Abstract

The invention relates to the technical field of road construction, and particularly relates to a double-layer support inspection well. The double-layer support inspection well has the beneficial effects that an anti-theft special-shaped bolt arranged on the double-layer support inspection well provided by the embodiment of the invention plays a role in preventing a well cover from being stolen, the compact connection of the well cover and a lifting support is ensured by adopting clamping nails and clamping grooves so as to prevent the well cover from making noise when the well cover is rolled after the well cover becomes loose; a sub well cover arranged in the inspection well can prevent the well cover from falling after the well cover is broken or other foreign matters from falling into the well when the well cover is absent; and a support body is fixed on a wellhole by adopting fixed parts, so that the support body can be prevented from moving. The double-layer support inspection well is guaranteed in terms of theft prevention, noise prevention, falling prevention, displacement prevention and the like. When being installed, the inspection well is installed layer by layer to avoid excavation and repairing of asphalt concrete at lower layers. The installation technology of the inspection well is simple. A road surface around the inspection well has good wholeness, and the quality of the road surface is ensured.

Description

technical field

[0001] The invention relates to the technical field of road construction, in particular to a double-layer support inspection well. Background technique

[0002] At present, in recent years, accidents of casualties and vehicle collapse due to the damage of maintenance manholes on highways and urban roads have occurred frequently. Among them, serious vehicle overloading and repeated rolling are important reasons for frequent damage to manholes. A great security risk. With the rapid development of my country's communication industry, major operators attach great importance to the safety of communication wells, and the construction and maintenance units at all levels are very intensive in daily inspections and maintenance. Once they are found to be damaged by human wells, they will respond and deal with them in time to avoid further damage. destruction occurs. However, due to the width of the road occupied by the maintenance of man wells, the conditions of the c...
