The utility model discloses simple structure, convenient operation, the inside concrete watering layer that is provided with of support frame and mount is provided with a plurality of screws through setting up the mount through bolted connection, and the screw top is provided with the drill bit, is provided with the stand on the frame, the stand top links to each other with the mount, and the practicality is strong.
Description
Technical field
The utility model relates to building field, is specifically related to a kind of peace and tears easy support of tunnel fixed mount open.
Background technology
Tunnel portal excavation is intended adopting mechanical execution, and tunnel cutting uses simple and easy from assembly jig wagon drill eye, and multistage millisecond detonator is ignited, and in order to improve the Smooth Blasting Effects of periphery hole, periphery hole uses special detonator to ignite.Tunnel haulage adopts loader dress quarrel, and dump truck coordinates fortune quarrel.The secondary lining concrete placings in tunnel uses the monolithic large form chassis that length is 12m, and concrete is in blending station centralized mixing, and concrete transport vehicle transports, and is pumped into mould.The construction of avris ditch adopts combined steel formwork.And the layout of usual constructing tunnel temporory structure: owing to planning the single-ended driving at tunnel entrance, the temporory structure of constructing tunnel is arranged on the right side of tunnel exit.Be arranged in outside the right side roadbed of outlet according to hole orographic condition by air feed plant equipment, reservoir is located at the Dong Ding left side is about 80m position far from hole.After machinery is marched into the arena, carry out hole earthwork evacuation immediately, construction Ding Yang slope, hole catchwater and carry out facing upward slope shotcrete slope reinforcing, carry out into wide open preparation of digging.Hole excavation and reinforcing: adopt mechanical execution, excavating by Construction of roadway method, when digging to hole cubic meter of stone section, in order to reduce the disturbance of hole being faced upward to slope and roadbed side slope as far as possible, the method for weak blast or presplit blasting must be adopted to excavate.Hole is faced upward slope and is adopted shotcrete with wire mesh to reinforce, and enters hole in order to safety.The excavation and support of the shallow reason section of hole country rock: construction method adopts benching tunnelling method construction, top bar and adopt advanced hollow grouting anchor, upper arc guide hole circle-digging stays core local method, excavate every cyclic advance identical with shaped steel arch spacing, preliminary bracing is applied in time after excavation, excavation of getting out of a predicament or an embarrassing situation lags behind the 8 ~ 10m that tops bar, and applies preliminary bracing and inverted arch in time after excavation, then carries out grouting and reinforcing to interval pillar.
The fixing pre-buried type that usually adopts at present for the support frame in tunnel portal digging process is fixed, and is exactly first excavate hole then fluid concrete, and in concrete embedded anchor bar, implement construction after then waiting concrete setting.This traditional scheme is time-consuming quite serious, and construction cost is not low yet.
Utility model content
