Abstract

The utility model discloses a plum blossom hole aqueduct specially used for the roadbeds, which is combined together by a soft layer (5), a firm layer (6) and a hard layer (7). The aqueduct is provided with a plum blossom hole (3) or a Chinese character <zhi> shape hole (4) which is communicated with an opening (2) of the aqueduct, can transmit the water and cooperate with the construction of the railway and the road, is laid on a yellow sand layer (9) under a road layer (8). Groundwater (13) in the roadbed can permeate into the plum blossom hole (3) or the <zhi> shape hole (4), and flows out through the opening (2) of the aqueduct so that the roadbeds of the railway and the road are protected from being soaked by the up returning groundwater.

Description

Special aqueduct with plum blossom hole for road base

Affiliated field

The utility model relates to the aqueduct that is adopted in railway, the highway subgrade flood Prevention Technique, especially by the synthetic special aqueduct with plum blossom hole for road base of the outer soft three layer construction of interior hard backbone.

Background technology

The technology of controlling of returning to stations on known railway, the highway underground water to be adopted and adds elevated formation level, deep-cuts gutter, buries the way of thick pipe of cement or metal tube underground, alleviate or prevent and treat on the underground water and return with this, wherein pipe of cement that is adopted or metal tube, single, thick, can only solve on the water conservancy diversion of a large amount of rainwater and the local paroxysmal underground water and return problem, for returning problem on the long-term property of low-lying region underground water, never have the technical scheme of radical cure.

Summary of the invention

The purpose of this utility model provides a kind of special aqueduct with plum blossom hole for road base of preventing and treating railway, highway water damage, when cooperating railway, highway construction, be layed under the supercrust, in the sandstone on the base course, the plum blossom hole that can be effectively gathers by aqueduct or the word hole, with on the underground water water conservancy diversion that returns in the roadbed gutter.

For achieving the above object, roadbed special aqueduct with plum blossom hole of the present utility model is by interior hard formation (as duroplasts), backbone layer (as aluminium alloys or stainless steel), outer soft formation (as flexible plastic or rubber) be combined into; The aqueduct body be provided with the preface plum blossom hole or the word hole, plum blossom hole or the word hole all communicate with conduit mouth; Special aqueduct with plum blossom hole for road base with equidistantly be layed under the supercrust, in the sandstone on the base course, can with the underground water that returns in the roadbed through gathering plum blossom hole or word hole water conservancy diversion in gutter.

Adopt such technical pattern, in railway, highway construction, can effect a radical cure effectively on the roadbed underground water and return problem, can prolong the application life of railway, highway, reduce the construction cost of railway, highway.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment

Special aqueduct with plum blossom hole for road base shown in Figure 1 is formed oval tubulose by aqueduct 1 and two conduit mouth 2, and is smooth unimpeded in the tube chamber.

Special aqueduct with plum blossom hole for road base shown in Figure 2 is established plum blossom hole 3 by aqueduct 1, and plum blossom hole 3 communicates with conduit mouth 2.

The word hole 4 that special aqueduct with plum blossom hole for road base shown in Figure 3 is established by aqueduct 1, word hole 4 communicate with conduit mouth 2.

Special aqueduct with plum blossom hole for road base cross section shown in Figure 4 is by outer soft formation 5, backbone layer 6, interior hard formation 7 be combined intos, but conduit mouth 2 water flowings.

Special aqueduct with plum blossom hole for road base shown in Figure 5 is embedded in the yellow sand layer 9, yellow sand layer 9 upper strata are that supercrust 8, lower floor are macadam 10, block stone layer 11 and soil matrix layer 12, and contained underground water 13 infiltrates plum blossom hole 3, flows out from conduit mouth 2 through tube chamber through yellow sand layer 9 in the roadbed.

During use, can be according to returning situation on railway, the highway section underground water, the unrestrained or close special aqueduct with plum blossom hole for road base of putting; During making, its materials, thickness, the density in hole and size can conversion to put into practice role, and these conversion all drop within the protection domain of the present utility model.
