Description

Technical Field

[0001] The utility model relates to the technical field of railway bridge construction, in particular to a device for positioning the height difference in the construction of a waterproof and protective layer. Background Technique

[0002] As a large building exposed to the outside world, railways are affected by the outside world, especially the rainwater scouring and soaking caused by rain and snow weather, which affect the durability of the concrete of the bridge, and thus affect the service life of the railway. The construction quality of the waterproof and protective layer provided on the upper surface of the bridge plays a major decisive role.

[0003] As a construction process attached to the bridge, the waterproof and protective layer of the bridge plays a protective role for the bridge by isolating the accumulated water caused by rain and snow from the outside world and other external environmental influences. Among them, the control of the height difference of the protective layer at each cross-section of the bridge plays a decisive control role in the construction quality. Poor height difference control directly affects the water collection slope of the waterproof and protective layer, and thus affects the smoothness of surface drainage. If the accumulated water of the waterproof and protective layer is caused by unfavorable control, it will surely penetrate into the beam body over the years, affecting the service life of the bridge deck and the damage to other attached facilities.

[0004] During the construction of the waterproof and protective layer of the bridge, the traditional method for controlling the height difference is usually to directly measure the elevation of the pouring surface of the waterproof and protective layer by using a tape measure from the three walls (the protective wall, Wall A, and Wall B) and the top surface of the ballast slab respectively. This method is simple, but affected by the errors in the pouring elevations of the three walls (the protective wall, Wall A, and Wall B) and the ballast slab, it is very easy to cause obvious cumulative errors in the construction of the waterproof and protective layer, affecting the water collection effect and causing water accumulation; or using a level to set points at intervals on the top surface of the poured waterproof and protective layer for marking. This method can effectively control the construction elevation effect of the waterproof and protective layer, but the work efficiency is low, the number of users is large, and the input of time and labor costs is relatively large.

During application, by adjusting the level bubble of the second level 8, the vertical sliding scale ruler 2 can be adjusted to be in a vertical state.

[0026] Figure 2 It is a top view of a horizontal plate ruler according to an embodiment of the present invention. As Figure 2 shown, clamping grooves 5 are respectively provided at both ends of the horizontal plate ruler 1, and the vertical adjusting legs 3 are perpendicularly inserted into the clamping grooves 5 and arranged; a buckle 6 is further provided on the clamping grooves 5 for fixing the relative position between the vertical adjusting legs 3 and the horizontal plate ruler 1.

[0027] Specifically, the horizontal plate ruler 1 is a device that provides a unified horizontal line and lateral distance indication for the height difference during the construction of the anti-protection layer. Preferably, the length of the horizontal plate ruler 1 is slightly longer than half of the inner side width of the bridge parapet wall.

[0028] Specifically, length scale lines are provided on the upper surface of the horizontal plate ruler 1, with the zero point located on the side of the vertical wall and corresponding to the inner side edge of the bridge A wall, used to display the length data along the direction of the horizontal ruler, providing a basis for adjusting the height difference of each cross-section in the transverse direction of the anti-protection layer; vertical slots 5 that allow the vertical adjustment legs 3 to penetrate and can be fixed by snap-fasteners are provided at both ends of the horizontal plate ruler 1 to assist in adjusting and controlling the horizontal plate ruler 1 to maintain a horizontal position; the horizontal plate ruler 1 is used above the ballast slab, vertical wall, and parapet wall.

[0029] Preferably, the height of the vertical adjustment legs 3 is higher than the maximum vertical net dimension of the ballast slab, vertical wall, and parapet wall.

[0030] Preferably, multiple vertical sliding scale rulers 2 are respectively arranged at corresponding positions on the inner side of the bridge A wall, both sides of the B wall, both sides of the parapet wall, both sides of the ballast slab, and the center between the tracks.

[0031] Figure 3 It is a schematic application diagram of a device for positioning the height difference during the construction of the anti-protection layer provided according to an embodiment of the present invention. As Figure 3 shown, the working principle of a device for positioning the height difference during the construction of the anti-protection layer provided by the present invention is as follows:

[0032] First, insert the vertical adjustment legs 3 into the slots 5 at both ends of the horizontal plate ruler 1, and vertically insert the vertical sliding scale rulers 2 into the cross-shaped sliding grooves 4 embedded in the horizontal plate ruler 1 to form an initial state;

[0033] Then place the horizontal plate ruler 1 perpendicular to the bridge line direction above the ballast slab, vertical wall, and parapet wall, with the scale "zero point" of the horizontal plate ruler 1 corresponding to the inner side edge of the A wall. Synchronously adjust the vertical adjustment leg 3 on this side to its vertical height to ensure that the "zero point" intersects with the inner side edge of the top surface of the A wall, and fix the vertical adjustment leg 3 at this end through the snap-fastener 6;

[0034] Then, adjust the vertical adjustment leg 3 at the other end (between the ballast slabs of the tracks) according to the first level 7 provided on the upper surface in the middle of the horizontal plate ruler 1. Adjust until the bubble in the first level 7 is centered, that is, until the horizontal plate ruler 1 is absolutely horizontal, and fix the vertical adjustment leg 3 and the horizontal plate ruler 1 through the snap-fastener 6 button in the slot 5. At this time, ensure the stability of the horizontal plate ruler 1.

[0035] Finally, shift multiple vertical sliding scales 2 to the corresponding positions on the inner side of Wall A of the bridge, both sides of Wall B, both sides of the protective wall, both sides of the track slab, and the center between the tracks respectively. Fine-tune the vertical sliding scale 2 left and right according to the adjustment bubble on the second level 8 to ensure that the vertical sliding scale 2 is in a vertical state. Read the horizontal distances from their respective positions to the inner side of Wall A, and calculate the height differences at each position relative to the inner side of Wall A according to the water collection slope, so as to determine the construction top surface positions of the anti-protection layers at each cross-section position.
