Description

Technical Field

[0001] The utility model relates to the technical field of plank road supporting structures, in particular to an environmentally friendly and stable ground screw pile structure for plank roads. Background Art

[0002] With the development of urban parks and the times, the form of garden roads has also changed with the update of technology. In particular, in order to protect the ecology, protect greening, and increase the greening coverage rate, the traditional garden road form can no longer meet the development of ecological and environmental protection construction. Driven by technological advancement and changes in the times, we decided to use an overhead form to protect the green area and reduce the impact of building garden roads. We improved the ground piles. Because most small ground piles have smooth surfaces and weak grip when struck into the ground; therefore, we added a spiral structure to the small ground piles, which rotated into the ground to increase the grip. Moreover, the length of the spiral structure and the spiral spacing can be adjusted according to demand without changing the length. We call this improved small ground pile - ground screw.

[0003] Usually, when the ground screw is used, the spiral structure on the outside of the ground screw is used to drill into the inside of the foundation to improve the stability of the ground screw when supporting, and at the same time control the soil to fit closely to the outside of the screw. However, when the ground screw is spirally installed inside the foundation, the ground screw interferes with the foundation soil structure, causing the soil in contact with the ground screw to loosen. In addition, a plank road is installed on the upper part of the ground screw. When people walk on the plank road, the ground screw will vibrate, further causing the soil to loosen. When the soil continues to loosen, the ground screw will tilt, and the tilt will affect the stability of the plank road. For this reason, we have proposed an environmentally friendly and stable ground screw pile structure for plank roads. Utility Model Content

[0004] In view of the shortcomings of the existing environmentally friendly and stable ground screw pile structure for plank roads, the utility model provides an environmentally friendly and stable ground screw pile structure for plank roads, which has the advantage of having a mounting plate installed on the outside of the ground screw. When the ground screw is installed inside the foundation, the mounting plate maintains a close contact state with the foundation, that is, the mounting plate limits the position of the foundation, thereby reducing the loosening of the foundation soil, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: an environmentally friendly and stable ground screw pile structure for plank roads, comprising a ground screw, a threaded groove is provided on the outside of the upper end of the ground screw, a spiral blade is fixedly connected to the outside of the lower end of the ground screw, a screw head is fixedly connected to the upper part of the ground screw, the outer part of the upper end of the ground screw is movably sleeved with a limiting seat, the upper part of the limiting seat is fixedly connected with an extrusion plate, the outer part of the limiting seat is sleeved with a mounting plate, and the upper end of the extrusion plate is sleeved with a threaded sleeve.

[0006] Preferably, the spiral blade is spirally wound around the outside of the ground screw, and the ground screw is spirally installed inside the foundation.

[0007] Preferably, a supporting surface is installed on the top of the screw head, a fastening bolt is fixedly connected to the lower part of the supporting surface, a groove is opened at the top of the screw head, and the fastening bolt is arranged inside the groove.

[0008] Preferably, the outside of the ground screw is sleeved with a base, and the base is pre-buried inside the foundation.

[0009] Preferably, a metal edging strip is fixedly connected to the outside of the support surface, and a protective plate is installed on the outside of the connection between the screw head and the support surface.

[0010] Preferably, the cross section of the limit seat is circular, and the inner side of the mounting plate is fitted to the outer side of the limit seat, and the mounting plate is fitted to the upper end of the foundation.

[0011] Preferably, the inner side of the threaded sleeve is tapered, and the threaded sleeve is sleeved on the outside of the extrusion plate.

[0012] Compared with the existing environmentally friendly and stable plank road ground screw pile structure, the utility model has the following beneficial effects:

[0013] 1. The environmentally friendly and stable ground screw pile structure for plank roads is characterized in that the threaded sleeve is rotated to adjust the position of the threaded sleeve outside the ground screw. At the same time, the ground screw is rotated, and the ground screw is injected into the inside of the foundation. The foundation applies pressure to the mounting plate. According to the different inclination angles of the ground screw, the mounting plate is lifted at the angle outside the limit seat, and the extrusion plate is extruded and installed inside the threaded sleeve, driving the extrusion plate to maintain extrusion limitation with the outside of the ground screw, thereby improving the stability of the mounting plate when positioned outside the ground screw. The mounting plate can adjust the drilling depth of the ground screw, and after the mounting plate is set at the upper end of the foundation, the mounting plate maintains contact with the ground, and the mounting plate protects the foundation to avoid the loss of soil in contact with the ground screw. At the same time, the drilling depth of the ground screw can be adjusted.

[0014] 2. The environmentally friendly and stable ground screw pile structure of the plank road is injected into the interior of the foundation through the ground screw, and the height between the screw head and the foundation is adjusted at the same time, that is, the screw head is suspended at the upper end of the foundation, and a supporting surface is installed on the upper part of the screw head. That is, when the supporting surface is installed, the material for installing the supporting column is reduced, which in turn plays a role in reducing the installation cost and ensuring the stability of the supporting surface during installation.

