Abstract
The utility model discloses an underneath pass interchange approach road structure and aims to design the underneath pass interchange approach road structure with reasonable structure and lower maintenance cost. The technical scheme adopted by the utility model is as follows: the underneath pass interchange approach road structure comprises an underneath pass interchange approach road body, wherein a U-shaped concrete groove is formed in the part, passing through and below a railway, of the underneath pass interchange approach road body; L-shaped grooves are formed in the two sides of the U-shaped concrete groove. The underneath pass interchange approach road structure has a reasonable structure and an excellent using effect and can ensure the road quality and the service life of an underneath pass interchange approach road in the construction environment with shallower underground water.
Description
Technical field:
Under the utility model relates to, wear grade separation and lead the way, particularly a kind of result of use good under wear the grade separation structure of leading the way.
Background technology:
In urban construction, when major urban arterial highway and railway cross, road need to be crossed over to railway, in construction, one conventional of mode is to set up overpass bridge to cross over railway, another mode is set up underpass road exactly, from railway below, pass through, and the structure in underpass road is generally to adopt to dig under road surface, from railway below, pass through, support is set up in position below road railroad crossing, guarantee the safety of railway and the safety in underpass road, but the underpass road of this structure is when running into the more shallow construction environment of groundwater table, just inapplicable, underground water can make the roadbed long period of soaking in underpass road in water, cause the road surface in underpass road compared with cracky, maintenance cost is high, be unfavorable for safeguarding the normal use of urban traffic.
Summary of the invention:
The purpose of this utility model is that design is a kind of rational in infrastructure, maintenance cost lower under wear the grade separation structure of leading the way.
The technical solution of the utility model is, wears the grade separation structure of leading the way under a kind of, and it wears the grade separation body of leading the way under comprising, it is characterized in that: under wear the grade separation part below railroad crossing in body of leading the way and set up U-shaped concrete pit.Describedly in U-shaped concrete pit both sides, be provided with L shaped groove.
The utility model is rational in infrastructure, and result of use is good, can, under the more shallow construction environment of underground water, wear road quality and application life that grade separation is led the way under assurance.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail, under a kind of, wear the grade separation structure of leading the way, it wears the grade separation body 2 of leading the way under comprising, under wear the grade separation part below railroad crossing in body of leading the way and set up U-shaped concrete pit 3, being convenient to vehicle passes through, because U-shaped concrete pit is waterproof effectively, can make roadbed not by groundwater erosion, and be provided with L shaped groove 1 in described U-shaped concrete pit both sides, be convenient to pedestrian and bicycle passes through, L shaped groove also adopts concrete material simultaneously, can play protection against the tide simultaneously, the effect of waterproof, under being conducive to, wear the application life that grade separation is led the way, road quality is guaranteed, need not be regular road be keeped in repair, guaranteed the smooth traffic in city.
Claims (2)
1. under, wear the grade separation structure of leading the way, it wears the grade separation body of leading the way under comprising, it is characterized in that: under wear the grade separation part below railroad crossing in body of leading the way and set up U-shaped concrete pit.
2. the grade separation structure of leading the way of wearing under a kind of as claimed in claim 1, is characterized in that: describedly in U-shaped concrete pit both sides, be provided with L shaped groove.
