The utility model provides a sand stratum tunnel excavation method, this kind of sand stratum's main component gravel and sand (and a small amount of clay) use the tunnel shield tunneling equipment that embodiment 1 shows, when excavating the tunnel in the sand stratum, can open a hole in the section of thick bamboo bottom of boring section of thick bamboo 4, then connect a pipe that takes out the negative pressure on this section of thick bamboo bottom department hole again, still take the direction as shown in figure 2 as the example, when the excavation is tunneled from right to left in the sand stratum to whole device, take out the negative pressure to boring section of thick bamboo inside to boring section of thick bamboo to taking out the pipe that takes out the negative pressure, gravel and earth in the stratum can be taken into boring section of thick bamboo by the negative pressure in this way, resistance when boring section of thick bamboo from right to left tunnelling can be reduced, the tunneling speed of whole tunnel is accelerated.
The slide plate 8 in this embodiment may have only one through hole or may have a plurality of through holes.
Example 3
A tunneling method of a weak water-rich stratum.
In some weak water-rich stratum, the traditional tunnel excavation method is to freeze all soil of the area to be excavated together by adopting a freezing method to form a huge frozen block, and then excavate a tunnel in the frozen soil by adopting a drilling and blasting method.
In this embodiment, the tunnel shield tunneling device as shown in embodiment 1 is adopted, soil in a region to be excavated is frozen completely, then the device is utilized to excavate, the direction shown in fig. 2 is still taken as an example, the drill cylinder 2 and the positioning rod 3 (together with the positioning drill 7) are tunneled and excavated from right to left, on one side, frozen soil continuously enters the drill cylinder in the excavation process, after the tunnel excavation is completed, the positioning rod and the positioning drill are removed, the drill cylinder is left in the frozen soil layer, then the whole drill cylinder is settled in the frozen soil layer, after all the frozen soil is frozen, the bottom of the drill cylinder is removed, the whole drill cylinder is detached into a cylindrical shape to be reserved in the soil body as a permanent supporting structure, and muddy water in the drill cylinder is cleaned.
The tunnel excavation in the weak water-rich stratum is required to be frozen firstly, and unless the soil is firstly excavated from the ground surface and backfilled after the tunnel engineering is built, the soil is collapsed due to the fact that the water content of the soil is too large and the strength is insufficient even if the shield machine is used for excavation.
The length of the tunnel excavated in the method is required to be shorter than the length of the drill pipe when the length of the drill pipe is required to be specifically described, and if the length of the drill pipe is 100 meters, the length of the tunnel excavated by the method is 50-70 meters.
The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the application, but is intended to cover all equivalent modifications, direct or indirect, as applied to other related technical fields.
