Description

River channel interception device for bridge blasting

Technical Field

The utility model relates to the technical field of blasting safety equipment, in particular to a river channel interception device for bridge blasting.

Background

The broken bridge needs to be dismantled and rebuilt, and a blasting technology is generally adopted to dismantle the broken bridge, so that flying stones, shock waves, underwater shock waves and the like generated in the blasting implementation process can influence the safety of the surrounding environment of the bridge. In order to protect the environmental safety around the bridge, before blasting, firstly, covering and protecting the blasting position of the bridge by adopting a rubber net and a bamboo skin, and adopting sand bags for pressurizing and protecting the rubber net or the bamboo skin, so that interception can be carried out at the initial position of flying and shooting of flying stones, the initial speed of flying and shooting of the flying stones is reduced, and the scattering range and impact damage of the flying stones are reduced; then lay the sand bag in the vertical below of collapsing of bridge, excavate the shock attenuation ditch in bridge both sides simultaneously, through the combined action of sand bag and shock attenuation ditch, can effectively reduce blast wave and the vibrations harm of blasting construction. After the bridge surrounding environment is protected by adopting the measures, blasting construction is started, but after blasting, a large amount of construction waste and floaters are generated in the river channel, the construction waste and floaters can flow to the downstream river channel along with water flow, if the construction waste and the floaters are not timely treated, a large amount of influence is caused to the river water environment, moreover, the waste flows and is recovered to be difficult along with water flow, two interception fences are arranged at the 50m position and the 60m position of the downstream river channel, the length of each fence is consistent with the width of the water surface of the river channel, the fence foundation is arranged on the river bank, the foundation is a concrete block foundation with the width of more than 1m, steel pipe bent frames are adopted between the foundations, water fences are formed by connecting with wire nets, the construction waste falling into the river channel after blasting and the floaters are effectively intercepted, the construction waste falls into the river channel in a large amount, the water level of the river channel can not rise along with the rising water level, when the water level is higher than the wire nets, the wire nets can only intercept the construction waste at the bottom of the water, but the water is floated on the water surface of the water, the water garbage cannot flow along with the water flow to pollute the river channel, and the water is difficult to collect.

Disclosure of Invention

The utility model aims to provide a river channel interception device for bridge blasting, which solves the problem that the existing interception device cannot intercept garbage floating on the water surface because a wire netting cannot rise along with the rising of the water level.

In order to solve the problems, the technical scheme is as follows:

the utility model provides a river course intercepting device for bridge blasting, includes the steel pipe support and fixes the wire netting on the steel pipe support, the fish wire net is worn to steel pipe support top lead wire, and fish wire net top fixedly connected with is with the cursory of river face equiwidth.

The basic principle of the technical scheme is as follows: the steel pipe frame and the wire netting are arranged in a river channel, the wire netting intercepts construction waste sunk in river water, and along with the rising of the water level, a buoy with the same width as the river surface can always float on the water surface and pull the fish wire net to intercept the waste floating on the water surface.

The beneficial effects of the technical scheme are that: compared with the prior art that the wire netting is used for intercepting construction waste and floating waste or only the floating waste is adopted for intercepting the floating waste, the wire netting is adopted for intercepting the construction waste, the fish wire net is pulled along with the rising of the water level for intercepting the waste floating on the water surface, and the situation that the floating waste cannot be intercepted and flows to the downstream to cause more serious river pollution when the water level is prevented from passing through the wire netting is avoided.

Furthermore, the steel pipe frame is formed by arranging and fixedly connecting a plurality of transverse and vertical steel pipes in a crossed mode. The steel pipe frame formed by the cross arrangement and the fixed connection of the transverse steel pipes and the vertical steel pipes is used as a fixing rib of the wire netting, so that the wire netting is prevented from being broken due to the impact of water.

Further, the length of the transverse steel pipe is consistent with the width of the river surface, and the joint of the transverse steel pipe and the vertical steel pipe is fixed by adopting a fastener. The length of the transverse steel pipe is consistent with the width of the river surface, so that the steel pipe frame can fully enclose and block the river in the width direction, and the steel pipe frame connected by the fastener is convenient to detach after the steel pipe frame is used.

Further, the wire netting is covered with the whole steel pipe frame. The wire netting can intercept all the construction waste sunk in river water.

Further, concrete bases are fixed on two sides of the bottom end of the steel pipe rack, and the concrete bases are fixed on two sides of the river. The steel pipe frame is fixedly arranged in the river through the concrete base, so that the wire netting is arranged in the river.

Further, the periphery of the concrete base is obliquely provided with a reinforcing base. The reinforcing base further reinforces the stability of the concrete base.
