Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, gutter comprises base plate 1, sidewall 2 and cover plate 3, described gutter is rectangular drain ditch, the present invention is designed to the flase floor of each 40 ~ 60mm of actual situation gutter base plate 1, gutter can not establish cover plate or cover plate to be also designed to the flase floor of each 40 ~ 60mm of actual situation, lays the hardcore bed 4 of the thick diameter 40 ~ 60mm of 80 ~ 120mm, lay one deck 400g/m under bed course bottom the base plate of gutter
2non-woven geotextile 5.In figure, dotted line is excavating sideline, after described gutter having been placed after excavation, and filling backfill 6 around described gutter.According to a preferred embodiment of the invention, gutter back-plane design becomes the flase floor of each 50mm of actual situation.Bar shaped concrete grating just in time can place reinforcing bar, and transmit soil at both sides pressure, meet structural safety requirement, grid is spaced apart 50mm bar hole, meets rainwater infiltration, naturally grows little grass after meeting certain hour.Owing to being provided with 100mm hardcore bed bottom the base plate of gutter, and at its lower laying one deck non-woven geotextile, therefore after certain hour, naturally can grow little grass, and shrub can not be grown, reduce manual maintenance time and cost.This engineering need strengthen No. 1 by transverse reinforcement in the way of municipal administration general gutter, and longitudinal reinforcement remains unchanged, and actual situation spacing is all 50mm simultaneously, is convenient to model customization and construction.
As shown in Figure 3 and Figure 4, described gutter is trapezoidal gutter, sidewall due to this gutter is what tilt, in order to can rainwater infiltration be made, also the flase floor 7 of each 40 ~ 60mm of actual situation is provided with in the sidewall in this gutter, at the arranged outside hardcore bed 4 of gutter sidewall, hardcore bed thickness is 80 ~ 120mm, lays one deck non-woven geotextile 5 outside bed course.Surrounding's filling backfill 6 in described gutter.
