Expansion and contraction device and the application modulo for guttation of high level road

摘要

Abstract Topic The seal stop the rainwater which flows into from the connection of the high level roadThe zu, accepting this, to intersection direction of the road the guttation Characteristic which is dischargedThe expansion and contraction device which is rich in talent is offered. SolutionsDestal coupling (B) and unit coupling (A) and soThe adjustable coupling which to between mutual the mediating/helping Interpolation is used (C) at a time 1 tuppleIt forms both standing up hueisupureto (11a) which (11b)(The mutual gap (G1) where (G2) 11c) faces (G3) to, water permeability kutsu which becomes the one for invasion solid-state thing capture from hereShaun filter (18a) (18b) (18c) eachAs restoration in Various compressed state, that filter is transmitted,It is the expansion and contraction possible water catchment discharge belt which becomes the one for acceptance of the rainwater(23), the above-mentioned coupling (A) (B) (C) entire lengthTo (the long shaku which reaches L5) as 1 ones, the both standing up hueiIt hung to the bottom of supureto and installed in state.
