Abstract

The present invention is specially the construction method of the large-scale molten type solution cavity that collapses of a kind of Tunnel Passing, solves existing tunnel and passes through large-scale solution cavity and exist and waste time and energy and easily cause the problem of personal injury.The tunnel of a, the excavation solution cavity left and right sides; B, set up Bailey truss as operation platform in both sides, tunnel; C, look for top to remove danger stone after, adopt in time C25 silk fiber concrete to carry out just spraying operation, after completing, carry out spray anchor protection; D, employing wire rope are laid along solution cavity hole wall, wire rope completely spread Brooker net and are connected with wire rope; E, hole, molten chamber wall easily cave in deathtrap adopt round log carry out support top; Arrange a monitoring measurement section along interval, tunnel trunk direction within the scope of f, solution cavity, be encrypted layout; G, the deposit process of solution cavity bottom, solution cavity lower concrete is built; H, removal Bailey truss and protective screening, carry out tunnel top excavation.What the invention solves that to differ in size easily appear in solution cavity top falls block phenomenon and cannot carry out the difficult problem of construction operation bottom the solution cavity caused.

Description

The construction method of the large-scale molten type solution cavity that collapses of Tunnel Passing

Technical field

The present invention relates to method for tunnel construction, be specially a kind of Bailey truss that utilizes as the construction method of the large-scale molten type solution cavity that collapses of Tunnel Passing of job platform.

Background technology

The large-scale solution cavity of Tunnel Passing be in the past all adopt solution cavity under ground portion adopt pile foundation, pile foundation is built steel and concrete structure cushion cap, bottom is made to form an entirety, such construction method wastes time and energy, and block phenomenon easily appears falling in the top of solution cavity, the safety of constructor is threatened.

Summary of the invention

The present invention passes through large-scale solution cavity and exists to solve existing tunnel and waste time and energy and easily cause the problem of personal injury, provides the construction method of the large-scale molten type solution cavity that collapses of a kind of Tunnel Passing.

The present invention adopts following technical scheme to realize: the construction method of the large-scale molten type solution cavity that collapses of Tunnel Passing, adopts the tunnel of following steps: a, the excavation solution cavity left and right sides; B, first set up Bailey truss in side, tunnel, utilized the rock and roll that arranges bottom Bailey truss or flat rolling that Bailey truss is passed through the opposite side of solution cavity to tunnel, fix Bailey truss as operation platform in the left and right sides, tunnel; C, leave and take section situation by mapping, after looking for top to remove danger stone, adopt C25 silk fiber concrete to carry out just spraying operation in time, after completing, carry out spray anchor protection; D, employing wire rope are laid along solution cavity hole wall, wire rope completely spread Brooker net and are connected with wire rope; E, hole, molten chamber wall easily cave in deathtrap adopt round log carry out support top; Arrange a monitoring measurement section along interval, tunnel trunk direction within the scope of f, solution cavity, according to country rock situation, layout is encrypted to unstable region; G, the deposit process of solution cavity bottom, solution cavity lower concrete is built; H, removal Bailey truss and protective screening, carry out tunnel top excavation.

The construction method of the large-scale molten type solution cavity that collapses of Tunnel Passing of the present invention, what solve that to differ in size easily appear in solution cavity top falls block phenomenon and cannot carry out the difficult problem of construction operation bottom the solution cavity caused, and construction method reasonable benefit/risk, efficiency of construction significantly promotes.

Detailed description of the invention

The construction method of the large-scale molten type solution cavity that collapses of Tunnel Passing, adopts the tunnel of following steps: a, the excavation solution cavity left and right sides; B, first set up Bailey truss in side, tunnel, utilized the rock and roll that arranges bottom Bailey truss or flat rolling that Bailey truss is passed through the opposite side of solution cavity to tunnel, fix Bailey truss as operation platform in the left and right sides, tunnel; C, leave and take section situation by mapping, after looking for top to remove danger stone, adopt C25 silk fiber concrete to carry out just spraying operation in time, after completing, carry out spray anchor protection; D, employing wire rope are laid along solution cavity hole wall, wire rope completely spread Brooker net and are connected with wire rope; E, hole, molten chamber wall easily cave in deathtrap adopt round log carry out support top; Arrange a monitoring measurement section along interval, tunnel trunk direction within the scope of f, solution cavity, according to country rock situation, layout is encrypted to unstable region; G, the deposit process of solution cavity bottom, solution cavity lower concrete is built; H, removal Bailey truss and protective screening, carry out tunnel top excavation.

In specific implementation process, it is 5cm that concrete just sprays thickness, and spray anchor protection adopts φ 25 hollow grouting anchor, spacer ring × indulge as 1.0m × 1.0m interlaced arrangement, φ 8 reinforced mesh is the spacing 0.5m of 20cm × 20cm, wire rope, and each section monitoring parameter measuring point circumferential distance is arranged according to 5m.
