Integrated water meter manhole (500)

Product Specifications:

Standard water meter manhole dimensions (internal): 560×510×680 or 560×510×980 (length*width*height, unit: mm); Manhole inlet size: main pipe dm63mm (connected with a flexible joint at the end); Manhole outlet size: branch pipe dm25mm or dm20mm; Welded water meter manholes can be customized to customer requirements.

Technical Requirements:

1. No leakage after 24-hour water-tightness test.

2. The pipeline system inside the wellbore undergoes a 0.6 MPa pressure seal test with no pressure drop.

3. The manhole covers maintain excellent insulation at -25°C, with no freezing observed in the internal piping and components inside the well.

Performance characteristics of water meter manhole:

1. This water meter well is made by plastic die casting and consists of three sections connected by sockets, making installation easy. The height of the well can be adjusted according to the depth of the frozen soil in different regions. The structure is compact with a small size, saving space. This water meter well realizes a centralized meter reading, modern water resource management model with one meter per household.

2. This well is fully sealed, preventing rainwater and debris from entering outside, thereby ensuring the cleanliness of the water meter and the accuracy of measurement.

3. The manhole cover design is unique, featuring a structure with both top and bottom covers, both equipped with anti-theft devices to ensure the security of both the cover and water meter against theft. The design of the top cover facilitates meter reading for meter readers, eliminating the need to open the large manhole cover each time.

4. Excellent water flow design with minimal resistance.

5. The design of the lockable valve prevents the phenomenon of using water without payment.

6. The well exhibits strong vertical load-bearing and anti-float capabilities. Thicker well walls, vertical reinforcing ribs, and a special wellhead design ensure the well's vertical load-bearing capacity, with ground bearing capacity exceeding 5 tons. Additionally, the weight of the well body is sufficient to overcome the buoyancy of groundwater.

7. Fast construction speed and short project duration. Traditional water meters are brick or cement cast, whereas this water meter well is plastic injection-molded and assembled with three sections connected by socket and spigot. Factory-intensive production ensures easy installation. As long as the construction conditions are met on-site, the construction speed is over 10 times faster than concrete wells and brick wells.

8. Long service life, exceeding 50 years, due to the use of PE and glass fiber composite materials for the well body, which are resistant to corrosion and have high rigidity.

9. Environmental Protection and Energy Efficiency. As this water meter well is produced on a factory's intensive scale, the quality of each process is controllable, resulting in excellent sealing performance for the well. This prevents sewage from渗入地下，thus protecting underground water resources, and also reduces the amount of wastewater treatment.

Welded Water Meter Well

In addition to the various advantages of integral die-cast well, the PVC-U welded water meter well offers greater flexibility compared to the integral die-cast type. It can be customized to different sizes according to customer requirements, and the number of branches and water meters can be matched arbitrarily. However, it should be noted that this type of water meter well is suitable for non-load-bearing locations; if bearing load is required, a separate load-bearing well mouth must be installed during installation.

Compared to traditional wells

One. Permeability Comparison

Traditional brick-lined wells pose an enduring challenge in terms of impermeability, with污水 leakage within the well and rainwater seeping through to form waterlogging, leading to difficulties in meter reading, pipeline maintenance, water quality safety hazards, and disputes over resident payments. This causes waste of both human and material resources for the water supply department.

The entire prefabricated plastic well is equipped with sealing rings, ensuring that both the inlet and outlet pipes are sealed to the well body, completely preventing any leakage. The gaskets at the well opening and cover are securely sealed. Every water meter well is factory-tested with an overall hydrostatic test (1mpa with no leakage), truly achieving the effect of preventing leakage underground and surface leakage above ground.

Section II: Safety

The old-style water meter well has a complex structure and a single performance. In cases of illegal water theft or refusal to pay water bills, the supplier cannot regulate the supply through the facilities. The plastic integrated water meter well covers are secured with anti-theft screws, and the well body is equipped with locking devices and control tools, which will enable the supplier to effectively control unauthorized water usage.

Three, Low Temperature Resistance

In northern regions during winter, the low temperatures often cause water meters in old brick wells to freeze and crack. However, the overall pre-fabricated plastic well covers are equipped with insulation and have excellent airtightness, maintaining the well temperature above the freezing point, ensuring the water supply facilities safely through the winter. Moreover, the height of the well can be adjusted and deepened according to local requirements to withstand even lower temperatures.

Four, low construction costs, minimal trenching required

V. Low maintenance costs

The difficulty of repairing old brick-lined wells is well-known due to numerous internal pipelines and accumulated water, causing maintenance personnel to be overwhelmed when entering the well for repairs. The integrated pre-fabricated plastic well features simple internal connections and allows for the complete removal of the water meter, thereby reducing the complexity of maintenance and the risk of damage. Moreover, most of the internal pipelines in the integrated pre-fabricated plastic well are integrated within the well body, and its sealed design further minimizes the failure rate.

Construction Requirements for Brick-lined Well

1. Must have transportation conditions for bricks, cement, and water sources.

Excavate a 3D trench with dimensions of approximately 150cm x 150cm x 80cm.

3. Required: gray bricks, compacted base layer, and more than 800 bricks for the internal diameter.

4. Cement wellhead with a matching load-bearing well cover, featuring one cover plate measuring 120cm x 150cm x 1.5cm.

5. The well assembly includes an inlet large frame, composed of six 150cm to 20mm tees and a 50mm blind flange.

6. Six groups of water meter assembly components (including shut-off valves, stop valves, check valves, water meters, and connectors) are installed and connected.

7. Construction period from fixed wellhead, cover, surface treatment, curing, and equipment assembly requires 5-7 days; post-completion, potential hazards include seepage and accumulation of wastewater, frozen water meters, short lifespan of assembled valves, and difficulty in maintenance.

Plastic water meter manhole construction requirements:

1. The well body measures 60cm in length, 55cm in width, and 80cm in height. Excavate a pit larger than the well body volume, suitable for construction.

2. The bottom foundation of the well is leveled and compacted with a sand and soil layer. The elevation of the water meter well top should be ensured not to be lower than the ground level based on the road, or slightly higher than the ground level.

3. The wellbore comes pre-assembled with a custom water diverter, water meter, magnetic valve, check valve, pipe fittings, and other components, eliminating the need for井下 operations. It can be connected to external pipelines with ease, featuring quick-connects on the main pipeline for convenient and fast installation.

4. Surround the water meter well with fine soil backfill, and compact it in layers.

5. The wellhead of the welded well has a recess of 10cm deep and 20cm wider than the well opening, filled with sand, stone, and cement, and equipped with convenient handles for easy lid removal.

6. After installation, cover the well lid and tighten the anti-theft bolts on the lid to ensure sealing and anti-theft properties.
