Semi-permeable groyne and molding method thereof

Abstract

The invention provides a semi-permeable groyne. The semi-permeable groyne is molded underground, and comprises a groyne body, an inverted filter layer, a protection surface structure and a wave wall, wherein the groyne body is a main body of the groyne; the inverted filter layer is laid on the groyne body; the protection surface structure is laid above the inverted filter layer to form a wave resisting structure; and the wave wall is mounted and laid at the top of the groyne body. Multiple sand bags are filled in the groyne body; gravels are filled in the sand bags; and the sand bags are constructed on water and built on the edge of the groyne body to form an underwater cofferdam so as to prevent the loss of backfill materials and reinforce the side edges of the backfill groyne body. The sand bags are covered with soil engineering pipe belts; the soil engineering pipe belts are built above the sand bags to form a land cofferdam; the tubular sand bags and the soil engineering pipe belts are respectively built on the edges of the groyne body to protect the backfill materials in the groyne center to prevent or reduce the permeable loss, so that the edges of the groyne body are reinforced, the antiskid stability of the groyne body is improved, the effect of reinforcing ribs is achieved, and the whole stability of the groyne is promoted; and the groyne center adopts the backfill materials to reduce such building materials as groyne center stones, so that the engineering cost is saved. The invention further provides a method for molding the semi-permeable groyne.

Description

technical field [0001] The invention relates to the field of hydraulic engineering such as breakwaters and revetments, in particular to a semi-permeable breakwater. Background technique [0002] Breakwaters are buildings built to block the impact of waves, protect the harbor basin, maintain a stable water surface, and protect the port from bad weather so that ships can berth and operate safely. The traditional structural forms can be mainly divided into vertical and slope Mode. [0003] Slope embankment is a widely used structural form of hydraulic breakwater. Its main feature is that the core of the embankment is made of rocks, and the requirements for the bearing capacity of the foundation are low, so it is suitable for sea areas with weak foundations. The waves are broken on the ground, the reflection in front of the embankment is small, the overall stability is high, and it is easy to maintain. Because of its simple structure, convenient construction and no need for l...

AI Technical Summary

Problems solved by technology

The square vertical embankment is durable, easy to construct, and can withstand relatively large waves. However, its own weight is large, the foundation stress is large, the amount of concrete is large, the workload of underwater installation and diving is large, the construction progress is slow, and the overall stability of the embankment is poor.

The overall stability of the caisson-type vertical dike is good, the installation workload on the water is small, and the construction progress is fast. Backfilling the gravel in the box can reduce the cost, but the water transportation of the caisson requires a channel with sufficient water depth. However, if it is damaged, the requirements for the bearing capacity of the foundation are high, and the waves on the top of the embankment will be larger.

The large-diameter cylindrical vertical embankment has a simple structure and low material consumption, and can be used on soft soil foundations, but its structure and mechanism are complex, and its use is subject to certain restrictions

[0005] Marine large-scale concrete buildings have certain environmental impacts. Over time, ions in concrete dialysis into seawater will have a certain impact on the marine environment. In areas with high environmental protection requirements, deep-water large-scale concrete structure breakwaters have environmental hazards.

[0006] At present, marine buildings are gradually becoming deeper and larger, site conditions are becoming more and more complex, and construction difficulty is also increasing. Traditional structural types have many restrictions on the amount of stone used in deep water breakwaters, foundation applicability, and structural environmental protection. Can no longer meet engineering requirements
