Abstract
Description
Technical Field
[0001] This utility model relates to an offshore rock-laying engineering structure, and more particularly to an offshore rock-laying seawall stabilization engineering structure. Background Technology
[0002] Many of my country's developed regions are located along the coast. For the convenience of living and working, numerous port areas have been established along the coast to meet the daily needs of people. To improve the quality and safety of the living environment, seawalls need to be built between the port areas and the sea. Some existing seawall projects rely on outdated pine pile protective structures. Due to the rotten nature of pine piles, these projects have short lifespans, low quality, and are prone to leakage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an offshore rock-filled seawall safety engineering structure to address the shortcomings of existing technologies.
[0004] To achieve the above objectives, the present invention adopts the following measures:
[0005] An offshore rock-filled seawall safety engineering structure includes a rock-filled platform set above the outline of the rock-filled embankment. A concrete ground beam is laid at the same height as the rock-filled platform on the inland side of the platform. A concrete slope is inclined on the inland side of the concrete ground beam. A reinforced concrete fence is laid on the slope of the concrete slope. A reinforced concrete wave wall and a concrete retaining wall are set opposite each other on the inland side of the concrete slope. The reinforced concrete wave wall is set closer to the sea. A road surface is laid in the space between the reinforced concrete wave wall and the concrete retaining wall. A concrete seepage-proof wall is vertically set below the road surface. The cross-section of the concrete retaining wall is a right trapezoidal structure with the inclined surface facing the sea. The reinforced concrete wave wall is set at a height higher than the concrete retaining wall. The lowest point of the reinforced concrete wave wall is lower than the highest point of the reinforced concrete fence.
[0006] The concrete retaining wall is provided with a reinforced concrete base slab at the bottom. The reinforced concrete base slab extends into the lower part of the road surface on the seaward side. A first plain concrete pad layer is laid on the bottom of the reinforced concrete base slab. The inner seaward side of the reinforced concrete base slab extends out of the concrete retaining wall by a length.
[0007] The road surface consists of, from top to bottom, a slag fill layer, a cement-aggregate stabilized layer, and a concrete pavement.
[0008] The concrete anti-seepage wall is placed within the outline of the riprap toe protection at a depth of one meter.
[0009] An electronic fence is installed on the top of the reinforced concrete wave-breaking wall;
[0010] The top of the concrete retaining wall is equipped with a stainless steel railing.
[0011] The concrete ground beam is covered with a crushed stone cushion layer.

A concrete ground beam 3 is laid at the same height along the inland side of the riprap platform 2. A concrete slope 4 is inclined along the inland side of the concrete ground beam 3. A reinforced concrete fence 5 is laid on the slope surface of the concrete slope 4. A reinforced concrete wave wall 6 and a concrete retaining wall 7 are oppositely installed on the inland side of the concrete slope 4. The reinforced concrete wave wall 6 is positioned closer to the sea. A road surface is laid in the space between the reinforced concrete wave wall 6 and the concrete retaining wall 7. A concrete anti-seepage wall 11 is vertically installed below the road surface. The concrete retaining wall 7 has a right-angled trapezoidal cross-section, with its inclined surface facing the sea. The reinforced concrete wave wall 6 is positioned one height higher than the concrete retaining wall 7, and the lowest point of the reinforced concrete wave wall 6 is lower than the highest point of the reinforced concrete fence 5. The concrete anti-seepage wall 11 not only prevents seepage but also supports the road surface, preventing road settlement and collapse.
[0018] This offshore rock-filled seawall safety project involves the design of a rock-filled platform 2 and a concrete cutoff wall 11. The cross-section of the rock-filled platform 2 is typically a parallelogram structure. The surface of the rock-filled platform 2 is neatly arranged, with each surface rock weighing more than 60 kg. The thickness of the concrete cutoff wall 11 is not less than 600 mm. During construction, the rock-filled platform 2 will maintain a high tide level no lower than the historical average.
[0019] The concrete anti-seepage wall 11 effectively prevents leakage.
[0020] The lower part of the concrete retaining wall 7 is provided with a reinforced concrete base plate 12. The reinforced concrete base plate 12 extends into the lower part of the road surface on the seaward side. A first plain concrete cushion layer 13 is laid on the lower part of the reinforced concrete base plate 12. The inner seaward side of the reinforced concrete base plate 12 extends out of the concrete retaining wall 7 by a length.
[0021] The road surface consists of, from top to bottom, a slag filling layer 8, a cement-crushed stone stabilizing layer 9, and a concrete road surface 10.
[0022] The concrete anti-seepage wall 11 is placed within the outline 1 of the riprap toe protection at a depth of one degree.
[0023] An electronic fence 14 is installed on the top of the reinforced concrete wave wall 6. The electronic fence 14 is used to monitor the offshore environment.
[0024] The top of the concrete retaining wall 7 is equipped with a stainless steel railing 15, which improves the safety of pedestrians and vehicles traveling on the road.
[0025] The concrete ground beam 3 is provided with a crushed stone cushion layer 16 at its lower part.
