Description

Protective structure of pier

Technical Field

The utility model relates to the technical field of bridge construction, in particular to a protective structure of a pier.

Background

Local scouring exists near a cross-sea or cross-river bridge, and is an important factor causing bridge damage. Local flushing is usually due to three reasons: (1) the pier water blocking causes the surrounding flow velocity to increase, which means that the area of the cross section of water flow is reduced when the water flow meets an obstacle, the local flow velocity is increased, and the sediment on the bed surface is washed to form a washing pit; (2) the lower water flow undercuts the bed surface, mainly means that the lower water flow is formed after the forward water flow impacts the bridge pier, and a strong undercutting effect is generated on the bed surface; (3) horseshoe vortex scouring mainly refers to horseshoe vortices formed when water flow bypasses barriers and partial silt around the piers is swept away.

Generally, the local scour protection measures of the bridge pier are mainly divided into two types: (1) the active protection reduces the scouring energy of water flow to the pier, namely, reduces the downwash and the horseshoe vortex in the water flow scouring process, and measures such as enlarging the base plane of the pier or arranging a protection foot are generally adopted to reduce the scouring energy of the water flow. (2) Passive protection is adopted to improve the anti-scouring capability of a bottom bed near a pier, and stones are thrown or queen words are twisted around the pier foundation usually to try to improve the anti-scouring capability of the pier.

In the related art, a protective layer is generally constructed around a pier to reduce local scouring of the pier caused by water flow, the scouring of the pier is converted into scouring of the protective layer because the protective layer is generally composed of stones and concrete, and the connection between the stones and the concrete in the protective layer is easily broken due to erosion of the protective layer caused by corrosion bubbles in water for a long time.

Therefore, a protective layer with a long life and good protection is required.

Step S1: foreign materials outside the pier 1 are cleaned to expose the foundation bed of the pier 1, and the hollowed part in the foundation bed is confirmed.

The bottom of the pier 1 is submerged in a river throughout the year, and when water flows through the pier 1, soil and stones flowing through the pier 1 are easily retained due to the unsmooth surface of the pier 1, and accumulate near the pier 1, and some aquatic plants and algae grow. Before the maintenance of the pier 1, the sundries need to be cleaned, so that the foundation bed at the bottom of the pier 1 is exposed, a constructor can observe and detect the hollowed part at the bottom of the pier 1 conveniently, and a maintenance scheme is implemented for the hollowed part.

Step S2: underwater concrete is poured to fill the hollowed part, and crushed stone blocks 4 are filled to level the foundation bed.

Because the bottom of the pier 1 is usually a deep water area, the underwater concrete is poured by adopting a conduit method, when the underwater concrete is poured, the conduit is filled with the concrete, the pipe opening of the conduit is embedded in the concrete, the free surface layer concrete is contacted with water, the corresponding conduit is removed along with the rising of the pouring height, and the concrete contacted with the water is removed after the pouring is finished.

The particle size of the filler in the filler layer is increased from bottom to top in sequence, and the flow velocity of the water flow on the surface of the river is the highest, and the flow velocity of the water flow is gradually reduced along with the increase of the depth of the river. Aiming at the upper layer water flow, the water flow still has larger flow velocity after passing through the water permeable block 2, the water flow is directly blocked by arranging the filler with larger particle size, and the particle size range of the filler at the uppermost layer is 450-550 mm, so that the flow velocity is reduced; aiming at the lower layer water flow, because the flow velocity is slow, the impact force on the packing layer after passing through the permeable layer is also small, and the particle size range of the lowest layer packing is 250-350 mm by setting the packing with small particle size, so that the water flow is further divided to reduce the impact force. The packing layer that sets up the particle diameter difference avoids directly washing away pier 1 to the rivers of different velocity of flow, the impact force that slows down rivers that can be better, and the clearance between packing and the packing has formed a plurality of anomalous rivers passageways, makes the great rivers branch of a stock impact force be the less rivers of a plurality of stocks impact force, reduces the impact force to pier 1.
