Cement concrete pavement waterproof structure with embedded seam of full-seam-opening hollow elastic tube

Abstract

The invention discloses a cement concrete pavement waterproof structure with an embedded seam of a full-seam-opening hollow elastic tube, comprising a hollow elastic tube which is arranged in the embedded seam and can horizontally expand and contract along with the expansion and contraction of a pavement slab; the elastic tube is at least provided with an arch-shaped bulge upwards under the squeezing action of the pavement slab; the surface of the hollow elastic tube, over against the seam, is provided with an open seam of which the inside and outside are communicated; the pre-compressed magnitude of a hollow elastic waterproof part is large, so that the hollow elastic waterproof part can have relatively large extension and compression space, can adapt to deformation of a concrete slab for a long time, and especially can adapt to horizontal expansion and contraction deformation and vertical shear deformation; and when the width of a transverse seam changes with the temperature, because the compression degree of the hollow elastic waterproof part is suitable for expansion and contraction motion of the hollow elastic waterproof part, under the conditions of the expansion and contraction deformation and shear deformation of the transverse seam, by reducing the interfacial stress caused by the expansion and contraction deformation and shear deformation of the transverse seam, the joint between the transverse seam and the elastic waterproof part can not be damaged because of separation of the elastic waterproof part from the transverse seam.

Description

technical field [0001] The invention relates to a waterproof structure, in particular to a cement concrete pavement waterproof structure in which fully open hollow elastic tubes are embedded in joints. Background technique [0002] The joints of cement concrete pavement can be divided into two categories: longitudinal joints and transverse joints. Seams parallel to the center line of the course are called longitudinal seams, and seams perpendicular to the course are called transverse seams. However, when rainwater exists or flows on the pavement, the rainwater will seep from the joints of the pavement to the pavement structure, causing water accumulation or water content in the pavement structure to increase, and eventually lead to structural strength of the pavement layer, base layer, subbase layer, cushion layer, etc. On the other hand, under the dynamic and static load of the vehicle, the accumulated water or infiltrated water in the pavement structure will generate hydr...
