The utility model discloses a track board self -compaction concrete fills grouting collection device makes the closely knit degree of track board concrete and come -up volume obtain effectual control, and area is little, simple structure, and it is convenient, with low costs that the clearance is dismantled in the installation for on -the -spot civilization construction is protected, and later stage track board track self -compaction concrete fills the quality and obtains control like this, makes the completion that the construction is swift, guarantee the quality.
Description
Technical field
The utility model relates to self-compacting concrete perfusion equipment technical field, is more particularly a kind of track plates self-compacting concrete perfusion excessive slurry gathering-device.
Background technology
At present in China, CRTSIII plate-type non-fragment orbit be China in conjunction with existing non-fragment orbit technology, by original innovation, integrated innovation with assimilate advanced foreign technologies and further refine them, the up-to-date track system of proposition, has complete independent intellectual property right.So we will greatly develop scientific and technical innovation engineering method at construction link, improve CRTS III type track plates pouring quality and efficiency.
Along with the fast development that China Railway High-speed (Line for Passenger Transportation, inter-city passenger rail) is built, the plate-type ballastless track complete set technology that research and development have independent intellectual property right has become the task of top priority embodying China's high ferro technical level, show national strength, and Ye Shi China high ferro technology is gone abroad necessary.The Ministry of Railways in 2009 in Chengdu to Dujiang weir intercity railways special line, carried out the plate-type ballastless track complete set technology engineering experiment and design innovation work with perfect knowledge property right, and achieved successfully, be formally fixed to CRTS III type track plates in December, 2010.Its test result is intercity in Hubei, Panjin is applied and practice to Yingkou and Shenyang to Dandong passenger dedicated railway line.
CRTS III plate-type non-fragment orbit General structure scheme is the Novel unit platy ballastless track structure of shouldered, primarily of part compositions such as the self-compacting concrete of rail, fastener, precast track plate, arrangement of reinforcement, limited impression, intermediate isolating layer (geotextiles) and reinforced concrete footings.
Track structure adopts unit fraction block structure, at roadbed, all adopts unconnected sectional type block construction between bridge and location, tunnel track plates.Bed plate arranges two limiting block platforms (groove structure) within the scope of every block track plates, and bed plate and self-leveling concrete interlayer arrange intermediate isolating layer.Fastener adopts WJ-8C type fastener.
At present, in non-fragment orbit high-speed railway construction, in self-compacting concrete pouring construction there is following problem in concrete compaction and floating: not adopting an effective measure in 1, traditional self-compacting concrete pouring construction remains that filling concrete has certain height and pressure: otherwise influx height is little, pressure is inadequate, causes plate chamber leakiness; Influx height is large, and pressure is large, track plates floats and exceeds standard 2, traditional self-compacting concrete pouring construction time by manual control influx height, workman's workload is large, and manual operation uncertain factor increases, and takes a lot of work, time-consuming, accurately cannot control, inefficiency, easily occur pouring quality defect.The concrete cleaning difficulty of overflowing during 3, traditional self-compacting concrete pouring construction, pollutes track plates, can not accomplish effective civilized construction.
Utility model content
The purpose of this utility model is the requirement in order to the accuracy and on-the-spot civilized construction improving the control of self-compacting concrete influx height, provides a kind of track plates self-compacting concrete to pour into excessive slurry gathering-device.
The purpose of this utility model is achieved through the following technical solutions:
The perfusion of a kind of CRTS III type track plates is overflow and is starched gathering-device, include bed plate, track plates is provided with above bed plate, filling concrete space is provided with between bed plate and track plates, it is characterized in that: track plates has left and right peep hole, be installed with straight tube respectively in left and right peep hole, straight tube is all set with tee piece, below the side pipe mouth of tee piece, be provided with the basin that gathers materials.
The perfusion of a kind of CRTS III type track plates is overflow and is starched gathering-device, and it is characterized in that: the annular outer wall of described straight tube is provided with external screw thread, straight tube outer wall is provided with scale.
The perfusion of a kind of CRTS III type track plates is overflow and is starched gathering-device, it is characterized in that: the basin that gathers materials is placed on track plates.
During self-compacting concrete perfusion, require that concrete will keep certain height in filling process, can not greatly can not be little, highly large easily cause track plates float-amount supergage, defective; Highly little track plate cavity pressure is little, and self-compaction perfusion leakiness, causes quality accident.
The utility model is after self-compacting concrete is filled into certain altitude for this reason, is discharged by unnecessary concrete, can ensure certain injection pressure, also can ensure that float-amount does not exceed standard.
When unnecessary concrete is discharged by observing, can pollute track plates, cleaning difficulty, can not meet on-the-spot civilized construction, therefore arrange a concrete gathering-device.
The utility model respectively arranges the threeway pvc pipe of 1 Φ 160mm at 2 peep holes of CRTSIII track plates, by taking off plate test, we show that filling concrete height is 15 ~ 20mm, namely require that track plates is 15 ~ 20mmmm to the wide open height of threeway, we adopt screw thread to connect at the threeway mouth of pipe, length scale is had to show above, can free adjustment.
Arrange the basin that gathers materials at threeway mouth of pipe place, requirement can hold certain amount of concrete, adopts diameter 50cm by testing us, the white rust steel basin of degree of depth 10cm.
The utility model has the advantage of:
The utility model can keep filling concrete height effectively accurately, keeps track plate cavity to have constant pressure; Gathering-device effectively can ensure that concrete does not pollute plate face, and concrete is easily cleared up, and ensures the requirement of on-the-spot civilized construction; Floor space is little, and structure is simple, and installing/dismounting cleaning is convenient, and cost is low; The self-compacting concrete pouring quality of such later stage track plates is effectively controlled, and makes quick construction, completing of guaranteeing the quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
