Description

Technical Field

[0001] The utility model relates to the technical field of tunnel boring equipment, in particular to a pea gravel tank bottom supporting structure for a small-diameter tunnel boring machine. Background Art

[0002] In tunnel construction, the excavation diameter of the tunnel boring machine cutter head is usually about 300mm larger than the outer diameter of the segment. After the segment is assembled, it is necessary to blow pea gravel into the construction gap between the segment and the excavated tunnel, and then backfill and grouting are performed to ensure the stability of the assembled segment.

[0003] When blowing and filling pea gravel, it is necessary to transport the pea gravel from the outside to the blowing and filling location. In the prior art, pea gravel is mostly transported in pea gravel tanks, which are then transported into the tunnel by flatbed trucks, and finally the pea gravel tanks are transferred to the pea gravel tank support structure of the tunnel boring machine trolley, and the pea gravel blowing and filling operation can be carried out. When transferring the pea gravel tank, a crane is mostly used for hoisting. This method has no problem for large-diameter tunnel boring machines, but for small-diameter tunnel boring machines (less than 6 meters in diameter), due to the limited internal space, it is often impossible to arrange a crane without changing the volume of the pea gravel tank. However, due to the problems of laying rails and parking accuracy of the tunnel boring machine, it is difficult to align the support track of the bean gravel tank on the flatbed car with the support structure of the bean gravel tank on the tunnel boring machine trolley, and it is easy to be misaligned in the front and back, up and down, left and right directions. During construction, it takes a lot of time to carry out the alignment operation. In some cases, the alignment cannot be achieved, resulting in the inability to translate the bean gravel tank horizontally. The only way to meet the demand for lifting and moving the tank is to reduce the volume of the bean gravel tank, which will greatly reduce the transportation efficiency of the bean gravel and ultimately affect the efficiency of tunnel construction.
