Abstract
The utility model discloses a railway tunnel arcwall face anti-icing hydrophobic angle specialized tool, include: handle, connecting rod and base plate, the middle part fixed connection of connecting rod one end and handle, the one end fixed connection of handle is kept away from with the connecting rod to the upper surface of base plate, and the bottom surface of base plate is the array and is provided with a plurality of toper archs, the utility model discloses a setting up the toper arch that the array was arranged at the construction face of base plate, when constructing tunnel vault surface, not only accomplished paining of wall concrete material, still form at the concrete surface through pressing and not less than 105 toper pits, make the tunnel surface remain good hydrophobicity with the contact angle of water throughout.
Description
Technical Field
The utility model relates to a tunnel construction technical field, more specifically the utility model relates to a hydrophobic angle specialized tool of anti-icing of railway tunnel archway face that says so.
Background
The application of concrete in the building industry is very wide, and the water resistance and the impermeability of the concrete in large-scale underground engineering, underground traffic rail engineering and roof roofing become industrial difficulties; particularly, tunnel water leakage can form arch columns on top ice and side ice on two sides of a railway, when the ice columns in the tunnel invade into the tunnel building clearance, the running of a train can be seriously influenced, therefore, concrete coated on the surface of the tunnel contains an additive for manufacturing a hydrophobic and anti-sticking surface, the anti-icing effect is achieved by utilizing the excellent water-resistant adhesion performance of the additive, but after multiple icing and deicing cycles, the contact angle of the additive is gradually reduced, and the hydrophobic effect is weakened.
Therefore, how to provide a special tool for the anti-icing hydrophobic angle of the railway tunnel arch surface to improve the hydrophobic effect of the tunnel surface is a problem to be solved by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the above-mentioned technical problem among the prior art to a certain extent at least, provide a railway tunnel archway anti-icing hydrophobic angle specialized tool.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a special tool for preventing icing and draining corners of railway tunnel arch surfaces comprises: a handle;
one end of the connecting rod is fixedly connected with the middle part of the handle;
the upper surface of base plate with the connecting rod is kept away from the one end fixed connection of handle, the bottom surface of base plate is the array and is provided with a plurality of toper archs.
Further, each conical projection has an included angle α of 105 ° in a longitudinal section.
Further, the diameter a of the bottom surface of each conical projection is 7.5mm, and the height b of each conical projection is 5.75 mm.
Further, the length of the substrate is 260mm, the width of the substrate is 160mm, and the thickness of the substrate is 15 mm.
Can know via foretell technical scheme, compare with prior art, the utility model discloses a setting up the toper arch that the array was arranged at the construction face of base plate, when constructing tunnel vault surface, not only accomplished smearing of wall concrete material, still form at the concrete surface through pressing and be not less than 105 conical depression, make the contact angle of tunnel surface and water remain good hydrophobicity throughout.
