Description
Technical field
The utility model relates to a kind of upright mine pit construction and uses device, especially relates to a kind of template of bellows-shaped.
Background technology
Generally when upright mine pit is constructed, adopt following several method:
(1) linked network anchor pneumatically placed concrete is done upright hole supporting while excavating, and sets up template, assembling reinforcement fluid concrete.Operation comparatively complexity and supporting can not guarantee 100% do not cave in.
(2) drop shaft sinking construction: adopt prefabricated concrete product, be transported to the job site, take the way of sinking behind the hoisted in position while excavating.Need large-scale transportation and hanging device, and the job site need possess the transporting and hoisting condition.
(3) large-sized upright hole (length and width greater than 7 meters deep foundation ditch) can adopt underground continuous wall construction method.Floor space is big, and equipment requires high.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the limitation that above-mentioned prior art exists, and design provide a kind of in light weight, intensity is high, easy to operate, transportation and storage is easy to the template of bellows-shaped, thereby can take more simple, safe, practical even need not the construction of fluid concrete.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of template of bellows-shaped, it is characterized in that, this template is an arc structure, the middle part of longitudinal section is 2～4 undulatory arc-shaped structures, the connection end face is set around the template, the connecting bolt hole is set on the end face, and two connection end faces are plane structure up and down, and this union end face width degree is identical with the ripple degree of depth of arc-shaped structure.
Preferred 3 of described arc-shaped structure.
Described two connection linearly structure of end face or convex structures up and down.
Compare with existing plane template, the utlity model has following advantage:
(1) in light weight: as to be to make, can manually to move with the book plate;
(2) intensity height: be designed to corrugated, have the rigidity and the intensity of excellence than the flat board of condition of equivalent thickness;
(3) easy to operate: a dead lift is convenient, connects with bolt during assembling;
(4) transportation and storage is easy: template can overlappingly be placed, transport, and the keeping space is few;
(5) can assemble in the inboard, reduce duration and cost, and can reversely remove;
(6) can adopt anticorrosion process (as ooze, method such as zinc-plated) to increase the service life;
(7) construction of various geology all can: the rock area both can be used, and soft stratum also can be constructed.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of template of bellows-shaped, its structure is shown in Fig. 1～3, ripple template 1 is an arc structure, and the middle part of longitudinal section is 2～4 undulatory arc-shaped structures, general preferred 3, protruding end face is set around the ripple template 1, connecting bolt hole 11 is set on this end face, and two connection end faces are plane structure up and down, and the width of plane structure and the degree of depth of arc-shaped structure are basic identical, according to the difference in upright hole of rectangle and the upright hole of circle, linearly structure in upper and lower end face or convex structure.
The mounting structure of the template of bellows-shaped as shown in Figure 4, after some ripple templates 1 are spliced into cylindrical-shaped structure, bolt is passed connecting bolt hole 11 connect ripple template 1 all around, utilize reinforcing ring 2 to fix then in the junction, reinforcing ring is provided with junction plate 3, and ripple template 1 is connected with reinforcing ring 2.Circumferencial direction then can according to about 1.5 meters length, manufacture arc section according to not the waiting of the diameter in upright hole, each adjacent surface connects with bolt, pitch of bolts can be set as about 200mm, and according to the difference of thickness of slab (from 2.7 millimeters to 7 millimeters), every weight does not wait to 60kg at 13kg.
Can take following steps when using the utility model:
The excavation at initial stage and assembling: excavate a vertical hole bigger slightly 200 millimeters, dark 0.5～1.5 meter, then fissure of displacement assembling tailored template 1 to 3 ring than intended diameter.
Adopt the top of 2 kinds of way set wave pattern plates:
(1), be combined into well word girder with i iron etc., a few ring wave mode templates that assembled with fixation with steel wire again, simultaneously, confirm the size in template levelness and upright hole after, periphery is filled out back compacting with soil.
(2), fix: confirm that the correct back of size fixes the periphery of template with setting concrete,, use chock, interior circle to use the way of cross steel support in periphery for preventing to set moving of template in the concrete process with concrete.
Sequence of construction: after the top has been fixed, down begin to excavate assembling, for preventing to cheat the wall collapse, can not full face excavation.As long as excavate the space that to adorn a slice template, and install and fix bolt temporarily.After treating that a ring installs, confirmed that cross dimensions is errorless, carried out formal bolt again and tighten, adopt staggered joint erection to improve bulk strength.
The installation of reinforcing ring: will be every certain spacing (according to the degree of depth and soil property) erector's font reinforcing ring according to design.
Slip casting: the grouting valve by 2 cun of reservations on the template, carry out suitable slurries (injecting with natural pressure).For the deep foundation construction, can after having been broken concrete as permanent lining, secondary lining, template carry out slip casing by pressure from default Grouting Pipe again.
Protective equipment: during the driving of upright hole, injure underground operators by a crashing object for preventing falling rocks or ground junk from the basket for holding earth, must be every 5～6 meters degree of depth settings.
Circular upright hole arrives well: when the circular diameter that arrives well is big, increase reinforcing ring, be provided with at interval will be with the difference of the degree of depth of well difference, by 0.5 meter～1 meter, 0～10 meter depth bounds is by 1～2 meter during general 10～20 meters degree of depth.Near the hole, stiffening girder is set strengthen.
The parameter comparison of the utility model and common planar pattern plate is as shown in table 1.
Two kinds of cross section property contrasts of table 1
As seen from the above table: the corrugated steel template of this worker method is compared under the situation of common plane steel form increase by 25% at Unit Weight, self rigidity improves greatly, flexural strength also can increase by 51%, through the finite element modelling analysis, under the pressure of equal 0.2MPa, the corrugated steel template is compared common plane steel form rigidity has increased by 78%, and intensity has increased by 44%.
The utility model equally also can be applied to the construction of horizontal tunnel, in the Mine Method construction at weak soil geology at present, generally adopts the arch i iron to support every a determining deviation (about 1 meter).Owing to can not in time carry out supporting with shaped steel plate, exist the possibility of landslide at circumferentially full section.The Tunnel Landslide accident examples also occurs repeatedly.If adopt the extraordinary template of the used wave mode of this law, circumference carries out uninterrupted supporting, and support is assisted a ruler in governing a country with reinforcing ring in the centre, then can thoroughly prevent the generation of landslide accident.
