Problems solved by technology

However, the pier of the cross-sea bridge should not only consider the collision prevention of ships and heavy objects, but also consider the impact and wear of the pier by waves and debris in the water. If the impact wears for a long time, it will affect the structure of the pier and reduce its bearing capacity.
The bridge pier guardrail that prevents the impact of waves and debris in the water on the pier has not been specifically disclosed at present.

Embodiment Construction

[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0009] Such as figure 1 The pier guardrail of the cross-sea bridge shown includes two symmetrical steel cables 1 facing the tide outside the pier, and eight struts 2 are connected between the two symmetrical steel cables 1, and the struts 2 can be Moso bamboo, or a PPR tube is socketed outside the moso bamboo, or a wooden stick. Two symmetrical steel cables 1 are provided with a protective net 3, and the two sides of the protective net 3 are provided with a floating rope 4. The floating rope 4 and 8 supports The rods 2 are fixedly connected, and each buoy 4 is provided with 8 colored floats 5, and each steel cable 1 is connected with 10 pile cables 6, and the pile cables 6 are connected with the fixed piles 7 on the seabed.

[0010] According to the size of the pier and the strength of the waves on the sea surface, 5, 10, 15, etc. of the abov...

Abstract

The invention discloses a bridge pier fence netting of a cross-sea bridge. The bridge pier fence netting comprises two symmetrical steel cables arranged outside a bridge pier facing tides, at least five supporting bars are connected between the two symmetrical steel cables, a protective net is arranged in the two symmetrical steel cables, floating ropes are arranged on the two sides of the protective net and are fixedly connected with the at least five supporting bars, each floating rope is provided with at least five colored floaters, each steel cable is connected with at least five pile cables, and the pile cables are connected with undersea fixing piles. Therefore, frontal sea waves, tidal ranges and sundries along with the tides can be blocked by the bridge pier fence netting, impactive abrasion of the sea waves and the sundries in water on bridge piers is reduced, and the bridge piers of the cross-sea bridge are protected.

Description

technical field [0001] The invention relates to a pier protection device of a sea-crossing bridge, in particular to a net fence for pier protection of a sea-crossing bridge. Background technique [0002] The pier operation is an important part of the bridge, and the safety of the pier is directly related to the efficient operation of the bridge. The protection of the pier has also become an important link in the maintenance of the bridge. Most of the currently disclosed pier protection devices focus on the design of preventing collisions such as ships and heavy objects. For example, the publication number is CN102296553A, and the invention patent named "Jianghe old bridge pier protection device" discloses a pier protection device, The pier protection device and the tie rod mechanism constitute the anti-collision, protection and protection devices; the pier protection device is to prevent frontal collision, and the pier protection device is to prevent side collision. However...
