Description
Technical field
The utility model relates to technical field of tunnel construction, specially a kind of to add for bias small-clear-distance tunnel surface grouting
Clamped support structure.
Background technique
China is the country on mountain more than one, and 75% or so territory is massif or hills, builds the process of development in highway
In, it constructs the geological conditions encountered and the increasingly sophisticated and conventional highway of construction environment is built in the area of southern abundant rainfall,
Natural landscape can be seriously destroyed, landslide landslide and soil erosion are caused.Under new era conditions, country for environmental protection and
Green construction is paid attention to increasingly, therefore overcomes geological conditions and construction environment difficulty and make great efforts to improve Highway Tunnel Construction science and technology
It is horizontal to become the two big most important things in the following highway tunnel construction with realization green construction, environmental protection construction as much as possible.
Small-clear-distance tunnel has the advantages that the simple project cost of construction technology is saved relative to multiple-arch tunnel, while relative to
Common separation formula tunnel can increase the freedom degree of route again, reduce the scale of separated subgrade, reduce opening for tunnel portal
Project amount is dug, is good for the environment.Due to these advantages that small-clear-distance tunnel has, the mountainous terrain high speed of fast development in recent years
In Highway Construction Project Based, the tunnel using small interval form is more and more, and has achieved good social benefit and economic effect
Benefit is mostly especially Unfavorable geology in south, and shallow embedding Unfavorable geology large section neighborhood-tunnel into hole is captured in work progress
Technical problem important means.And " zero excavates " is used into hole, reduce brought by constructing to the maximum extent to ecology
The disturbance of environment maintains original ecological balance as far as possible.
Tunnel all brings great difficulty by country rock location, to design and construction, to pass through, it is ensured that safety most has
One of method of effect is exactly to carry out grouting and reinforcing to country rock.It is exactly that the slurries with certain setting time are infused with the means of force feed
Enter into loose soil bed perhaps water-bearing stratum crack after grout cures with the soil particle or rock bonding of surrounding together, makes
The character of country rock is improved, and this method is known as slip casting method.With regard to wall rock grouting reinforcing for, have tunneling boring front pre-grouting,
Advanced tubule pre-pouring grout and radial grouting, local slip casting, surface grouting etc..These methods produce deformation controlling for rock surrounding gateways
Positive effect is given birth to, wherein tunneling boring front pre-grouting, advanced tubule pre-pouring grout, which are reinforced, is used as advanced pre-reinforcement technology, to steady
Determining face has very big effect.Radial grouting, local slip casting, surface grouting etc. are then grouting behind shaft or drift lining method for strengthening, i.e., according to tunnel
Monitoring and measurement data after road excavation, takes corresponding grouting and reinforcing according to deformation, plays the role of deformation controlling for rock surrounding gateways.
But radial grouting and surface grouting are time-consuming and laborious, local slip casting can only be directed to subrange grouting and reinforcing, and carry out supporting
When be not easy to carry out support construction to increase and carry out supporting operation, support construction be also not easy to carry out after slip casting it is mobile under
The operation in one region.
Based on this, the utility model devises one kind and reinforces support construction for bias small-clear-distance tunnel surface grouting, with
It solves the above problems.
