Hydraulic Dam
Hydraulic Dam: The Smart Choice for Modern Water Management As a revolutionary adjustable overflow dam, the hydraulic dam leverages hydraulic systems to control dam lifting and lowering, enabling precise regulation of water level and flow . Unlike traditional fixed dams, it combines flexibility, durability, and eco-friendliness, making it the preferred solution for diverse scenarios including urban flood control, agricultural irrigation, hydropower generation, and landscape construction .Our hydraulic steel dam features a seamless steel panel design (Q355ND weather-resistant steel) that eliminates middle support piers, ensuring unobstructed flood discharge and navigation . With 5-15 minutes fast response time, 30-50 years lifespan, and minimal maintenance requirements, it delivers long-term value for both small rural projects and large urban water management systems .

Hydraulic Lifting Dam
AbstractThe hydraulic lifting dam is a high-efficiency movable water-retaining structure driven by a hydraulic system, which integrates the advantages of traditional rigid dams and flexible rubber dams. Composed of dam panels, hydraulic cylinders, control systems and anchoring components, it realizes precise adjustment of the dam body height through the extension and retraction of hydraulic cylinders. Featured by stable structure, accurate water level control, fast flood discharge response and good ecological compatibility, this dam type is widely applied in river regulation, flood control, irrigation water diversion and urban landscape water conservancy projects. Compared with inflatable rubber dams and self-acting flap dams, it has stronger load-bearing capacity and longer service life, making it an ideal choice for medium and large-scale water control projects.

Inflatable flexible membrane dam (EDPM)
AbstractAn inflatable rubber dam is a flexible hydraulic engineering structure composed of a high-strength synthetic fiber fabric core and a rubber-coated exterior. It achieves water retaining and discharging functions through inflation or water filling. Characterized by simple structure, short construction period, low cost, flexible operation and ecological friendliness, this type of dam is widely applicable to scenarios such as flood control, farmland irrigation, urban landscaping, river regulation and temporary cofferdams. Compared with traditional rigid dam structures, inflatable rubber dams can adapt to complex terrain conditions. Moreover, they can be rapidly deflated during flood discharge, which significantly reduces the risk of flood impact. As a result, inflatable rubber dams have become a new type of cost-effective and functional water control equipment in modern hydraulic engineering.

Inflatable rubber dam
Step-by-Step Procedures for Replacement of Inflatable Rubber DamPre-replacement Preparation & Site SurveyConduct a comprehensive on-site inspection to confirm the dam’s installation dimensions, foundation condition, anchor bolt layout, and surrounding water conservancy facilities.Prepare the new inflatable rubber dam bag (matched with design parameters), sealing components, anchor bolts, inflation system, and professional construction tools (such as cranes, inflation pumps, wrenches).Formulate a construction plan, including water blocking and drainage schemes, and set up safety barriers and warning signs around the construction area to isolate the construction site.Cut off the power supply of the original dam’s inflation and control system, and release residual gas and water in the dam bag to ensure safe operation.

Cross-sea bridge pot bearings GPZ1250GD
Pot bearing SPZ1250GD is a medium-load, guided-fixed type component, optimized for medium-span bridge projects that need directional displacement control and basic durability. Its key application scenarios are as follows:Urban Overpasses & FlyoversIt resists lateral forces from crosswinds and vehicle centrifugal force (thanks to restricted transverse displacement ≤ ±5 mm), while allowing ±20 mm longitudinal movement to adapt to temperature changes—ideal for busy urban traffic structures.Rural/Suburban Highway BridgesSuitable for bridges with spans of 10–30 meters. Its 1,250 kN load capacity supports heavy trucks, and the -40℃~+60℃ temperature range adapts to seasonal fluctuations in most rural areas.Small River-Crossing BridgesWith hot-dip galvanization and EPDM seals, it resists humidity and rainwater corrosion. The guided design prevents lateral slippage caused by water flow impact, ensuring long-term stability.Industrial Access BridgesIts high horizontal load capacity (≥ 375 kN) and wear-resistant PTFE sliding plate handle frequent heavy equipment (e.g., 50-ton trucks) passage, meeting the needs of factory or logistics park access.In short, SPZ1250GD excels in scenarios requiring a balance of load-bearing, directional control, and basic corrosion resistance—covering most non-extreme environment medium-span bridges.

Basin type rubber support GPZ1000GD
Step 1: Basic DefinitionPot bearings are high-performance load-bearing components designed for large-span infrastructure. They mainly support heavy structures and adapt to dynamic stresses, widely used in transportation and construction projects.Step 2: Core Structure (Key Components)Simplified 3-part structure:Cast Steel Basin: Main body for bearing large vertical/horizontal loads;PTFE Slide Plate: Low-friction layer (PTFE = polytetrafluoroethylene) to allow smooth displacements;Sealing/Cushion Parts: Rubber rings (anti-corrosion/dust) or elastic pads (shock absorption).Step 3: Core FunctionsLoad Transfer: Stably pass heavy loads (e.g., train, bridge girder weight) to foundations;Displacement Adaptation: Accommodate movements from temperature changes or vibrations (no structure cracking);Durability: Resist wear, corrosion (for coastal projects), and seismic impacts (in earthquake zones).
