Abstract
The utility model discloses a kind of steel support structure that can realize Adjacent Pit synchronous construction, described Adjacent Pit is made up of station pit and tunnel foundation ditch, described station pit and described tunnel foundation ditch share space enclosing structure, described shared space enclosing structure comprises shared ground-connecting-wall, be provided with the n road station pit diagonal brace being positioned at described station pit bight in the side of described shared ground-connecting-wall, wherein n is greater than 2 integers being less than 4; In described tunnel foundation ditch, be provided with horizontal steel tube to support, it is characterized in that, be provided with the balance diagonal brace of station pit diagonal brace described in the n road being positioned at foundation ditch bight, described tunnel at the opposite side of described shared ground-connecting-wall.The utility model utilizes balance diagonal brace to provide counter-force to the space enclosing structure shared in tunnel foundation ditch, constructs again, can realize synchronous construction, can compress about 4 months duration after making open trench tunnel construction that station need not be waited to complete.
Description
Technical field
The utility model relates to a kind of foundation ditch braced structures, particularly a kind of steel support structure realizing Adjacent Pit synchronous construction.
Background technology
In city rail construction, due to the restriction of urban space, tunnel generally adopts shield construction, and area, rock stratum can adopt Mining Method, can adopt cut and cover tunneling in place open area such as the combination areas of city and country.The tunnel of cut and cover tunneling and subway station is adopted to form Adjacent Pit.The tunnel excavation degree of depth is suitable with the station degree of depth, and foundation ditch width has bigger difference, and support pattern also has difference, and two foundation ditches generally should front and back construction.According to general Metro Construction program, station of should first constructing, carries out the open-cut in tunnel again after topping out.For large-scale transfer station on the same stage, wherein a line adopts open cut, and another line adopts shield construction, the problem that traditional design can cause the duration longer.The working procedure of traditional design is: Metro Excavation station pit → constructing structure to first support → open trench tunnel foundation ditch (abolishing the ground-connecting-wall) → constructing structure that binds → remove simultaneously to binding → the accessory structure construction → shield-tunneling construction of open trench tunnel.Transfer station, because volume is large, complex structure, is generally the duration Controlling vertex of many subway lines, goes along with sb. to guard him or braced structures, realize the synchronous of two foundation ditches if can change, then can shorten the overall duration.
Summary of the invention
The utility model provides a kind of steel support structure that can realize Adjacent Pit synchronous construction for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: a kind of steel support structure that can realize Adjacent Pit synchronous construction, described Adjacent Pit is made up of station pit and tunnel foundation ditch, described station pit and described tunnel foundation ditch share space enclosing structure, described shared space enclosing structure comprises shared ground-connecting-wall, be provided with the n road station pit diagonal brace being positioned at described station pit bight in the side of described shared ground-connecting-wall, wherein n is greater than 2 integers being less than 6; In described tunnel foundation ditch, be provided with horizontal steel tube to support, be provided with the balance diagonal brace of station pit diagonal brace described in the n road being positioned at foundation ditch bight, described tunnel at the opposite side of described shared ground-connecting-wall.
Described balance diagonal brace has n-1 road, from top to bottom with station pit diagonal brace one_to_one corresponding described in n-1 road, and the most lower balance diagonal brace that described station pit diagonal brace is not corresponding with it together.
Balance diagonal brace described in per pass and comprise a reinforced concrete slab angle brace and a steel pipe diagonal brace, the sectional dimension of described steel pipe diagonal brace is identical to the sectional dimension supportted with described horizontal steel tube.
Described steel pipe diagonal brace is connected with described shared space enclosing structure by power transmission box.
The advantage that the utility model has and good effect are: in tunnel foundation ditch, utilize balance diagonal brace to provide counter-force to the space enclosing structure shared, and construct again, can realize synchronous construction, can compress about 4 months duration after making open trench tunnel construction that station need not be waited to complete; And then have compressed the life cycle of mechanical hoisting, can improve the work efficiency of hoisting transportation equipment, save lease expenses, rough estimate, can save lifting cost 600,000.Set balanced support is identical with the support absolute altitude of station pit diagonal brace, and stressed shortest path, to space enclosing structure without subsidiary stress, on space enclosing structure without impact.Compared with supporting with increase concrete, bracing members is easy for installation, and material can have enough to meet the need use, and can avoid the impact of later stage dismounting on space enclosing structure.With reserved back-pressure soil phase ratio, provide counterforce structure to take up room little, do not need excavation and construction point two stages, interval without impact on open cut.
