Description

Technical Field

[0001] The utility model relates to the technical field of underground soil nail anchor obstacle clearing devices, in particular to an obstacle clearing device for an underground continuous wall construction trenching machine. Background Art

[0002] Existing ground-anchored wall construction processes underground soil nails before trenching, due to a lack of specialized processing equipment. Excavation is typically performed to the soil nail anchor point, followed by personnel entering the trench to cut the anchors. The typical depth of soil nails in municipal engineering projects requires a lengthy pre-cutting preparation process. Pre-treating excavation and subsequent backfilling for trenching are prone to trench wall collapse. Furthermore, manual cutting requires thermal or mechanical excision, which increases construction risk and significantly impacts trenching efficiency.

[0003] How to develop an obstacle-clearing device for underground continuous wall construction trenching machines to shorten the construction period, effectively avoid the risk of soil collapse on both sides of the trench during manual processing, improve construction safety and reliability, and reduce resource investment has become a technical problem that technical personnel in this field urgently need to solve.

[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] like Figure 1 As shown, an underground continuous wall construction trenching machine obstacle clearing device includes a connecting flange 3, the upper end of the connecting flange 3 is fixedly connected to the trenching machine frame through a bolt assembly, and the lower end of the connecting flange 3 is fixedly connected to the top of the cutting head box 4.

[0016] Specifically, a hydraulic transmission box 5 is installed inside the cutting head box 4 , a cutting head 6 is installed at the bottom opening of the cutting head box 4 , and the hydraulic transmission box 5 is transmission-connected to the cutting head 6 .

[0017] Specifically, it also includes a hydraulic pipeline 1 and an electrical pipeline 2. The hydraulic pipeline 1 and the electrical pipeline 2 both pass through the cutting head box 4 and are connected to the hydraulic transmission box 5. The other ends of the hydraulic pipeline 1 and the electrical pipeline 2 are connected to the original grooving machine grab head hydraulic pipeline. The hydraulic transmission box 5 provides power for each cutting head to perform cutting operations. The speed of the cutting head can be controlled by the original hydraulic grab control device to control the flow of hydraulic oil.

[0018] The hydraulic transmission box 5 and the cutting head 6 are pre-installed in the cutting head box 4; when working, first remove the original grab head through the flange connection plate, then install the cutting head box 4 on the slotting machine frame through the connecting flange 3 and the bolt assembly, and finally connect the hydraulic pipeline 1 and the electrical pipeline 2 to the slotting machine grab head box; Among them, the hydraulic and electrical pipelines of the hydraulic transmission box 5 have been installed when the cutting head box 4 is manufactured, and the electro-hydraulic controller is the original slotting machine grab head control device. After installation and debugging are completed, the obstacle removal operation can be carried out;

[0019] When replacing the cutting head, it is only necessary to connect the hydraulic pipeline and the electrical system of the hydraulic pump station. The replacement process is simple and fast, which greatly reduces the labor intensity. The preparation work for the clearance operation, equipment replacement, and debugging are all carried out on the ground, which improves the safety and reliability of construction. The operation is simple, convenient, and fast, and requires less manpower. Furthermore, it causes less disturbance to the surrounding soil, reduces the risk of trench wall collapse caused by conventional treatment methods with multiple processes and long construction time, and avoids the safety risk of cutting personnel entering the trench, improves the on-site working environment, and shortens the construction period.

[0020] Taking trench construction as an example, after the guide wall is completed, the underground obstacle area is excavated to the obstacle surface. The cutting head can be replaced simultaneously. The soil nail anchor cables are immediately cut after excavation is completed. After cutting a portion, the excavator is used to clear the next obstacle surface, and the work is continued until the obstacle is cleared. Each clearance saves four workers and reduces the construction cycle by 80% compared to manual clearance.
