Description
Technical field
The utility model is related to railway bed location ballastless track structure, and specifically a kind of non-fragment orbit expansion joint is close
Seal waterproof construction.
Background technology
High-speed railway or the types of Special Railway Line for Passenger Transportation location CRTS I and the III equal subsection setup of plate-type non-fragment orbit base, phase
Expansion joint is set between adjacent two sections of bases.Expansion joint be arranged along line direction, horizontal path direction, the structure with one fixed width
Make seam, it is completely separable by two sections of adjacent bases, base is done on the direction that track extends and freely stretches, prevent by
Rail bed structure is set to produce crack or destruction in temperature change.
Non-fragment orbit is in design, typically in filling elastic material (pitch plank or the cystosepiment) in expansion joint, and
Expansion joint top surface and two sides are sealed using silicone or polyurethane sealant (hereinafter referred to as fluid sealant), to avoid rainfall from passing through
Expansion joint is entered below base causes subgrade bed top layer to be risen soil in subgrade bed top layer.
Because train can produce huge shear stress when running at high speed at track expansion joints of foundation, when the shear stress is made
When using in the template or cystosepiment in expansion joint, it is easy to cause the abrasion and destruction of these materials, once this this material
Leak just occurs in damage.
In addition, after railway opens operation a period of time, because of the original such as not in place, fluid sealant aging of constructing, bedplate be flexible
Cause, also results in fluid sealant and departs from seat concrete, cause rainwater infiltration, ultimately cause subgrade bed top layer and rise soil.
Solve common structure to damage the problem of causing leak, prior art goes to solve the problem usually using two ways,
One is to go to fill expansion joint by using new material, and two be by using new structure deblocking expansion joint.
The entitled of this mode in the expansion joint such as patent No. " CN105002794A " is filled using new material " composite and to adopt
The Chinese utility model patent of the method that non-fragment orbit waterproof repairment is carried out with composite ", the patent is by using new
Composite fills expansion joint, and the utility model fills expansion joint to reach the purpose of waterproof by using four layers of composite,
Four layer materials are respectively rubber asphalt material, polyethylene polypropylene, epoxy resin and rapid hardening rubber-asphalt waterproof material, polyethylene third
Synthetic fibre can play good waterproof action as isolation layer, but the structure still has problem in intensity, in addition pitch, tree
Fat material is all the material of easy aging, the length of use time one or the problem of damage can occur again, actually again without
The problem of fundamentally solving expansion joint aging.
Entitled " the high ferro specific complex rubber of the technology such as patent No. " CN104074106A " of waterproof is carried out using new construction
The Chinese utility model patent of sealing rod ", the patent describe a kind of high ferro specific complex rubber water-proof rod, (rod is provided with recessed
Groove, and hydro-expansive rubber bar is compounded with groove power), by expansion joint internal drilling and installing fixed high ferro specific complex rubber
Sealing rod carries out waterproof.The structure is relatively simple, and base top surface can be prevented in the case where bedplate expansion joint width is constant
Rainwater is embedded to expansion joint.But, when winter approached, concrete shrinkage amount increase, expansion joint becomes wider, compounded rubber sealing
Hydro-expansive rubber bar on rod can not play sealed effect completely, and the phenomenon of leak still occurs.In addition by compared with
After long-time, aging disrepair phenomenon occurs in rubber, the problem of also having water inlet.
Utility model content
The purpose of this utility model seeks to solve a kind of the not enough flexible there is provided new non-fragment orbit of above-mentioned background technology
Stitch hermetic water-proof structure.
The technical solution of the utility model is：A kind of non-fragment orbit expansion joint hermetic water-proof structure, it is characterised in that：Including

Point sealing plate, the base of water-stop sheet both sides and expansion joint both sides is sealedly and fixedly connected, the two ends of water-stop sheet along its length and
The sidepiece of base is flushed.
Further described water-stop sheet includes two blocks of steel plates, and two pieces of steel plate one end are stretched into base end and base is sealed
It is fixedly connected, the end of two pieces of steel plate other ends is mutually spliced to form the groove-like structure that cross section is " V " type.
Further two blocks of described steel plates are mutually spliced to form the groove-like structure of tip " V " type directed downwardly.
The bottom land of further described water-stop sheet middle is higher than the bottom land at its two ends.
The bottom land of further described water-stop sheet end is higher than the bottom land of its other end.
Further described base end offers mounting groove；Described mounting groove is to be arranged along expansion joint length direction
U-type groove；Described steel plate sidepiece extend into mounting groove and is sealedly and fixedly connected with base.
Further also include the fluid sealant positioned at the closure expansion joint of expansion joint upper end, fluid sealant is located at the upper of water-stop sheet
Side.
Advantage of the present utility model has：
1st, by setting water-stop sheet effectively to prevent rainwater from entering below base, the water-stop sheet of steel can adapt to
The flexible of base is pullled, and will not produce destruction；
2nd, the water-stop sheet structure of V-type can be good at directing water into the both lateral sides of base, it is to avoid water enters base
Lower section, V-structure to adapt to the flexible performance of base more preferable；
3rd, the installation difficulty of water-stop sheet can be effectively reduced by digging mounting groove in base sidepiece, and mounting groove is located at base
In the middle of sidepiece, it is to avoid sidepiece fluting causes the reduction of base intensity；
4th, fluid sealant is set in the upper end at expansion joint, can be good at playing a part of draining, water proof, fluid sealant is all in addition
It is material cheap and easy to get, is convenient for changing.
The utility model is by setting the water proof steel plate of V-type to can be good at playing a part of waterproof water proof, effective solution
Water of having determined, which is entered, causes bedding to steep bad the problem of below base, V-structure has the flexible ability of good adaptation base, tool
There is great promotional value.
