Problems solved by technology
[0002] Due to structural defects or negligence in construction, the well cover and the road surface are not flush enough for the inspection entrance well tools of underground pipelines (including cables, natural gas pipelines and sewer pipelines). After a period of use, the periphery often cracks or Subside into a round pit, causing the well cover to not be tightly closed, causing rainwater or dirt to deposit and flow into the well; the vehicle often bumps and generates noise when driving
In addition, manhole covers are often stolen by lawless people, but they are not replaced in time, which increases the risk of accidents involving pedestrians or vehicles in wells

Embodiment Construction
[0022] Depend on figure 1 The well tool is composed of a well ring 1, a well cover 2, a bolt 3 and a nut 4, and the well ring 1 is fixed on the concrete well ring seat 7 with bolts 5 and nuts 6.
[0023] Depend on figure 2 The surface of the well cover 2 has hexagonal pattern 8 and U-shaped convex ribs, and the convex ribs are also used to cast the names and numbers of well tools, such as cable wells, sewer and gas pipeline wells, etc. The surface of the well circle 1 is evenly distributed on four sides A slotted hole 10, well cover 2 has slotted hole 11 in addition (representing slotted hole is upright in the figure, also can be arranged in row shape in fact), and this hole is used for removing or installing well cover 2 with tool.
[0024] Depend on image 3 , the well cover 2 bottom surface has a well-shaped convex rib 12 connected with the peripheral annular rib 13, and the well cover 2 has four holes 14 and a trademark pattern 22.

The invention relates to an embedded type well tool. A well ring of the well tool is fixed on a well ring seat by a bolt and a nut, and a well cover is fixed on a step of the well ring by a bolt, wherein the step of the well ring passes through a bolt, the upper part of the bolt and the side face of the well cover are provided with cross holes; a pin is inserted in the cross holes, and one end ofthe pin is welded and smoothed and parallel to the side face of the well cover; the tail end of the bolt is embedded in a shallow groove of the well cover to form an embedding and locking knot so as to ensure that the well cover is not easy to steal and guarantee that pedestrians and vehicles cannot fall into the well to cause accidents. In addition, during construction, the surface of the well cover is consistent with the gradient of a road surface as much as possible so as to ensure that the vehicles can steadily run without bumping and vibrating and reduce the generation of noise.
Description
technical field [0001] The invention relates to a mosaic type well tool, which adopts a mosaic lock fixing structure, and is a safe and anti-theft well tool. Background technique [0002] Due to structural defects or negligence in construction, the well cover and the road surface are not flush enough for the inspection entrance well tools of underground pipelines (including cables, natural gas pipelines and sewer pipelines). After a period of use, the periphery often cracks or Subside into a round pit, resulting in lax sealing of the well cover, causing rainwater or dirt to deposit and flow into the well; the vehicle often bumps and generates noise when driving. In addition, manhole covers are often stolen by lawless people, but they are not replaced in time, which increases the risk of accidents involving pedestrians or vehicles in wells. [0003] In 2004, I applied for a patent according to the situation. The patent number is 20040077660.1, which was well received by the ...
