Hot summer conditions may cause cracks in the poured concrete, which will seriously affect the quality of the entire construction project。How can we reduce the temperature during concrete pouring in summer?Chongqing Shiqiao Dinggu Construction Machinery Co., Ltd. put forward the following suggestions: 1.tangible料斗The following measures should be adopted to reduce the aggregate temperature in the material field: ① The aggregate of the finished material field, the stacking height should not be too low, and there should be sufficient reserve;② Take material through ridge;③ Build pergola, spray fog (except sand), etc。2.Pre-cooling coarse aggregate can be pre-cooled by air cooling, soaking water, spraying cold water and other measures。If water is used for cooling, there should be dehydration measures to keep the water content of the aggregate stable。3.When mixing concrete, cooling measures such as low temperature water and adding ice can be used。When adding ice, ice or ice chips can be used, and the mixing time can be extended appropriately。4.Reduce the temperature rise of concrete (1) shorten the transportation time of concrete, promptly smooth the concrete after warehousing, speed up the concrete warehousing covering speed, shorten the exposure time of concrete;② Concrete transport vehicles should have heat insulation and sunshade measures;3.tangible料斗用途It is advisable to use spray fog and other methods to reduce the air temperature around the warehouse surface.(4) Concrete pouring should be arranged as far as possible in the morning and evening, night and cloudy days;⑤ Before the concrete levelling after warehousing is completed to the next layer of concrete, it is appropriate to use thermal insulation to cover its top joint。Summer concrete in the construction process should pay attention to every step of preventive measures, only in this way can improve the quality of the overall construction project。
(1)云南tangible料斗Feeding system: composed of storage hopper and feeding equipment, the main function is to store materials and feed to the weighing hopper under the control of the control system。Method of feeding system: PLD800-1200 type, feeding for belt conveyor;(2) Weighing system: The weighing system is the key part of the batching machine, which is composed of weighing hopper, suspension equipment, weighing system sensor, batching controller, etc。(3)tangible料斗用途Electrical control system: The electrical control system is the core component of the batching machine, and its function is to complete the weighing, displaying, operating and completing various active batching sequences of the entire batching machine。The system is mainly composed of two parts: batching controller and strong current circuit。
云南tangible料斗Concrete is actually "concrete."。Concrete, referred to as "concrete (tong)" : refers to the aggregate cemented into a whole by the cementing material engineering composite material collectively。Generally speaking, the term concrete refers to the use of cement as a cementing material, sand, stone as aggregate;With water (with or without admixtures and admixtures) according to a certain proportion, by mixing, forming, curing and cement concrete, also known as ordinary concrete, it is widely used in civil engineering。It is made of cementing material, aggregate and water according to a certain proportion of preparation, by stirring vibration molding, under certain conditions of maintenance of artificial stone。tangible料斗Concrete is rich in raw materials,Low price,The production process is simple,So the use of more and more;At the same time, concrete also has high compressive strength,Good durability,Wide range of strength grades,Make it a very wide range of use,Not only used in various civil engineering,The shipbuilding industry,Machinery industry,Ocean exploitation,Geothermal engineering,Concrete is also an important material。The concrete pump is composed of a pump body and a conveying pipe。It is a kind of machine that uses pressure to transport concrete continuously along the pipeline, mainly used in house construction, bridge and tunnel construction。At present, it is mainly divided into gate valve concrete conveying pump and S-valve concrete conveying pump。The other is to install the pump body on the chassis of the car, and then equipped with a telescopic or flexed fabric rod, and composed of a pump truck。
云南tangible料斗When loading, the mixture to be stirred is installed in the hopper, the feeding system is started, the wire rope pulls the hopper to climb up, when climbing to a certain height, the hopper enters the loading rack, the hopper door automatically opens, and the material is unloaded into the mixing cylinder through the funnel。JS750 mixer mixing system is composed of motor, pulley, reducer, gear, mixing device, mixing cylinder and so on。The main motor is connected to the two-stage gear reducer through the belt, and finally through the two pairs of open gears respectively drive the two horizontal mixing shaft to rotate towards the same speed。The electrical control system needs to control the main drive motor of the JS750 mixer, the motor of the water supply system, the motor of feeding, unloading, etc。All electrical control elements are located in the distribution box。The electrical components in the distribution box are installed on an iron plate, which is safe and reliable, easy to operate and maintain。The discharge system is at the bottom of the mixer, and the discharge is carried out by a manual push rod。According to customer requirements, we can produce mixers in the form of electric push rod discharge。The connection between the discharge door and the mixing cylinder shall be sealed with a sealing plate.料斗用途The position of the seal plate can be adjusted to ensure the purpose of sealing。
