But when building UHV transmission tower, most of old steel tower and newly-built new steel tower are on same path, it is necessary to It just can be carried out construction after former route grounded-line, steel tower are removed.Angle steel an iron rake with three to six teeth dismounting in China's still belongs to the primary stage, needs to pass through Worker removes, and large labor intensity, working efficiency are low, and risk is high.It, can not be by punching explosion, only in angle steel an iron rake with three to six teeth Energy dobie, a big chunk energy are dispersed into air, and demolition effect is poor.Since power transmission tower is located at mountain area, without abundance Electric power, scene not can be carried out welding, cannot large batch of shipped material moreover, traffic of mountain area is inconvenient.
Summary of the invention
Goal of the invention:In order to overcome the deficiencies in the prior art, the present invention provides a kind of utilization preformed particles medium The method of explosion power transmission tower, it is only necessary to whole device is fixed into tubular structure using angle steel and bolt, put in confined space It is equipped with preformed particles medium and pack, using the Incoercibility of preformed particles medium, greatly improves explosion extent of the destruction, It can guarantee demolition effect.
Technical solution:In order to solve the above technical problems, the method for the invention using preformed particles medium explosion power transmission tower, Include the following steps:
(1) according to the structure of power transmission tower, the first angle steel, the second angle steel, third angle steel and the fourth angle of suitable dimension are processed Fourth angle steel is welded on the both ends on the inside of the first angle steel by steel;
(2) it is punched in the first angle steel, the second angle steel, third angle steel and fourth angle steel suitable position, prepares preformed particles and be situated between Matter, pack, Nonel detonator, connecting tube;
(3) demolition set is transported at power transmission tower, the first angle steel is formed by the second angle steel and Bolted angle connection to be blasted Tubular structure installs third angle steel in the bottom of tubular structure, and third angle steel is connected by bolt and the first angle steel and fourth angle steel It connects, by the sealed bottom of tubular structure;
(4) connecting tube is put into tubular structure, pack is put into connecting tube, and pack passes through stemming in connecting tube Fixed, pack is drawn out to outside tubular structure by Nonel detonator, and preformed particles medium is filled outside connecting tube, until prefabricated Slightly below the first angle steel upper end opening height after the completion of granule medium natural subsidence;
(5) tubular structure is sealed by third angle steel at the top of tubular structure, third angle steel and the first angle steel and the 4th Angle steel is bolted;
(6) it protects, evacuate, warning, can detonate after the completion of preparation before detonating.
Preferably, being machined with waist type groove on the third angle steel.
Preferably, the pack is rock emulsion explosive in the step (2), it is easier to obtain compared with control explosive.
Preferably, in the step (4), the interval 10-20cm of adjacent pack in the connecting tube, same amount of fried Dose more makes full use of explosive acting ability.
Beneficial effect:Method using preformed particles medium explosion power transmission tower of the invention, it is only necessary to utilize angle steel and spiral shell Whole device is fixed into tubular structure by bolt, and preformed particles medium and pack are placed in confined space, utilizes preformed particles The Incoercibility of medium greatly improves explosion extent of the destruction, can guarantee demolition effect;And concrete block is compared, Preformed particles medium is more conducive to transport, the explosion of the more suitable power transmission tower for having inconvenient traffic.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the cross-sectional view of Fig. 1.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As depicted in figs. 1 and 2, the blasting method of the device of the invention using preformed particles medium explosion power transmission tower, packet Include following steps:
(1) as needed, the first angle steel 1, the second angle steel 3, third angle steel 4 and the fourth angle steel 5 of suitable dimension are processed, it will Fourth angle steel 5 is welded on the both ends of 1 inside of the first angle steel;
(2) it is punched in the first angle steel 1, the second angle steel 3, third angle steel 4 and 5 suitable position of fourth angle steel, prepares prefabricated Granule medium 2, pack 7, Nonel detonator, connecting tube;
(3) demolition set being transported at power transmission tower, the first angle steel 1 is connect by the second angle steel 3 with angle steel 6 to be blasted, Tubular structure is formed, third angle steel 4 is installed in the bottom of tubular structure, third angle steel 4 passes through bolt and the first angle steel 1 and the 4th Angle steel 5 connects, by the sealed bottom of tubular structure;
