Problems solved by technology

However, due to the large number of wells, if monitoring equipment is installed in each place, the monitoring cost will be greatly increased
At the same time, since wells are often located in the middle of the road, if monitoring facilities are installed, road traffic will be affected, and passing vehicles and pedestrians will cause damage to the monitoring facilities.
Therefore, it is not practical to install electronic monitoring facilities for ground wells

Embodiment 1

[0032] Embodiment 1: see figure 1 , figure 2 , the explosion-proof security inspection of the present invention is made up of rubber surface layer (1), rubber bonding layer (2) and antisticking layer (3) with manhole cover rubber seal, and its profile is that one side is long 72mm, and its top edge is the approximate square of arc. The rubber surface layer (1) is made of vulcanized rubber sheet with ethylene propylene diene monomer (EPDM) as the main material, and its thickness is 1 to 2 mm. Its production process is:

[0033] Use the usual rubber mixing method to mix each raw material into the required rubber compound, then press the rubber compound into a rubber sheet with a thickness that meets the requirements with a calender, and then vulcanize it at 143°C for 10 years with a flat vulcanizer. The vulcanized rubber sheet is produced in minutes, and finally cut with a cutter or punched into a rubber surface layer (1) with a mold. The rubber composition components of the...

Abstract

The invention discloses a well cover rubber seal strip used for anti-explosion safety inspection. The well cover rubber seal strip is composed of a rubber surface layer, a rubber bonding layer and an anti-cohesion layer, wherein the front side of the rubber seal strip is printed with warning marks and computer code information of the seal strip; the part that the rubber surface layer faces to the rubber bonding layer is provided with two groups of pre-split ports composed of discontinuous arc-shaped carved patterns in parallel; the well cover rubber seal strip used for the anti-explosion safety inspection is adhered on various underground well sealing parts of the anti-explosion safety inspection; and if someone opens a well cover, the rubber seal strip is torn along the pre-split ports, and cannot recover, so that security personnel are prompted that the security status of the underground well is damaged. The well cover rubber seal strip used for the anti-explosion safety inspection is simple in structure, easy to implement and convenient to use, and contributes to preventing terror and damage activities in public places and maintaining social security.

Description

technical field [0001] The invention relates to a manhole cover rubber seal for explosion-proof security inspection, which belongs to the fields of rubber product manufacturing technology and public management and safety. Background technique [0002] Underground public facilities such as water supply, heat supply, electricity, communication and rainwater drainage distributed in urban roads, squares and other areas. These facilities are equipped with wells for maintenance and construction. These wells are hidden and have a large enough underground space, which is easy to hide people or objects, and is easy to be used by terrorists to store or place explosives, causing safety hazards in public places. Therefore, facilities such as underground wells are the focus of the explosion-proof security inspection by the public security department. However, after the security check, the manhole cover often needs to be opened for construction due to the maintenance of underground facil...
