The groove support not only influences the progress and the quality of the project, but also directly relates to the life safety of field construction personnel. At present, different support methods such as slope excavation, plate type support excavation, channel steel support excavation, steel sheet pile support excavation and the like are mainly adopted in the field construction method.

The defects and shortcomings of the prior art are as follows:

1. slope releasing and excavating: the requirements of slope excavation on soil quality and excavation depth are high, the occupied area is large during slope excavation, and the applicability is poor in the current municipal road construction; meanwhile, the method has large excavated earth volume and increases construction cost.

2. Plate type supporting excavation: the plate type support is not suitable for digging a groove with the depth of more than 2 meters, requires sectional construction, is not suitable for long-distance continuous pipeline groove construction, and causes the discontinuity of a linear operation surface; often need the manual work to set up in the slot when setting up the support facility, increased constructor's safety risk.

3. Supporting by channel steel: the channel steel support has high noise, channel steel needs to be driven into the channel steel to be welded in the process, and the material consumption is serious; pile holes formed in the pile pulling process need to be backfilled, and the process is complicated.

4. Supporting with steel sheet piles: the steel sheet pile support has high requirements on the soil condition of a construction site, is difficult to drain water, and has large investment in material and machinery cost because pile holes formed in the pile pulling process need to be backfilled, so that the steel sheet pile support is not suitable for construction projects in narrow areas and with low investment.

Therefore, a groove slope support which is economical, practical, convenient to use, transport and process and meets different groove construction requirements is urgently needed.
