[0079] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0080] A method for constructing a culvert based on rainwater and sewage separation includes the following steps: During construction in the culvert, a moving vehicle 4 is placed on the top end face of the culvert using a traction chassis. The moving vehicle 4 is then separated from the traction chassis, activating the hydraulic device 5 and generator set 6. The hydraulic device 5 provides high-pressure fluid for construction, and the generator set 6 provides current for construction. A ladder 9 is placed between the upper end face of the vertical platform 11 and the top end face of the culvert. Construction personnel then access the walkway platform 19 via the ladder 9.

[0081] The outriggers 8 are extended, the vehicle 4 is lifted off the ground, and the truck-mounted crane 7 is operational. The first retaining wall plate 1 is lifted from the hanger 92 and placed on the inlet of the culvert, blocking the inlet. After the water in the culvert is drained, the second retaining wall plate 2 is lifted from the hanger 92 and placed on the outlet of the culvert, blocking the outlet. The support plate 14 is placed on the ground of the culvert. The upper end of the support rod 15 is connected to the upright plate 11 with bolts to fix and support the upright plate 11. The wire rope 91 is lifted from the cargo box 93, and one end of the wire rope 91 is connected to the second ear seat 16 located on the first retaining wall plate 1 through a wire rope lock to put the wire rope 91 in a taut state. Then, the other end of the wire rope 91 is connected to the second ear seat 16 located on the second retaining wall plate 2 through a wire rope lock.

[0082] The pipe rack 3 is lifted from the cargo box 93. The second pipe section 31 of the first pipe rack 3 is fitted and connected to the first pipe section 12 located on the first retaining wall plate 1. The flange section 32 of the first pipe rack 3 is connected to the upright plate section 11 located on the first retaining wall plate 1 using bolts. The second pipe section 31 of the second pipe rack 3 is fitted and connected to the first pipe section 12 located on the second retaining wall plate 2. The flange section 32 of the second pipe rack 3 is connected to the upright plate section 11 located on the second retaining wall plate 2 using bolts. Two adjacent second pipe sections 31 located on other pipe racks 3 between the first and second pipe rack sections 3 are connected together, and two adjacent flange sections 32 are connected to each other by bolts and nuts. Sealant is applied to the joint between the two adjacent second pipe sections 31. When the water level on the vertical plate section 11 of the first retaining wall 1 corresponds to the first pipe section 12 on the first retaining wall 1, the first pipe section 12 and the second pipe section 31 discharge the water flow from the inlet of the culvert to the outlet of the culvert.

[0083] The construction equipment is placed on the upper guide rail plate 33, and the construction workers walk on the ladder pole 35 to carry out rainwater and sewage diversion construction and culvert maintenance work in the culvert.

[0084] After completing the construction work for separating rainwater and sewage in the culvert and the maintenance work on the culvert, the pipe rack 3 and wire rope 91 between the first retaining wall plate 1 and the second retaining wall plate 2 are removed. Using the truck-mounted crane 7, the pipe rack 3 and wire rope 91 are placed into the cargo box 93. The bolts between the upper end of the support rod part 15 and the upright plate part 11 are unscrewed, and the support plate part 14 is flipped upward to close with the upright plate part 11. Then, the upper end of the support rod part 15 is connected to the upright plate part 11 with bolts, so that the support plate part 14 is separated from the ground of the culvert. The ladder 9 is placed into the cargo box 93. Using the truck-mounted crane 7, the first retaining wall plate 1 and the second retaining wall plate 2 are placed on the hanger 92, so that the outrigger 8 is in the retracted state, and the hydraulic device 5 and the generator set 6 are in the non-working state.

[0085] In verifying this invention, the inventors abandoned the existing technical features of sealing the culvert inlet and having construction workers stand on the culvert floor to carry out construction work. Instead, they first proposed a technical feature of extending a construction track within the culvert inlet, resulting in the first unexpected technical effect: clearing the water flow in the culvert and eliminating the need for bypass diversion, thus optimizing the construction space. The second unexpected technical effect: facilitating access for construction workers to the culvert and ensuring their safety. The third unexpected technical effect: enabling integrated transportation of construction materials to the construction site, providing a self-contained power source, and eliminating the influence of other external factors on the construction.

[0086] In a second embodiment of the present invention, the first retaining wall plate 1, the second retaining wall plate 2, and the pipe rack 3 are interconnected in such a way that a construction track extends into the opening.

[0087] In this embodiment, the pipe gallery frame 3 is connected to the first retaining wall plate 1 and the second retaining wall plate 2 by installing an intermediate drainage support beam frame in the opening.

[0088] In this embodiment, a first accessory device is also included and is disposed between the first retaining wall plate 1 and the second retaining wall plate 2. The first accessory device is a steel wire rope 91.

[0089] In this embodiment, a second accessory device is also included and is disposed on the first retaining wall plate 1 and the second retaining wall plate 2. The second accessory device is configured as a ladder 9.

[0090] In this embodiment, a third accessory device is also included, and the third accessory device is configured such that the first wall plate 1, the second wall plate 2, the pipe rack 3, the first accessory device and the second accessory device are distributed correspondingly. The third accessory device is configured to include a moving vehicle 4, a hydraulic device 5, a generator set 6, a truck-mounted crane 7, outriggers 8, a hanging bracket 92 and a cargo box 93.

[0091] The second embodiment of the present invention is based on the first embodiment.

[0092] The second embodiment of the present invention includes the following steps: the first retaining wall plate 1 and the second retaining wall plate 2 enable the installation of a sealing construction platform at the opening of the culvert; the pipe gallery frame 3 enables the installation of an intermediate drainage support beam frame in the opening; and the construction track extends into the opening.

[0093] The second embodiment of the present invention is based on the first embodiment.

[0094] This invention has the following characteristics:

[0095] 1. Due to the design of the first retaining wall plate 1, the second retaining wall plate 2, and the pipe rack 3, the first retaining wall plate 1 and the second retaining wall plate 2 enable the installation of a sealing construction platform at the culvert opening. The pipe rack 3 enables the installation of an intermediate drainage support beam in the opening and the extension of a construction track in the opening. This solves the technical problems of sealing the water inlet of the culvert and allowing construction personnel to stand on the culvert ground for construction work, thus improving the efficiency of culvert inspection and maintenance.

[0096] 2. Due to the design of the steel wire rope 91, a rope connection was achieved between the first retaining wall plate 1 and the second retaining wall plate 2.

[0097] 3. The design of ladder 9 enables the provision of access for construction personnel.

[0098] 4. Due to the design of the moving vehicle 4, hydraulic device 5, generator set 6, truck-mounted crane 7, outriggers 8, hanging frame 92 and cargo box 93, the transportation of the first retaining wall 1, the second retaining wall 2, the pipe rack 3, the wire rope 91 and the ladder 9 is realized.

[0099] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0100] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0101] Other technical features that connect with the first retaining wall plate 1, the second retaining wall plate 2, and the pipe rack 3 extending into the opening are also embodiments of the present invention. Furthermore, the technical features of the above embodiments can be combined arbitrarily. In order to meet the requirements of the Patent Law, the Patent Implementation Regulations, and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

Place the ladder (9) into the cargo box (93), and use the truck-mounted crane (7) to place the first retaining wall plate (1) and the second retaining wall plate (2) onto the hanger (92), so that the outriggers (8) are in a retracted state, and the hydraulic device (5) and the generator set (6) are in a non-working state.
