pile body 100 into the soil and reduces resistance.
