Problems solved by technology

Because the boards are long and heavy, it takes up to 5-7 people to carry and disassemble them, which consumes a lot of manpower; at the same time, the handling and disassembly of the boards is very time-consuming, and it takes about two days to complete a construction cycle, that is, 30 In addition, the existing slabs are made too thin in order to reduce weight and facilitate transportation, and the too thin slabs are easy to bend when pouring cement, resulting in uneven gutters or uneven widths

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0035] like figure 1 As shown, when constructing in the tunnel 1, it is necessary to put the left plate and the right plate into the ditch 2, and then pour cement into the gap 3 between the left plate and the right plate and the ditch wall, and remove it after setting The ditch of the target specification is obtained only by the left plate and the right plate.

[0036] For better construction, such as figure 1 , 2 , 3, 4 and 5, a tunnel ditch construction platform, including:

[0037] A support frame 5 that can move in the tunnel, the support frame includes left and right support rods (8, 9) and crossbeams 7 horizontally erected on the left and right support rods, and the lower ends of the left and right support rods (8, 9) are provided with The wheels 10 move in the tunn...

Abstract

The invention discloses a tunnel ditch construction platform, comprising: a support frame that moves along the extension direction of the tunnel ditch, the support frame straddles the ditch and a notch is opened on the crossbeam of the support frame; a left plate and a right plate In the formed model, the left plate and the right plate are respectively suspended under the crossbeam through the adjusting piece, and the adjusting piece passes through the notch and can move left and right along the notch to adjust the relative distance between the left plate and the right plate. The support frame of the present invention makes it easier to carry and move the left plate and the right plate, and at the same time, it is easier to adjust the distance between the left plate and the right plate, so that the left plate and the right plate form a model consistent with the preset ditch width, and the model’s Rapid construction is more conducive to pouring outside the model in the later stage, thus improving the efficiency of ditch pouring and reducing manpower consumption.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, and more specifically, the invention relates to a tunnel ditch construction stand. Background technique [0002] During the construction of the tunnel, a trench will be left after the bottom of the tunnel is poured with cement. The trench needs to be poured again to obtain a ditch with a suitable size. The ditch can be used for wiring or drainage. The existing construction The method is to use two slabs of about 30 meters to place in the ditch. The slabs are vertical to build a model of the gutter, and then pour cement on both sides of the slab. After the cement hardens and sets, remove the slabs to obtain the gutter. Because the boards are long and heavy, it takes up to 5-7 people to carry and disassemble them, which consumes a lot of manpower; at the same time, the handling and disassembly of the boards is very time-consuming, and it takes about two days to complete a cons...
