Description

Technical field

[0001] The present utility model relates to the field of railway bridge construction technology, in particular a device for height positioning during the execution of the waterproof protective layer. Background technology

[0002] The rapid development of China's high-speed rail network provides enormous internal impetus for economic growth. By employing the "bridge instead of road" construction principle, China's railways conserve significant land resources. Bridges account for 90% of the total track length. The construction quality and durability of these bridges determine the railway's service life and, consequently, the sustainability of economic development. As a large structure exposed to the natural environment, the railway is particularly vulnerable to external influences such as rain and snow. Rainwater erosion and moisture penetration affect the durability of the bridge's concrete, thus impacting the railway's lifespan. The quality of the waterproof protective layer applied to the bridge surface plays a crucial role in this process.

[0003] Applying the waterproof protective layer to bridges is a step in the bridge construction process that serves as an adjunct to the bridge itself, helping to prevent the penetration of rainwater, snow, and other environmental elements, thus protecting the bridge. Controlling the height differences of the waterproof protective layer across the various cross-sections of the bridge plays a crucial role in the construction quality. Insufficient height control directly impairs the gradient of the waterproof protective layer for water drainage and thus the smooth drainage of the surface. If water remains trapped in the waterproof protective layer due to inadequate control, it will inevitably penetrate the bridge structure over the years, negatively impacting the lifespan of the bridge surface and other connected structures.

[0004] In the construction process of the waterproofing layer on bridges, the conventional method for controlling height differences is usually carried out by measuring with a tape measure on three walls (protective wall, wall A, wall B) and the top of the ballast bed slab to determine the height of the poured surface of the waterproofing layer. This method is simple, but is affected by measurement errors on the three walls (protective wall, wall A, wall B) and the ballast bed slab, which can easily lead to significant cumulative errors in the application of the waterproofing layer, thereby impairing water drainage and causing water accumulation. Alternatively, a leveling instrument is used to place marks at specific intervals on the top of the waterproofing layer.This method can effectively ensure height difference control of the waterproof protective layer, but it is inefficient and requires many employees, resulting in high time and personnel costs.

Based on the embodiments of this utility model, all other embodiments that a person skilled in the art could achieve without inventive work fall within the scope of protection of this utility model.

The device comprises, as shown in Fig. 1 The following: a horizontal board dimension 1 and several vertical sliding scales 2, wherein a vertical adjustable leg 3 is attached to each end of the horizontal board dimension 1, wherein the vertical sliding scales 2 are connected vertically to the horizontal board dimension 1 via a cross slide 4.

[0016] In particular, scales are attached both on the horizontal board dimension 1 and on the vertical sliding scale 2.

[0017] In particular, the horizontal board dimension 1 is positioned horizontally above the waterproof protective layer of the bridge to be measured by means of the vertical adjustable legs 3;

[0018] In particular, several vertical sliding scales 2 are each moved via the cross slide 4 to the corresponding measuring positions;

[0019] In particular, the multiple vertical sliding scales 2 serve to display the height difference data of the waterproof protective layer in the direction perpendicular to the horizontal board dimension 1.

[0020] Preferably, as in Fig. 1 On the top of the horizontal board dimension 1, a first spirit level 7 is additionally attached, which serves to adjust the horizontality of the horizontal board dimension 1.

[0021] Preferably, the spirit level is positioned in the middle of the upper surface of the horizontal board dimension 1.

[0022] Preferably, as in Fig. 1. A second spirit level 8 is attached to the surface of the vertical sliding scale 2, with the orientation of the second spirit level 8 being perpendicular to the longitudinal direction of the vertical sliding scale 2. In use, the vertical sliding scale 2 can be brought into a vertical position by adjusting the horizontal vial of the second spirit level 8.

[0023] Fig. Figure 2 shows a top view of the horizontal board dimension provided by an embodiment of the utility model. As in Fig. 2. Clamping slots 5 are provided at both ends of the horizontal board dimension 1, wherein the vertical adjustment legs 3 are inserted perpendicular to the horizontal board dimension 1 into these clamping slots 5; wherein additional snap locks 6 are provided on the clamping slots 5 to fix the relative position between the vertical adjustment legs 3 and the horizontal board dimension 1.

