Description

Technical Field

[0001] The utility model belongs to the technical field of anchor rods, and more specifically relates to a vibration dewatering anchor rod device. Background Art

[0002] As the scale and depth of foundation pit projects increase, construction difficulties and engineering accidents are gradually increasing. Especially for areas with mainly sandy soil, the physical and mechanical properties of the soil layer are extremely poor, and the strength and stability of the soil layer are easily affected by the water content, making the safety and quality issues of deep foundation pit construction become very urgent and prominent.

[0003] Slope and deep foundation pit excavation support projects have always received great attention. Traditional support structures cannot meet the safety level requirements of deep foundation pit support. In recent years, anchor support structures such as grouting anchors, self-drilling anchors, high-pressure jet expansion anchors, and bladder expansion anchors have been developed. Although the above-mentioned anchor support structures have achieved certain results in construction technology and support effects, many problems will arise in actual applications. The grouting body of the grouting anchor is insufficient in compressive strength and cannot be recycled. The self-drilling anchor has insufficient anchoring force. The high-pressure jet expansion anchor is difficult to drill a hole. The bladder expansion anchor has poor construction controllability and the airbag is easily damaged.

[0004] At present, deep foundation pit drainage is one of the most effective measures to improve soil strength and slope stability in the treatment of weak slopes. Pipe wells are usually used for foundation pit dewatering, but when pumping water from sandy soil layers, a large amount of sand is lost, resulting in weak zones around the pipe wells, which poses a huge safety hazard to the foundation. In recent years, technicians have begun to study the combination of anchoring technology and foundation pit drainage to achieve dual treatment of weak slopes. A drainage composite self-drilling tire string anchor support structure is disclosed in the patent application number 201420805558.2. The structure can effectively provide anchoring force, but the soil layer is easily disturbed during the construction of the drainage board, and the structure of the self-drilling tire string anchor is complex, and the manufacturing process and cost are high. The drainage measures and the support structure in the support structure are independent of each other, which not only affects the construction progress, but also increases the difficulty of construction. A vibration drainage anchor support structure for sandy soil layers, with a publication number of CN212104106U in China, comprises a vibration drainage anchor, a siphon drainage device and a variable frequency vibration device; the vibration drainage anchor comprises a spiral drill tip, a water filter pipe, a hollow steel pipe, a tail steel pipe, a vibration head and a conductor, the spiral drill tip, the water filter pipe, the hollow steel pipe and the tail steel pipe are connected in sequence by threads, a plurality of water filter holes are arranged on the water filter pipe, and a one-way permeable geotextile is tied on the surface of the water filter holes; the vibration drainage anchor is drilled into the slope surface according to the drilling angle, a lattice frame and a retaining plate are arranged on the slope surface of the foundation pit with the anchor as the axis, and the tail end of the tail steel pipe of the vibration drainage anchor is fixed on the lattice frame.

[0005] This technical solution utilizes the characteristic that sandy soil is easily liquefied by vibration. A vibrating head is inserted into the anchor rod body to drive the anchor rod to resonate, thereby achieving liquefaction of the sandy soil layer within a certain radial range of the anchor rod to produce free water, and the free water flows to the anchor rod and is discharged, thereby achieving the purpose of reinforcing the sand layer. However, in actual use, after the device vibrates and destroys the sand layer, it is necessary to pull the vibrating head out of the anchor rod, insert a siphon tube and start the water pump. Due to the step of pulling out the vibrating head, the device is more troublesome in actual use and is not conducive to large-scale use. Utility Model Content
