Detailed Description
The invention is described in detail below with reference to the drawings and the detailed description.
As shown in fig. 1, 3 and 4, the present embodiment provides a sealing system between a bottoming member and an underwater concrete foundation bed, which includes a member main body, a concrete conduit 2, a grouting pipe (omitted in the figures) and a pad 3, wherein the member main body includes a bottom plate 11, an outer side plate 12 and an inner side plate 13, the outer side plate 12 is fixedly connected to a terminal of a periphery of the bottom plate 11 to form a large cavity with an upper opening, the inner side plate 12 is located in a middle position of the bottom plate 11 and is fixedly connected to the bottom plate 11 and the outer side plate 12 to divide the large cavity into a plurality of small cavities 14, a grouting hole 111 is formed in the bottom plate 11 of each small cavity 14, the concrete conduit 2 is fixedly connected to the grouting hole 111, the grouting pipe is detachably connected to the concrete conduit 2, and the pad 3 is detachably clamped to the bottom plate 11. The bottom plate 11 may be a regular surface such as a plane, a curved surface, or other irregular surface, and the bottom member may be made of concrete, steel, or other materials satisfying mechanical properties of the foundation bed. The bottom-equipped member in the embodiment has a stable and reliable structure, is suitable for construction of the underwater concrete foundation bed 5, and injects concrete into the foundation trench 41 through the grouting pipe, the concrete guide pipe 2 and the grouting hole 111, so that the step of floating the foundation bed by an underwater constructor is reduced, the construction process is simpler, the joint degree of the top surface of the underwater concrete foundation bed 5 and the bottom-equipped member is higher, and the stability of the whole structure is improved.
As shown in fig. 2, in the construction of the underwater concrete foundation bed in the prior art, a foundation trench 41 is firstly formed on an underwater bottom surface 4, then the foundation trench 41 is poured by directly pouring underwater concrete, and the concrete is trowelled by an underwater constructor. After the concrete foundation 5 has reached the strength requirement, the prefabricated elements are placed directly on top of the concrete foundation 5. The underwater operation environment in the construction process is complex, the difficulty is high, and the requirement on divers is high; in addition, if the top surface of the concrete foundation bed 5 is processed unevenly, the compactness of the prefabricated parts and the top surface of the concrete foundation bed 5 is poor, the upper structure is unstable, and the integral stability of the structure is affected.
As shown in fig. 3 and 4, the embodiment provides a method for constructing a sealing system between a bottom member and an underwater concrete foundation bed, which includes the following steps:
step one, arranging a base groove 41 on an underwater bottom surface 4, and processing a foundation at a preset position of a cushion block 3;
step two, placing the cushion block 3 in the base groove 41, and adjusting the height of the cushion block 3 according to actual conditions;
thirdly, connecting the grouting pipe with the concrete guide pipe 2;
placing the component main body on the cushion block 3, and adjusting the plane position of the component main body;
and fifthly, injecting the underwater undispersed concrete into the foundation trench through the grouting pipe, the concrete guide pipe and the grouting hole.
When the base groove 41 is relatively flat, the second step may be replaced by adjusting the height of the cushion block 3 according to actual conditions and engaging the cushion block 3 with the bottom plate 11, and the fourth step may be replaced by placing the member body and the cushion block 3 together in the base groove 41 and adjusting the plane position of the member body. This completes the combination of the pad 3 and the member body and the connection of the grout pipe and the concrete pipe 2 before the member body enters the water, thereby simplifying the flow of the underwater work. After the underwater undispersed concrete is injected into the foundation trench, the cushion block 3 is also wrapped by the underwater undispersed concrete, so that the cushion block 3 becomes a part of the underwater concrete foundation bed. The height of the cushion block 3 in the second step and the third step is equal to the depth of the foundation trench 41, so that the underwater undispersed concrete is injected into the foundation trench 41, so that the undispersed concrete is tightly attached to the bottom plate 11, and certainly, a flexible material (such as anticorrosion wood, a high-performance rubber material and the like) can be placed on the top of the cushion block 3 to adjust the elevation of the member with the bottom on the cushion block 3. The method fully utilizes the self-leveling characteristic of the underwater undispersed concrete, realizes 'soft and hard touch', improves the compactness of the bottom-equipped member and the concrete foundation bed 5, ensures that the structure is more stable, does not need a diver to carry out underwater floating, reduces the workload and reduces the risk of underwater operation. The method is more suitable for complex conditions, such as uneven base groove 41, and the bottom surface positions of the belt bottom components and the like can be quickly and conveniently adjusted by adjusting the height and the position of the cushion block 3 before the belt bottom components are installed, so that the risk caused by the inclination of the belt bottom components and the like is avoided.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
