[0038] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0039] With the rapid development of highway, railway bridges and urban elevated roads, the construction method of cast-in-place bridges is becoming more and more common. Cast-in-place bridges need to be cast on site by installing formwork. The transverse slope of the bridge deck refers to the transverse inclination of the bridge deck in the plane layout of the bridge. The slope of the bridge deck in the direction perpendicular to the route (transverse) is the transverse slope of the bridge deck. There are three ways to set the transverse slope of the bridge deck, namely natural slope, transition slope and curved slope.

[0040] The degree of the transverse slope of the bridge deck is generally between 1.5% and 3%. The transverse slope of the bridge deck is mainly to facilitate drainage and avoid the formation of a "water film" on the bridge deck, which hinders driving safety. Its slope is the ratio of the inclined height to the width. There are many ways to set the transverse slope of the bridge deck, such as setting a triangular cushion during paving; making the driving lane slab into an inclined surface; setting a transverse slope on the top of the pier, etc. The specific degree of the transverse slope will be determined based on factors such as the design requirements, use conditions and actual engineering conditions of the bridge. For example, a bridge on a highway has a design speed of 100km / h, adopts a two-way four-lane standard, and the transverse slope of the bridge deck is set to 2%. In actual engineering, it is necessary to comprehensively consider factors such as drainage effect, driving safety, bridge structure, construction difficulty and economic cost to reasonably determine the degree of the transverse slope of the bridge deck. At the same time, there may be some differences in bridges of different regions and types, and relevant specifications and standards should be followed during design.

[0041] In order to pursue the accuracy of the cross slope of the bridge deck, the accuracy of the cross slope of the bridge deck needs to be accurately controlled during the construction process. Traditional cross slope accuracy control tools are inconvenient to use and it is difficult to ensure the cross slope of the bridge deck construction. The cross slope accuracy control device for the cast-in-place bridge deck provided by this application can make the laser emitting device emit lasers at a preset angle by rotating the rotating shaft. Construction personnel can refer to the laser construction at a specified tilt angle to ensure the slope of the bridge deck.

[0069] According to the above technical features, the working principle of the cast-in-place bridge deck cross slope accuracy control device provided by this application in actual application scenarios is:

[0070] like Figure 6 As shown, Figure 6 It is a schematic diagram of the use state of the bridge deck cross slope precision control device of the cast-in-place bridge, in which A is the horizontal line, B is the laser beam, and C is the inclination angle of the laser beam B in the horizontal direction;

[0071] Before use, the first horizontal base is set on the bridge deck, the three support rods 102 are rotated, and the horizontality of the support plate 102 is adjusted with reference to the first level meter 11 until the support plate 102 is fixed horizontally. At this time, the first pillar 2 is fixed vertically, the sleeve 3 is sleeved on the upper part of the first pillar 2, the laser emitting device 7 is fixed by the clamping mechanism 6, and the shaft 4 is inserted into the connecting ring 301, the clamping mechanism 6 or the shaft 4 is rotated, and the direction of the laser emitting device 7 is adjusted with reference to the degree of the dial 8 pointed by the pointer 9, so that the laser beam emitted by the laser emitting device 7 reaches a predetermined inclination angle, and the shaft 4 is fixed by the first locking screw 5;

[0072] When in use, the laser emitting device 7 is turned on, and the laser emitting device 7 emits a laser beam inclined at a certain angle. Construction workers can refer to the laser beam for construction, and the bridge deck should be parallel to the laser beam, that is, the distance between the laser beam and the bridge deck is equal;

[0073] During the construction process, construction workers can use the measuring mechanism to measure the distance between the laser beam and the bridge deck, specifically:

[0074] Place the bottom end of the vertical plate 12 on the starting point of the bridge deck slope (which can be the center point of the bridge deck), swing and adjust the upper part of the vertical plate 12, and adjust the horizontal plate 13 to be horizontal with reference to the second level 14. At this time, the vertical plate 12 is in a vertical state, and the laser beam falls on the side of the vertical plate 12 with the length mark. Check the length mark reading corresponding to the laser beam to obtain the standard length h1;

[0075] During the construction process, measure whether the slope of the bridge deck at a certain location is qualified, place the bottom end of the vertical plate 12 on the measuring point, swing and adjust the upper part of the vertical plate 12, and adjust the horizontal plate 13 to be horizontal with reference to the second level 14. At this time, the vertical plate 12 is in a vertical state, and the laser beam falls on the side of the vertical plate 12 where the length mark is set. Check the length mark reading corresponding to the laser beam to get the length h2. Because the bridge deck should be parallel to the laser beam, that is, h2 should be equal to h1, then by comparing h2 and h1, it can be determined whether the slope of the bridge deck at that location is qualified.
