Description
[technical field]
The invention belongs to blasting protection field, it is related to a kind of Tunnel Blasting protection bamboo raft reinforcement wall and preparation method thereof.
[background technique]
Constructing tunnel relies primarily on explosion at present, the issuable adverse effect of protected object near the area explosion Shi Duibao.
The vibration as caused by explosion individual flyings, air-shock wave, noise, underwater shock wave, flowing pressure, surges, dust, has
Evil gas etc..If blast area is located near visit scenic spot, 3 warning points need to be set, and 1# warning point is at 200 meters of blast area due west
The rear setting of machinery side by side outside prevents someone from entering work zone by sidewalk, and 2# warning point is 260 meters of the northeast Dong Ding
Pavement fork in the road is swum, prevents visitor from crossing enclosing and enters work zone；3# warning point, which is located at fire point southeastern direction, prevents ditch
Someone's drop-in.Winged corpse when explosion may injure building by a crashing object or treasure trees, and while explosion, have noise pollution with
And pernicious gas pollution；For this purpose, a large amount of human resources need to be expended.
Mostly use two kinds of protectiving schemes greatly in the prior art:
(1) cubic metre of earth and stone protection is at tunnel face, at 20 meters of face explosion rear place, banks up a large amount of slags of delaying, width should reach
To boundary is excavated, height is no less than 3m.With the slungshot for preventing Tunnel Blasting from generating.Program abundant raw materials are easy to get, but mechanical
Demand is big, though winged corpse diffusion length can be effectively reduced, noise is lower smaller, while the program is affected time-consuming, working efficiency
It is low.
(2) steel plate protectiving scheme.Before Portal Section blast working, splices one block of steel plate, used before explosion, it will with job platform
Steel plate is close to Tunnel muzzle arch and is close to Tunnel muzzle arch progress blasting protection.The program need to process baffle, fee of material in advance
It is higher, it can reuse, 1 loading machine is needed to be bulldozed platform；Though slungshot diffusion length can be effectively reduced, noise is reduced, needs weight
Multiple assembly steel plate, working efficiency are lower.
[summary of the invention]
It is an object of the invention to overcome the above-mentioned prior art, a kind of Tunnel Blasting protection bamboo raft reinforcement wall is provided
And preparation method thereof.
In order to achieve the above objectives, the present invention is achieved by the following scheme:
A kind of Tunnel Blasting protects bamboo raft reinforcement wall, including protective plate and is installed on the bracket of protective plate behind；Protective plate
Several reinforcement ribs including the panel and back side of panel that are bonded with tunnel face；Panel is woven by several using bamboo dough sheet
Bamboo panel constitute, the shape of several bamboo panels is identical as the shape of tunnel excavation section；The marginal dimension of entire panel exceeds
Tunnel contour line 50cm；Several reinforcement ribs are welded on bracket, form reticular structure in a crisscross manner.
A further improvement of the present invention lies in that:
One bamboo panel is made of six roots of sensation bamboo dough sheet, and six roots of sensation bamboo dough sheet is as booster bamboo dough sheet, then by single bamboo dough sheet
It successively crosses through to form a bamboo panel；The length of bamboo dough sheet is 3-4.5m, width 6-10cm, between adjacent bamboo dough sheet
Spacing is 5-10mm.
Between reinforcement rib is set to back side of panel in length and breadth, and at every spacing 50cm setting one.
Bracket is welded using the support tripod of steel pipe production, and with reinforcement rib；The diagonal brace length of support tripod
For 6m, erecting support length is 4.2m, and spacing 2m is together.
Diameter of steel tube is 42mm, spacing 2m.
There are the doors entered and left for explosion personnel for panel center bottom.
A kind of production method of bamboo raft reinforcement wall, comprising the following steps:
Step 1: bamboo dough sheet being woven into shape corresponding with tunnel excavation section, bamboo panel is made；
Step 2: overlapping in length and breadth add reinforcement rib on the back of the panel, then bamboo panel binding is completed into protection on bracket
The production of plate；
Step 3: reinforcement rib and bracket being welded, the production of entire bamboo raft folder muscle wall is completed.
Its further improvement is as follows:
The specific method is as follows for the braiding of bamboo dough sheet in step 1:
Setting six roots of sensation bamboo dough sheet successively crosses through to form a bamboo face as booster bamboo dough sheet, then by single bamboo dough sheet
Plate.
Compared with prior art, the invention has the following advantages:
Bamboo raft reinforcement wall of the present invention before Portal Section blast working, is close to Tunnel muzzle arch setting bamboo raft reinforcement and keeps off stone walling,
Prevent individual fly-rock throwing too far；The present invention needs to process baffle in advance, and fee of material is lower, can reuse；It can be effectively reduced
Slungshot diffusion length, preferably reduction noise；It after machine-shaping of the present invention, can repeatedly utilize, quick for installation, work efficiency is high.
According to " shotfiring safety regulation " (GB6722-2011), blasting flyrock safe distance is 70 meters, and the present invention can make quick-fried
Broken slungshot diffusion length is reduced to 30 meters；According to the requirement of locating geographical environment, vibrating noise is 90 decibels, and the present invention can make quick-fried
Noise is reduced to 60 decibels at area's 260m residential house.
