(1) The purpose of the chisel: The chisel is used for the waterproof treatment of the deck surface. The automatic walk of the two-lined side wall arc surface of the tunnel for the tunnel's low edge wall can be automatically walked. The convenience of moving the machine not only reduces the labor cost, but also has a uniform and beautiful effect. Received the unanimous praise and approval of the Iron Tunnel Engineering Bureau.
In order to treat the interface clean float, increase the contact surface, exposed stone material can be closely combined. The first is pretreatment. Before the second liner is in place, the contact surface between the low side wall and the bottom of the platform is processed to ensure that the seams are tight after being in place; The second is to deal with it afterwards. If the second liner finds the wrong platform and affects the appearance, it will be handled immediately after demoulding. If the wrong platform is within 5cm, the direct grinding wheel will be polished to make it smooth and excessive. If the wrong platform is greater than 5cm, It must be chiseled and removed. Then use white cement and ordinary cement to mix, ensure that the blending color is consistent with the original color of the concrete, and then apply the deployed cement mud to the chisel surface to ensure that the surface is smooth, and if the surface is large, it can be maintained after adding a template.
Pneumatic hair-chiseling machine is used for the waterproof treatment of the beam surface of high-speed railway box girder(prefabricated girder).
The concrete chisel is used for the concrete chisel on the side of the bridge, the end of the bridge, the side of the beam, and the end of the beam.
The road surface chisel is used to remove ground coating, paint, and various traffic marks.
Pneumatic hair-cutting machines are used to clean and clear airport road markings, tire braking marks on aircraft runways, etc., and to regain rough surfaces with high friction coefficients.
Small hair-chiseling machine is used for surface treatment of cement asphalt pavement, highway deck, bridge wrong platform, epoxy resin wear-resistant ground, etc..
Hand-held hair-chiseling machine is used for the construction of road micrometers, and the original old road surface layer is removed to prepare for the slurry sealing layer.
The new technology of the machine is a four-edged chisel and a high-sealing sealing sealing device designed for high-speed railways and highway C50 concrete. This product is also widely used in the ground floor treatment before the renovation of various old ground, removing epoxy resin from damaged ground raised parts, doing Anti-Slip surface, blind track and new surface coating. It fully reflects the low cost and high efficiency of the application value, and has the characteristics of beautiful appearance, stable performance, flexible operation, convenient handling and so on. Since many of the current hair-cutting machinery products will not only destroy the protective layer of reinforced concrete, but also cause damage or even catastrophic damage to the original structure, it is now in many projects, especially bridges and tunnels.
Let the concrete bond firmly. According to the construction process, chisel hair is divided into: all chisel hair and star-point chisel hair. In simple terms, artificial hair cutting is to turn smooth concrete surfaces into rough wool surfaces, easy to rub surfaces in the future, and the machine has a concrete hair-cutting machine. The machine can operate freely on the ground surface, three-dimensional walls, and concrete surfaces of various arc surfaces. It is used in traditional artificial chiseling, wind picks, Milling and planing, sandblasting, flushing, and pre-drawing have achieved a revolutionary leap. Chisel is when the tile or powder is affixed after the road is built. In order to make the concrete surface more firmly paste, the concrete surface is cut to the surface according to the need, the thickness of the hair is 5 to 10 mm, and the spacing of the chisel hair marks is about 30 mm. The cut hair rate is not less than 90 %. After that, clear ash, mortar, oil stains and so on. 2, so far there is no national standard specific regulations, but chiseling hair has a regulation on the strength of the bristle, generally when the bristle is artificially chiseled, the strength of the bristle must reach 2.5 N/mm2, and when the wind engine is used to chisel hair, it must reach 10N/mm2. Water should also be added to keep the concrete moist until new concrete is poured.
