Problems solved by technology

[0002] When carrying out blasting construction in an area with relatively turbulent water flow, due to the fast water flow and the impact of turbulent water flow, the detonating tube and detonating cable are often broken and damaged, which affects the explosion transmission. In this case, it is easy to cause blind blasting of explosives. and invalid blasting operations, a series of safety problems will follow

Embodiment 1

[0042] An example of the water transport engineering network security construction method described in the present invention comprises the following steps:

[0043] (1) Construction design

[0044] According to the hydrological and geological conditions of the construction area and combined with the actual project, draw the construction design drawing and design the safe blasting network;

[0045] (2) Calculate the length of the protective rope

[0046] In order to prevent the detonating tube and detonating cable in the blasting network from being damaged by the impact of the torrent, the length of the protective rope 3 is designed to maintain safety under the condition of the torrent, so as to ensure that the blasting network is not damaged. The length of the protective rope is calculated according to the following formula:

[0047]

[0048] In the formula: L --- the length of the protective rope; H 1 --- The distance from the deck of the drilling rig to the water surfac...

Abstract

The invention discloses a water transportation engineering network safe construction method. The method comprises the following steps of (1) construction design; (2) calculating of the length of a protective rope; (3) measuring and positioning; (4) underwater drilling; (5) grain installing; (6) arranging of a security detonation network; and (7) checking of the security detonation network. By means of the method, the safety and reliability of the detonation network can be improved, and the phenomena of unexploded blasting, invalid blasting operation and the like caused by the fact that a detonating tube and a detonating cable are snapped and damaged due to rapid flow impact are avoided. The method is suitable for underwater drilling and blasting construction of a torrent area in inland port channel construction, water conservancy and hydropower construction and coastal port channel construction projects.

Description

technical field [0001] The invention relates to a construction method for an underwater safety detonation network in a water transportation construction project, in particular to a construction method for a water transportation engineering network safety. Background technique [0002] When carrying out blasting construction in an area with relatively turbulent water flow, due to the fast water flow and the impact of turbulent water flow, the detonating tube and detonating cable are often broken and damaged, which affects the explosion transmission. In this case, it is easy to cause blind blasting of explosives. And invalid blasting operations, there will be a series of safety problems. Contents of the invention [0003] The purpose of the present invention is to provide a safe construction method for the waterway engineering network for the waterway construction project. By extending the detonating tube in the blasting network through the protective tube to the outside of...
