Embodiment 1

[0031] Such as Figure 1-2 As shown, this embodiment provides a multi-purpose simple platform for a two-lane tunnel, including a door frame, a platform structure and a spraying device.

[0032] The door frame is mainly composed of 16# channel steel lapped frame beams and bolted. The size of the 16# channel steel is 160mm×65mm×8.5mm. Door frame is made up of four parts such as column 18, beam, longitudinal beam, diagonal brace 17. Column 18, crossbeam and longitudinal beam are welded into a square with double 16# channel steel buckles, and the size is 160mm×130mm×8.5mm. Diagonal brace 17 uses single channel steel.

[0033] The mast is 7.4m high, 7.3m wide and 5m long. Two 5m long longitudinal beams are arranged at the bottom, and four columns 18 are welded on the bottom beams. Two beams and longitudinal beams are set on the top, and two more beams and longitudinal beams are set at 4.9m to ensure the rigidity of the platform. The headroom for traffic is 4.9m high and 3m wide...

Abstract

The invention discloses a multi-purpose simple rack for a double-line tunnel, and relates to the technical field of tunnel construction equipment. The multi-purpose simple rack comprises a portal frame, a platform structure and a spraying device, wherein the platform structure is arranged on the portal frame, and the spraying device is used for spraying water into the tunnel. The multi-purpose simple rack is simple in structure, the use is convenient and fast, and the multi-purpose simple rack requires low on the technical level of operators; the maintenance of the multi-purpose simple rack issimple and convenient, the multi-purpose simple rack can be maintained at any time, the water curtain is uniform, and the multi-purpose simple rack can ensure that the concrete surface is always in awet state, no dead corners exists, and no omission is caused. The problem of cracking and not maintaining in place of the secondary lining concrete surface is solved; the waterway is arranged in a profile modeling mode along with the tunnel face, the adaptability is high, and the rack has the functions of assisting in knocking inspection and defect remediation at the same time. A good work platform is provided for the operator, the durability is good, the maintenance is convenient, and the tunnel construction operation is not influenced; compared with a steam curing trolley which is expensivein manufacturing cost, the rack is lower in cost and easier to popularize and use, the equipment is reduced in the tunnel, the line of sight is good, and the passage of a transport vehicle and the intervisibility of the measurement radiation are facilitated.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a multi-purpose simple platform for a double-track tunnel. Background technique [0002] In order to ensure the safety of high-speed rail, the quality of the secondary lining concrete is the key point in the current construction management process. Due to the large section of the double-lane tunnel (about 150m 2 ), in the existing construction, the maintenance of the second lining concrete of the tunnel is generally not in place. Generally, high-pressure water guns are used for watering and curing, ranging from 3 to 5 times a day. However, due to the high temperature in the tunnel, after 20 minutes of watering, the concrete The surface will return from wet to dry state, which cannot meet the curing conditions for keeping the concrete surface wet all the time. If the curing quality is not up to standard, it will seriously affect the strength of concrete. ...