[0024] In particular, the horizontal board dimension 1 is a device that provides a uniform horizontal line and transverse spacing specifications for height differences during the execution of the waterproof protective layer. Preferably, the length of the horizontal board dimension 1 is slightly longer than half the width of the inside of the bridge parapet.

[0025] In particular, a length scale is provided on the top surface of the horizontal board 1, the zero point of which is located on the side of the vertical wall and coincides with the inside of wall A of the bridge. This serves to display the length data along the horizontal board and forms the basis for adjusting the height differences of the cross-sections of the waterproof protective layer. Vertical clamping slots 5 are provided at both ends of the horizontal board 1, which allow the insertion and locking of the vertical adjustment legs 3 to support the horizontal alignment of the horizontal board 1. The horizontal board 1 is used above the ballast bed, the vertical wall, and the protective wall.

[0026] Preferably, the height of the vertical adjustable leg 3 is higher than the highest vertical net dimension of the gravel bed slab, the vertical wall and the protective wall.

[0027] Preferably, several vertical sliding scales 2 are attached to the inside of wall A, to both sides of wall B, to both sides of the retaining wall, to both sides of the bridge ballast bed, and at the central position between the tracks. By reading the horizontal longitudinal data at the position of the corresponding horizontal board dimension 1 and calculating the relative height differences based on the drainage slope of the cross-section of the waterproof protective layer, the height of the individual cross-sectional areas is determined and marked using the vertical sliding scale 2 in order to establish the execution height of the waterproof protective layer.

[0028] Fig. Figure 3 shows a schematic application diagram of the device for height positioning during the execution of the waterproof protective layer, which is provided by an embodiment of the utility model. As in Fig.3 The working principle of the device for height positioning in the execution of the waterproof protective layer provided by the present utility model is as follows: First, the vertical adjusting leg 3 is guided through the clamping slots 5 at both ends of the horizontal board dimension 1, then the vertical sliding scale 2 is inserted vertically into the cross slide 4, which is recessed into the horizontal board dimension 1, to form the initial state;

[0029] The horizontal gauge 1 is then positioned perpendicular to the track direction of the bridge above the ballast bed, the vertical wall, and the retaining wall. The "zero point" scale of the horizontal gauge 1 corresponds to the inside of wall A. Simultaneously, the vertical adjustment leg 3 on this side is adjusted so that the "zero point" coincides with the inside of the top edge of wall A, and the vertical adjustment leg 3 at this end is secured by the snap lock 6.

[0030] Then, based on the first spirit level 7, which is attached to the upper central surface of the horizontal board 1, the vertical adjustment leg 3 at the other end (between the gravel bed plates) is adjusted until the bubble of the first spirit level 7 is centered and the horizontal board 1 is perfectly horizontal. The vertical adjustment leg 3 is then fixed to the horizontal board 1 by the snap lock 6 in the clamping slot 5, thus ensuring the stability of the horizontal board 1.

[0031] Finally, several vertical sliding scales 2 are positioned on the inside of wall A, on both sides of wall B, on both sides of the retaining wall, on both sides of the ballast bed, and at the midpoint between the tracks. The vertical sliding scale 2 is adjusted according to the left-right fine adjustment of the air bubble on the second spirit level 8 to ensure that it remains vertical. The horizontal distances of each position to the inside of wall A are then recorded. Based on the drainage slope, the height deviation of each position from the inside of wall A is calculated to determine the installation height of the waterproof protective layer at each cross-sectional position.

[0032] The device for height positioning provided in this embodiment of the utility model for the execution of the waterproof protective layer has the following advantages compared to the prior art: (1) It can effectively ensure the height differences of the cross-sections at the various positions of the waterproof protective layer, ensure the drainage gradient, guarantee a smooth water flow and thus ensure the construction quality; (2) It can effectively increase the efficiency of the execution of the waterproof protective layer and reduce construction costs; (3) It can effectively reduce maintenance costs in the later operational phase of the waterproof protective layer, effectively ensure the durability of the bridge and guarantee the service life of the bridge in order to reduce operating costs.
