[0040] The longitudinal water collecting pipe and the lamp are both arranged in multiple sections, and a lamp installation structure 4 is provided between the longitudinal water collecting pipe and the lamp; a lamp matching its length is installed on each section of the longitudinal water collecting pipe, and the lamp is installed on the side of the longitudinal water collecting pipe located on the bridge pier 14, forming a standard section 13; the operator sequentially installs the standard sections at the bottom of the bridge. The lamp and the longitudinal water collecting pipe are formed into standard sections on the ground, and the installation of the lamp is completed while the longitudinal water collecting pipe is installed; compared with the prior art, the lamp is installed separately at the bottom of the flange plate of the bridge, and only one aerial work vehicle operation is required to complete the installation of the lamp and the longitudinal water collecting pipe, which may improve the construction efficiency to a certain extent and shorten the overall construction period. Secondly, the construction area of ​​the lamp is converted from high altitude to the ground, which reduces the construction difficulty and improves safety. Finally, the lamp is installed on the inner side of the longitudinal water collecting pipe, which is different from the prior art in that it is installed on the bottom of the bridge flange plate. This avoids the longitudinal water collecting pipe from blocking the light of the lamp, can better improve night visibility, show the shape of the bridge, make the overall look more harmonious and beautiful, and enhance the image of the city or region.

[0041] In Example 1, the drainage pipe system includes a vertical downpipe 5 arranged vertically, an inspection port 6 arranged at the bottom end of the vertical downpipe, a transverse drainage pipe 7 along the width direction of the bridge, and a vertical drainage pipe 8 located on the wall beam pier; a plurality of vertical downpipes are arranged at intervals along the length direction of the bridge, and the vertical downpipes are located inside the bridge, connecting the bridge deck and the bottom of the bridge; a longitudinal water collecting pipe is arranged at the bottom of the vertical downpipe, and is connected to all vertical downpipes through a four-way joint; a plurality of transverse drainage pipes are arranged on the longitudinal water collecting pipe, and are connected between the vertical drainage pipe and the longitudinal water collecting pipe.

[0042] In Example 1, the circuit system includes a junction box 9 provided in the wall beam anti-collision guardrail, a vertical threading hole 10 penetrating the wall beam, and a wire 11 connected between the junction box and the lamp; one end of the wire is connected to the junction box, and the wire passes through the vertical threading hole and is connected to the lamp; multiple junction boxes are arranged at intervals along the length of the bridge, and one junction box corresponds to one or more lamps. The circuit system can also take other forms, as long as it includes a lamp fixed on the longitudinal water collection pipe.

[0043] In Example 1, in order to reduce the construction difficulty, simplify the operation, and reduce the installation time to a certain extent, a preferred structure of a lamp installation structure is provided, wherein the lamp installation structure comprises a groove 4-1 provided on the lamp, a protrusion 4-2 provided on the longitudinal water collecting pipe, and a limit pin 4-3, wherein the cross-sectional size of the groove increases from the outside to the inside, and the shape and size of the protrusion match the size of the groove; the groove and the protrusion are arranged throughout the length of the lamp;

[0044] A plurality of latch holes are provided on the back of the lamp in the groove, and latch grooves corresponding to the latch holes are provided on the protrusion; after the lamp is installed in place, the latch holes and the latch grooves are aligned, and the limiting latch is placed in the latch holes and the latch grooves at the same time; and the latch is limited by the backlight panel 3-1 provided by the lamp to ensure that the latch cannot be detached from the latch holes and the latch grooves.

[0045] Other structural forms of lamp installation structures may also be used, for example, the lamp may be directly fixed to the longitudinal water collecting pipe by means of a clamp; or a hook may be provided on the longitudinal water collecting pipe and the lamp may be hung on the hook.

[0046] Example 2

[0047] The present invention also discloses a construction method combining bridge drainage and landscape lighting, comprising the following steps:

[0048] Step 1, construction preparation: Investigate the current ground conditions under the box beam. According to the site conditions, if there is a loose address, the site needs to be hardened to better meet the walking of equipment such as aerial platforms and ensure the safety of the construction process. At the same time, make preparations for the entry of on-site machinery and materials, mainly to prepare materials according to the length of the box beam of the bridge, mainly to determine the required length of the longitudinal water collection pipe at the bottom of the bridge flange plate and the required length of the corresponding landscape lighting lamps, arrange for the corresponding manufacturer to open the mold and produce the required longitudinal water collection pipe and lamps with lamp installation structure, make construction plan preparations, and ensure material supply.

[0049] The longitudinal water collection pipe and the lamp are set to standard sections of the same length; on the longitudinal water collection pipe connected to the horizontal drainage pipe, two sections of the lamp with corresponding lengths are cut from the standard section of the lamp and installed on the longitudinal water collection pipe. The lamp shell is cut to the required length on site, and the corresponding length of the lamp is modified to avoid the final assembly being too long or too short.

