Description
Technical field
The present invention relates to high-speed railway subgrade technical field, more particularly to sound barrier, contact net and cutting supporting and retaining system three one
Body structure.
Technical background
The noise control requirement in high-speed railway close to town dweller area is stringent, and face downtown areas railway land be limited,
Working space is narrow to wait serial problem, particularly shallow cut cutting engineering.In this regard, if high-speed railway is with bridge or Tunnel Engineering
By town dweller area, line position need to be raised or be reduced to railway, easily cause along construction investment be significantly increased；If led to roadbed
Cross, since railway needs close to town dweller side to set the structures such as sound barrier, contact net and subgrade support retainer, if by these structures
Setting is arranged successively in cross-sectional direction, and railway bed land used scope will be caused to significantly increase.To solve above-mentioned problem, there is an urgent need for carry
Go out a kind of collection sound barrier, contact net and cutting supporting and retaining system Trinity structure, reach railway bed by town dweller area land used most
It is small, meet the requirement such as environmental protection, investment reduction, and structure has feature safe and reliable, easy for construction.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high speed railway sound barrier, contact net and cutting supporting and retaining system three
Integrative-structure, is limited, noise control is stringent, construction investment with solving high-speed railway close to the land used scope that town dweller area faces
The technical barriers such as saving.
Technical solution used by the present invention solves above-mentioned technology is as follows：
High speed railway sound barrier, contact net and the cutting supporting and retaining system Trinity structure of the present invention, including it is arranged at high-speed iron
Sound barrier, catenary mast between road cutting and residential block, it is characterized in that：The sound barrier is the L-shaped cantilevered of section
Sound barrier retaining wall, has the cantilever erect and extends into the bottom plate in high-speed railway cutting；Edge on the madial wall of the cantilever
Circuit extending direction is arranged at intervals bracket, and catenary mast is arranged on bracket；The outside of the cantilevered sound barrier retaining wall
Backfill layer is set.
The invention has the advantages that cantilevered sound barrier retaining wall can not only be used for the supporting and retaining system knot of high-speed railway cutting engineering
Structure, it, which faces hovering arm, to set bracket to can be used for placing contact by cutting engineering side as the sound barrier close to town dweller area
Net pillar.The structure can effectively solve the problem that high-speed railway close to town dweller area reduction noise, save the area, reduce investment etc.
Serial problem, at home and abroad high-speed railway field still belong to the first time proposition, there is novel structure, safe and reliable, construction is simple, meet
The features such as environmentally friendly.
Brief description of the drawings
Fig. 1 is the profile of high speed railway sound barrier of the present invention, contact net and cutting supporting and retaining system Trinity structure；
Main member title and corresponding mark are shown in figure：Cantilevered sound barrier retaining wall 1, cantilever 1.1, bottom plate
1.2nd, spilled water hole 1.3, antiskid key 1.4, bracket 2, catenary mast 3, backfill layer 4, mortar flag stone layer 4.1, sand gravel pervious bed
4.2nd, clay layer 4.3, screed-coat 6, blotter 7, loaded filter 8, high-speed railway cutting F, residential block J
Embodiment
The present invention is further illustrated below by specific embodiment and with reference to attached drawing.
With reference to figure 1, high speed railway sound barrier, contact net and cutting supporting and retaining system Trinity structure of the present invention, including be arranged at
Sound barrier, catenary mast 3 between high-speed railway cutting F and residential block J.The sound barrier is the L-shaped cantilevered of section
Sound barrier retaining wall 1, has the cantilever 1.1 erect and extends into the bottom plate 1.2 in high-speed railway cutting F.The cantilever 1.1
Madial wall ascender line road extending direction is arranged at intervals bracket 2, and catenary mast 3 is arranged on bracket 2.The cantilevered sound barrier
The outside of retaining wall 1 sets backfill layer 4.Cantilevered sound barrier retaining wall 1 can not only be used for the retaining structure of high-speed railway cutting F,
It, which faces the cantilever 1.1 of sky, to set bracket 2 to can be used for placing by high-speed railway cutting F sides as the sound barrier close to residential block J
Catenary mast 3, effectively solve high-speed railway close to town dweller area reduction noise, save the area, reduces invest etc. series
Problem,
With reference to figure 1, antiskid key 1.4 is set, and bottom plate is screed-coat 6 and blotter 7 below 1.2 on the bottom plate 1.2.It is outstanding
1.1 top width of arm is typically no less than 0.5m, should highly meet residential block J noise reduction requirements, 1.1 height of cantilever and 1.2 length ratio of bottom plate
Example should be coordinated and meet structure self stability requirement.Traverse cantilever 1.1 in the lower end edge circuit extending direction interval of cantilever 1.1
Spilled water hole 1.3, spilled water hole 1.3 can usually use the pvc pipe of diameter 80mm, be embedded in 1.1 bottom of cantilever, drainage grade is not
Less than 2%, its role is to ponding after promoting wall to discharge in time.Antiskid key 1.4 is reinforced concrete structure, whole with bottom plate 1.2
Body pours, and structure width and height are generally 0.3~0.5m, and its role is to increase the anti-slide performance of bottom plate 1.2.Screed-coat 6
Effect with blotter 7 is to ensure that cantilevered sound barrier retaining wall 1 is in close contact with ground, and plays semi-rigid~rigidity
Transitional function, top train and filled load are effectively transferred to ground.Screed-coat 6 generally uses C15~C25 plain concretes
Pour, its thickness is not less than 0.1m.7 thickness of blotter is not less than 0.3m.
With reference to figure 1, the bracket 2 is poured using armored concrete, and the longitudinal length of the bracket 2 is typically no less than
1.76m, transverse width are not less than 0.8m, its thickness should meet itself shearing resistance and bending resistance requirement, and bracket 2 is kept off with cantilevered sound barrier
Cob wall 1 uses one-piece casting.
With reference to figure 1, loaded filter 8 is set, and backfill layer 4 is by from bottom to up successively between 1.1 outer wall of cantilever and backfill layer 4
Mortar flag stone layer 4.1, sand gravel pervious bed 4.2 and the clay layer 4.3 filled is formed.
Present invention collection sound barrier, contact net and cutting supporting and retaining system form Trinity structure, reduce land used space, meet ring
Guaranteed request, structure are safe and reliable.
The above simply uses and illustrates high speed railway sound barrier, contact net and the cutting supporting and retaining system Trinity of the present invention
Some principles of structure, are not intended to the present invention being confined in shown and described concrete structure and the scope of application, therefore every
Corresponding modification and the equivalent being utilized are possible to, belongs to the apllied the scope of the claims of the present invention.
