Abstract
The utility model patent is related to a kind of supporting construction for having and monitoring measurement function.The supporting construction mainly includes the anchor cable at top, and the anchor pole that anchor beam and its top are applied, outer layer gunite concrete, steel canopy, internal layer pours rubber grain concrete and monitoring chi with a scale.The anchor cable at top can pass to the load of tunnel surface country rock the rock mass of deep stability region, give full play to the bearing capacity of deep rock mass；Rubber grain concrete has compressibility, the deformation energy of release country rock that can be suitably；It is that with graduated ruler, the change that the deformation of tunnel surface country rock can be by monitoring chi scale is intuitively observed to monitor chi.The structure stress rationally, the function of tunnel surface rock deformation is measured with timely monitoring, with good engineering application value.Suitable for city underground engineering and underground support engineering.
Description
Technical field
The utility model is related to a kind of supporting construction for having and monitoring measurement function, and the structure can be widely used in city
Subway Surveying Engineering and underground support engineering, being particularly suitable for use in needs the engineering of the quick rock deformation of monitoring in time.
Background technology
City underground engineering and mine construction engineering by leaps and bounds develop, although current support technology develops also right and wrong
It is often rapid, but can't reach that it is required compared to engineering now.Traditional support engineering develops from single log hut supporting
To capplce, H-shaped steel supporting, concrete spraying support, the combined supportings such as anchor pole, anchor cable are then progressively developed into.As a whole,
Although traditional support pattern can reach the purpose for maintaining country rock basicly stable, the deformation condition of later stage country rock also needs to profit
Measured to obtain with local supervising and measuring equipment or personnel.This mode can bring some problems unavoidably, and construction procedure first is relative
Cumbersome, secondly workmen can not grasp supporting construction in time and apply the deformation condition of rear country rock and the stability in tunnel, because
This, construction procedure can either be reduced by needing a kind of new technology badly, can grasp the deformation condition of country rock in time again.Need invention one
Plant the new supporting construction for integrating construction and monitoring.
The content of the invention
The utility model is related to a kind of supporting construction for having and monitoring measurement function, and the structure can be widely used in city
The supporting of subway engineering and underground engineering, being particularly suitable for use in needs the engineering of the quick rock deformation of monitoring in time, monitors chi energy
The supporting effect of enough quick feedback supporting construction in time.
A kind of supporting construction that there is monitoring to measure function, is by anchor cable, anchor beam, steel canopy, rubber grain concrete, anchor
Bar, monitoring chi and first pneumatically placed concrete, it is characterised in that anchor cable and steel canopy overlap, anchor beam fixed with anchor pole and together with just
Pneumatically placed concrete is overlapped, and monitoring chi is embedded in rubber grain concrete, and rubber grain concrete is located at steel canopy and just spray
Between concrete.
Position is helped as an improvement, setting to carry scale and numerical value on 2 monitoring chis, monitoring chi and be arranged on two per section.
As an improvement, applying 5 anchor cables and 8 anchor poles per section.
As an improvement, anchor cable is using single beam resin anchoring anchor cable, diameter 15.24mm, length 8000mm, an array pitch
800 × 800mm, uses MSK/23 × 600mm type resin explosive rolls, volume/of consumption 1.
As an improvement, anchor pole is using high-strength screw-thread steel bolt diameter 18mm, length 2250mm, 800 × 800mm of array pitch,
Use MSK/23 × 600mm type resin explosive rolls, volume/of consumption 1.
Formed as an improvement, rubber grain concrete is uniformly mixed and stirred from C35 concrete with rubber grain.
As an improvement, monitoring chi is embedded into rubber grain concrete, and contacted with first pneumatically placed concrete.
The beneficial effects of the utility model are：It is a kind of that there is the supporting construction that monitoring measures function and traditional supporting construction
The mechanism of action is similar, and the parameter of supporting construction is determined according to drift section size.The structure is in roadway excavation injection at initial stage
Concrete prevents country rock from falling top, secondly pours rubber grain concrete using template and monitoring chi is embedded in into inside.Rubber
On the one hand the compressibility of grain concrete can discharge surrouding rock deformation energy, reduce the deformation to steel canopy；On the other hand prison can be coordinated
Control chi intuitively shows the deflection of country rock.The utility model will be constructed and is combined together with monitoring, can not only add
The fast construction period, additionally it is possible to timely and effectively monitor the stability of country rock.

Embodiment
Referring to Fig. 1, Fig. 2, it is described as follows：The utility model and traditional support construction technique are essentially identical, by opening
The area for digging section determines the supporting parameter of supporting construction, then according to being constructed successively from top to bottom shown in Fig. 1.Drift section is opened
Certain thickness concrete is first sprayed after digging ensures country rock not slump, then applies top anchor cable and the anchor pole in portion of side, and anchor beam leads to
Cross anchor pole to fix, then pour rubber grain concrete and embedded prefabricated monitoring chi, finally apply steel canopy.
A kind of supporting construction that there is monitoring to measure function, is by anchor cable, anchor beam, steel canopy, rubber grain concrete, anchor
Bar, monitoring chi and first pneumatically placed concrete, it is characterised in that anchor cable and steel canopy overlap, anchor beam fixed with anchor pole and together with just
Pneumatically placed concrete is overlapped, and monitoring chi is embedded in rubber grain concrete, and rubber grain concrete is located at steel canopy and just spray
Between concrete.
Position is helped as an improvement, setting to carry scale and numerical value on 2 monitoring chis, monitoring chi and be arranged at two per section
Put.
As an improvement, applying 5 anchor cables and 8 anchor poles per section.
As an improvement, anchor cable is using single beam resin anchoring anchor cable, diameter 15.24mm, length 8000mm, an array pitch
800 × 800mm, uses MSK/23 × 600mm type resin explosive rolls, volume/of consumption 1.
As an improvement, anchor pole is using high-strength screw-thread steel bolt diameter 18mm, length 2250mm, 800 × 800mm of array pitch,
Use MSK/23 × 600mm type resin explosive rolls, volume/of consumption 1.
Formed as an improvement, rubber grain concrete is uniformly mixed and stirred from C35 concrete with rubber grain.
As an improvement, monitoring chi is embedded into rubber grain concrete, and contacted with first pneumatically placed concrete.
