Machine train consisting of a road milling machine and a paver and method for operating a road milling machine and a paver

Abstract: The invention relates to a machine train composed of a road milling machine 1 that travels in front and comprises a machine frame 3 supported by crawler tracks 3, 4 or wheels and a milling drum 10 arranged on the machine frame that is for milling away material, and to a road finisher 16 that travels behind and comprises a machine frame 18 which is supported by crawler tracks 17 or wheels and on which a reservoir 19 for material to be laid and a screed 20 for laying material are arranged. The invention also relates to a method for operating a machine train composed of a road milling machine travelling in front and a road finisher travelling behind. The machine train composed of the road milling machine and the road finisher is characterized in that the road milling machine 1 has a profile data determining device 33, wherein the profile data determining device 33 is configured so that a sequence of height profile data describing the height of the road surface in the longitudinal direction is determined while the road milling machine advances. For transmission of the height profile data, a data transmission device 27 is provided on the road milling machine 1 and a data receiving device 27 is provided on the road finisher 16. To change the position of the screed 20, the road finisher 1 has a levelling device 23 that comprises at least one actuator 24 and a controller 23A, which is configured so that the controller 23A generates a control signal for controlling the at least one actuator 24 in accordance with a height profile data set.

Bearing platform waterscape

Abstract: The utility model discloses a bearing platform waterscape. The bearing platform waterscape comprises stainless steel sheets, a pool facing stone material (2), a stainless steel framework (3), a stainless steel structure (5), a concrete pool wall (12) and a concrete floor slab (13), wherein a broken stone hardcore (11) and a concrete screed (10) are sequentially paved on the concrete floor slab (13); the stainless steel structure (5) is mounted at the inner side of the concrete pool wall (12), fixed on the concrete screed (10) and connected through an embedded part; the stainless steel sheets are paved on the surfaces of the concrete screed (10), the stainless steel structure (5) and the concrete pool wall (12), and are welded to form a stainless stele liner (4). The bearing platform waterscape solves the problems of leakage, difficult repair after leakage and the like in traditional waterproof work of the water pool; besides, the late maintenance cost of the water pool is reduced, and potential hazards such as water leakage, water seepage and the like of the indoor water pool are fundamentally eliminated.

Basement roof drainage system

Abstract: The utility model discloses a basement roof drainage system aims at providing the drainage system that a concentrated infiltration rainwater carries out the drainage, is applicable to the underground garage, and its technical scheme main points are, including the green vegetable layer, planting soil layer, the filter layer that set gradually, hold the drainage blanket, hinder root layer, roof basic unit, hinder and be equipped with one between root layer and the roof basic unit and look for slope layer and a screed -coat, screed -coat around in looking for slope layer outer lane and be in the edge of roof basic unit, the surface of roof basic unit is equipped with a plurality of catch water drains, the side of roof basic unit is equipped with the outer discharge mouth of a river with the screed -coat intercommunication, discharge the outward mouth of a river and catch water drain feed through Through roof basic unit be equipped with a plurality of catch water drains on the surface, in rainwater infiltration trickling to the ditch of catchmenting, through the catch water drain water conservancy diversion mouth of a river of discharging outside to, the mouth of a river of discharging has outward made things convenient for the discharge of the rainwater of the ground storehouse top surface of large tracts of land, the environmental protection is durable, clean environment

Apparatus for producing flowing screed

Abstract: A mixing machine which can be filled with ready-made dry mortar from a silo via a conveying means has a mixing container on which a water-metering means is connected and which is equipped with a level indicator which, when a predetermined level has been reached, stops the conveying means which supplies the ready-made dry mortar As a result, even when the supply of ready-made dry mortar is not constant with respect to time and without complex weighing, the water/ready-made dry mortar value, which is decisive for the quality of the flowing screed, remains constant with a very low tolerance

Triode screeding machine knife tool apparatus

Abstract: The utility model discloses a blade device for triode screed machine, comprising a lower mould, an upper mould engaged with the lower mould, and a dump plate hung on the upper mould. The lower mould is provided with a big guiding pillar, and the upper mould is provided with a big cover matched with the big pillar while the big pillar is through in the big cover. The upper mould is fixed with a small guiding pillar crossing the dump plate, while the lower mould is provided with a small guiding cover matched with the small pillar. The upper surface of the lower mould is concave to form a material guiding slot with bottom provided with a supporting block. And the bottom side of the material guiding slot is provided with a screed lower blade, crossing the supporting block, which is composed of a group of separated screed knives. The upper mould is provided with an upper blade fixing base which is provided with a screed upper blade engaged with the screed lower blade while the screed upper blade is composed of a group of separated screed knives. The utility model has the advantages in low using cost, accurate match between the upper and lower moulds and accurate locating of triode bar.
