Upper reaches of the drainage ditch near the sidewalk excavation, lowering the water level elevation, in order to prevent rainwater and other water flows into the stent area, causing stent sink. bracket arrangement Scaffold Specifications Frame by frame button steel bowl, pole mainly , , species, a long pole then staggered arrangement, plunger length , , , bar with , ponents, top and bottom with adjustable prop support care. support arrangement Box under the pole vertical distance , horizontal distance , horizontal and vertical bar step , and set the scissors truss reinforcement. Stent Xiadian 15 15cm sleepers, pole adjustable pedestal support base located in the sleeper, the pole on the set adjusted backwater, backwater above the laying of 15 15cm square wooden horizontal, vertical laying of 10 10cm square of wood. Stand for the shape of Bowl bracket, first determine the initial installation, the installation location, and according to the starting height of the ground level to determine pole placement Sleepers, the use of adjustable elevation of the leveling will be the end of care, to avoid local grievances led to uneven vacant or under Poleuneven, the installation can be installed to take the first measurement of the ground segment elevation, according to the measured data to calculate the pole bottom level, first with the adjustable bottom bracket standard will be four corner pole hang after installation of highprofile flat other end of care, aftervertical mounting rails. Notes stand arrangement (1) When the pole is greater than 60cm height difference between the base, then the pole can be used to adjust the wrong section. (2) take a long pole in the joints should be staggered, the first layer of and with long pole in the pole staggered arrangement, and both up the pole with , and to the top and thenm length of the mandrel two leveling. (3) the degree of vertical pole should be strictly controlled: 15m shelf press the following 1 / 200 control, and the full height of the vertical deviation should be less than 10cm. (4) scaffolding assembled to 3 to 5 storeys, the horizontal bar with a theodolite check the verticality of the degree and the case of no load polebycheck for loose or empty floating base, and to tighten the adjustable seat and promptly adjust the pad Sheet implemented. (5) braced grid should adapt with the size of the brace for the pull bar, layout direction can be normal circumstances bracing should be connected to the node with the scaffolding, but also the wrong section layout. (6) diagonal brace layout density, when the scaffold height of less than 20m, in order to frame the whole area of 1 / 2 to 1 / 4, diagonal brace must be symmetrically arranged, and should be evenly brace for strengthening the overall scaffold stiffness and load capacity in it should not be arbitrarily removed. support After laying support, the need for prepress, to test the strength and foundation support and stability, to eliminate the plastic deformation of the entire frame, eliminating the foundation of the settlement, the elastic deformation measured stent.
