Description
Technical field
The invention belongs to the construction method fields such as the mountain ridge, highway, railway, tunnel, have and are related to a plurality of intersection mountain ridge highway Design of Railway Tunnel construction method.
Background technique
China's comprehensive traffics such as highway, railway development at this stage is very fast, and mountain highway railway tunnel crossings on different level phenomenon increases It is more, when massif geology is general and closely intersects, how to handle the construction of a plurality of intersection mountain ridge road and rail Tunnel Design and ask Topic? it is just avoided that new highway the risk of tunnel construction and improves operation vcehicular tunnel stress, a plurality of intersection mountain ridge road and rail Tunnel Design construction method is exactly to be unfolded around this target.
Summary of the invention
The present invention is easy to ignore stratum for existing mountain ridge road and rail tunnel crossings on different level processing method and tunnel is mutual The structure mechanics analysis of effect lacks macro qualitative analysis control method, provides and a kind of a plurality of intersects the mountain ridge, highway, railway, tunnel Construction method.
The technical solution adopted by the present invention to solve the technical problems is: a kind of a plurality of intersection mountain ridge road and rail tunnel Design and construction method, includes the following steps:
(1) technology and substance prepare before tunnel cross passes through:
The secondary lining pre-add of existing vcehicular tunnel is carried out in strict accordance with Tunnel Design job specfication and shotfiring safety regulation Gu and new highway Tunnel Blasting and supporting construction safety etc. technologies and substance preparation, make entire construction teams and tunnel object Matter prepares to be in good state；
(2) have vcehicular tunnel secondary lining pre-reinforcement:
Within the scope of the longitudinal 60~70m of existing vcehicular tunnel secondary lining of tunnel crossings on different level lower part, every 50~ 100cm pastes wide 20cm, on thickness 6~8mm steel plate to existing vcehicular tunnel secondary lining using MPC glue or epoxy concrete, right Existing vcehicular tunnel secondary lining carries out pre-reinforcement, prevents the adverse effect of new highway tunnel strengthening segment blast working；
(3) new highway tunnel excavation control explosion design and construction:
On tunnel crossings on different level top, new highway tunnel excavation carries out control explosion design and construction, according to " shotfiring safety Regulation ", maximum allowable vibration velocity < 10cm/s of traffic tunnel, COMPREHENSIVE CALCULATING the result shows that: it is new on existing vcehicular tunnel top Build before and after vcehicular tunnel strengthening segment in each 15m (i.e. 60~70m) range, planning vcehicular tunnel intersect within the scope of 60~70m with The full face tunneling of 1.0m drilling depth or 1.5m drilling depth bench excavation, the control of single hop dose meet above-mentioned requirements in 5kg；
(4) preliminary bracing is carried out in time during new highway tunnel excavation, and carry out strengthening segment construction:
New highway tunnel 1.0~2.0m of every excavation in top just carries out preliminary bracing in time, it is ensured that top new highway tunnel Road adjoining rock stability carries out new highway Tunnel Second Lining in the case of closely following preliminary bracing by regulation；
Having 30~40m range above vcehicular tunnel and is planning that it is new to carry out top for 60~80m range above vcehicular tunnel Build vcehicular tunnel strengthening segment secondary lining reinforced concrete inverted arch stringer combination structure；
(5) operation tunnel monitors:
On top new highway tunnel strengthening segment intersect 60~70m range construction period and planning vcehicular tunnel intersect 60~ 70m range construction period needs to be monitored operation tunnel structure safely；
According to calculated result, Blast Vibration Monitoring is taken to operation tunnel structure；Operation tunnel intersects 60~70m model It encloses, secondary liner structure presses 5 measuring points of normative arrangement every 20m, if the vibration that operation tunnel secondary liner structure monitors Speed>5cm/s, newly built tunnels construction should take buffer blasting measure, i.e. reduction tunnel excavation drilling depth<1.0m, reduce single hop Dose < 5kg.
Preferably, in the step (3) traffic tunnel maximum allowable vibration velocity < 5cm/s.
Beneficial effects of the present invention are mainly manifested in: 1) being conducive to improve existing vcehicular tunnel stress, and be conducive to keep away Planning-free highway tunnel construction risk and rectifying plan vcehicular tunnel stress.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment 1:(1) tunnel cross passes through preceding technology and substance prepares
Existing vcehicular tunnel secondary lining pre-reinforcement is carried out in strict accordance with Tunnel Design job specfication and shotfiring safety regulation With technologies and the substance preparation such as new highway Tunnel Blasting and supporting construction safety, make entire construction teams and tunnel substance Prepare to be in good state.
(2) have vcehicular tunnel secondary lining and carry out pre-reinforcement
Have within the scope of the longitudinal 60~70m of vcehicular tunnel secondary lining in tunnel crossings on different level lower part, every 50~ 100cm pastes wide 20cm, on thickness 6~8mm steel plate to existing vcehicular tunnel secondary lining using MPC glue or epoxy concrete, right Existing vcehicular tunnel secondary lining carries out pre-reinforcement, prevents the adverse effect of new highway tunnel strengthening segment blast working.
(3) new highway tunnel excavation control explosion design and construction
On tunnel crossings on different level top, new highway tunnel excavation carries out control explosion design and construction, according to " shotfiring safety Regulation " (GB6722-2011), maximum allowable vibration velocity < 10cm/s of traffic tunnel, operation many years vcehicular tunnel suggestion control Vibration velocity < 5cm/s processed, COMPREHENSIVE CALCULATING the result shows that: it is each before and after existing vcehicular tunnel top new highway tunnel strengthening segment In 15m (i.e. 60~70m) range, planning vcehicular tunnel intersect within the scope of 60~70m with the full face tunneling of 1.0m drilling depth or 1.5m drilling depth bench excavation, the control of single hop dose meet above-mentioned requirements in 5kg.
(4) preliminary bracing is carried out in time during new highway tunnel excavation, and carry out strengthening segment construction
New highway tunnel 1.0~2.0m of every excavation in top just carries out preliminary bracing in time, it is ensured that top new highway tunnel Road adjoining rock stability carries out new highway Tunnel Second Lining in the case of closely following preliminary bracing by regulation；
Having 30~40m range above vcehicular tunnel and is planning that it is new to carry out top for 60~80m range above vcehicular tunnel Build vcehicular tunnel strengthening segment secondary lining reinforced concrete inverted arch stringer combination structure, be conducive to improve existing vcehicular tunnel by Power, and be conducive to avoid planning highway tunnel construction risk and rectifying plan vcehicular tunnel stress.
(5) operation tunnel monitors
On top new highway tunnel strengthening segment intersect 60~70m range construction period and planning vcehicular tunnel intersect 60~ 70m range construction period needs to be monitored operation tunnel structure safely.According to calculated result, need to operation tunnel Structure takes Blast Vibration Monitoring.Operation tunnel intersects 60~70m range or so, and secondary liner structure presses specification cloth every 20m 5 measuring points are set, if vibration velocity > 5cm/s that operation tunnel secondary liner structure monitors, newly built tunnels construction should be taken Buffer blasting measure, i.e. reduction tunnel excavation drilling depth < 1.0m, reduce single hop dose < 5kg.
