Description
Technical field
The present embodiments relate to technical field of tunnel construction, and in particular to a kind of manual imitation laying tunnel double-lining steel mesh
Construction method and be laid with rack.
Background technique
Well known, steel mesh laying is a heavy artificial work in tunnel double-lining concrete construction at present, danger
Dangerous height.
Tunnel double-lining steel mesh is laid at present: reinforcing bar is all by the way that after upper stage, manpower pushing tow is carried out to tunnel rock face
It is tied up.
Longitudinal reinforcement method divides step to stand on rack using hoist engine or operator, by the way of relay,
Longitudinal reinforcement is placed on rack.After circumferential reinforcement is laid in place, longitudinal tie up with circumferential direction connects into steel mesh.
Circumferential reinforcement laying is to be divided to two classes: a kind of tunnel double-lining circumferential reinforcement, since reinforcing bar is too long, beyond tunnel cross-section
Vertically, horizontal length can not vertically and horizontally lifted and put, have to first along tunnel, longitudinal direction is placed on ground.
In conventional construction, operator divides on step standing rack the side by the way of each single artificial relay and transmitted
Formula, reinforcing bar be along it is longitudinal with it is vertical it is vertical between certain angle oblique cutting enter, reinforcing bar forward along tunnel contour camber line helix
The approximately the same plane for finally progressivelying reach designated position forms circumferential reinforcement.Direction, angle are carried out to reinforcing bar during transmitting
The correction of degree, radian.The resistance that operator needs to overcome reinforcing bar downward, longitudinal direction move horizontally resistance and brake forming band
The resistance come when single steel bar connects into single ring with inverted arch embedded bar, and is connect not yet with other single steel bar rings
Networking, easily along tunnel, longitudinal direction collapses, and generates security risk.
Another kind of use other modes lift after prescinding circumferential reinforcement, are connected in tunnel close to scar position
It connects, tie point is more, and cost is higher, and uncontrollable factor is more, and the risk of high altitude operation is bigger, and effect is lower.Reinforcing bar simultaneously
Spacing can not manually be precisely controlled.
Summary of the invention
