[0002] The revetment structure of a waterway lock refers to the structure used to support and protect the land around the waterway lock, including retaining walls, revetments, docks and other buildings. Its function is to prevent water flow from eroding the shore land and ensure the safe passage of ships through the lock. The revetment structure design of a waterway lock needs to consider factors such as water flow and ship operation. It has a certain resistance to water flow impact and bearing capacity to ensure that the structure is stable and reliable. However, the revetment structure of some waterway locks did not take the impact of water flow impact into consideration during design, resulting in insufficient structural impact resistance and being easily eroded and damaged by water flow. At the same time, due to the long-term impact of water flow impact and ship collision, it is prone to aging and damage, resulting in a decrease in structural strength, increasing the frequency of regular inspections and maintenance, and increasing operating costs.

[0040] See also Figure 6 The present invention also provides a cooperative construction method for a waterway lock chamber, the construction method is applied to the revetment structure of the waterway lock, and comprises the following steps:

[0041] Step S1: installing the overhead gantry crane 71 on one side of the overflow dike 20 adjacent to the transition confluence surface 21, and installing the underframe gantry crane 72 on the top of the base surface layer 13;

[0042] Step S2: a plurality of column installation grooves are provided at intervals along the length direction on the top of the base surface layer 13, and a plurality of columns 31 are hoisted and installed in the plurality of column installation grooves respectively through the bottom frame door machine 72;

[0043] Step S3: The plurality of protective lock chambers 32 are hoisted and installed on the top of the base surface layer 13 through the overhead gantry crane 71 and the bottom frame gantry crane 72 respectively, and the plurality of base columns 31 and the plurality of protective lock chambers 32 are staggeredly connected.

[0044] For example, in one embodiment: the surface of the channel bank slope and the riverbed are excavated from top to bottom by layered blasting. When the excavation is 1.5m away from the designed channel bank slope and bedrock surface, small cannon blasting should be used for excavation, and at least 0.30m thickness should be retained, and then manual prying should be used to excavate to the designed channel bank slope and bedrock surface. During layered blasting and manual prying, it should be noted that all strongly weathered rocks on the channel bank slope and bedrock surface must be excavated and loose and cracked rocks must be pried off, so that the revetment foundation 10 and the overflow dike 20 are placed on fresh weakly weathered bedrock with good integrity. At the same time, the contour lines of the channel bank slope and bedrock surface should be as smooth as possible to avoid sudden changes with excessive height differences to avoid stress concentration and cracks. The height difference of protruding isolated rocks should not be too large, and the height difference should be controlled within 50cm, and sharp rocks should be removed.

[0045] The base shell layer 11 and the overflow dike 20 are both cast with silicate cement, and the casting height is 60 cm. During the casting process, observation must be strengthened to prevent the bedrock from being disturbed.

[0046] The base layer 12 is formed by concrete fine aggregate masonry blocks. Before paving, the base shell layer 11 should be ensured to have a certain strength, and the void ratio between the concrete fine aggregate masonry blocks should be less than 3%, and the dry bulk density should be greater than 23kN / m. The concrete fine aggregate masonry blocks should be hard, complete, and have sharp corners removed, and should be rinsed clean and kept moist.

[0047] For example, in one embodiment: a communicating drainage groove is recessed at the inner bottom of the transverse sliding cavity 412 .

[0048] For example, in one embodiment: when water flows toward the revetment foundation 10, the slope protection bricks are laid on the slope surface outside the base surface layer 13 to prevent the water flow from directly eroding the slope surface, and the slope protection bricks help to disperse and guide the water flow, reducing the impact force on the foundation structure, and the concrete anti-seepage panel used in the base surface layer 13 can effectively prevent the water flow from penetrating into the foundation structure, preventing the water flow from eroding or damaging the structure, and the base belly layer 12 has high compressive strength and stability, and its porosity is less than 3%, which can effectively reduce the penetration of the water flow into the structure and increase the overall stability. The gaps between the masonry stones are well filled, which further enhances the ability to resist water flow impact. Then, through the above-mentioned design and construction measures, the ability of the structure to resist long-term water flow impact can be effectively improved, ensuring the long-term stability and safety of the project.

