DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] In the present embodiment, the pipelines in the municipal road system are no longer centrally arranged inside the integrated pipe corridor, but are divided into multiple pipe warehouses. A middle warehouse 18 is provided in the middle of the road, which can be a water warehouse. Side warehouses 19 are provided on both sides of the road, which can be gas warehouses and electricity warehouses, respectively. Various pipelines are respectively arranged in the middle warehouse 18 and the side warehouses 19 which are far apart. Different from the current warehouse division technology of the integrated pipe corridor, the warehouse division technology of the present invention can thoroughly guarantee the safe spacing of various pipelines and the actual net distance between the pipelines, thus overcoming the problem that the safe spacing of the pipelines in the integrated pipe corridor is difficult to meet the regulations.

[0029] The aforementioned central warehouse 18 and side warehouse 19 both include a number of CNC side molds 1, the difference being that the central warehouse 18 is formed by a number of CNC side molds 1 arranged symmetrically on both sides, the arrangement direction being along the length direction of the road, the CNC side molds 1 on both sides of the central warehouse 18 are spaced apart and are not close together, and the opening ends of the CNC side molds 1 on both sides of the central warehouse 18 are facing each other. The side warehouse 19 is formed by a number of CNC side molds 1 arranged unilaterally, and similarly the CNC side molds 1 of the side warehouse 19 are also arranged along the length direction of the road, and the opening ends of the CNC side molds 1 of the side warehouse 19 face the outside of the road. The CNC side formwork 1 mentioned above is prefabricated in the factory in advance. Each section of the prefabricated CNC side formwork 1 is preferably 2-3 meters long. The CNC side formwork 1 is made of ultra-high performance concrete (UHPC). The CNC side formwork 1 includes a rectangular side formwork shell 16. The lower surface of the rectangular side formwork shell 16 is integrally connected to the U-shaped side formwork shell 17 downward. The interior of the rectangular side formwork shell 16 is filled with concrete to form a side formwork core 4. The U-shaped side formwork shell 17 is the pipe warehouse of the middle warehouse 18 or the side warehouse 19. Various road pipelines are installed in the U-shaped side formwork shell 17. The prefabricated CNC side formwork 1 is buried in the road layer, wherein the U-shaped side formwork shells 17 of the middle warehouse 18 and the side warehouse 19 are buried in the roadbed 6. In this embodiment, the upper surface of the U-shaped side formwork shell 17 is just flush with the upper surface of the roadbed 6. The top surface elevations of the middle warehouse 18 and the side warehouse 19 after burial are the design elevations of the road curb. The rectangular side mold shells 16 of the middle warehouse 18 and the side warehouse 19 also have the function of curb. Therefore, the size of the CNC side mold 1 is prefabricated in advance according to the designed burial position and the design elevation of the curb.

[0030] Since there is a distance between the symmetrical CNC side molds 1 on both sides of the middle warehouse 18, concrete is poured at the bottom of the CNC side molds 1 on both sides of the middle warehouse 18 to form the warehouse bottom 2. The poured concrete connects the bottoms of the CNC side molds 1 on both sides to form the overall warehouse bottom 2 of the middle warehouse 18. Preferably, the thickness of the concrete poured at the bottom of the CNC side molds 1 on both sides of the middle warehouse 18 is 4 cm. A middle warehouse top cover 5 is also provided on the top of the middle warehouse 18, and brackets 20 are symmetrically provided on the upper part of the inner side walls of the rectangular side mold shells 16 on both sides of the middle warehouse 18. In this embodiment, the brackets 20 are long support blocks fixed on the inner side walls of the rectangular side mold shells 16. The middle warehouse top cover 5 is installed on the brackets 20 on both sides. After installation, the upper surface of the middle warehouse top cover 5 is flush with the upper surface of the middle warehouse 18, thereby achieving closure of the middle warehouse 18. Preferably, the installed middle warehouse top cover 5 can be one or more of a solar top cover and a glass top cover. In this embodiment, the middle warehouse top cover 5 includes two types: a solar top cover and a glass top cover, and is composed of a plurality of solar top covers and a plurality of glass top covers alternately combined. The solar top cover can convert solar energy into electrical energy to provide electricity. Since solar power supply is very common, the structure and principle of solar power supply are not repeated here. In this embodiment, the solar top cover and the glass top cover both include a fixed top cover and a movable top cover, that is, the solar top cover includes a fixed top cover fixed on the bracket 20 and not easy to lift, and also includes a movable top cover that is movable and removable and easy to lift. Similarly, the glass top cover also includes a fixed top cover fixed on the bracket 20 and not easy to lift, and also includes a movable top cover that is movable and removable and easy to lift. The movable top cover is easy to lift so as to inspect the middle warehouse 18. To further facilitate inspection, it is preferred that a ladder 27 is installed on the inner side wall of the rectangular side mold shell 16 of the numerical control side mold 1 of the middle warehouse 18. A resistor wire 25 and an LED light group 28 are provided at the bottom of the solar roof, and both the resistor wire 25 and the LED light group 28 are connected to the solar roof circuit, and the solar roof supplies power to the resistor wire 25 and the LED light group 28.

In summer, the resistor wire 25 can be turned off, and the LED light group 28 can illuminate the central warehouse 18 to provide operating lighting brightness and facilitate the maintenance of the central warehouse 18. The central warehouse 18 with heating function can install pipelines at a shallower position than traditional direct buried pipelines, reducing the amount of excavation and earthwork.
