Problems solved by technology

[0003] At present, in the construction of the waterproof protective layer of the high-speed railway, it is necessary to construct the waterproof layer on the surface of the bridge beam between the two rows of ballastless track slabs. The laying amount of polymer asphalt waterproofing membrane is large, the efficiency of manual laying is relatively low, and the laying quality cannot be guaranteed
In addition, the construction method of concrete is to vibrate manually with small vibrating rods, vibrating every other place, which is prone to leakage vibration, and manual vibrating cannot accurately grasp the vibrating time, because the vibrating time of each pl

Example Embodiment

[0045] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0046] See figure 1 As shown, the embodiment of the present invention provides a device for the construction of a bridge deck waterproof layer, which is used for the bridge deck 2 between two adjacent rows of ballastless tracks 1 and the bridge between the ballastless track 1 and the protective wall. For construction on surface 2, first lay the asphalt coil 7, and then pour concrete on the asphalt coil 7, and form a waterproof layer. After the concrete is poured, the concrete vibrating device 4 is used to vibrate and close the concrete, see figure 2 As shown, the concrete vibrating device 4 includes two slide rails 40, a support frame 41, a vibration table 42 and a driver 44. When the bridge deck 2 between two adjacent rows of ballastless tracks 1 is constructed, the two slide rails The rails 40 are separately arranged on two rows of ballastless tracks 1. Whe...

Abstract

The invention discloses equipment for construction of a bridge floor waterproof layer. The equipment is applied to construction of a bridge floor between two adjacent rows of ballastless tracks and abridge floor between each ballastless track and a protecting wall. The equipment comprises a concrete vibrating device, wherein the concrete vibrating device comprise two sliding rails, a support frame, a vibrating table and a driver; the two sliding rails are used for being arranged on the two rows of ballastless tracks or the ballastless tracks and the protecting wall respectively; the support frame is transversely arranged between the two sliding rails, and the two ends of the support frame are movably arranged on the two sliding rails respectively; the shape of the bottom surface of the vibrating table is matched with that of the bridge floor, the vibrating table is connected to the bottom of the support frame through a height adjusting mechanism, and the height adjusting mechanism isused for adjusting height of the vibrating table; the driver is arranged on the vibration table and used for driving the vibrating table to vibrate, so as to vibrate the concrete layer on the bridge floor. Uniform vibration of concrete can be realized rapidly, leaking vibration can be avoided, requirements for concrete elevation and drainage slope of the concrete top surface are met, and the quality of the bridge floor waterproof layer is guaranteed.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a device for construction of a bridge deck waterproof layer. Background technique [0002] Ballastless track concrete bridge deck waterproof layer is a major link to improve bridge durability. High-speed rail ballastless track adopts a waterproof system composed of coiled asphalt waterproof layer and C40 fine stone fiber concrete or C40 reinforced concrete protective layer. [0003] At present, in the construction of the waterproof protective layer of the high-speed railway, it is necessary to construct the waterproof layer on the surface of the bridge beam between the two rows of ballastless track slabs. The laying quantity of polymer bitumen waterproofing membrane is large, the efficiency of manual laying is relatively low, and the laying quality cannot be guaranteed. In addition, the construction method of concrete is to vibrate manually with small vibrating rods, vibrating...
