The curb machine is the special equipment which uses the asphalt mixture (cement concrete) to build the road kerb and the water blocking belt. The automatic clutch and reducer are used as the transmission mechanism. The operation is simple and convenient, and it is more suitable for production operation of the first-line worker, widely applies to the high grade highway and the municipal road kerb and the water blocking belt one time molding.Non-standard size can be customized and please communicate with us in advance. The construction period will take about 2 days.
Operation principleï¼?A spiral blade is installed in front of the forming die. The blade is continuously rotating, and the cement concrete (asphalt sand) is continuously pushed into the forming die to press and form the kerb (the road edge stone and water blocking belt). The reaction force of the cement concrete (asphalt sand) to the spiral blade push the machine forward.
I beam cold bending machine, also called I beam bender, has the advantages of high efficiency, no need for hot processing, high strength of processed arch frame, convenient transportation and so on. It is widely used in the construction of tunnels, subways, hydropower stations, underground caverns and other industries.It is an ideal equipment for steel arch frame manufacturing.
The bending material of this kind of machine is not only for I beam, but also suitable for miner steel, U-shaped steel, C-shaped steel, angle steel, channel steel, track, square steel, steel pipe and other section steel. It allows them to arch, change diameters, and bend at fixed angles.
5 necessary factors and 2 notes for selecting I beam bending machine
(1) The diameter of three top rollers: if it is thin, then it is easy to skid because of small contact surface and easy to deform when bending non-standard steel.
(2) Diameter and stroke of oil cylinder: diameter and stroke determine the size of pressure and the adjustability of bending radius.
(3) The thickness of platform steel plate and the quality of frame: it determines whether the deformation occurs or not when bending large-scale steel.
(4ï¼?The power of the motor and the quality of the reducer.
(5) Manufacturer's production scale and service.
Note 1:The type,model and material of the steel.
Note 2:The radius of the bending: It is necessary to find out whether the bending radius conforms to the cold bending coefficient of the steel. Every steel has its own cold bending coefficient. If its cold bending coefficient is exceeded, the steel will deform and the internal structure of steel will be changed,and the quality of steel will be reduced.
With the development of expressway and domestic mechanical manufacturing technology, Slipform kerb machine machine equipment technology has been introduced to China from abroad, which has been applied to highway kerb construction and broken through the traditional manufacturing mode. With extremely high site versatility, it can adapt to all kinds of harsh working conditions. It can be produced on site, thus eliminating the need to rent the prefabrication site and the pre-preparation work. And avoiding the waste of materials in the prefabrication process and the loss in the transportation and site installation.
Product Advantage:
The production of kerb machine breaks the original operation mode and produces on site, which avoids the waste of prefabricated materials, as well as the loss during transportation and site installation, and saves by about 30% of raw materials. Based on the calculation of kerb of 1m3 concrete, kerb machine has obvious advantages of labor saving, material saving and time saving compared with the traditional prefabrication process, and the cost is saved by about 25%-35%.
Technological Advantage:
As the kerb machine is directly in the field slipping mold forming kerb, and can be embedded in the ground as the foundation.Therefore, the formed kerb is not only linear and beautiful appearance, but also has a high impact strength and stability, and its overall strength and stability is incomparable with the traditional kerb prefabrication technology. In the traditional prefabrication process of producing kerb, because of the site installation process, kerb can only be simply filled and beautified between each other, and the soil change of different foundation, the change of pressure inside and outside the road and other factors make kerb will become stagger without affected by external forces, directly affecting the appearance.If it get hit, the consequences are even worse.
In a word, the advantages of kerb machine are high efficiency, beautiful appearance, low cost and high quality.
Shotcrete machine, is a new type and high efficiency spraying machinery, mainly suitable for the section concrete spraying operation of section. It has reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and long service life. Dust-free, low noise and low resilient rate when working.
The working principle of spraying machineï¼?
The equipment uses a rotor pump to deliver the concrete to the nozzle through the pipeline, and the concrete is sprayed to the wall of the sprayed tunnel by the compressed air along with the accelerator agent.
Application:
1.Widely used in engineering construction, mines, tunnels, culverts, subway, hydropower projects, underground projects and coal bog mine roadway shotcrete construction operations.
2.Spray molding or repair of refractory materials for all kinds of industrial furnaces and kilns and lining.
3.Soil transportation and spraying during all kinds of slope protection and greening construction.
4.This machine can be used for wet spraying, dry spraying and all kinds of fiber spraying.
