Description
Technical field
The present invention relates to a kind of demolition sets, and in particular to a kind of based on the axial underwater Cutting Seam Cartridge Blasting dress not coupled
It sets and its construction method.
Background technique
With further implementing for national basis Facilities Construction, the construction of port and pier, cruiseway, crossing bridge engineering
It quickly grows, geological conditions is that main port and waterway engineering usually uses drill bursting construction with rock, and Blasting Excavation has construction
At low cost, a rate of advance is fastly and technology reaches its maturity, and is widely used.However, underwater demolition and land-based area explosion are because of propagation of explosion medium
Difference causes its blast mechanism and construction technical requirement dramatically different, and especially bridge spanning the river pier footing underwater demolition excavates or navigates
Road basin fluting engineering, it is more demanding to the protection of basement rock integrality, and take conventional subsea Deep Hole Blasting destructible
The integrality of basement rock, it is uneven to often result in excavation face, improves subsequent construction to a certain extent, also increase later period dimension
Shield expense.The laying of continuous charging in conventional subsea blast hole, causes blasthole explosive specific charge big, and it is excessively high to bombard first pressing, hole wall rock
Stone transition is broken, and concussion of blasting is larger to the destruction of port area structure is closed on, to land and water ecological environment, aquatic organism and fishery cultivating
Etc. causing to seriously endanger.
Currently, explosion energy preferentially goes out to discharge from joint-cutting since underwater Cutting Seam Cartridge Blasting is limited by joint-cutting shell,
Blasthole radial direction pull crack is formed, energy directional aggregation reaches control rock mass cracking direction, therefore need to retain rock mass into that can reduce
Damage, be widely used in needing to protect the pier footing of basement rock, in the fluting engineering of navigation channel.And axial Uncoincided charge has
The consumption for reducing explosive, explosive, substantially reduces production cost, also reaches better demolition effect, therefore answered extensively
For in the engineerings such as presplit blasting and photoface exploision.But there are no do not couple underwater Cutting Seam Cartridge Blasting with axial so far
The combined demolition set of powder charge.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of underwater Cutting Seam Cartridge Blasting not coupled based on axial direction
Spaced loading capsule pipe is arranged in device, this demolition set in joint-cutting pipe, sufficiently combines segment algorithm with axial and does not couple explosion
The advantages of, using segment algorithm directional cumulation breaking controlled blasting technical advantage, is formed and the integrality of excavation foundation basement rock is protected
Shield reduces blasthole explosive specific charge, prevents that blasthole is excessively fried, reduces the injury to reservation rock mass, while controlling blasting impact to closing on
The hazard of vibration of structure and surrounding enviroment, and damper effect is obvious, overall economic efficiency is prominent；In addition, interval dress
Anther sac tube structure is simple, can standardize batch production, and pack manufacturing process can be completed job platform on the water, be greatly simplified
Underwater operation process, practicability are good.
In order to achieve the above object, the technical solution that the present invention takes:
Based on the axial underwater Cutting Seam Cartridge Blasting device not coupled, including joint-cutting pipe and primacord, the joint-cutting pipe
Top is equipped with tube top lid, bottom end is equipped with tube bottom lid, and the tube top lid and tube bottom Gai Junyu joint-cutting pipe are detachably cooperatively connected, described
Tube top covers the preformed hole offered for being laid with primacord, is symmetrically arranged with two along its axial direction on the tube wall of the joint-cutting pipe
Cutting seam, the joint-cutting pipe is interior to be equipped with a spaced loading capsule pipe, the cylindrical soft pipe of the spaced loading capsule pipe and tube wall
With a thickness of 1~4mm, the top of the spaced loading capsule pipe is connect by capsule tube top envelope with joint-cutting pipe, the spaced loading capsule pipe
Bottom end connect with joint-cutting pipe by capsule tube chassis, the inlay card that one is used to consolidate primacord is opened up in the capsule tube chassis and is consolidated
Hole, the spaced loading capsule pipe includes capsule tube wall and several in capsule tube wall seal independently of each other between separate space, it is described
Between separate space from the bottom up successively interval be set as explosive column, dielectric posts, the spacing distance between the explosive column and dielectric posts according to
Axial decoupling coefficient design, and separate space tamping between top, and be set as being equipped in the cavity wall of separate space between dielectric posts
One check valve, the dielectric posts are water column or air column, the primacord inlay card enter inlay card securement apertures it is fixed after, further along interval
Dress anther sac tube is laid with, finally extends out from the preformed hole of tube top lid.
As optimal technical scheme, in order to reduce demolition set under water explosion when buoyancy, be conducive to improve and cut under water
The demolition effect of pack is stitched, the dielectric posts are set as water column.
As optimal technical scheme, in order to avoid joint-cutting pipe is cut into two halves, while the width of cutting seam can control,
Be conducive to improve the efficiency that explosion is laid with work, the end of two cutting seams is 4~8cm at a distance from the end of joint-cutting pipe.
The present invention also provides the construction methods based on the axial underwater Cutting Seam Cartridge Blasting device not coupled, including following step
It is rapid:
1) drilling machine model, is selected according to demolition site, and the diameter of joint-cutting pipe is selected according to the drill bit of drilling machine, joint-cutting pipe can
