Description

[Technical Field]

[0001] The present invention relates to the technical field of ground pile structures for installing soundproof panels, and in particular to spiral ground pile structures for soundproof walls. [Background technology]

[0002] Acoustic panels are noise barriers that are specially designed to stand between a noise source and a sound receiving point. Typically designed for a specific sound source and a specific location (or area) to be protected, acoustic panels are primarily used for sound insulation and noise reduction on roads, highways, overpasses, and other noise sources.

[0003] The ground pile structures commonly used for conventional soundproof panels include ground piles that combine precast concrete and steel connection structures, and ground piles that combine anchor rods and steel connection structures.Of these, precast concrete ground piles have a long construction period and are expensive, so anchor rod ground piles are preferentially selected when the soil quality of the ground is suitable.

[0004] However, conventional anchor rod ground piles have anchor rods that are almost bare and are inserted directly into the ground soil using a pile driver during construction. This means that the interface between the anchor rod and the ground soil is small, and the pull-out strength and overturning strength are weak. In particular, when subjected to strong winds, earthquakes, or vehicle vibration loads, the foundation is prone to tilting and displacement, which reduces the overall structural stability of the sound barrier and makes it impossible to meet the safety requirement of long-term function.

[0005] To solve the above problems, a spiral ground pile structure for soundproof walls is desired. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of this invention is to provide a spiral ground pile structure for soundproof walls, which solves the problem mentioned in the background art above: in conventional anchor rod-type ground piles, the anchor rods are mostly bare rods, and are inserted directly into the ground soil using a pile driver. However, because the interface between the bare rods and the ground soil is small, the pull-out strength and overturning strength are weak, which reduces the stability of the ground pile structure. [Means for solving the problem]

[0007] To achieve the above object, the present invention provides the following technical solution: a spiral ground pile structure for a soundproof wall, comprising a plurality of anchor rods distributed sequentially from left to right, support columns fixedly connected to the tops of the anchor rods by bolts, two locking grooves symmetrically opened on the left and right sides of the support columns, two fixing assemblies symmetrically connected to the support columns, a soundproof panel fixedly fastened by the fixing assemblies between two adjacent locking grooves of any two adjacent support columns, a spiral blade fixedly fitted on the outer circumferential surface of the lower half of the anchor rods, and a ground gripping assembly connected to the upper half of the anchor rods; The ground gripping assembly increases the interface area between the anchor rod and the ground soil.

[0008] Preferably, the width of the spiral blade is equal to or greater than the radius of the anchor rod. The advantages of this arrangement are as follows: after being inserted into the ground soil, the spiral blade can significantly increase the contact area between the anchor rod and the ground soil, and further improve the pull-out strength and overturning strength of the anchor rod, thereby effectively improving the stability and reliability of the ground pile structure.

[0009] Preferably, the earth gripping assembly includes a pushing mechanism and a guide mechanism connected to the outer periphery of the upper half of the anchor rod, and a plurality of sets of earth gripping teeth such as elastic metal plates are connected to the guide mechanism at equal angles to form a ring, and the pushing mechanism pushes the plurality of sets of earth gripping teeth through the guide mechanism to insert them into the ground soil. The advantage of this installation is that by inserting the plurality of sets of earth gripping teeth into the ground soil, the contact area between the anchor rod and the ground soil can be further increased together with the spiral blade, greatly improving the stability and reliability of the ground pile structure.

[0010] Preferably, the number of the earth gripping teeth in each set is at least five, and the length of the earth gripping teeth inserted into the soil is equal to or greater than the width of the spiral blade.

The advantages of installing it in this way are as follows: the pushing mechanism pushes the movable piece to move downward along the first limiting groove, which causes the movable piece to move downward with a set of earth gripping teeth, which are then restricted by the close slopes of the two adjacent baffles, allowing the earth gripping teeth to be inserted into the soil along the direction of the slope, ensuring that the earth gripping teeth can be inserted into the soil smoothly and reliably at an angle, and that the earth gripping teeth can effectively increase the contact area between the anchor rod and the ground soil, thereby improving the pull-out strength and overturning strength of the anchor rod.

Furthermore, by striking the protruding blocks downwards or upwards with a tool such as a hammer, an operator can easily and smoothly insert the earth gripping teeth into or remove them from the soil, which makes the installation and removal of the anchor rod simple and convenient and improves the practicality of the earth pile structure.

[0013] Preferably, the fixing assembly includes a plurality of screws threadedly inserted into the front face of the support column from top to bottom at equal intervals, with the rear ends of the screws penetrating the front face of the support column and inserted into the locking grooves, and with stainless steel fasteners rotatably connected to the rear ends of the screws, which can be pressed by the screws to tightly abut against the front face of the soundproof panel. The advantage of this installation is that by rotating the screws and moving the stainless steel fasteners toward or away from the soundproof panel, the soundproof panel can be easily tightened or loosened together with the locking grooves.

[0021] Specifically, after being inserted into the ground soil, the spiral blade 6 can ensure that the contact area between the anchor rod 1 and the ground soil is significantly increased, thereby improving the pull-out strength and overturning strength of the anchor rod 1, and thereby effectively improving the stability and reliability of the ground pile structure.

[0023] Specifically, by inserting multiple sets of earth gripping teeth 71 into the ground soil, the contact area between the anchor rod 1 and the ground soil can be further increased together with the spiral blade 6, thereby significantly improving the stability and reliability of the ground pile structure.

[0024] Referring to Figures 4, 5 and 7, the number of the soil gripping teeth 71 in each set is at least five, and the length of the soil gripping teeth 71 inserted into the soil is equal to or greater than the width of the spiral blade 6.

[0025] Specifically, the earth gripping teeth 71 inserted into the ground soil ensure that the contact area between the anchor rod 1 and the soil can be significantly increased.

[0027] Specifically, the pushing mechanism 73 pushes the movable piece 722 to move downward along the first limiting groove 721, and the movable piece 722 moves downward along with the set of earth gripping teeth 71, so that the adjacent slopes of the two adjacent baffles 723 restrict the earth gripping teeth 71 to be inserted into the soil along the direction of the slope, ensuring that the earth gripping teeth 71 are inserted into the soil smoothly and reliably at an incline, and that the earth gripping teeth 71 can effectively increase the contact area between the anchor rod 1 and the soil of the ground, thereby improving the pull-out strength and overturning strength of the anchor rod 1.

[0028] 3 and 4, the extrusion mechanism 73 includes a plurality of second limiting grooves 731 that are opened at equal angles to form a ring on the outer circumferential surface of the anchor rod 1.

[0033] Next, the second fixing plate 12 is fixed and connected to the first fixing plate 11 by bolts, thereby completing the fixing and connection of the support column 2 and the anchor rod 1.
