[0003] However, in the existing technology, in order to prevent the silt soil from causing damage to the surrounding roads and building piles due to the soil squeezing effect, the piles may even tilt to one side after being squeezed, thus affecting the verticality of the building. Therefore, it is necessary to divert the flow direction of the silt soil before it is squeezed onto the piles, so as to reduce the squeezing force direction of the piles caused by the silt flow.
[0004] Therefore, we need an anti-squeezing structure for pipe pile construction in muddy soil, which can solve the existing problem of reducing the squeezing force on the pile body in the muddy soil, and can also realize the diversion of the flow direction of the silt that squeezes the pile body.

[0009] Preferably, the number of the diverter baffles is two, and the two diverter baffles are symmetrically arranged along the center point of the fixing rod.
[0010] Preferably, the limiting grooves are arranged in a "concave" shape, the number of the limiting grooves is six, and two limiting grooves are arranged in a circular array along the center point of the pipe pile column body.
[0011] Preferably, the water-permeable holes are arranged in a "diamond" shape, and there are several water-permeable holes, and the several water-permeable holes are evenly distributed on the surface of the blocking plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: by fixing the end of the fixing rod to the surface of the installation sleeve, and then fixing the end of the support frame to the inner surface of the diversion baffle, when the base is fixed in the silt soil layer, the pipe pile column body will be erected in the silt soil. Due to the geological height, the silt will flow and impact the surface of the pipe pile column body, causing it to tilt.

Due to the geological height, the silt will flow and impact the surface of the pile column body 2, causing it to tilt. Through the fixing action of the support frame 6 and the fixing rod 7, one end of the diverter baffle 5 is directed toward the silt impacting the surface of the pile column body 2. Therefore, the diverter baffle 5 blocks and diverts the silt impacting the surface of the pile column body 2, thereby preventing it from being squeezed onto the surface of the pile column body 2 and causing it to tilt. In addition, the number of installation sleeves 3 on the surface of the pile column body 2 can be adjusted according to the depth of the silt.
[0022] Embodiment 2
[0023] Refer to the attached Figures 1 to 5 On the basis of the first embodiment, in order to block the stones in the sludge, the inner surface of the diversion baffle 5 is fixedly connected to the end of the blocking plate 8, and the surface of the blocking plate 8 is provided with a water-permeable hole 10;
[0024] By fixing the inner surface of the diverter baffle 5 to the end of the blocking plate 8, and then arranging the water-permeable holes 10 on the surface of the blocking plate 8, when the silt is about to impact the surface of the pipe pile column body 2 and is blocked and diverted by the diverter baffle 5, the stones in the silt are blocked by the blocking plate 8, and at the same time, the water-permeable holes 10 on the surface of the blocking plate 8 can realize the flow of water in the silt, which can protect the pipe pile column body 2.
[0025] Embodiment 3
[0026] Refer to the attached Figures 1 to 5 On the basis of the second embodiment, in order to realize that the installation sleeve 3 can be stably installed on the surface of the pipe pile column body 2, a limiting groove 4 is provided on the surface of the pipe pile column body 2, and the surface of the limiting groove 4 is against the end of the fixing bolt 9, and the surface of the fixing bolt 9 is threadedly connected to the surface of the threaded hole 11, and the threaded hole 11 is provided on the surface of the installation sleeve 3;
[0027] By threading the surface of the fixing bolt 9 to the surface of the threaded hole 11, the end of the fixing bolt 9 is pressed against the surface of the limiting groove 4, and the knob fixing bolt 9 is turned so that the installation sleeve 3 can be firmly installed on the surface of the pile column body 2 to prevent the diverter baffle 5 from driving the installation sleeve 3 to rotate on its surface when the silt squeezes the pile column body 2, thereby limiting the direction of the diverter baffle 5, and adjusting the position of the installation sleeve 3 on the surface of the pile column body 2 according to the depth of the silt. At the same time, the installation sleeve 3 can be rotated and adjusted on its surface according to the direction in which the silt flows and impacts the pile column body 2. Therefore, the end of the diverter baffle 5 on the surface of the installation sleeve 3 can be firmly directed toward the silt flowing surface.
[0028] In actual use, the end of the fixing rod 7 is fixedly connected to the surface of the installation sleeve 3, and then the end of the support frame 6 is fixedly connected to the inner surface of the diverter baffle 5. When the base 1 is fixed in the silt soil layer, the pile column body 2 will be erected in the silt soil. Due to the geological height, the silt will flow and impact the surface of the pile column body 2, causing it to tilt. Under the fixing action of the support frame 6 and the fixing rod 7, one end of the diverter baffle 5 is directed toward the silt direction that impacts the surface of the pile column body 2. Therefore, the diverter baffle 5 blocks and diverts the silt that impacts the surface of the pile column body 2, thereby preventing it from being squeezed onto the surface of the pile column body 2 and causing it to tilt. The number of installation sleeves 3 on the surface of the pile column body 2 can be adjusted according to the depth of the silt. The inner surface of the diverter baffle 5 is fixedly connected to the end of the blocking plate 8, and then a water permeable hole 10 is set on the surface of the blocking plate 8. When the silt is about to impact the pile column body 2 When the surface of the pipe pile column is blocked by the diversion baffle 5, the stones in the silt are blocked by the blocking plate 8. At the same time, the water-permeable holes 10 on the surface of the blocking plate 8 can realize the circulation of water in the silt. It is necessary to protect the pipe pile column body 2. By threading the surface of the fixing bolt 9 to the surface of the threaded hole 11, the end of the fixing bolt 9 is pressed against the surface of the limiting groove 4. When the knob fixes the bolt 9, the installation sleeve 3 can be firmly installed on the surface of the pipe pile column body 2 to prevent the diversion baffle 5 from driving the installation sleeve 3 to rotate on its surface when the silt squeezes the pipe pile column body 2, which plays a limiting role in the direction of the diversion baffle 5, and can adjust the position of the installation sleeve 3 on the surface of the pipe pile column body 2 according to the depth of the silt. At the same time, the installation sleeve 3 can be rotated and adjusted on its surface according to the direction in which the silt flows and impacts the pipe pile column body 2. Therefore, the end of the diversion baffle 5 with a stable surface of the installation sleeve 3 can face the silt flowing surface.
