[0007] The described construction method combining a river across the site with a permanent drainage pipeline is characterized in that: the overall combination and diversion of rainwater, sewage, and river water are solved by a transverse "pin" - shaped concrete box culvert. A dedicated river water circulation channel is set on one side, and the other side is divided into two layers.

[0008] The described construction method combining a river across the site with a permanent drainage pipeline is characterized in that: the upper rainwater channel is discharged by converging into the in-site rainwater pipeline on one side. An overflow port is set on the other side of the rainwater channel. When the in-site rainwater volume is too large, it can overflow through the overflow port and be discharged into the river channel, which can effectively enhance the drainage effect.

[0009] The described construction method combining a river across the site with a permanent drainage pipeline is characterized in that: a secondary recovery pool can be set beside the transverse "pin" - shaped concrete box culvert to supply water for in-site greening and car washing by using rainwater recycling and secondary river water replenishment.

[0010] A construction method combining a river channel and a permanent drainage pipeline across a site is characterized in that the "pin" - shaped concrete box culvert can be constructed by prefabrication or in - situ casting, and anti - permeation concrete is used; when prefabricated concrete construction is adopted, anti - leakage measures should be taken at the joint part.

[0011] A construction method combining a river channel and a permanent drainage pipeline across a site is characterized in that after the construction of the concrete box culvert structure of the concrete structure, the soil is backfilled and compacted, and the top is hardened.

[0012] The beneficial effects of the present invention are as follows: As can be seen from the above technical solutions, the present application provides a construction method combining a river channel and a permanent drainage pipeline across a site. The "pin" - shaped concrete box culvert structure in the transverse section is simple in structure, high in bearing capacity, and has a mature construction technology; it can effectively achieve the diversion of rainwater, sewage, and river water and the secondary recycling of part of the water resources; after the construction of the "pin" - shaped concrete box culvert structure in the transverse section is completed, it can be backfilled and hardened, improving the cross - river commuting efficiency and reducing the risk of people falling into the river.

[0020] The technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope claimed by the present application.

[0021] As Figure 1-6Shown: A construction method combining a river channel across a site with a permanent drainage pipeline, characterized in that: First, the original river channel across the site is excavated by slope cutting of earthwork, and the river channel direction and slope are measured, set out and positioned; Second, a transverse "pin" - shaped concrete box culvert structure is constructed along the river; Then, a secondary recycling pool structure is added at the water - using points within the site to meet the water - using requirements within the site; Finally, after the structure construction is completed, the earthwork is backfilled and compacted, and the road surface is hardened.

[0022] Specifically, the combined diversion of the overall rainwater, sewage and river water is solved by a transverse "pin" - shaped concrete box culvert. A dedicated river water circulation channel is set on one side, and on the other side, it is divided into two layers. The upper part is provided with a rainwater drainage channel, and the lower part is provided with a sewage drainage channel.

[0023] The upper - part rainwater channel is汇 入排出 (should be "drained into and discharged through") the rainwater pipeline within the site on one side. An overflow outlet is set on the other side of the rainwater channel. When the rainwater volume within the site is too large, it can overflow through the overflow outlet and be discharged into the river channel, which can effectively enhance the drainage effect.

[0024] A secondary recycling pool can be set beside the transverse "pin" - shaped concrete box culvert to supply water for the greening and car washing within the site by using rainwater recycling and secondary river water replenishment.

[0025] The "pin" - shaped concrete box culvert can be constructed by pre - casting or in - situ casting, and anti - permeable concrete is used; when pre - cast concrete construction is adopted, anti - leakage measures should be taken for the joint part.

[0026] After the construction of the concrete box culvert structure of the concrete structure is completed, the earthwork is backfilled and compacted, and the top is hardened.

[0027] In the present invention, the original river channel across the site is excavated by slope cutting of earthwork, and the river channel direction and slope are measured, set out and positioned. A transverse "pin" - shaped concrete box culvert structure (such as Figure 1 ) is constructed along the river. A secondary recycling pool structure (such as Figure 4 ) is added at the water - using points within the site to meet the water - using requirements within the site. After the structure construction is completed, the earthwork is backfilled and compacted, and the road surface is hardened.
