Problems solved by technology

[0002] Excavation on the known road surface is used for laying the tunnel of various pipelines at present, for the convenience of construction, after the tunnel has been dug, it is necessary to install support plates and support bars in it to support both sides of the tunnel to prevent the tunnel from collapsing, and then Then in the tunnel for pipeline laying and other projects, the operation of installing support plates and support bars must be completed in the tunnel. Most of the geological structures in my country's coastal areas are soft foundation roads, quicksand layers or silt layers. Soft, or more quicksand, tunnel collapse accidents often occur, which are more likely to cause personal casualties of construction personnel, especially in the dismantling of tunnel support, the harm to construction personnel is more serious, and sometimes it is not easy to encounter In order to ensure the personal safety of the construction workers, the dismantled support facilities can only be abandoned in the tunnel. The result of this is the waste of timber resources and the increase of construction costs; in addition, due to the space in the tunnel Limited, it is not convenient for construction personnel to construct, prolongs the construction time, affects work efficiency, and the labor intensity of manual assembly and disassembly is high

Embodiment 1

[0053] For the situation that the open tunnel composite support device is used in general soil tunnels,

[0054] see Figure 1-Figure 11, Mingkai tunnel combination support device mainly includes: hoisting frame 1, metal structure split column 4, support plate placement frame 10, support plate 11, support bar assembly 12 and support plate extruder 14, etc. The hoisting frame includes: the four corners of the hoisting frame are symmetrically fixed with a lifting pulley 18 for connecting the metal structure split column hook 8 and a support plate placement frame 10, a lifting hook 2 and four manual winches 3 connected with the lifting hook. ; Its metal structure split column 4 comprises: the main column 9 that has installation groove in front, is welded on the side wing 5 that is equilateral triangle on both sides of main column, the split column hook 8 that is installed on the main column upper end and is welded on the installation The support bar placement frame 7 at the uppe...

Embodiment 2

[0071] When encountering tunnels with special soil quality, the structure of embodiment 1 is adopted for the tunnel composite support device.

[0072] The above-ground installation and operation method of the open tunnel combined support device includes the following steps:

[0073] When the tunnel is dug to a safe height, put a set of tunnel support assembly 15 assembled according to the above steps 1 to 5 into the dug tunnel, fasten the bolt 12-5 and the nut by the brace 12-4 Fasten the support bar assembly 12 and the metal structure split column 4, and continue to excavate the tunnel. When excavating to the collapsed part or the special soil such as quicksand layer, place the support plate 11 on this part, and then place the The spreader extruder 14 passes through the jack 6 of the spreader extruder, and is placed on the front side of the dug out spreader 11, and the adjustment bolt 14-1 of the spreader extruder is turned to make the spreader extruder The adjustment block ...

Abstract

The invention involves on a kind of bright mine combination support and protect installment and its the place the assembling and dismantling operating procedure, this equipment mainly includes: Above fixedly has the pulley, rises and falls the hook and manual hoists hangs jig, its two side are equipped with the flank and the extrusion jack metal structure fission column, the base plate laying aside frame, the base plate, supports the bar always to become as well as the base plate extrusion and so on, this combination support and protect installment gallery support and protect total Cheng Xianyu on installs, puts in digs in the gallery two opposites, then puts in the base plate and the base plate laying aside frame the combination support and protect always to become with the gallery two sides between, namely completes the gallery frame operation. The invention merit lies in: Because this combination support and protect installment installment and the disassemblage operation is carries on on the place, might fundamentally solve the person casualties event occurrence which created because of the gallery landslide, on constructed time-saving both and reduces effort, not only might enhance the construction efficiency, moreover also might reduce operator's labor intensity; Simultaneously has also solved the massive timber resources, reduces the construction cost.

Description

technical field [0001] The invention belongs to the technical field of pavement tunnel support, and in particular relates to an open tunnel combined support device and an above-ground assembly and disassembly operation method which can implement support assembly and disassembly operations in the tunnel on the ground and completely avoid personal casualties. Background technique [0002] Excavation on the known road surface is used for laying the tunnel of various pipelines at present, for the convenience of construction, after the tunnel has been dug, it is necessary to install support plates and support bars in it to support both sides of the tunnel to prevent the tunnel from collapsing, and then Then in the tunnel for pipeline laying and other projects, the operation of installing support plates and support bars must be completed in the tunnel. Most of the geological structures in my country's coastal areas are soft foundation roads, quicksand layers or silt layers. Soft, or...
