Description

Technical Field

[0001] This utility model relates to the field of municipal construction manhole cover installation technology, specifically a casting mold for manhole cover installation. Background Technology

[0002] Currently, the new six-proof manhole cover is widely used in municipal roads due to its advantages of shock resistance, noise reduction, theft prevention, slip resistance, displacement prevention, and settlement prevention. The connection between the six-proof manhole cover and the manhole body is a socket-type connection that does not directly affect the manhole opening. The support flange of the six-proof manhole cover bears the load pressure from the road surface and distributes it to the road structural layer, reducing the load on the manhole body by more than 80%. This effectively reduces the possibility of manhole opening damage or manhole cover subsidence. It also places higher demands on the road structure beneath the support flange of the six-proof manhole cover. The cast-in-place base can effectively connect with the six-proof manhole cover. The manhole cover's support flange surface fits perfectly, and the grout can completely fill the gaps below and around the support flange, forming a uniform and continuous support layer. The support layer has high load-bearing capacity and impact resistance, which can reduce the maintenance work of the road structure in the later stage and effectively prevent settlement. However, the on-site formwork for setting up the pouring cavity is cumbersome. The size and quality of the formwork are inconsistent, which makes it difficult to estimate the amount of grout used. In addition, the formwork needs to be installed and disassembled many times, which requires a lot of repetitive labor. Therefore, in order to solve the above problems, this application proposes a pouring mold for manhole cover installation. Utility Model Content

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6 The manhole cover installation casting mold shown includes a first mold ring 1 and a second mold ring 2 symmetrically arranged to form a ring body. One end of the first mold ring 1 and the second mold ring 2 are connected by a hinge, and the other end is connected by a locking buckle. At least one grouting port 3 is fixedly provided on the first mold ring 1 and the second mold ring 2 respectively. A hinged forming cutting component 4 is provided at the port of each grouting port 3. The forming cutting component 4 can rotate around the hinge axis. The number of grouting ports 3 can be adjusted according to the size of the grouting ports 3. In the embodiment of this application, one grouting port 3 is provided on the first mold ring 1 and the second mold ring 2 respectively.

[0025] The forming cutting component 4 includes a connecting frame 4-1 and a sliding cutting plate 4-2. The connecting frame 4-1 is fixed to the first mold ring 1 or the second mold ring 2 by a hinge seat. The sliding cutting plate 4-2 is movably disposed within the connecting frame 4-1 and can slide back and forth along its frame, or it can be removed along a slide rail. When the forming cutting component 4 covers the grouting port 3, the connecting frame 4-1 is in contact with the grouting port 3, and the sliding cutting plate 4-2 can be pulled outward to expose the grouting port 3 for pouring operations. When the sliding cutting plate 4-2 is pushed inward, it is limited by the outer edge of the grouting port 3. The connecting frame 4-1 is a U-shaped frame with one end open. Its open end is hinged to the hinge seat by a hinge shaft and can rotate around the hinge shaft. A sliding groove extending to both ends is provided on the inner side wall of the U-shaped frame. The sliding cutting plate 4-2 is disposed on the sliding groove and can slide back and forth along it, or it can be pulled outward along the sliding groove to remove the sliding cutting plate 4-2. The sliding cutter 4-2 includes an arc-shaped cutter 4-2-1. Slider 4-2-2 is symmetrically arranged on both ends of the arc-shaped cutter 4-2-1. The slider 4-2-2 cooperates with the slide groove. The sliding cutter 4-2 is set on the connecting frame 4-1 by the slider 4-2-2 being locked in the slide groove. The sliding cutter 4-2 can slide and cut the initially set castable along the slide groove. A handle 4-2-3 is fixed on the arc-shaped cutter 4-2-1 between the two sliders 4-2-2. Pushing the handle 4-2-3, the arc radius of the arc-shaped cutter 4-2-1 is the same as that of the first mold ring 1 or the second mold ring 2, and the arc chord length is less than the width of the grouting port 3, ensuring that the arc-shaped cutter 4-2-1 can slide smoothly in the grouting port 3 to cut the castable.

[0026] like Figures 1 to 3 As shown, the grouting port 3 is inclined on the outer surface of the first mold ring 1 and the second mold ring 2, and its inclination is set between 30° and 50°. This allows the grouting port 3 to store a certain amount of grouting material while facilitating the smooth flow of the grouting material into the cavity formed by the first mold ring 1 and the second mold ring 2.

[0027] The diameters of the first mold ring 1 and the second mold ring 2 match the outer edge of the manhole cover, and the grouting port 3 is exposed on the outer side of the outer edge of the manhole cover. Furthermore, a patch plate 1-1 is provided on the inner side of the connection between the first mold ring 1 and the second mold ring 2. The patch plate 1-1 is fixedly connected to the first mold ring 1 and overlaps with the second mold ring 2, which can make the connection between the first mold ring 1 and the second mold ring 2 more stable. At the same time, the patch plate 1-1 can prevent cement grout from leaking from the connection, which could cause the mold to deform or connect into one piece during the solidification process, making demolding difficult. Several reinforcing ribs (not shown in the figure) can also be provided on the outer side of the first mold ring 1 and the second mold ring 2 to enhance the strength of the first mold ring 1 and the second mold ring 2 and prevent deformation caused by repeated installation and disassembly.

[0028] Workflow: Unlock the connection between the first mold ring 1 and the second mold ring 2. Place the first mold ring 1 and the second mold ring 2 around the support flange of the six-proof manhole cover, making the first mold ring 1 and the second mold ring 2 flush with the outer edge of the support flange to avoid misalignment. The grouting port 3 is exposed outside the support flange for pouring cement grout. Pull the sliding cutting plate 4-2 of the forming cutting component 4 outward to pour cement grout into the first mold ring 1 and the second mold ring 2 through multiple grouting ports 3. After the cement grout is flush with the bottom surface of the support flange, slide the sliding cutting plate 4-2 inward to cover the grouting port 3. Depending on the difference in grout composition, wait 15-30 minutes for the cement grout to initially set. When the forming cutting component 4 is rotated upward 90° to a vertical position, push down the handle 4-2-3 to make the sliding cutting plate 4-2 cut the initially set cement grout downward. Then, the first mold ring 1 and the second mold ring 2 can be removed for the next manhole pouring.