[0049] For example, in one embodiment: when the water level rises, the water flow impacts the raised protective dam 30, or a ship collision occurs, causing the raised protective dam 30 to be severely impacted, since the outer side of the chamber body 40 is an elastic buffer portion 44, the top of the elastic buffer portion 44 will be slightly deformed inward, thereby pushing the upper flap shaft 61 to move downward along the vertical slide groove 444, so that the self-controlled flap 62 follows the movement, and then squeezes the elastic spiral roll 521, so that the elastic spiral roll 521 is compressed and deformed inward to absorb the impact kinetic energy. At the same time, the lower decompression seat 51 slides inward along the transverse sliding cavity 412, and multiple recovery decompression springs 513 are used to further disperse the impact kinetic energy to prevent the long-term impact of the water flow from causing the structural strength of the raised protective dam 30 to decrease.

[0050] For example, in one embodiment: when the water level is further raised to a height higher than the elastic buffer portion 44, the water flow will enter the hollow cavity 41, and under the guidance of the first focusing surface 431, the third focusing surface 435 and the second focusing surface 441, it will flow into between the self-control flap 62 and the downward pressure sealing plate 65, and as the water flow continues to enter, the gravity of the accumulated water and the gravity of the downward pressure sealing plate 65 will be greater than the elastic force of the multiple restoring decompression springs 513 and the elastic spiral roll 521, so that the self-control flap 62 moves further inward and downward, so that the downward pressure sealing plate 65 will also slide downward along the vertical installation slide groove under the action of gravity, so that the multiple connecting holes 653 will be connected with the connecting groove 433, so that the subsequent water flow will enter the connecting cavity 432 along the connecting groove 433, and then be discharged from the multiple outflow holes 434, so as to achieve hydraulic self-control and overflow.

[0051] Installation process: the base shell layer 11 is set on the channel bank slope, the base belly layer 12 is set on the base shell layer 11, the base surface layer 13 is set on the base belly layer 12, the bottom of the overflow dike 20 is installed on the bedrock surface of the channel, one end of the overflow dike 20 is connected to the outer bottom of the base surface layer 13, and its connection portion forms a smooth transition confluence surface 21, the other end of the overflow dike 20 is inclined upward and convexly provided with a discharge protrusion 22, a plurality of base columns 31 and a plurality of protective lock chambers 32 are respectively installed at intervals along the length direction on the top of the base surface layer 13, and the plurality of base columns 31 and the plurality of protective lock chambers 32 are staggered and connected, the bottom of the base 42 is installed on the top of the base surface layer 13, the bottom surface of the fixing portion 43 is installed on the inner side of the top surface of the base 42, and the elastic buffer portion 44 is installed on the base 42 top surface outer side, the lower pressure reducing seat 51 is slidably installed in the horizontal sliding cavity 412, the pressure reducing shaft 52 is installed at the outer bottom of the hollow cavity 41, and the two ends of the upper flap shaft 61 are respectively slidably installed in the two vertical slide grooves 444, the top of the automatic flap 62 is rotatably installed in the upper flap shaft 61, the lower flap shaft 63 is installed in the lower pressure reducing seat 51, the bottom end of the automatic flap 62 is rotatably installed in the lower flap shaft 63, and the bottom surface of the automatic flap 62 is abutted against the outer wall of the elastic spiral roll 521, the outer end of the rotating plate 64 is rotatably installed on the outer top of the rotating preset groove 442, the inner side of the bottom surface of the rotating plate 64 is recessed with a supporting plate 66, the bottom surface of the supporting plate 66 abuts against the top surface of the automatic flap 62, and the inner side of the lower pressure sealing plate 65 is slidably installed in the vertical installation slide groove.

At the same time, it can dynamically adjust functions to effectively control the overflow volume, ensuring that when the water level continues to rise, excessive water flow can be released in a timely manner to avoid potential dangers such as dam breach or structural failure due to excessive water accumulation, reducing the need for manual intervention, and realizing the ability to automatically respond to changes and impacts in water surface height, thereby reducing the cost and difficulty of maintenance and management.