[0050] Preferably, the longitudinal water collecting pipe and the lamp adopt standard sections of the same length, the length of the standard section ranges from 5 to 7 meters, and the embodiment in the figure adopts 6 meters; at the same time as the standard section, the lamp in the standard section is connected to the junction box.

[0051] Step 2: In the ground construction area, install one or more sections of lamps on a longitudinal water collection pipe to form a standard section. Then, according to the position of the vertical threading hole at the bottom of the junction box reserved during the bridge construction process, the cables used to pass through the vertical threading holes on the spliced ​​standard parts are prepared for the installation of components at the bottom of the box girder flange plate.

[0052] Step 3: Use a high-altitude work vehicle to install vertical downpipes in the flanges on both sides of the bridge, and use threaded plugs for the inspection ports at the bottom of the vertical downpipes; then install the standard section, and fix the pipe of the standard section to the flange plate at the bottom of the wall beam with a clamp 12, and connect it to the M16 expansion bolt at the bottom of the flange plate at the bottom of the wall beam through a 4mm thick steel plate clamp. Use cork pads to reversely fix the pipe to the bottom plate of the upper beam to prevent the pipe from loosening and displacement.

[0053] The pipes between the standard sections are connected by matching pipe sleeves, and the lamps between the standard sections are connected by cables, and waterproof treatment is done. Put the heat shrink tubing on the wire joints, shrink it by heating, and wrap the joints tightly, or use waterproof tape, first wrap a layer of electrical insulation tape clockwise around the wire joints, then tear the self-adhesive waterproof tape from the middle, wrap it clockwise with the inner part to tighten it, and finally wrap another layer of insulation tape.

[0054] Carry out the threading work at the reserved holes of the flange plate at the end of the box girder. The cable line should be run along the bottom of the beam. The pre-set cable line is introduced upward through the reserved hole into the junction box in the protective guardrail on the top of the beam. Use a cable bridge to fix the wiring at the bottom of the beam to prevent the cable from falling along the vertical hole after threading, which increases the subsequent work. If the cable falls off, it will be repaired by the hanging basket used during the construction of the anti-collision guardrail on the bridge.

[0055] After the installation of finished components of pipelines and lamps is completed, each beam section is used as a unit, and the existing temporary electricity during the construction process is utilized. A special distribution box is equipped to connect the temporary electricity, test the landscape lighting in the beam section, and promptly repair any parts that are not installed in place.

[0056] In this example, the installation point of the landscape lighting fixtures is converted from the traditional high-altitude cable tray to the longitudinal water collection pipe, and the lamps and longitudinal water collection pipes are constructed into standard sections. The assembly work of the standard sections is located on the ground, which realizes the conversion of the construction area of ​​the lamps from high altitude to the ground, reducing the difficulty of construction. Secondly, without affecting the original functionality, the construction of bridge drainage and landscape lighting is organically combined, unified planning and construction management are relatively simpler, and the coordination work and possible problems in the original process are reduced. Finally, after the longitudinal water collection pipe and the lamp are combined, compared with the prior art of installing the lamps and longitudinal water collection pipes on both sides by a climbing vehicle, one climbing vehicle installation is reduced. The combination of the two makes the bridge safer in various situations. Reasonable layout and installation can reduce potential safety hazards, reduce a certain amount of workload, avoid mutual interference and repeated operations, and may improve construction efficiency to a certain extent and shorten the overall construction period.

[0057] In Example 2, in order to solve the problem of the illumination route of the bridge belly light, the lamp is installed on the side of the longitudinal water collecting pipe located at the bridge pier. The lamp is moved from the outside of the existing longitudinal water collecting pipe to the inside of the longitudinal water collecting pipe.

[0058] In Example 2, mutually matching grooves and protrusions are respectively provided on the adjacent surfaces of the lamp and the longitudinal water collecting pipe, and the lamp is slidably connected to the longitudinal water collecting pipe through the matching connection between the protrusion and the groove; and penetrating latch holes and latch grooves are provided on the grooves and the protrusions, and the limit latch simultaneously passes through the latch holes and latch grooves on the lamp and the longitudinal water collecting pipe to achieve a fixed connection between the two. The sliding installation of the lamp on the longitudinal water collecting pipe is achieved through the grooves and the protrusions, and the mutual movement between the protrusion and the groove is fixed by the latch, so that the lamp is fixed on the longitudinal water collecting pipe. This structure allows a large amount of preparatory work to be completed on the ground, reducing the difficulty of construction, simple operation, and reducing the time required for installation to a certain extent.

[0059] Preferably, when the longitudinal water collecting pipe and the lamp adopt the same length of the standard section of 6m, two latches are provided on the standard section, located at both ends of the standard section and 1m away from the end.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