[0023] See also Figure 1The spiral blade 3 is spirally coiled on the outside of the ground screw 1, and the ground screw 1 is spirally installed inside the foundation. The spiral blade 3 is spirally shaped. When controlling the installation of the ground screw 1, by rotating the ground screw 1, the ground screw 1 can be spirally injected into the inside of the foundation through the spiral blade 3, thereby improving the convenience of maintaining the ground screw 1 when installed inside the foundation. At the same time, after the ground screw 1 is extended inside the foundation, the stability of the ground screw 1 when supporting can be guaranteed.

[0024] See also Figure 2 A support surface 5 is installed on the top of the screw head 4; the support surface 5 can be a plank road or a tree-lined road, etc., and is used in the above-mentioned scenarios.

[0025] The supporting surface 5 is built on the upper part of the screw head 4, and the screw head 4 provides auxiliary support for the position of the supporting surface 5. The lower part of the supporting surface 5 is fixedly connected with a fastening bolt 6. A groove is opened at the top of the screw head 4, and the fastening bolt 6 is arranged inside the groove. The groove is opened at the top of the screw head 4. After the supporting surface 5 is placed on the upper part of the screw head 4, the fastening bolt 6 is installed inside the supporting surface 5, and the fastening bolt 6 passes through the inside of the groove, that is, the fastening bolt 6 can fix the position of the screw head 4, thereby improving the stability of the supporting surface 5 when it is built at the upper end position of the screw head 4.

[0026] See also Figure 2 The outside of the ground screw 1 is sleeved with a base 8, and the base 8 is pre-buried in the foundation. By pre-buried the base 8 in the foundation, when the ground screw 1 is spirally installed in the foundation, the ground screw 1 passes through the base 8, that is, the base 8 limits the position of the ground screw 1, thereby reducing the shaking of the ground screw 1 after being installed in the ground screw 1, which in turn causes the deviation of the spiral conveying position.

[0027] See also Figure 1 The outside of the supporting surface 5 is fixedly connected with a metal edging strip 7, and a protective plate is installed on the outside of the connection between the screw head 4 and the supporting surface 5. The metal edging strip 7 is fixedly connected to the outside of the supporting surface 5, and the metal edging strip 7 protects the outside of the supporting surface 5. At the same time, a protective plate is installed on the outside of the connection between the screw head 4 and the supporting surface 5. The protective plate provides limited protection for the screw head 4 to reduce rainwater from sliding to the outside of the screw head 4, which may cause corrosion damage to the screw head 4.

[0028] See also Figure 5The cross-section of the limit seat 9 is circular, and the inner side of the mounting plate 11 is fitted on the outer side of the limit seat 9. The mounting plate 11 is fitted and installed on the upper end of the foundation. The outer side of the limit seat 9 is circular, and the inner side of the mounting plate 11 is sleeved on the outer side of the limit seat 9. That is, when the installation angle of the ground screw 1 changes, the angle of the extrusion plate 10 outside the limit seat 9 is controlled. That is, when the ground screw 1 needs to be tilted, after adjusting the angle of the mounting plate 11, the mounting plate 11 is controlled to continue to maintain an inclined state with the foundation, and after the mounting plate 11 is covered on the foundation, the position of the mounting plate 11 is avoided from being offset, that is, the stability of the ground screw 1 when the position is limited is ensured, and the problem of soil loss on the upper part of the foundation is avoided.

[0029] See also Figure 5 The inner side of the threaded sleeve 12 is tapered, and the threaded sleeve 12 is sleeved on the outside of the extrusion plate 10. By rotating the threaded sleeve 12, the position of the threaded sleeve 12 outside the ground screw 1 is adjusted. At the same time, the ground screw 1 is rotated, and the ground screw 1 is spirally installed inside the foundation. At the same time, the foundation applies pressure to the mounting plate 11, that is, the mounting plate 11 drives the extrusion plate 10 to move to the inner side of the threaded sleeve 12. After the threaded sleeve 12 applies pressure to the mounting plate 11, the extrusion plate 10 is controlled to be squeezed inward, and the position of the supporting mounting plate 11 outside the ground screw 1 can be limited. At the same time, the position of the mounting plate 11 outside the ground screw 1 is fixed, that is, the depth of the ground screw 1 injected into the foundation can be accurately adjusted.

[0030] Working principle: When in use, a base 8 is installed inside the foundation, and a traction device is used to fix the screw head 4 and control the rotation of the ground screw 1. The ground screw 1 is spirally injected into the foundation through the spiral blade 3, and the threaded sleeve 12 is rotated. The threaded sleeve 12 limits the drilling depth of the ground screw 1. At the same time, the ground screw 1 is injected into the base 8 to ensure the stability of the ground screw 1 when it is positioned inside the foundation. When the ground screw 1 is continuously pushed to be injected into the foundation, the mounting plate 11 remains in contact with the upper part of the foundation. When the equipment is fixed, a supporting surface 5 is installed on the upper part of the screw head 4, and a fastening bolt 6 is installed inside the supporting surface 5. The fastening bolt 6 passes through the groove provided on the outside of the screw head 4 and is spirally installed inside the supporting surface 5, so as to improve the stability of the supporting surface 5 when the upper end position of the screw head 4 is limited. At the same time, a metal edging strip 7 is installed on the outside of the supporting surface 5, that is, the metal edging strip 7 protects the outside of the supporting surface 5.
