Description
Technical field
This utility model relates to tunnel concrete pouring structure, and particularly a kind of Tunnel Second Lining vault is owed to dig place's teeming
Building structure.
Background technology
At present secondary lining (being called for short two linings) vault owes to dig needs when cutting again casting concrete, concrete chisel removal pattern
The most arbitrarily, vault is the highest, utilizes heavy chassis to support, reserve edge one during casting concrete during formwork reinforcement
Block template is not first installed, and after the concreting at other templates is good, at residue, concrete can only be manually put in by concrete
In template, then lift template and concrete is pressed into two lining gaps.Owing to being vault, masterplate is reinforced to be needed to utilize private station
The steel pipe scaffold system of car or reinforcing shores reinforcing template, and this reinforcement process is set up the most additional due to needs
System and expend substantial amounts of human and material resources, construction period is the longest.One piece of template must be reserved during casting concrete and pour coagulation
Soil, is easily caused concrete leakiness, does not reaches design strength, even causes cavity, does not reaches renovating effect.Therefore, it changes
Enter and innovate imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of tunnel two
Secondary lining cutting vault is owed to dig place's teeming building structure, can effectively solve the problem that the place's of digging casting concrete again owed by vault.
The technical scheme that this utility model solves is, a kind of Tunnel Second Lining vault is owed to dig place's teeming building structure, including
Being arranged on the preliminary bracing on country rock surface and be arranged on the secondary lining on preliminary bracing surface, secondary lining is owed the place of digging and is had bottom
Opening pour groove, pour big up and small down trapezoidal in the cross section of groove, its infraoral is coated with the template for sealing, in template
Being provided with hollow bolt, hollow bolt one end is stretched out outside template, the other end stretch into pour groove and through after preliminary bracing with enclose
Rock links together, pour have on the secondary lining at place, groove inclined-plane with pour that groove is connected pour passage, pour groove top
Inside and outside through injected hole is had on the hollow bolt sidewall of position, portion.
This utility model novel structure is unique, and advantages of simple easily operates, safe and reliable, time saving and energy saving, hollow bolt conduct
Can be used for again reinforcing template while reinforcement, simultaneously as slip casting passage, concrete compaction, nothing after again pouring are empty,
Reach design strength, easy to use, effective, it is the innovation on tunnel concrete pouring structure.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is upward view of the present utility model.
Fig. 3 is the use state diagram after this utility model casting concrete.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Being given by Fig. 1 to Fig. 3, this utility model includes that the preliminary bracing 2 being arranged on country rock 3 surface and the initial stage that is arranged on prop up
Protecting the secondary lining 1 on surface, what secondary lining 1 owed that the place of digging has a lower openings pours groove 4, pour the cross section of groove 4 present big under
Little is trapezoidal, and its infraoral is coated with the template 7 for sealing, and template 7 is provided with hollow bolt 6, and hollow bolt 6 one end is stretched
Going out outside template, the other end stretches into and pours groove and link together with country rock 3 after preliminary bracing 2, pours place, groove 4 inclined-plane
Secondary lining on have with pour that groove is connected pour passage 11, pour and have on the hollow bolt sidewall of groove tip position
Inside and outside through injected hole 6a.
For ensureing using effect, the outer surface of described template 7 is provided with steel pipe 8 in hollow bolt 6 both sides, and steel pipe 8 leads to
Crossing the butterfly card 9 being contained in successively on hollow bolt and clamp nut 10 is pressed on template outer surface, the reassembling type constituting template is solid
Fixed structure；
Being provided with grouted anchor bar 5 in described template 7, grouted anchor bar one end is stretched out outside template, and the other end stretches into and pours
Groove also links together with country rock 3 after preliminary bracing 2；
The outer surface of described template 7 is provided with steel pipe in grouted anchor bar both sides, and steel pipe is by being contained in grouted anchor bar successively
On butterfly card and clamp nut be pressed on template outer surface, constitute the reassembling type fixed structure of template；
The described angle pouring groove 4 hypotenuse and preliminary bracing surface is 55-65 °.
When this utility model uses, cut concrete owing the place of digging, then cut and invade the country rock that two shirt portion are divided, make this portion
Point constitute and up big and down small trapezoidal to pour groove, i.e. breach answers inner wide and outer narrow, pours and digs one on the secondary lining at place, groove inclined-plane
With pour that groove is connected pour passage, pour the square opening that passage is 10cm × 10cm, the finishing of square opening mouth rim is concordant,
Smoother, wall dabbing, then bore one to one by the position of hollow bolt and grouted anchor bar at the country rock pouring groove place
Eye, then installs hollow bolt, and at the injected hole 6a through inside and outside the position of preliminary bracing cuts one of hollow bolt,
Being used as the grouting in later stage, grouting rock bolt, then installation form are installed in both sides, and template covers the infraoral pouring groove, mould
Plate utilizes mounted anchor pole when reinforcing, then carry out conventional reinforcing by butterfly card, nut, steel pipe.Pass through after installing
Pour passage and carry out casting concrete, when finally pouring concrete at reserved passageway, owing to amount of concrete is few, concrete is put
In the template corresponding with pouring channel portal, then lift this template and concrete is pressed into gap, last fixed form,
Completing to seal, concrete strength utilizes hollow bolt after reaching design strength form removal, to Concrete Filled slip casting, finally will
The anchor pole cutting exposing concrete surface is smooth, as it is shown on figure 3, reference 12 is the concrete poured in figure.
Compared with prior art, this utility model novel structure is unique, and advantages of simple easily operates, safe and reliable, time saving and energy saving, pours
Groove is big up and small down, and hypotenuse plays the effect of lifting, and hollow bolt, as can be used for again reinforcing template while reinforcement, is made simultaneously
For slip casting passage, the concrete compaction after again pouring, nothing cavity, reach design strength, easy to use, effective, it is tunnel
Innovation on concrete pouring structure.
