Definitions
- the invention relates to the technical field of building engineering, in particular to prefabricated track structure for built-in pump room section of rail transit and construction method therefor.
- ballast beds are widely used in built-in pump room section of rail transit, with problems such as poor construction quality, large manpower consumption, slow construction speed, and poor precision of reserved water pipes, resulting in frequent water accumulation and poor durability of the ballast bed. Further, the track bed is prone to problems such as falling blocks, cracks, voids, and heavy maintenance and repair workload after operation.
- inventors of the present invention researched and designed a prefabricated track structure for built-in pump room section of rail transit and construction method therefor, through carefully research and design, and comprehensive long-term experience and achievements in related industries for many years, to overcome the above-mentioned defects.
- An object of the invention is to provide a prefabricated track structure and construction method for built-in pump room section of rail transit, which can effectively solve the existing technical problems such as poor construction quality, large manpower consumption, slow construction speed, and poor precision of reserved water pipes, resulting in frequent water accumulation and poor durability of the ballast bed, and that the existing track bed is prone to problems such as falling blocks, cracks, voids, and heavy maintenance and repair workload after operation.
- the present invention discloses a prefabricated track structure for built-in pump room section of rail transit, which comprises rails, fasteners, a prefabricated I-shaped track plate and a filling adjustment layer, sequentially from top to bottom.
- Said rail is fixed on the upper surface of the prefabricated I-shaped track plate through the fasteners on both sides, and the lower part of the prefabricated I-shaped track plate is provided with a filling adjustment layer, characterized in that:
- the prefabricated I-shaped track plate includes a rail bearing platform and a prefabricated plate, which are formed in one piece, the plane of the prefabricated I-shaped track plate is an I-shaped structure, the middle of which is connected with a beam, and two ends of the beam in the middle are U-shaped openings, thereby forming a U-shaped catchment pit in the middle, section of the prefabricated I-shaped track plate is polygonal, and lower surface of both sides is provided with a slope surface structure to enhance the adaptability to the tunnel section, the filling adjustment layer are filled between bottom of
- Plate side of the prefabricated I-shaped track plate is respectively provided with a lifting sleeve
- the present invention further discloses a construction method for a prefabricated track structure construction method for built-in pump room section of rail transit, comprising following steps:
- the prefabricated track structure for built-in pump room section of rail transit and construction method therefor of the present invention shows following advantages:
- FIG. 1 and 2 the prefabricated track structure for built-in pump room section of rail transit according to an embodiment of the present invention is shown.
- the prefabricated track structure for built-in pump room section of rail transit includes steel rails 1, fasteners 2, prefabricated I-shaped track plates 3 and filling adjustment layer 7 from top to bottom.
- the steel rails 1 is fixed on the upper surface of the prefabricated I-shaped track plates 3 through the fasteners 2 on both sides.
- a filling adjustment layer 7 is provided below the prefabricated I-shaped track plates 3.
- the prefabricated I-shaped track plates 3 includes a rail bearing platform and a prefabricated plate, both of which are formed in one piece.
- the plane of the prefabricated I-shaped track plates 3 is an I-shaped structure (as shown in the top view of Fig.
- both ends of the crossbeam in the middle are U-shaped openings, thereby forming a U-shaped catchment pit in the middle.
- the section of the prefabricated I-shaped track plates 3 is polygonal, and the lower surfaces on both sides are provided with slope surface structures to enhance the adaptability to the tunnel section.
- the prefabricated I-shaped track plates 3 is connected by a crossbeam and with I-shaped appearance, the filling adjustment layer 7 is only poured in the lower part of the I-shaped structure and is not poured within the range of U-shaped openings at both ends of the crossbeam.
- equipment such as pumping pump can be set up within the scope of the U-shaped structure.
- An adjustment layer 7 are filled between the bottom of the prefabricated I-shaped track plates 3 and the shield pipe segment.
- the filling adjustment layer 7 is made of steel fiber reinforced fine stone concrete.
- the plate sides of the prefabricated I-shaped track plates 3 are respectively provided with lifting sleeves 5 for fixing the prefabricated I-shaped track plates 3.
- the top surface of the U-shaped opening of the prefabricated I-shaped track plates 3 is provided with a ditch cover plate 4, which is used for patrol personnel walking or evacuation in case of emergency.
- Both of a joint between the prefabricated I-shaped track plates 3 and the filling adjustment layer 7, and a joint between the filling adjustment layer 7 and the shield segment are provided with sealed waterproof materials 6 for sealing.
- the bottom of a filling adjustment layer under a middle beam of the prefabricated I-shaped track plate is pre-embedded with a water pipe 9 so that the U-shaped catchment pits 8 are connected with each other.
- the range of the shield segment at the bottom of the prefabricated I-shaped track plates 3 can be reserved for or implanted with steel bar to strengthen the connection between the track bed and the shield segment.
- the filling adjustment layer can be made with material of steel fiber reinforced fine stone concrete, self-compacting concrete or special mortar and so on, with good fluidity.
- the plate side or the upper surface of the prefabricated I-shaped track plates 3 is provided with a lifting sleeve and other devices for hoisting or fixing the track plate.
- the water pipe can be round or polygonal shape.
- the invention is used in the rail transit field to replace the traditional cast-in-place built-in pump room roadbed, and has advantages of simple construction procedure, fast construction speed, high construction precision, low labor intensity, good aesthetics, good durability and the like. It is consistent with expectations of environmental protection, high efficiency and disease reduction of the current rail transit, and has great social benefits.
