Description
Technical Field
The utility model relates to the technical field of building construction, in particular to a pre-buried installation integrated drainage facility for a rail bearing layer of a high-speed rail station.
Background
The large and oversized high-speed rail station houses adopting the overhead platform mode at present have the following characteristics that the embedding and the installation of the drainage facilities of the bearing rail layer are very important (see figure 1). In view of the intensive demands of land utilization, the lower space of an elevated platform is generally arranged to have the functions of a waiting hall, a parking lot, an outbound hall, urban corridor, business and the like, and the rail bearing layer is strictly forbidden to leak water; in the overhead platform mode, a rain shed is usually arranged only in a platform area, a cover is not arranged above a rail running area, the overhead platform belongs to an outdoor space, and rainwater invades a rail bearing layer. Meanwhile, the water supply and sewage discharge pipe ditches of the trains and the motor cars are arranged on the rail bearing layer, and have drainage requirements such as pipeline leakage, overhauling and emptying, water supply/sewage discharge operation residual water and the like; as a train passing area, a rail bearing layer has a special important position, and the structure of the rail bearing layer has a plate thickness (generally reaching 500-600 mm), a beam height (more than 2 m), a main rib diameter of large diameter (about phi 40) and a small clear distance (about 50 mm), and is provided with wings at the periphery of a column. In view of the above characteristics, all holes and embedded parts penetrating through the bearing rail layer need to be implemented in place synchronously with the structure; the bearing rail layer structure and elevation have specificity, the arrangement limitation of drainage points is larger, and the advantages and disadvantages of point selection often determine the advantages and disadvantages of drainage facility functions.
In the prior art, drainage points are arranged in a pipe ditch, phi 300 holes are reserved, DN150 floor drains are installed in the later stage, and the reservation (burying) and installation are implemented step by step (as shown in figures 1 and 2); the embodiment is suitable for the installation of the floor drain on the floor slab with the thickness of 100-150 mm. When the steel bar is used for a rail bearing layer, holes are reserved on a beam, 4 groups of steel bars with the diameter of 40mm are affected due to the fact that the holes are large, the steel bars are not easy to bend, bending space is insufficient, and broken steel bar treatment is needed; the construction difficulty is high, and the structural strength is weakened; in addition, when in installation, the water resistance of the pipeline and the circumference of the hole is difficult to treat; structural reinforcement measures are not easy to take.
In the prior art, drainage points are arranged in a pipe ditch, a phi 219 steel sleeve pipe is pre-buried, a DN150 drain pipe and a pipe orifice dirt blocking grate are installed in the later stage, a floor drain is not installed, and the steps of reservation (burying) and installation are implemented; in the embodiment, the 'hole and the sewage blocking grate' are used for replacing the floor drain, so that the drainage capacity is greatly reduced. To achieve the same drainage capacity as the floor drain, the pipe diameter needs to be enlarged, and drainage points are increased; affecting 3-4 groups of steel bars, the bending space is still insufficient, and only broken steel bars can be processed; in addition, the thickness of the sleeve wall is required to be increased, the steel bars are welded on the sleeve to reinforce the structure, and the construction difficulty is high; the pipe diameter is increased, the drainage point is increased, and the system is complex; the water-proof treatment is needed to be carried out between the drain pipe and the embedded pipe in the later period, thus consuming labor; the manufacturing cost is increased;
there is also a prior art that the drainage points are arranged at the side wall of the platform, phi 300 holes are reserved, DN150 floor drains are installed in the later stage, and the reservation (burying) and installation are implemented step by step (as shown in fig. 1 and 2). In the embodiment, the elevation of the waterproof layer in the track area is generally higher than the elevation of the finishing surface of the pipe ditch, so that accumulated water in the pipe ditch can not be drained completely; long-term water accumulation in the pipe ditch has the hidden trouble of water leakage to the lower indoor space.
