Abstract
The utility model discloses a kind of device of sound insulation and noise reduction closed shaft well head, including skeleton（1）, rubber big gun quilt（2）, acoustical cotton（3）, steel plate（4）, shackle（5）；Described skeleton（1）It is made up of shaped steel welding；Described rubber big gun quilt（2）It is fixed on skeleton（1）Towards the side of Shaft bank；Described acoustical cotton（3）It is arranged in skeleton（1）Inside, by skeleton（1）Filling is closely knit；Described steel plate（4）Thickness is less than 3mm, is fixed on skeleton（1）The dorsad side of Shaft bank；Described shackle（5）Quantity is even number, is welded on skeleton（1）On both sides of the edge, arrange in symmetry shape.This utility model is for sound insulation and noise reduction during subway vertical shaft blast working is with compared with strong adaptability.Before vertical shaft explosion, this device is covered on well head, prevents blasting flyrock from flying out well head, while realizing sound insulation and noise reduction.
Description
Technical field
This utility model belongs to Harmful effects from blasting control field, is related to a kind of dress of sound insulation and noise reduction closed shaft well head
Put.
Background technology
Before constructing metro tunnel, need from the position being pre-designed to be faced down excavating shaft by ground.Limited by execution conditions,
Construction of Silo typically adopts drilling and blasting method.Drill bursting construction can produce the ill-effects such as Property of Blasting Noise, blasting flyrock, to nearby residents
Impact, form potential safety hazard.Therefore, it is necessary to be controlled to the explosion net effect of Construction of Silo.Existing control skill
Art is the covering gun quilt on vertical shaft blasting face, although can solve the problems, such as blasting flyrock, but uncontrollable Property of Blasting Noise.
Therefore, the ill-effects such as a kind of produce when needing device badly to vertical shaft drill bursting construction blasting flyrock, Property of Blasting Noise are controlled.
The content of the invention
The purpose of this utility model is cannot to reduce asking for Property of Blasting Noise for existing Harmful effects from blasting control technology
A kind of topic, there is provided device of sound insulation and noise reduction closed shaft well head.
The purpose of this utility model can be realized by following technical proposal：
A kind of device of sound insulation and noise reduction closed shaft well head, it is characterised in that including skeleton, rubber big gun quilt, acoustical cotton, steel
Plate, shackle；Described skeleton is made up of shaped steel welding；Described rubber big gun is fixed on skeleton towards the side of Shaft bank；
Described acoustical cotton is arranged in skeletal internal, skeleton is filled closely knit；Described steel plate thickness is less than 3mm, is fixed on skeleton
The dorsad side of Shaft bank；Described shackle quantity is even number, is welded on skeleton both sides of the edge, is arranged in symmetry shape.
A kind of device of above-mentioned sound insulation and noise reduction closed shaft well head, it is characterised in that：Described frame configuration and needs
The Shaft bank of closing is similar to, and size is more than the Shaft bank for needing closing.
In a kind of device of above-mentioned sound insulation and noise reduction closed shaft well head, rubber big gun is iron wire with the fixed form of skeleton
Bind or screw are fixed.
In a kind of device of above-mentioned sound insulation and noise reduction closed shaft well head, the fixed form of steel plate and skeleton is fixed for screw
Or welding.
This utility model can effectively reduce the noise of blasting of incoming residential block, eliminate the harm of blasting flyrock.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, skeleton；2nd, rubber big gun quilt；3rd, acoustical cotton；4th, steel plate；5th, shackle.
Specific embodiment
Specific embodiment of the utility model is the following is, with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but this utility model is not limited to these embodiments.
A kind of device of sound insulation and noise reduction closed shaft well head, including skeleton 1, rubber big gun are by 2, acoustical cotton 3, steel plate 4, shackle
5.Described skeleton 1 is made up of shaped steel welding, and shape is similar with the Shaft bank for needing closing, and size is perpendicular more than needs closing
Well well head.Described rubber big gun is fixed on skeleton 1 towards the side of Shaft bank by 2, and fixed form is adopted and is screwed.It is described
Acoustical cotton 3 be arranged in inside skeleton 1, skeleton 1 is filled closely knit.Described 4 thickness 3mm of steel plate, is fixed on skeleton 1 and dorsad erects
The side of well well head, fixed form are adopted and are screwed.Described 5 quantity of shackle is 2, is symmetrically welded at 1 liang of side of skeleton
On edge.
Before vertical shaft explosion, shackle 5 is caught on the grabhook of crane or straddle truck, by the appliance cover on well head；Explosion
After the completion of, shackle 5 is caught on the grabhook of crane or straddle truck, the device is hung into well head.
