Description

Technical Field

[0001] The utility model relates to the technical field of soft soil processing devices for roadbeds in highway engineering, in particular to a soft soil processing device for roadbeds of highways. Background Art

[0002] Highway industry specifications define soft soil foundation as a weak soil layer with low strength and high compression, most of which contain a certain amount of organic matter. The properties of soft soil are closely related to the layered structure, sedimentary age, and genetic type of the foundation soil. Due to its engineering properties such as high water content, high compressibility, poor permeability, and strong rheology, soft soil generally cannot be used directly as a natural foundation. It needs to be reinforced to reduce the settlement or uneven settlement caused by the highway subgrade under load.

[0003] At present, the treatment method for soft soil roadbed is generally the solidification method, which uses solidifying materials to be poured into the geotechnical engineering foundation to fully integrate the foundation to achieve the reinforcement of the soft soil foundation. In actual operation, it is generally necessary to first groove the roadbed, and then pour the solidifying material into the groove to integrate with the soft soil. This method has the problems of complex construction process and low solidification efficiency. Therefore, a soft soil treatment device for highway roadbed is needed. Utility Model Content

[0004] The utility model aims to provide a soft soil processing device for a highway roadbed to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soft soil processing device for a highway roadbed, comprising a processing device body, a filling barrel, a feed port and a frame, wherein universal wheels are arranged at the four corners of the bottom of the processing device body, and a frame is fixed to one end of the top of the processing device body, a screw rod is arranged inside the frame, and a driving block is sleeved on the screw rod, a movable plate is arranged on one side of the driving block, a first rotating drive mechanism is fixed at the central position of one side of the movable plate through a fixing piece, and the output end of the first rotating drive mechanism is connected to the filling barrel, a feed port is arranged at the top end of one side of the filling barrel, and a pile driving head is arranged at the bottom end of the filling barrel, and discharge holes are evenly opened on the outside of the filling barrel.

[0006] Preferably, fixed blocks are fixed on both sides of the processing device body, and brackets are provided below the fixed blocks, and supporting feet are provided at both ends of the bottom of the bracket.

[0007] Preferably, spiral elements are evenly distributed on the outside of the filling cylinder, and blades are evenly arranged on the outside of the bottom of the filling cylinder.

[0008] Preferably, a second rotation drive mechanism is fixed to the top of the frame, and an output end of the second rotation drive mechanism is connected to the screw rod.

[0009] Preferably, guide rods are provided on both sides of the frame, and the side of the movable plate close to the guide rods is slidably connected to the guide rods through a guide sleeve.

[0010] Preferably, a screw rod vertically passes through the top of each of the fixing blocks, and the bottom end of each of the screw rods is connected to the bracket via a rotating sleeve.

[0011] Preferably, the number of the blades is 4 groups, and the blades are all arc-shaped structures, and alloy cutter heads are welded on the outer sides of the blades.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The soft soil treatment device for the highway roadbed is equipped with a treatment device body, a filling cylinder, a feed port, a frame, a screw, a driving block, a movable plate, a first rotating driving mechanism, a pile driving head and a discharge hole. The treatment device body is moved to the soft soil roadbed that needs to be treated, and the filling cylinder is driven to rotate by the first rotating driving mechanism. At the same time, the second rotating driving mechanism drives the screw to rotate, so that the driving block moves downward along the screw, and drives the pile driving head to drill downward to groove the soft soil roadbed. At the same time, a solidifying material conveying pipeline is connected through the feed port, and the solidifying material is conveyed into the filling cylinder. In the process of the filling cylinder rotating and drilling, the solidifying material flows out evenly through the discharge hole on the surface of the filling cylinder and merges with the soft soil in the roadbed, so that the bonding force between the soft soil particles is greatly enhanced. The solidifying material is introduced in the process of drilling and grooving, thereby improving the treatment efficiency of the highway soft soil roadbed.

[0014] (2) The soft soil treatment device for the highway roadbed is equipped with a spiral component, a blade and an alloy cutter head. When the filling cylinder rotates, the outer arc surface of the blade first contacts the soft soil, and a force is generated between some obstacles in the soft soil and the outer arc surface. The arc surface effect generates a horizontal thrust on the obstacle. At the same time, the alloy cutter head on the blade helps to improve the structural strength of the blade, and it is not easy to break or damage when encountering an obstacle. The spiral components are evenly distributed on the outside of the filling cylinder, so that the soft soil is stirred when the filling cylinder rotates, thereby improving the fusion effect with the solidifying material.

[0015] (3) The soft soil treatment device for the highway roadbed is equipped with universal wheels, fixed blocks, screws, brackets and legs. The universal wheels can be used to conveniently move and transport the main body of the treatment device. When it is moved to the construction site, the screw can be driven to rotate by a tool, so that the bracket moves down and the legs come into contact with the roadbed surface, thereby improving the support for the main body of the treatment device and making it more stable during operation.
