Abstract

The invention relates to a tunnel ditch insulation structure. In a traditional tunnel drainage ditch, a double-layer cover plate insulation ditch is commonly used, insulation materials are added in the middle of the double-layer cover plate insulation ditch, the mode that angle steel is embedded on the side wall of the ditch and a cover plate is placed on the angle steel is used for mounting the second cover plate layer, construction difficulty is large, the cover plate can fall easily to plug the ditch for the reasons of breakages, size errors and the like, and water draining is not smooth. According to the tunnel ditch insulation structure, a reinforcing steel bar support with a U-shaped cross section is arranged above a ditch in a tunnel, the bottom face of the reinforcing steel bar support is higher than the water surface in the ditch, and the reinforcing steel bar support is filled with insulation materials. The top edge of the reinforcing steel bar support is bent to the two sides in the horizontal direction and is placed in ditch wall surface chisel grooves formed in the two sides of the top of the ditch, cement mortar is used for flattening the ditch wall surface chisel grooves, and a ditch cover plate covers the reinforcing steel bar support. The tunnel ditch insulation structure can achieve the insulation purpose of tunnel ditches in cold regions, and has the advantages of being simple in construction, convenient to replace, saving in investment and the like.

Description

Tunnel ditch insulation construction
Technical field
the invention belongs to tunnel traffic field of engineering technology, be specifically related to a kind of tunnel ditch insulation construction.
Background technology
China in northwest, Deng Han district, northeast built a large amount of construction of tunnel, two ends, tunnel in winter Portal Section temperature is lower, in cold, (the coldest monthly mean temperature is higher than-10 ℃, but lower than-3 ℃) and severe cold (the coldest monthly mean temperature is lower than-10 ℃) area, be easy to cause water freezing in gutter, and spread to ditch gradually, and then jeopardize traffic safety.How to adopt an effective measure, guarantee that tunnel internal drainage does not freeze to discharge smoothly, guarantee that traffic safety is to make technician pay close attention to and the problem of headache thereby avoid producing disease always.Traditional tunnel drainage ditch generally adopts double-layer cover plate heat preservation ditch, the middle heat insulating material that adds, the employing of installing of second layer cover plate is placed in the mode on angle steel at the pre-buried angle steel of ditch sidewall, cover plate, difficulty of construction is large, cover plate, due to reasons such as breakage, scale errors, is easy to drop and stops up ditch, causes impeded drainage, water in ditch is more easily frozen, and form disease.
Summary of the invention
The object of this invention is to provide a kind of tunnel ditch insulation construction of safer, better heat preservation.
The technical solution adopted in the present invention is:
Tunnel ditch insulation construction, is characterized in that:
Top, ditch in tunnel arranges the Steel bar rack that cross section is U-shaped, and Steel bar rack bottom surface, higher than water surface elevation in ditch, is filled with heat insulating material in Steel bar rack;
Steel bar rack apical margin bends to both lateral sides, is placed in the ditch wall surface raggle that both sides, top, ditch arrange, and adopts cement mortar floating, and ditch cover plate is put up in top.
Steel bar rack is to be intersected and pricked the network that side forms by reinforcing bar, and segmentation prefabricating, arranges along ditch longitudinal separation.
Heat insulating material is polyurethane thermal insulation board or cystosepiment, multilayer segmentation prefabricating, and every joint longitudinal length is greater than the longitudinal pitch of Steel bar rack, and single-unit heat insulating material is placed on two longitudinally adjacent joint Steel bar racks.
The present invention has the following advantages:
Fabrication and installation of the present invention are convenient, reinforcing bar is bent into definite shape, ditch sidewall raggle, settle at a certain distance Steel bar rack, on it, place again the chemical such as rectangle, strip heat insulating material, thereby reach the object of tunnel in cold area ditch insulation, there is the plurality of advantages such as construction is simple, replacing is convenient, investment saving.
Accompanying drawing explanation
Fig. 1 is cross section of the present invention.
Fig. 2 is Steel bar rack figure of the present invention.
In figure, the raggle of 1-ditch wall surface, 2-Steel bar rack, 3-heat insulating material, 4-ditch cover plate, 5-cable channel, 7-ditch.
The specific embodiment
Below in conjunction with the specific embodiment, the present invention will be described in detail.
A kind of tunnel ditch insulation construction the present invention relates to, longitudinally arranges along ditch, and 6 tops, ditch in tunnel arrange the Steel bar rack 2 that cross section is U-shaped, and Steel bar rack 2 bottom surfaces, higher than the interior water surface elevation in ditch 6, are filled with heat insulating material 3 in Steel bar rack 2.Steel bar rack 2 apical margins bend to both lateral sides, be placed in the ditch wall surface raggle 1 that 6 both sides, top, ditch arrange, employing cement mortar is floating, ditch cover plate 4 is put up in top, form a kind of form that arranges at tunnel in cold area heat preservation ditch, on the basis of improving difficulty of construction, reach the effect that does not affect insulation.
Steel bar rack 2 is to be intersected and pricked the network that side forms by reinforcing bar, and segmentation prefabricating, along ditch 6 longitudinal separation settings.Heat insulating material 3 is polyurethane thermal insulation board or cystosepiment, multilayer segmentation prefabricating, and every joint longitudinal length is greater than the longitudinal pitch of Steel bar rack 2, and single-unit heat insulating material 3 is placed on two longitudinally adjacent joint Steel bar racks 2.
It is cited that content of the present invention is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading manual of the present invention, is claim of the present invention and contains.
