Abstract
The utility model discloses a reverse construction stepped excavation trestle, which comprises a first layer of trestle and a multi-layered lower trestle below the first layer of trestle, which are arranged along the depth direction of a reverse construction area from up and down, wherein the first layer of trestle and the multi-layered lower trestle are extended towards the center of a reverse construction excavation area from up and down layer by layer, so a stepped structure is formed, and the lower layer of trestle is arranged on a beam and slab structure of a basement. The utility model utilizes the beam and slab structure of the basement, so the excavation trestle in the reverse construction presents in a stepped mode, the excavation construction has no limitation on layer height, only small-sized equipment is adopted to complete the excavation construction, and the excavation efficiency is high.
Description
Technical field
The utility model relates to building underground engineering construction technical field, particularly a kind of stepping type shoveling trestle that is used for adverse construction method.
Background technology
Conventional adverse construction method is owing to the restriction of underground structure floor height, and the shoveling trestle generally can only be chosen in the structure first floor, and the earthwork that cutting depth is bigger needs large-scale shoveling equipment, and excavation efficient is lower.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of shoveling efficient height, and goes for the adverse construction method stepping type shoveling trestle that whole underground structure is cut the earth to be needed, to overcome the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of adverse construction method stepping type shoveling trestle, it is characterized in that, it comprises first floor trestle and the multilayer lower floor trestle that is arranged on first floor trestle below from top to down along the contrary regional depth of doing, successively stretch from top to bottom between the trestle of first floor trestle and multilayer lower floor to the contrary shoveling regional center of doing, form the stepping type structure, lower floor's trestle is arranged on the beam and slab structure of basement.
By above disclosed technical scheme as can be known, the utility model is by utilizing the beam and slab structure of basement, make the shoveling trestle in the adverse construction method be stepping type, the digging construction does not have the restriction of floor height, adopts small-sized shoveling equipment can finish digging construction, shoveling efficient height, adopt the utility model stepping type shoveling trestle, the shoveling efficient of conventional adverse construction method is improved more than 2 times, solved that trestle can only be positioned at the structure first floor in the conventional adverse construction method, the inefficient problem of cutting the earth.
Description of drawings
Fig. 1 is the utility model shoveling trestle structural representation.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model adverse construction method stepping type shoveling trestle, it comprises first floor trestle 1 and the multilayer lower floor trestle 2 that is arranged on first floor trestle below from top to down along the contrary regional depth of doing, successively stretch from top to bottom between the trestle 2 of first floor trestle 1 and multilayer lower floor to the contrary shoveling regional center of doing, form the stepping type structure, lower floor's trestle 2 is arranged on the beam and slab structure 3 of basement.
The beam and slab structure at described lower floor trestle 2 places is provided with reinforcement.
Claims (2)
1. adverse construction method stepping type shoveling trestle, it is characterized in that, its edge is against making the multilayer lower floor trestle (2) that regional depth comprises first floor trestle (1) from top to down and is arranged on first floor trestle below, successively stretch from top to bottom between the trestle (2) of first floor trestle (1) and multilayer lower floor to the contrary shoveling regional center of doing, form the stepping type structure, lower floor's trestle (2) is arranged on the beam and slab structure (3) of basement.
2. adverse construction method stepping type shoveling trestle according to claim 1 is characterized in that the beam and slab structure that described lower floor trestle (2) is located is provided with reinforcement.
