Abstract
The invention relates to a ballastless track railway bridge joint differential settlement adjusting device aiming at solving the problem that large differential settlement between a ballastless track railway bridge and a roadbed joint section needs to be adjusted, and especially the problem of large differential settlement between a bridge of a regional subsidence area and a roadbed. The ballastless track railway bridge joint differential settlement adjusting device comprises hydraulic jacking devices (2), a concrete support layer (3), a track board (4) and grouting pipes (5), wherein the hydraulic jacking devices (2) are buried on the top of an embankment filling body (1) at intervals along the extension direction of the road; the concrete support layer (3) is poured on the top of the embankment filling body (1); the track board (4) is arranged on the top of the concrete support layer; and the grouting pipes (5) are arranged in the bottom of the concrete support layer at intervals along the extension direction of the road.
Description
Technical field
The present invention relates to railway, particularly a kind of non-fragment orbit railway bridge pipeline connector relative settlement adjusting device.
Background technology
The non-fragment orbit railway requires very strict to settlement after construction, particularly the relative settlement between roadbed and works requires to be not more than 5mm, the knuckle that differential settlement causes should be greater than 1/1000, roadbed Duan Jun takes engineering measure to carry out ground and handles to satisfy above-mentioned requirements in the design, but when geological conditions variation or construction quality existing problems occurring owing to work progress, may cause the relative settlement of bridge and roadbed section greater than 5mm, particularly in the area of regional subsidence, because handling the degree of depth, the ground of bridge pile foundation and roadbed section has larger difference, when bigger regional subsidence takes place when, relative settlement between bridge circuit is with fairly obvious, substantially exceed the adjusting range of non-fragment orbit fastener and be difficult to and repair, simultaneously also can't accurately predict development trend, urgently need a kind of non-fragment orbit railway relative settlement adjusting device to solve this type of problem for this reason.
Summary of the invention
Technical problem to be solved by this invention provides a kind of non-fragment orbit railway bridge pipeline connector relative settlement adjusting device, the problem that exists the larger difference sedimentation to adjust with effective solution non-fragment orbit railroad bridge and roadbed junction, the especially bigger problem of regional subsidence area bridge and roadbed relative settlement.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Non-fragment orbit railway bridge pipeline connector relative settlement adjusting device of the present invention, it is characterized in that it comprises: the hydraulic lifting device is embedded in embankment filling body top at interval along the circuit bearing of trend; The concrete bearing layer is built in embankment filling body top; The track plate is arranged at concrete bearing layer top; Grouting Pipe is inserted concrete bearing layer bottom at interval along the circuit bearing of trend.
The invention has the beneficial effects as follows, utilize the jacking effect of hydraulic lifting device, raise concrete bearing layer and track plate height to satisfy the requirement of track ride comfort, the cement mortar filling and injecting slurry is carried out in the space that stays after utilizing Grouting Pipe to the lifting of concrete bearing layer, thereby the concrete bearing layer is played supporting role, this invention can solve the problem that non-fragment orbit railroad bridge and roadbed junction exist the larger difference sedimentation to adjust effectively, especially the bigger problem of regional subsidence area bridge and roadbed relative settlement.But this adjustment constructional device has the simple dynamic adjustments rising height of construction, investment than characteristics such as provinces, has popularizing application prospect, and meets environmental protection requirement.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the schematic cross-sectional view of non-fragment orbit railway bridge pipeline connector relative settlement adjusting device of the present invention.
The title of member shown in the figure and corresponding mark: embankment filling body 1, hydraulic lifting device 2, concrete bearing layer 3, track plate 4, Grouting Pipe 5.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
With reference to Fig. 1, non-fragment orbit railway bridge pipeline connector relative settlement adjusting device of the present invention comprises: hydraulic lifting device 2 is embedded in embankment filling body 1 top at interval along the circuit bearing of trend; Concrete bearing layer 3 is built in embankment filling body 1 top; Track plate 4 is arranged at concrete bearing layer top; Grouting Pipe 5 is inserted concrete bearing layer bottom at interval along the circuit bearing of trend.Utilize the jacking effect of hydraulic lifting device 2, raise concrete bearing layer 3 and track plate 4 height to satisfy the requirement of track ride comfort, utilize the space that stays after 5 pairs of concrete bearing layer 3 liftings of Grouting Pipe to carry out the cement mortar filling and injecting slurry, thereby concrete bearing layer 3 is played supporting role, solve the problem that non-fragment orbit railroad bridge and roadbed junction exist the larger difference sedimentation to adjust effectively, especially the bigger problem of regional subsidence area bridge and roadbed relative settlement.
With reference to Fig. 1, described hydraulic lifting device 2 positions and spacing are determined according to the position that the larger difference differential settlement takes place, maximum difference settlement prediction value should be greater than taking place in its permission rising height, and the hydraulic pressure petroleum pipeline of its hydraulic lifting device 2 is embedded in the embankment filling body 1 and draws outside the embankment filling body 1.Hydraulic lifting device 2 transverse widths generally should be greater than 1/3 of concrete bearing layer 3 width, and vertically width is greater than 30cm.
With reference to Fig. 1, described Grouting Pipe 5 adopts boring to stretch into supporting bed 3 bottoms after 3 lifting of concrete bearing layer, makes the secretion of supporting bed 3 bottoms closely knit by slip casing by pressure.
Some aufbauprinciples of the above non-fragment orbit railway bridge pipeline connector relative settlement adjusting device of the present invention that just explains through diagrams, be not be the present invention to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the present invention applies for.
