Description
Technical Field
[0001] The present application relates to the technical field of immersed tubes, and more specifically, to a pile-driven immersed tube for building foundation construction. Background Art
[0002] Gravel piles are a type of composite foundation reinforcement pile made of crushed stone or pebbles as the main material. The soil in the river channel is soaked in water for a long time, and has a high porosity, high compressibility, and thixotropy and rheological characteristics. Gravel piles are often used to process the foundation in this soil, and the construction of gravel piles usually adopts the sunken tube method.
[0003] The document with the prior art announcement number CN221193318 provides a pipe-sinking structure for gravel pile construction. The stones pass through the connecting pipe and are finally discharged through the discharge hole on the discharge pipe. The raised part in the discharge pipe facilitates the discharge of the gravel from the discharge hole on the side wall and further falls from the groove on the pile head. The pile tip can impact and squeeze the stones. At the same time, the lower end surface of the pile head presses the gravel. The pipe body repeatedly rises and falls to discharge the stones and then presses them. The number of stones falling can be controlled by sliding the mounting ring. In the utility model, the number of stones falling can be controlled by sliding the mounting ring on the discharge pipe, so that the gravel pile is more uniform. The pile head with a pile tip at the lower end squeezes the stones so that the stones are pressed against the side wall of the pile hole, making the gravel pile tighter and more stable.
[0004] Although this device has many beneficial effects, the following problems still exist: when workers drop gravel, the gravel falls directly from a high altitude to the raised part. The falling speed of the gravel is fast and the impact force is large, which makes it very easy for the raised part to be damaged by the strong impact, shortening the service life of the raised part. In view of this, we propose a pile-driving pipe for building foundation construction. Utility Model Content

[0030] The present application is further described in detail below with reference to the accompanying drawings.
[0031] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a pile-driven immersed pipe for building foundation construction. The pile-driven immersed pipe for building foundation construction comprises: an immersed pipe body 1;
[0032] A through groove 2 is formed on the outer bottom of the immersed tube body 1, a raised portion 4 for guiding materials is fixedly connected to the inner bottom of the immersed tube body 1, a pile head 5 is installed at the bottom of the immersed tube body 1, and a pile tip 6 is installed at the bottom of the pile head 5;
[0033] A feeding mechanism 3 is provided inside the immersed tube body 1 to slow down the falling speed of the crushed stones;
[0034] The unloading mechanism 3 includes a fixed tube 32, which is located on the inner side of the immersed tube body 1. A plurality of first slides 33 are fixedly connected to one side of the inner wall of the fixed tube 32, and a second slide 34 is fixedly connected to the other side of the inner wall of the fixed tube 32, so as to slow down the unloading speed and prevent the gravel from causing greater damage to the raised part 4.
[0035] Reference Figure 1 and Figure 3 The first slide plate 33 and the second slide plate 34 are both inclined, and the first slide plate 33 and the second slide plate 34 are staggered up and down, so that the gravel can slide down.
[0036] Reference Figure 3 and Figure 4The tops of the first slide 33 and the second slide 34 are fixedly connected to a fixing frame 35, and the top of the inner wall of the fixing frame 35 is fixedly connected to a plurality of pads 36 for further slowing down the sliding speed of the gravel, and the pads 36 are made of rubber.
[0037] Reference Figure 1 and Figure 5 The top of the fixed tube 32 is fixedly connected to a mounting ring 31, and the top of the immersed tube body 1 is fixedly connected to a screw 37. The mounting ring 31 is slidably sleeved on the outside of the screw 37, and a nut 38 is threadedly sleeved on the outside of the screw 37, which makes it convenient for the staff to fix the fixed tube 32 and the mounting ring 31, and convenient for the staff to remove the fixed tube 32 from the inside of the immersed tube body 1.
[0038] Reference Figure 1 and Figure 5 The inner size of the mounting ring 31 is larger than the maximum inner size of the immersed tube body 1 , thereby preventing the mounting ring 31 from entering the inner side of the immersed tube body 1 , so that the mounting ring 31 can be placed on the top of the immersed tube body 1 .
[0039] Reference Figure 1 、 Figure 2 and Figure 6 , a mounting box 7 is fixedly connected to one side of the immersed tube body 1, and a slot is opened at the bottom of the mounting box 7. A screw rod 9 is rotatably connected in the slot through a sealed bearing. A motor 8 is installed on the top of the inner wall of the mounting box 7. The motor 8 is connected to an external controller and a power supply. It is a prior art and will not be described in detail here. The bottom end of the output shaft of the motor 8 is fixedly connected to the top of the screw rod 9. A retaining ring 10 is provided on the outer thread of the screw rod 9. Guide bars 11 are fixedly connected to both sides of the immersed tube body 1. Guide grooves for slidingly cooperating with the guide bars 11 are opened on both sides of the inner wall of the retaining ring 10, and the guide bars 11 are located in the guide grooves. When the motor 8 is started, it can drive the screw rod 9 to rotate. The rotation of the screw rod 9 can make the retaining ring 10 move up and down along the direction of the guide bar 11, thereby controlling the retaining ring 10 to block the through groove 2, which is convenient for adjusting the size of the through groove 2, controlling the number of stones falling, and making the gravel pile more uniform.
[0040] Reference Figure 1 and Figure 2 The opening on one side of the installation box 7 is connected to a cover plate by a threaded rod, which is convenient for sealing the opening on one side of the installation box 7 to prevent soil from entering the inside of the installation box 7.
[0041] The implementation principle of a pile-driving pipe for building foundation construction in the embodiment of the present application is as follows: when the staff needs to put in gravel, the fixing tube 32 can be placed on the inner side of the immersed pipe body 1, and the mounting ring 31 can be sleeved on the outer side of the screw 37, and then the nut 38 can be screwed on the outer side of the screw 37 so that the bottom of the nut 38 abuts against the top of the mounting ring 31, thereby fixing the mounting ring 31. At this time, when the gravel is put in, the gravel slides down through the first slide 33, and during the sliding process, the gravel pushes the pad 36 to bend, so that the gravel slides down to the second slide 34 again. After the gravel passes through multiple first slides 33, second slides 34 and pads 36 in sequence, the gravel falls on the raised portion 4 and finally slides out through the through groove 2 along the raised portion 4, thereby preventing the gravel from falling directly from a higher place and hitting the raised portion 4 directly.
[0042] The embodiment of the present application provides a pile-driving pipe for building foundation construction. By setting a feeding mechanism 3, when the staff throws gravel, the gravel can gradually slide along the first slide plate 33 and the second slide plate 34 to the raised portion 4, thereby preventing the gravel from falling directly from a high altitude and hitting the raised portion 4, thereby extending the service life of the raised portion 4.
