Detailed description of the invention
Carry out clear complete description below with reference to the technical scheme of accompanying drawing to each embodiment of the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not needing creative work, all in the scope that the utility model is protected.
Consider that current embankment props up gear flood level higher than curb, and the problem of structure limit for width, present embodiments provide the U-shaped retaining structure of a kind of embankment formula.
The U-shaped retaining structure of a kind of embankment formula is " U " type groove structure, and its cross section is in " U " type; The width of the bottom of " U " type groove structure is more than or equal to minimum vehicle pass-through gauge width; The height of the Liang Ge branch sidewall of " U " type groove structure is more than or equal to the century-old flood level of design.
Adopt " U " type groove structure, width bottom it is more than or equal to minimum vehicle pass-through gauge width, the height of Liang Ge branch sidewall is more than or equal to the century-old flood level of design, solve Traditional foundations embankment section design flood level higher than roadbed curb design altitude, and be subject to the problem of the control of existing building limit for width limit for height, both realize waterproof, meet again the requirement of limited gear.
The multiple embodiment of following utilization is described in detail:
The U-shaped retaining structure of a kind of embankment formula, as Fig. 1, shown in 2, is " U " type groove structure, is in above-ground route more than 4, comprise Liang Ge sidewall branch 2 and bottom 1, in groove, and laying bedding and track 6 or paving on bottom 1, and ancillary service.
That is, this retaining structure is along road bearing of trend longitudinal extension, and its cross section is in " U " type, and the cross section namely perpendicular to road bearing of trend is " U " type for " U " type groove structure.In order to solve the problem of existing flood level higher than curb, and the problem of structure limit for width, the width of the bottom 1 of " U " type groove structure is more than or equal to minimum vehicle pass-through gauge width, and at present, minimum vehicle pass-through gauge width is generally between 8.2-8.88 rice; The height of Liang Ge sidewall branch 2 sidewall of " U " type groove structure is more than or equal to the century-old flood level of design, and at present, Sidewall Height adds 0.7 meter again by the century-old flood level of design.
Consider and meet the requirement that maintenance personal security keeps away car function, along road bearing of trend, Liang Ge sidewall branch 2 sidewall of " U " type groove structure is respectively to the multiple refuge chamber 3 of external expansion.Maintenance personnel can return in refuge chamber 3 through out-of-date at vehicle.The width of refuge chamber is 2-4 rice, and hole is 1-2.5 rice deeply.Such as: large refuge chamber is wide × be deeply 4 × 2.5 meters, little refuge chamber wide × be deeply 2 × 1 meters.
Need to arrange multiple refuge chamber 3 at roadside, to adapt to the needs of different location maintenance personnel, therefore, the distribution mode presetting refuge chamber 3 is abnormal important.In practical operation, refuge chamber 3 is by predetermined manner distribution.This predetermined manner can be that refuge chamber 3 distributes with same distance, or distributes with the situation compliance in railway location, and such as condition is complicated, and the local refuge chamber 3 many through vehicle is densely distributed, and other situation refuge chamber 3 tamped density are little.More specifically distribution mode is: refuge chamber is by 30 meters of spacing both sides interlaced arrangement, refuge chamber is arranged: the large refuge chamber of the little refuge chamber+1 of 1 large refuge chamber+4+... .., namely to be crisscross arranged large refuge chamber every 150m both sides, all the other every 30m both sides are crisscross arranged little refuge chamber.
More intimate in order to what set up by " U " type groove structure, more practical, superstructure arranges rain-proof shed.To reduce groove internal water accumulation, ensure traffic safety, convenient construction personnel, maintenance personnel wind sheltering wherein is simultaneously kept off the rain.
The size of refuge chamber 3 can set according to actual conditions, usually can be: the width of refuge chamber 3 is 2-4 rice, and hole is 1-2.5 rice deeply.Large refuge chamber is wide × be deeply 4 × 2.5 meters, and little refuge chamber is wide × be deeply 2 × 1 meters.
In order to strengthen the intensity of supporting and protection structure, " U " type groove structure is built up by steel concrete, and this structure is reinforced concrete structure.
In order to meet ground requirement for bearing capacity, structure bottom is protected effectively, and meet the requirement of green channel construction, therefore, outside the bottom 1 of Liang Ge sidewall branch 2 sidewall of " U " type groove structure, banket 5.
The on-the-spot framework mode of the U-shaped retaining structure of this embankment formula is:
Step 101, excavation pit, processes ground on request, meets ground requirement for bearing capacity.
Step 102, formwork erection ties up reinforcing bar, installs built-in fitting, controls width by minimum vehicle pass-through gauge requirement, controls height of side wall by the century-old flood level of design, and cast-in-situ concrete is to form the U-type groove structure of band refuge chamber.Can arrange that awning is rainproof, wind sheltering if desired above U-type groove.
Step 103, by setting earth filling tamping outside U-type groove, plant landscape.
Step 104, lay bedding and track or paving in groove, and ancillary service is installed.
The U-type groove structure of the embankment formula band refuge chamber that the utility model provides, namely solves the problem of flood level higher than curb, solves again the problem of structure limit for width; Meanwhile, groove suitably bankets outward, namely plays certain protective role to structure bottom, meets again green channel construction requirements, embodies environmental friendliness theory.The U-type groove structure applicability of utility model is strong, and more current general structure form reduced investment, has obvious economic results in society.
The various embodiments that the utility model provides can combine as required in any way mutually, the technical scheme obtained by this combination, also in scope of the present utility model.
Obviously, when not departing from spirit and scope of the present utility model, those skilled in the art can carry out various change and modification to the utility model.If to change of the present utility model these and modification is within the scope of claim of the present utility model and equivalent thereof, then the utility model also will comprise these and change and modification.
