Description
Technical field
It the utility model is related to technical field of construction equipment, more particularly to a kind of vertical shaft Tunnel Blasting construction protection device.
Background technology
With the continuous development of urban rail transit in China, the construction in tunnel enters a peak period, High-Density Urban Area
Environment influence is the hot issue of underground engineering circle research in recent years caused by constructing tunnel, and earth's surface buildings or structures are intensive, work
Journey built environment is complicated, and owner's troxerutine tabtets are high.In High-Density Urban Area, blast working inevitably causes resident living
Influence, cause more serious social influence.
Since excavation of foundation pit is adjacent to residential house, security incident and the phenomenon that disturbs residents, such as noise of blasting, slungshot are easily produced.It is quick-fried
The harm of broken slungshot is mainly reflected in casualties, building damage, machinery equipment breakage etc., and casualties is explosion
The maximum harm of slungshot.Statistics shows, China due to casualties, building damage accident caused by blasting flyrock
Account for the 15%~20% of whole demolition accident.
Stake well bursting work is carried out in complex condition, it is necessary to the thought of " safety first " is established securely, it is scientifically real
Apply elimination or the effective technology measure of controlled blasting public hazards.Therefore, it is necessary to the occurrence situation such as stringent controlled blasting noise, slungshot,
Definitely ensure being perfectly safe for residential house around and personnel.
Utility model content
In order to overcome the problems referred above, the utility model provides a kind of vertical shaft Tunnel Blasting construction protection device, passes through installation
Can sound insulation and noise reduction, protect the protective device of slungshot, reduce harm of the blast working to residential house around and personnel.
The technical solution adopted in the utility model is：
Vertical shaft Tunnel Blasting construction protection device, including can assembled protective cover, can assembled protective cover include being used to make bone
The I-steel of frame, steel plate is fixedly connected with the I-steel, and I-steel forms half opening rectangular frame, the steel plate with steel plate
Top is provided with the hoisting ring being arranged side by side.
Further, the protective cover further includes rubber rete cutaneum, and the rubber rete cutaneum edge is provided with for passing around
The cord hole of steel wire rope.
Further, the purlin and bolt for fixing rubber rete cutaneum are provided with the steel plate so that the rubber skin
Net is detachable.
Further, reserved ventilating opening is provided with the protective cover.
The beneficial effects of the utility model are：
The vertical shaft Tunnel Blasting protective device structure of the utility model is simple, makes skeleton using I-steel, is fixedly connected
Steel plate forms half opening rectangular frame, and sets hoisting ring, and easy to lifting operation, dismounting is simple and convenient, and when explosion can sound insulation drop
Make an uproar, protect slungshot, securely and reliably, effectively solve the problems, such as that noise of blasting, slungshot endanger surrounding residential house and personnel.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment
In the description of the utility model, term " transverse direction ", " longitudinal direction ", " on ", " under ", "front", "rear", "left", "right",
The orientation or position relationship of the instruction such as " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on orientation shown in the drawings or
Position relationship, is for only for ease of description the utility model and simplifies description, is not instruction or implies signified device or member
Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
As shown in Figure 1 to Figure 3, one of embodiment provided by the utility model, wherein it is desired to which the protective device of installation includes
Can assembled protective cover, protective cover length is according to vertical shaft size design, between shaft width comes of age beam span.
Can assembled protective cover include I-steel 1, the I-steel 1 preferably takes 16~work of work 20, is made using two I-steel 1
Skeleton, steel plate 2 is fixedly welded with the I-steel 1, and I-steel 1 forms half opening rectangular frame, the steel plate 1 with steel plate 2
Top is welded with the hoisting ring 3 being arranged side by side, 2 hoisting rings 3 of often row's welding, for the company between lifting operation and protective cover
Connect.
The protective cover further includes rubber rete cutaneum, is worked out using the overlapping intersection of waste and old tire, rubber rete cutaneum surrounding
Edge is provided with the cord hole for passing around steel wire rope.The purlin 7 and bolt 8 of rubber rete cutaneum are fixed by being used for of being set on steel plate 1,
So that the rubber rete cutaneum is detachable.
If the protective cover at edge mutually conflicts with blanking hole site, preformed hole position is needed, the protective cover passes through one Pin of the rightmost side
Rectangular frame welding ventilating opening steel plate 4 sets reserved ventilating opening 5, in the case where not influencing to slag tap, edge protection cover can be consolidated
It is scheduled in Guan Liang.
The construction method of vertical shaft Tunnel Blasting construction protection device, comprises the following steps：
The first step：In face jewel hole powder charge, preparation before explosion is carried out；
Second step：By mechanical hoisting operation, per the lifting of Pin protective covers, in place, horizontal orientation arranges in ring grid beam；
3rd step：Between the protective cover arranged, reinforcing bar 6 is inserted into by hoisting ring 3 and is fixed, with increase protection dress
The stability and security put；
4th step：Vertical shaft Tunnel Blasting operation, and dedusting is divulged information；
5th step：The reinforcing bar 6 on protective device is pulled out, hangs out protective device, operation of slagging tap.
The preferred embodiment of the above, simply the utility model, the utility model are not limited to above-mentioned implementation
Mode, as long as it reaches the technique effect of the utility model with identical means, should all belong to the scope of protection of the utility model.
