Are you still troubled by these problems?

Manhole covers stolen but undetected for 24 hours, leading to frequent pedestrian falls.
Covers washed away during heavy rains, causing severe waterlogging with delayed responses.
High costs of manual inspections, exceeding millions annually for maintenance.
Outdated traditional cover management, resulting in elevated public liability risks.

Now, Tiegu offers you solutions and products!

In recent years, incidents of manhole cover theft and damage from rolling pressure have occurred frequently, compromising road and facility safety. To better protect public infrastructure and safeguard key underground resources, there is an urgent need to adopt new technologies and models to strengthen manhole cover safety management. Against this backdrop, the demand for intelligent manhole cover management has emerged.

Cooperative Cases

A district in Thailand: 1,200 sets of smart covers used for 1 year, resulting in zero cover-related accidents and a 60% reduction in patrol personnel.
A district in Bangladesh: Flood response time shortened from 2 hours to 15 minutes during the rainy season, with an 82% drop in waterlogging complaints.

Four Core Functions: Comprehensive Intelligent Management

The main functions of smart manhole covers include:

1、Sensor Monitoring

Equipped with built-in sensors, smart covers real-time monitor traffic conditions, environmental data, and their own usage and location information.

2、Data Storage

Data is stored in real time on cloud platforms, facilitating data collection, analysis, and application by urban managers and public service institutions. The platform also uses big data analysis and AI algorithms to analyze and predict urban traffic and environmental conditions.

3、Networked Control

Smart covers connect to urban internet via wireless communication technology, enabling real-time data transmission and networked control. They can also be remotely opened/closed for convenient management by urban staff.

4、Automatic Warning and Linkage

When abnormalities occur (e.g., theft, damage, overflow), the system automatically alarms within 90 seconds, synchronously pushing alerts to management platforms and responsible personnel, and linking relevant departments (e.g., urban management, drainage stations) to initiate emergency responses.

Application Scenarios

Smart manhole covers can be applied in the following areas:

Traffic Management

They monitor and analyze traffic data (flow, speed) to provide real-time information and predict congestion, offering a scientific basis for smooth urban traffic.

Environmental Monitoring

They detect urban environmental data (noise, odor, temperature, humidity) to reduce pollution and improve urban livability.

Natural Disaster Management

They monitor sewer flow to warn of flood, earthquake, and other disaster risks, enhancing urban emergency response capabilities.

Public Safety

They eliminate "urban traps" caused by missing covers, reduce public liability risks, and cut public liability costs by 65%.
