Description

Technical Field

[0001] This invention belongs to the technical field of repairing damage around manhole covers in municipal pipeline inspection networks, specifically relating to a rapid repair device and method for damage around manhole covers in municipal pipeline inspection networks. Background Technology

[0002] As roads age or due to inadequate construction quality control, some manholes in urban roads experience subsidence and cracks or uneven settlement in the surrounding pavement during use. This severely impacts driving comfort and road aesthetics; significant road deformation also endangers traffic safety, causing damage to tires and wheels, and even negatively affecting the city's image. Therefore, timely and rapid repair of damaged manholes is necessary, while ensuring repair quality to improve road comfort. Traditional repairs of damaged concrete around manholes are often crude, using simple and rough techniques, taking up considerable time and disrupting traffic. Poor repair appearance also negatively impacts the city's image.

[0003] To address this, patent specification CN116163177A discloses a rapid repair method for damaged areas around manhole covers in municipal pipeline networks. The steps include: pre-preparing steel fiber reinforced concrete by construction personnel; analyzing the damage around the manhole cover on-site, drawing lines and cutting seams using a circular tool; using a pneumatic hammer to remove the damaged portion within the lines; pouring and smoothing the bottom layer of concrete; installing a reinforcing mesh; pouring and smoothing the middle layer of concrete; fixing the manhole ring with a lifting bracket and installing anchor bolts to secure the manhole cover; pouring the top layer of concrete to the level of the manhole cover, smoothing it, and finishing the interior surface; using a heating device to cure the newly poured road surface; after the concrete reaches the required strength, reinforcing the upper layer around the manhole with asphalt concrete; cleaning and reopening the road to traffic. The specification also discloses a heating device used in conjunction with this method, which allows the newly poured concrete around the damaged road surface to quickly reach its strength, completing the manhole repair work in the shortest possible time and reducing the time spent on traffic disruption during manhole repairs.

[0004] However, this method and device for rapid repair of damage around manhole covers in municipal pipeline networks still has shortcomings. First, it requires analysis of the damage around the manhole cover on-site, which places high demands on operators and is not conducive to the implementation of standardized maintenance. Second, it requires on-site concrete pouring and long-term curing, resulting in a long overall repair time and significant traffic disruption. Therefore, it needs to be optimized and improved. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and to provide a device and method for rapid repair of damage around manhole covers in municipal pipeline inspection networks.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] This invention provides a rapid repair device for damaged areas around manhole covers in municipal pipeline inspection wells, including a walking base as a carrier, a rectangular column fixed to the upper end of the walking base, two sets of guide rails symmetrically arranged on the front and rear sides of the rectangular column, vertical racks symmetrically arranged on the left and right sides of the rectangular column, and a first movable seat and a second movable seat respectively installed on the left and right sides of the rectangular column.

[0008] The first movable seat has a first guide groove that mates with the corresponding guide slide rail.

[0011] Furthermore, in the aforementioned rapid repair device for damaged manhole covers in municipal pipeline inspection networks, the concrete hole opener includes a cylindrical tubular structure with one end open, and the ends of the cylindrical tubular structure located in the opening area are provided with protruding blades.

[0012] Furthermore, in the aforementioned rapid repair device for damaged areas around municipal pipeline manhole covers, the distance between the two concrete breaker picks is less than the opening diameter of the concrete hole opener, while the distance between the two concrete breaker picks is greater than the diameter of a standard municipal pipeline manhole cover.

[0013] Furthermore, in the aforementioned rapid repair device for damaged areas around manhole covers in municipal pipeline inspection networks, the concrete crushing pick is a hydraulic crushing roller.

[0014] This invention also provides a method for rapid repair of damage around manhole covers in municipal pipeline networks, based on the aforementioned rapid repair device for damage around manhole covers in municipal pipeline networks. The method includes the following steps:

[0015] 1) Adjust the position of the walking base so that the concrete hole opener is directly above the damaged municipal pipeline inspection well cover; the first drive roller tooth in the first movable seat rotates, causing the first movable seat to move vertically downward, while the first motor drives the concrete hole opener to rotate, so that a ring cut is formed around the municipal pipeline inspection well cover; the first movable seat is reset.

[0016] 2) Adjust the position of the walking base so that the concrete breaker is directly above the area between the annular cut and the municipal pipeline inspection well cover; the second drive roller in the second movable seat rotates, causing the second movable seat to move vertically downward, and at the same time the concrete breaker starts, realizing a single two-point breaking operation; after each breaking operation, the second drive roller rotates to drive the second movable seat to move vertically upward, and at the same time the second motor drives the two concrete breaker to rotate a certain angle, and then the breaking operation is performed again; repeat the above steps until the concrete layer in the area between the annular cut and the municipal pipeline inspection well cover is broken, and the second movable seat resets; remove the broken material to form an annular installation area;

[0017] 3) Install the annular precast concrete seat and the annular reinforcing steel ring in sequence in the installation area. The annular reinforcing steel ring is assembled with the annular precast concrete seat by connecting screws.
