Setting is arranged successively in cross-sectional direction, and railway bed land used range 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, reaches railway bed by town dweller area land used most
It is small, meet the requirements such as environmental protection, investment reduction, and structure has feature safe and reliable, easy for construction.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high speed railway sound barrier, contact net and cutting supporting and retaining systems
Trinity structure, to solve, the land used range that high-speed railway is faced close to town dweller area is limited, noise control is stringent, engineering
The technical barriers such as investment saving.
The technical solution that the utility model solves used by above-mentioned technology is as follows：
The high speed railway sound barrier, contact net and cutting supporting and retaining system Trinity structure of the utility model, including it is set to height
Sound barrier, catenary mast between fast railway cutting and residential block, it is characterized in that：The sound barrier, which is that section is L-shaped, to be hanged
Arm-type sound barrier retaining wall has the cantilever erect and extends into the bottom plate in high-speed railway cutting；The madial wall of the cantilever
Bracket is arranged in upper edge circuit extending direction interval, and catenary mast is set on bracket；The cantilevered sound barrier retaining wall
Outside setting backfill layer.
The utility model has the beneficial effects that cantilevered sound barrier retaining wall can not only be used for the branch of high-speed railway cutting engineering
Structure is kept off, faces hovering arm and can be used as the sound barrier close to town dweller area, setting bracket can be used for placing by cutting engineering side
Catenary mast.The structure can effectively solve the problem that high-speed railway close to town dweller area reduction noise, save the area, reduce throwing
The serial problem such as money, at home and abroad high-speed railway field still belong to the first time propositions, have structure novel, securely and reliably, construction is simple,
The features such as meeting environmental protection.

Specific implementation mode
The utility model is further illustrated below by specific embodiment and in conjunction with attached drawing.
With reference to figure 1, the utility model high speed railway sound barrier, contact net and cutting supporting and retaining system Trinity structure, including set
Sound barrier, the catenary mast 3 being placed between high-speed railway cutting F and residential block J.The sound barrier, which is that section is L-shaped, to be hanged
Arm-type 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
Bracket 2 is arranged in 1.1 madial wall upper edge circuit extending direction interval, and catenary mast 3 is set on bracket 2.The cantilevered
The outside setting backfill layer 4 of sound barrier retaining wall 1.Cantilevered sound barrier retaining wall 1 can not only be used for the supporting and retaining system of high-speed railway cutting F
Structure faces empty cantilever 1.1 and can be used as the sound barrier close to residential block J, and by the sides high-speed railway cutting F, setting bracket 2 can be used
In placing catenary mast 3, effectively solve high-speed railway close to town dweller area reduction noise, save the area, reduce investment
Deng serial problem,
With reference to figure 1, antiskid key 1.4 is set, 1.2 or less bottom plate is screed-coat 6 and blotter 7 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
The pvc pipe of diameter 80mm usually may be used in drain hole 1.3, drain hole 1.3, is embedded in 1.1 bottom of cantilever, drainage grade is not
