Description

Technical Field

[0001] The present invention belongs to the technical field of caissons, and particularly relates to a precast reinforced concrete caisson and an installation method thereof. Background Art

[0002] Reinforced concrete caissons are a type of foundation form commonly used in underwater or underground structure construction and are widely applied in projects such as ports, bridges, tunnels, sewage treatment plants, etc. Caissons are usually made of reinforced concrete, have high bearing capacity and stability, and can provide reliable support under harsh geological and hydrological conditions. Their construction process usually adopts the "caisson method", that is, the shaft structure is first fabricated and then sunk to the predetermined position by its own weight or external force to complete the construction of the foundation.

[0003] Reinforced concrete caissons are applied to various scenarios, but the scenario requirements vary greatly. After the existing precast reinforced concrete caissons are processed, due to the erection of steel bars, it is necessary to cut the steel bars when opening, and then the cutting of the solidified reinforced concrete is time-consuming and laborious. At the same time, when connecting according to the scenario requirements, the interface is not sealed, thus reducing the working performance of the reinforced concrete caisson. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a precast reinforced concrete caisson and an installation method thereof.

[0005] The technical solution adopted to solve the above technical problem is: a precast reinforced concrete caisson and an installation method thereof, including a main body, the main body includes a plurality of component plates, the component plates include component bodies, a groove is provided at the top of the component body, a convex block is fixedly connected to the bottom of the component body, and the inner wall of the groove is movably connected to the convex block;

[0006] Abutting plates are installed on both sides of the plurality of component plates, a grooved plate is installed on two of the component plates, and a support mechanism is installed inside the plurality of component plates.

[0007] Further, the abutting plate includes a plurality of concave teeth fixedly connected to one side of the component body, a plurality of convex teeth are fixedly connected to the other side of the component body, and the plurality of concave teeth are respectively engaged with the corresponding convex teeth.

[0008] Through the above technical solution, during use, the concrete caisson is divided into multiple component plates, which are spliced by multiple component plates, facilitating transportation during use, enabling quick splicing during use, and allowing selection according to the required specifications of the concrete caisson, making it more convenient to select the height. Additionally, during use, splicing is carried out through the connection plates, and the design of tooth connection can increase the contact area and the friction force of the joint surface, enabling each part of the caisson to be more firmly connected together, thereby improving the stability and resistance of the overall structure. Moreover, during the use process, due to the penetration of water flow, it can quickly absorb the water flow along the uneven teeth. Specifically, first, splice the multiple convex teeth on one side of the component with the concave teeth on the other side, and when reaching the last piece, use the extrusion method from the outside to the inside for splicing to make the overall ring have a certain stability. Subsequently, when the first layer of the ring is spliced, the convex blocks at the bottom of the component are inserted into the soil for easy stabilization. Then, the convex blocks at the bottom of the upper component can be inserted according to the grooves at the top of the component to complete the splicing and stacking.

[0009] Furthermore, the grooved plate includes circular holes opened in two of the components, and support ring plates are fixedly connected inside both of the circular holes.

[0010] Through the above technical solution, during splicing, one of the component plates can be utilized. Adding the grooved plate enables operations such as threading during the use of the caisson. At the same time, with the support of the grooved plate, the overall force is more perfect and it is not easily damaged. Specifically, circular holes are opened on the surface of one of the component plates, and then the support ring plates are placed therein to increase the overall stability.

[0011] Furthermore, the support mechanism includes two connection blocks fixedly connected inside the component. There is a cavity between the two connection blocks. A plurality of vertical steel bars are fixedly connected inside the component, and horizontal steel bars are fixedly connected inside the component. The cavity is located inside the component, and a plurality of vertical steel bars and a plurality of horizontal steel bars are cross-distributed. The two support ring plates are respectively supported and fixed to the corresponding cavities.

[0012] Through the above technical solution, during the manufacturing process, while using the support mechanism to stabilize the caisson, it can also save materials and provide heat insulation and cold insulation. Specifically, by arranging connection blocks up and down on the component to maintain normal connection and form an insulating layer to prevent water flow from entering. At the same time, a cavity is set inside for heat insulation, cold insulation, and water isolation. Subsequently, a plurality of vertical steel bars and a plurality of horizontal steel bars are used crosswise and connected by pouring concrete to maintain the overall stability.

[0013] An installation method for a precast reinforced concrete caisson includes the following specific steps:

[0014] Step 1: a prefabricated reinforced concrete body having a cavity inside and a plurality of vertical steel bars cross-connected with a plurality of transverse steel bars is prepared;

[0015] Step 2: Then, the concave teeth and the convex teeth on both sides are bound by equipment or bound through the cavity and multiple vertical steel bars and multiple horizontal steel bars, and then hoisted and transported to the installation location;

[0016] Step 3: The operator assembles according to the needs of the caisson, and the plurality of concave teeth are respectively meshed with the corresponding convex teeth to form a circle. At the same time, two components are selected, and support ring plates are fixed inside the two circular holes and installed therein, until the last component plate after the circle is installed, and it is squeezed from the outer circle to the inside;

[0017] Step 4: When the first circle is completed, select according to the height and arrange the grooves along the top of the component so that the protrusions at the bottom of the component are embedded in it, and assemble it around it until the required amount is completed. At this point, the installation of the prefabricated reinforced concrete caisson is completed.

[0018] The beneficial effects of the present invention are as follows: (1) The present invention can quickly install the small plates in prefabricated reinforced concrete by designing the component plates, connecting plates, slotted plates and supporting mechanisms, and can ensure the normal use function while adopting a hollow design, which is convenient for transportation and can be quickly transported, thereby speeding up the installation speed; (2) The present invention can be installed according to the needs of the caisson by designing the component plates and connecting plates, and can select the specifications of the caisson according to the connection between the grooves and the protrusions and the meshing between the teeth, thereby expanding the scope of application, and can be quickly installed and placed during transportation and installation, and can save time and labor by transporting small pieces. In addition, water leakage can be quickly consumed according to the unevenness of the teeth; (3) The present invention can save materials while ensuring the original use function when making the caisson, reduce penetration, and have functions such as heat insulation and cold insulation, and use horizontal and vertical steel bars for crossing, which can ensure the stability of the hollow design while ensuring a certain degree of firmness.
