Standard Practice for Construction Joint of CP Type Rubber Waterstop
Hello everyone, today I introduce you to the CP type rubber waterstop. This belt type belongs to the middle-buried rubber waterstop and the other is the CB rubber waterstop. The scope of the two is different. The water belt is generally a CP type rubber waterstop (that is, the middle buried type non-porous type). The deformation joint water stop belt is generally a CB type rubber water stop belt (that is, a middle buried type hole type).
Construction joints are a hidden danger of water seepage and should be minimized. We often use waterstops to deal with construction joints. What are the steps and methods for handling construction joints with waterstops?
What is construction joint?
Because the joint surface formed by successive pouring of concrete is prone to various hidden dangers and quality problems, different structural engineering needs to be cautious in handling the construction joints. Construction joint: A seam that is left between the construction unit sections due to the needs of the construction organization. The construction joint is not a real “seamâ€. It is only because the post-cast concrete exceeds the initial setting time, and there is a joint surface between the concrete and the first poured concrete. This combination is called the construction joint.
CP type rubber waterstop construction joint construction method and steps:
A φ8 steel hole is drilled every 0.5 to 1.0 m along the axis of the invert lining. Pass the finished steel bar through the stop plate template, the inner side is fastened to the water stop half, and the other half of the CP type rubber water stop is placed on the stop plate. After the concrete is solidified, the stop plate is removed and the water stop belt is pulled. Straight, then bend the steel bar tightly to the water
Set water-expanding water stop strip in the construction joint; (b) external sealing water stop; (c) CP type rubber water stop belt
Before pouring concrete after construction, it is very important to clean the surface of the concrete in the early stage. Because of the long time difference between the two pourings, many impurities and fine sand are left on the surface. If the cleaning is not clean, it becomes the isolation layer and becomes the water seepage channel. The CP-type rubber waterstop should be used for the buried waterstop, but the thickness of the wall is required to be no less than 30cm. The above is the introduction of the construction method and steps of the CP type rubber waterstop for the construction joints. I hope that everyone can better handle it after reading it.
QUANTUM Bucket Elevators have successfully been installed in a wide range of applications and capacities. From process equipment, handling a few kg /hr to over 2000 t/hr with a vast range of materials. Whether your application requires a heavy-duty high capacity machine or an industrial process elevator for your factory.
We have a wealth of experience in designing the correct bucket elevator for your application and have a standard range of elevators, which can be specifically designed for, more specialised applications.
Our elevators have conveyed high temperature, high wear, abrasive, large lumpy, sticky non-flowing materials, as well as free flowing powders and granules. We supply a standard range of twin chain and belt elevators single or twin bucket design for high capacity applications such as grain, minerals and ore. The selection of the elevator depends on the material characteristics and IBS will be able to advise you and select the elevator most suited to your material and your application.
• Gravity elevators
• Positive discharge elevators
• Central discharge slow speed elevators
• Centrifugal elevators
Gravity Type Bucket Elevator
Quantum supply gravity discharge elevators and positive discharge elevators, supplied as close bucket discharge type, central discharge type, or Idler wheel discharge.
Generally a slow speed design gravity bucket elevator is primarily installed for elevating large lumpy & abrasive material. Our standard units are usually chain driven, either friction drive or toothed sprocket.
These elevators offer reliability with minimum wear & a positive discharge emptying of the bucket.
Centrifugal Type Bucket Elevator
Quantum standard range of centrifugal elevators are the most common type of elevator installed to most industries supplied in both belt type or chain type depending on material characteristic and the capacity being elevated and in some case the feeding method of the elevator.
Conveying type
• Segmented tooth sprocket chain type, twin chain or single dropped forged link chain
• Friction chain type elevators, European rolled chain
• Belt elevator. Using rubber belt or 100% polyester solid woven belt, nylon and steel woven belt Typical Construction
• We supply Single leg or Double leg elevators
• Lagged head Pulley
• Slatted return pulley for sticky materials
• Segmented removable sprockets for chain elevators
• Segmented and removable friction pulleys for friction drive elevators
• Fabricated boot and head section assemblies
• Fabricated 3.0m long nominal casings c/w with self-supporting frame and lateral support frames
• Dust tight sealed flanges
• Screw or counterweight tail end take up
Whether the elevator is best suited for toothed sprocket design, friction wheel on conventional belt, IBS will be able to assist with correct selection for the most reliable, maintenance free and cost effective machine to suit your material characteristic and conveying capacity for your particular application.
Types of Buckets readily available
IBS Supply a range of standard off the shelf buckets in a variety of sizes and materials.
Selection of bucket type will depend on material, material characteristics and application. Typical IBS buckets would be plastic-nylon or polyurethane and can be provide FRAS, mild steel fabricated or pressed, stainless steel fabricated or pressed and wear tips for abrasive materials.
Safety and maintenance
• Our equipment is supplied mandatory with anti-roll back device in full load condition
• All inspection doors are fitted with safety limit
• Safety factor of minimum 12: 1 to rated chain pull to installed chain or belt pull under full load stall conditions
For some materials and specific applications, Quantum will design in accordance with Australian standards, suitable explosion venting and will design the structure of the elevator to suit the required application. Typical material that requires this consideration would be sugar, flour, grain and coal.
Standard features for all our bucket elevators
• Qty2 1000mm long inspection doors in conveyor leg and return leg in twin leg elevators for easy inspection of belt or chain and replacement of buckets. Inspection hatch will be provided with bolted mesh screen and safety limit switch
• Qty 2 inspection doors in head section, fitted with safety limit switch• Fully removable split head top section.
• Clean out and inspection doors in Boot section. Self-cleaning boot section optional.
• Under speed sensor and flag disc
• Belt tracking sensor or switch for belt Bucket Elevators
• All our equipment is designed to meet Australian Standards
• Selection of correct conveying velocity and material trajectory for centrifugal elevators is critical to the successful operation of a bucket elevator
• Standard wear plates on boot in-feed and head chute discharge.
• Designed to operate no more than 70% water level of selected bucket at normal operation.
• Installed power capable of full load start up under full bucket surge capacity.
• Our bucket elevators are designed for dust tight design, with suitable dust extraction points
• All our bucket elevators are designed to be self-supporting and are provided with lateral support bracing at approx. 10m centres
Replacement parts service
We can provide a range of standard bucket elevator parts using our standard head and tail pulley assemblies, conveyor belting, elevator butt straps, conveyor bolts and fittings, belt-splicing fittings.
Coupled with our range of standard steel and plastic buckets, elevator chain and fittings, belt tracking switches and sensors we will keep your business moving--
Quantum can provide a customised service contract using experience technicians with many years` experience in servicing and troubleshooting bucket elevators in most states.
