A water‑seal manhole is a supporting structure for rain‑sewage, chemical industry and sponge‑city pipe networks. Its core function relies on accumulated water inside the well to form a water seal barrier. Functions Specification: 1200*1200*315*315 Water‑Seal Manhole Key Application Notes Quick Comparison An inspection manhole is only for maintenance access. A water‑seal manhole focuses on water‑sealing […]
This intelligent irrigation pressure regulator serves as the water‑pressure heart for smart irrigation. 20‑100 PSI adjustable range with transparent viewing window stabilizes water pressure, avoiding poor atomization, pipe bursts and solenoid valve damage. Suitable for greenhouses, golf courses and high‑standard farmland retrofits.
Hydrostatic pressure testing is the key quality inspection step after PE water supply pipe installation. This article introduces 5 official standard rules for PE pipe pressure test pressure value, test section length, equipment requirements and on-site operation specifications to guarantee pipeline construction quality.
This article introduces the standard ring stiffness test method for double-wall corrugated pipes, covering test pipe installation, load application, strain data recording and ring stiffness calculation, helping analyze and optimize pipe structural performance.
Rainwater infiltration channel is an effective underground storm‑water management facility widely used in sponge‑city construction. It collects surface runoff and seeps rainwater into surrounding soil to recharge groundwater, relieve municipal drainage pressure and purify stormwater. This guide explains its definition, components, types, core functions, key design points, applicable scenarios and maintenance precautions.
This article introduces the complete standard construction steps of PP module rainwater harvesting tanks, including site preparation, foundation treatment, module installation, sealing, pipeline layout, inspection, backfilling and daily maintenance. The professional installation guide ensures stable, leak-proof and long-term operation of underground rainwater collection and storage systems.
This 4G decoder controller is a professional automatic control device tailored for sponge city rainwater harvesting and irrigation projects. Equipped with a built-in 4G data SIM card, it supports real-time remote operation via mobile phones and computer mini programs. Featuring two hardware configurations of pure 4G and 4G+WiFi dual communication, it ensures stable signal connection for outdoor open-air scenarios. The controller is natively compatible with DC12V/24V pulse and normally closed solenoid valves for direct driving, while AC solenoid valves require an additional relay conversion module. It is widely applied in outdoor unattended rainwater collection projects with stable performance and simple operation.
