A Peripheral Rockfall Prevention Enclosure Device for Caisson Construction

Abstract

The invention provides an outer rockfall protection enclosure for caisson construction, which includes a warning light bar and a waterproof support rod; The supporting wheels are rotatably connected to the bottom of the light guardrail; the LED lighting strip is installed on the light guardrail, and the LED lighting strip is connected to the external control circuit through the power line; there are four fences, and the four fences are respectively Installed on the top end faces of four lightweight guardrails; the inner side of the rockfall storage tank is inclined, and the rockfall storage tank is installed on the light guardrail; the warning light bar is long, and the warning light bar is installed on the light It is conducive to the movement of the device, so that the device can be installed at the wellhead of the caisson in a circular shape, and the wellhead can be surrounded and protected to prevent the loosened gravel at the wellhead from rolling down to the bottom of the caisson, resulting in Security risks.

Description

technical field [0001] The invention belongs to the technical field of caisson construction protection, and more specifically relates to a peripheral anti-rockfall enclosure device for caisson construction. Background technique [0002] The caisson is a shaft-shaped structure. It excavates the soil in the well, relies on its own gravity to overcome the friction of the well wall and sinks to the design elevation, and then seals the bottom with concrete and fills the well hole to make it a bridge pier or other structures. Foundation. It is generally used in the construction of foundation pits of large bridge piers, sewage pumping stations, large equipment foundations, civil air defense shelters, shield assembly wells, underground lanes and station hydraulic foundation construction enclosures. [0003] The inventors of the present invention have found that there are similar anti-rockfall enclosure devices for caissons, such as the Larsen steel sheet pile enclosure device for c...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a peripheral anti-rockfall enclosure device for caisson construction to solve the problem of poor protection for the wellhead of the caisson in existing similar devices, and the loose gravel at the wellhead due to construction is easy to fall If it reaches the bottom of the caisson, it will cause harm to the construction personnel at the bottom and affect the safety during construction; and the function is relatively single, and it cannot effectively cover the top of the caisson during the rainfall period. Rainwater is easy to accumulate inside the caisson, making construction more difficult and affecting construction progress issues
