9Backfilling: Use concrete to fill the gaps between the steel grooves of the vehicle bottom scanner and the pit body, as well as between the pipes and the cable troughs. When backfilling concrete, avoid applying excessive force to prevent the steel trough from moving, which may cause the steel trough of the vehicle bottom scanner to shift. The protruding part of the steel groove of the vehicle underbody scanner and the road surface should be plastered with concrete to form a slow slope. The upper part is made into a smooth surface.

10Maintenance work: Do a good job in concrete maintenance to ensure72No vehicles are allowed to pass above within hours. If vehicles need to pass through during the construction process, steel plates should be used for covering. The initial setting and final setting of cement are affected by temperature. The lower the temperature, the longer the setting time required. Therefore, when constructing in low-temperature conditions, measures should be taken to keep warm to ensure the quality of the concrete. In hot weather, the newly set cement should not be exposed to too much sunlight. A sack or absorbent material should be laid on it and water should be scattered on it.

11For the distribution cabinet of the fixed vehicle bottom security inspection system: Build a cement structure with a length of at the position of the fixed distribution cabinet80cmThe width is60cmThe height is10cmThe concrete island is waiting to be found72After the cement has solidified, place the distribution cabinet on the cement island and fix it with expansion screws. Concrete has a few days to set. During the construction process, when vehicles pass by, the concrete may need to be covered with steel plates during its curing period.
