施工工艺的需求是什么样子的。 What is the demand for the construction technology of grass brick price ? Each brick will have a different construction process. In this aspect, various bricks are used, and then various processes are built.
Price of grass planting brick
1. The variety and quality of the plates used in various surface layers must meet the planning requirements.
2. Dalian bricks and ( pervious bricks ) should be classified according to color and pattern. Plates with cracks, corners, and defects in appearance should be removed. Plates with different labels and varieties should not be used in a turbid manner.
3. Dialing and trimming: Trim the paved bricks, pull the wire to trim the dialing seam, straighten the seam, sweep out the remaining mortar in the joint, and pat the bricks solidly. If there are broken bricks, replace them in time.
4. Arrange the size along the vertical and horizontal directions of the pavement. The width of the seam should not be greater than 5mm. When the size is less than a multiple of the entire brick, half of the brick can be cut for the corners; The gap can be adjusted, according to the confirmed number of bricks and the width of the gap, with vertical and horizontal control lines for construction and strict control of the square.
Second, the basic quality standards:
1. The surface of the various plate surfaces is clean, the pictures are clear, the color is consistent, the joints are uniform, the periphery is straight, and the plate is free of cracks, corners and chipping.
2. The slope of the ground pavement conforms to the planning requirements (and the minimum is not less than 0.3%). It does not pour water, and there is no standing water. The joint with the drainage outlet is tight and strong.
3. The size of the edging materials adjacent to the various surface layers meets the planning requirements and construction standards, and the edges and corners are regular and lubricated.
3-1, appearance flatness: controlled within 4MM, using 2M ruler to check;
3-2. Straightness of the seam: control within 3MM, check by 5M pull line, less than 5M, check through line;
3-3. Bump inspection between adjacent plates: controlled within 2MM4, corners and arc processing requirements: within;
4-1. Interface with trimming material: cut straight and straight. Regarding the cutting material at the straight seam, it is controlled by 45 °, 1 \ 4 pieces, splicing;
4-2. Arc interface processing: control the circulation of the arc, rounded, and do not allow more obvious corners, protruding phenomenon; the paving material at the interface, equal isometric cutting according to the arc length, single-sided cutting is not allowed ;
