Description
Technical Field
[0001] The utility model relates to the technical field of cement-stabilized crushed stone base grouting equipment, and more specifically to an edge grouting device for cement-stabilized crushed stone base road construction. Background Art
[0002] During the road construction process, the road surface must be paved after the roadbed is completed. However, since the roadbed is easily softened and deformed by water and is prone to dust, a roadbed stabilization layer must be laid on the roadbed to stabilize the roadbed and protect it from water erosion. Generally, high-grade pavements basically use cement-stabilized graded crushed gravel as the stabilization layer.
[0003] In the actual construction process, in order to facilitate the effective control of the road width to save the loss of raw materials, and provide a certain lateral pressure to facilitate the compaction and forming of the edge of the road surface, a lateral formwork construction process is generally adopted, and it is usually rolled by a large-tonnage roller after being paved by a paver. Since the base layer is squeezed and extended to the edge during the rolling process of the roller, the paver often lacks fillers at the edge position near the formwork. In order to improve the forming effect of the edge position of the road surface, the prior art generally adopts manual or mechanical methods to fill and grout the edge of the base layer. The above-mentioned manual or mechanical methods have the following problems: first, the existing grouting equipment is directly placed on the edge of the paver. During use, it is necessary to adjust the lateral distance of the grouting slot according to the grouting position. When the distance is small, the grouting hose is easily dragged onto the road surface, which has the risk of damage and affects the grouting flow rate. The stability is not good enough; second, after the slurry in the grouting equipment is used up, it is still necessary to manually add materials, which increases the construction time and is not convenient enough. Utility Model Content
[0004] The purpose of the utility model is to provide an edge grouting device for road construction with a cement-stabilized crushed stone base. On the one hand, the device can tighten the grouting hose to prevent the grouting hose from being dragged onto the road surface and ensure the grouting flow rate. On the other hand, the slurry barrel can be automatically detected and fed to ensure the continuous working time of the edge grouting device and save work time.

[0007] As a further optimization of the present solution, the front end surfaces on both sides of the ironing plate are provided with clamps, a rotating shaft is installed between the clamps, a telescopic tensioning rod is provided outwardly on the shaft body of the rotating shaft, a non-telescopic section of the telescopic tensioning rod is fixed to the shaft body of the rotating shaft and a ring is connected to the telescopic section, a hose passes through the inside of the ring and lifts the hose upward for tensioning, and the rotating shaft and the telescopic tensioning rod are both limited by side locking nuts.
[0008] As a further optimization of this solution, the liquid level sensor does not contact the stirring rod of the stirring assembly.
[0009] As a further optimization of this solution, an electric-controlled valve is also provided at the front outlet end of the grouting barrel, and the stirring assembly, the electric-controlled valve and the liquid level sensor are all connected to the control panel through lines.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] The utility model can detect the remaining amount of slurry in the grouting bucket by setting a grouting pipeline structure and combining it with a liquid level sensor. When the amount is lower than the threshold, the electric control valve on the grouting pipeline can be opened to automatically inject new slurry into the grouting bucket, replacing the traditional frequent manual feeding, ensuring the continuous working time of the edge grouting device and saving working hours.
[0012] The utility model provides a rotating shaft and a telescopic tensioning rod structure, which facilitates the adjustment of the support angle and the support length of the telescopic tensioning rod, provides tension support for the hose throughout the entire process, and caters to the grouting slot position adjusted by the lateral adjustment rod and the longitudinal adjustment rod, thereby preventing the grouting hose from being dragged onto the road surface and causing damage, and ensuring the grouting flow rate.
