Abstract
A CRTSIII ballastless track bed plate transverse drainage slope gradient control device relates to the field of high-speed railway ballastless track bed plate construction. The foundation plate is designed mainly for solving the problems that concrete pouring and plastering operation are carried out manually in the construction of the existing foundation plate, and the drainage gradient is difficult to control to the design gradient. It includes the square steel, the walking wheel passes through the axle and installs in square steel left end bottom, the handrail passes through bolted connection at square steel left end top, still include the spatula by the downward sloping gradually from the right side to the left, the welding of spatula upper surface has the steel sheet, the welding has the adjusting screw who upwards extends on the steel sheet, be equipped with the adjusting screw clearing hole on the square steel, adjusting screw stretches out from the adjusting screw clearing hole of square steel on upper portion, it has the nut to twist on the adjusting screw who is located square steel top and below, the right-hand member welding of spatula and the right-hand member welding of square steel are in the same place. The advantage is that can be swift, simple and convenient, effectual horizontal drainage slope of control bed plate.
Description
The technical field is as follows:
the utility model relates to a high-speed railway ballastless track bed plate construction field specifically is a horizontal drainage slope control device of CRTSIII ballastless track bed plate.
Background art:
the CRTSIII slab ballastless track is a ballastless track structural form researched and developed in China, the structure is composed of a CRTSIII track slab, a self-compacting concrete filling layer, an isolation layer, a reinforced concrete base and the like from top to bottom, the base slab is used as a bearing layer of the ballastless track structure, and the construction quality of the base slab plays a role in lifting weight on the durability of the ballastless track. The design requires that the base plate width respectively exceeds 200mm than track board both sides, sets up the horizontal drainage slope of 6% slope in the 250mm within range of base surface both sides, and the variable slope point is located self-compaction concrete layer edge 50mm departments toward the track central line direction, and the purpose prevents that the rainwater from getting into and forms the disease between track board and the base.
At present, the base plate construction adopts the manual work to carry out concrete pouring, vibration and plastering operation, receives the restriction of manual operation level, and the drainage slope often is difficult to control to the design slope, and horizontal drainage slope is not enough makes the rainwater get into self-compaction concrete and base joint portion easily and causes the frost heaving disease, and then influences the engineering quality.
The invention content is as follows:
the utility model aims to solve the technical problem that a horizontal drainage slope controlling means of ballastless track bed plate is provided, its simple structure, easy operation, repeatedly usable, excellent in use effect, the precision of the horizontal drainage slope of improvement bed plate that can be very big.
The purpose of the utility model is realized like this: it includes the square steel, the walking wheel passes through the axle and installs in square steel left end bottom, the handrail passes through bolted connection at square steel left end top, still include the spatula by the downward sloping gradually from the right side to the left, the welding of spatula upper surface has the steel sheet, the welding has the adjusting screw who upwards extends on the steel sheet, be equipped with the adjusting screw clearing hole on the square steel, adjusting screw stretches out from the adjusting screw clearing hole of square steel on upper portion, it has the nut to twist on the adjusting screw who is located square steel top and below, the right-hand member welding of spatula and the right-hand member welding of square steel are in the same.
During construction, the walking wheels are arranged on the base plate template and push the device to walk on the base plate template through the handrails.
The angle of the spatula is adjusted according to the gradient of the horizontal drainage slope of the base plate, then the adjusting screw rod is screwed down, and the right end of the spatula and the right end of the square steel are welded together.
The utility model has the advantages that: adopt this device can be swift, simple and convenient, effectual control bed plate horizontal drainage slope, its simple structure, easy operation, repeatedly usable, excellent in use effect, the precision of very big improvement bed plate horizontal drainage slope.
Description of the drawings:
fig. 1 is a schematic view of the structure of the utility model;
fig. 2 is a schematic side view of the present invention.
The specific implementation mode is as follows:
the present invention will be further explained with reference to fig. 1 and 2;
it includes square steel 1, walking wheel 2 is installed in square steel left end bottom through the axle, 3 bolted connections at square steel left end tops of handrail pass through, still include the spatula 4 by the downward sloping gradually from the right side left, spatula top surface welding has steel sheet 5, the welding has the adjusting screw 6 that upwards extends on the steel sheet, be equipped with the adjusting screw clearing hole on the square steel, adjusting screw stretches out from the adjusting screw clearing hole of square steel in upper portion, it has the nut to twist on the adjusting screw who is located square steel top and below, the right-hand member of spatula and the right-hand member welding of square steel are in the same place.
During construction, the walking wheels are arranged on the base plate template 7, and the device is pushed to walk on the base plate template through the handrails.
The angle of the spatula is adjusted according to the gradient of the horizontal drainage slope of the base plate, then the adjusting screw rod is screwed down, and the right end of the spatula and the right end of the square steel are welded together.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
