It penetrates anchor pole to arrange and expose in hanging vertical shaft obliquely at the top of tunnel, be equipped in the hanging vertical shaft in vertical shaft bottom
The template in portion has poured blocking concrete, and exposing section of the anchor pole in hanging vertical shaft is penetrated described in blocking concrete package.
The shuttering supporting is on formwork support structure, and formwork support structure is fixed on through fixing anchor bar at the top of tunnel, institute
State that fixing anchor bar is fixed at the top of tunnel and its lower end is exposed, fixing anchor bar exposed junction is welded and fixed with formwork support structure.
The anchor pole that penetrates is evenly arranged at the top of tunnel using hanging Shaft bank center on several circles in the center of circle, to wear
Vertical shaft axis is directed toward in oblique top to saturating anchor pole at an angle.
The anchor pole that penetrates is directed toward vertical shaft axis in the oblique top of 45° angle.
The anchor pole that penetrates is evenly arranged at the top of tunnel using hanging Shaft bank center as on two circles in the center of circle, two
The distance of circle and hanging Shaft bank is respectively 1.5m and 2.5m.
The fixing anchor bar be arranged in around hanging Shaft bank, it is parallel with hanging vertical shaft axis.
The formwork support structure is made of several main support dowels being criss-cross arranged and auxiliary support dowel,
Main and auxiliary support dowel both ends are weldingly connected with the corresponding fixing anchor bar.
The beneficial effects of the utility model are：Anchor pole is penetrated in the utility model reversely to apply to hanging vertical shaft out of tunnel
Work can not dispose main reinforcement in the joint bar that solves the problems, such as can not to construct in hanging vertical shaft, concrete, make blocking concrete with enclosing
Rock is combined together, and improves the safety coefficient of blocking concrete.
Fixing anchor bar lower part is exposed in the utility model, simple in structure, easy for construction as the fulcrum of fixed form, solution
The fixation problem for silo bottom template of having determined.
The utility model arrangement and method for construction is simple and practicable, can be pre-buried in early period, also can in equipment constructions such as later-stage utilization cranes,
And short construction period, other positions are disturbed small.
Description of the drawings
Fig. 1 is the diagrammatic cross-section of embodiment.
Fig. 2 is the arrangement schematic diagram that anchor pole is penetrated in embodiment.
Fig. 3 is the scheme of installation of formwork support structure in embodiment.
Specific embodiment
As shown in Figure 1, the present embodiment is a kind of plugging structure of hanging vertical shaft, excavated in advance for blocking 2 top of tunnel
Hanging vertical shaft 1, hanging 1 diameter 3.5m of vertical shaft is advance by certain layout rules around the top of tunnel 2,1 well head of hanging vertical shaft
Anchor pole 5 and fixing anchor bar 3 are penetrated equipped with several, you can it is pre-buried early period in 1 stage excavation of tunnel, it can also be stepped on using crane etc. in the later stage
High equipment is implemented.
Anchor pole 5 is penetrated in the present embodiment in tunnel to implement, it is circumferentially disposed along hanging 1 periphery of vertical shaft, it is evenly arranged in tunnel
2 top of hole is enclosed using hanging 1 well head of vertical shaft as the two of the center of circle on circle.The distance of two circles and hanging 1 well head of vertical shaft is respectively 1.5m
And 2.5m, the axis (see Fig. 2) that anchor pole 5 is directed toward hanging vertical shaft 1 in the oblique top of 45° angle is penetrated, anchor pole 5 is penetrated on same circle circle
Spacing 1m or so, penetrates 5 length 4.5m of anchor pole, and its upper part penetrates hanging 1 borehole wall of vertical shaft and exposed.
This example sets to block the template 6 of hanging Shaft bank below hanging vertical shaft 1, and template 6 is supported in template branch
On support structure 4, formwork support structure 4 is fixed on 2 top of tunnel through fixing anchor bar 3.As shown in figure 3, formwork support structure 4 is by indulging
3 of horizontal interlaced arrangement main support dowels 41 and 1 auxiliary support dowel 42 form, main and auxiliary support dowel both ends with
Corresponding fixing anchor bar 3 is weldingly connected.Fixing anchor bar 3 is implemented in tunnel in this example, is arranged on hanging 1 periphery of vertical shaft, length
3m is constructed upwards by 2 crown of tunnel, and parallel with hanging 1 axis of vertical shaft, appear 20cm for lower part, and section is exposed in the lower part of fixing anchor bar 3
It is weldingly connected with formwork support structure 4.
Blocking concrete is poured using the template 6 below hanging vertical shaft 1 in hanging vertical shaft 1, blocking concrete package is worn
Saturating exposing section of the anchor pole 5 in hanging vertical shaft.It penetrates anchor pole 5 and can be used as blocking concrete steel bar stress, but also as country rock
Joint bar links together blocking concrete and hanging 1 country rock of vertical shaft.
The construction method of the present embodiment is as follows：
The first step in 2 stage excavation early period of tunnel, in the case of hanging 1 terrain clearance of vertical shaft is smaller, is pressed in tunnel 2
Certain rule penetrates anchor pole 5 and fixing anchor bar 3 to the construction of hanging 1 periphery of vertical shaft, also can according to circumstances be utilized after the completion of tunnel 1
Crane etc. ascend a height equipment implementation.
Second step, hanging vertical shaft 1 are appeared using the equipment of ascending a height such as loop wheel machine in 3 lower part of fixing anchor bar using after the completion of function
The main and auxiliary support dowel 41,42 of section welding, the formwork support structure 4 of the corresponding hanging vertical shaft 1 of composition.
Template 6 is inserted between 2 crown of formwork support structure 4 and tunnel in interspacing in advance, and is securely connected by the 3rd step, seals
Closed cycle side gap.
4th step pours downwards blocking concrete from hanging 1 top of vertical shaft.
