Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] Such as figure 1 , figure 2 and image 3 As shown, the rapid compacting reinforcement device of the present invention includes a cylindrical frame 14, and two strip-shaped holes are symmetrically processed on the side wall of the frame 14, and a strip-shaped compacting plate is placed in each strip-shaped hole. 7. The extruded plate 7 and the frame 14 are not connected, and the two ends of the frame 14 are installed with the head 2 and the hydraulic cylinder 13 respectively, and the bolt 1 is installed on the side of the head 2 away from the frame 14; along the extruded plate 7 In the lengthwise direction, three fixing seats 15 are fixedly connected on the inner side wall of the compacted plate 7; along the axial direction of the frame 14, a base 4 and a connecting rod frame 9 are arranged in the frame 14, and the base 4 is connecte...

Provided are quick existing roadbed compaction and reinforcement device and a reinforcement method. The quick existing roadbed compaction and reinforcement device comprises a cylindrical rack providedwith two strip-shaped holes formed in a side wall, wherein compaction plates are arranged in the strip-shaped holes, seal heads and hydraulic cylinders are arranged at two ends of the rack, a base and a connecting rod frame are arranged in the rack, and the compaction plates are connected with a base through first connecting rods. The connecting rod frame is connected with the compaction plates through the connecting rods and is connected with the hydraulic cylinders. The damaged part of an existing roadbed is transversely drilled to form a pre-drilled hole transversely penetrating through the existing roadbed. The reinforcement device is put to the to-be-reinforced part in the pre-drilled hole, piston rods of the hydraulic cylinders push the compaction plates to extend out through the connecting rod frame and extrude the wall of the pre-drilled hole so as to form a compacted pre-drilled hole, and then cement mortar is injected. The steps are repeated to form a transverse composite foundation at the damaged part of the roadbed, and quick existing roadbed reinforcement is completed. By adopting the reinforcement method, the bearing capacity difference of the existing roadbed afterreinforcement is decreased to the greatest degree, and a bearing effect is uniform. The bearing capacity of the existing roadbed is improved by about 40-55%.
Description
technical field [0001] The invention belongs to the technical field of railway line maintenance, and relates to a device used in strengthening existing line bases, in particular to a rapid compacting and strengthening device for existing line bases; the invention also relates to a method for rapidly reinforcing existing line bases with the device . Background technique [0002] As the direct structure bearing the static load of the track and the dynamic load of the train, the state of the subgrade directly affects the smooth state of the rail. If the smoothness of the track is not good, it will cause severe vibration of the rolling stock, double the force of the wheel and rail, seriously damage the track and locomotive components, and even cause the train to derail and overturn, endangering the safety of driving. Therefore, the stability of the subgrade is the basis for ensuring the safe operation of trains. Railway engineering is a typical linear earth-rock structure, whi...
