[0020] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0022] This specification provides a grid-type rainwater recycling system for underground construction projects. Figure 1 and Figure 5 As shown, it includes several drainage boards 1, drainage pipes 2, observation wells 3, geotextiles 4 and ventilation pipes 5.

[0023] Among them, several drainage boards 1 are set above the underground building; in a possible specific implementation, after the first-level waterproof construction of the basement roof is completed (according to the engineering design), the drainage boards can be laid on the working surface of the waterproof layer. The overlap between the drainage boards adopts the buckle point socket form, and the bottom is sealed with double-sided adhesive tape, with a bonding width of 100mm. Buckle point socket form please refer to Figure 4 As shown, the drain board 1 is provided with matching insert blocks 11 and slots 12 at opposite ends thereof.

[0024] Drain pipe 2 is installed above the underground building, please refer to Figure 2 As shown, the drain pipe 2 includes a permeate collection pipe 21 and a main flow pipe 22. Water on the drain board 1 can enter the permeate collection pipe 21. The permeate collection pipe 21 is closed at one end and connected to the main flow pipe 22 at the other end. In one possible implementation, multiple permeate collection pipes 21 are provided on either side of the main flow pipe 22, forming a fishbone structure with the main flow pipe and the multiple permeate collection pipes. In one possible implementation, the drain board and drain pipe can be laid in two ways: first, lay the board to the designed pipe position, leaving 8cm of space between the boards (the specific space depends on the actual situation and is not limited here), and then install the pipe after the board is laid; second, fix the pipe first and then lay the drain board from the pipe position to both sides.

[0025] The geotextile 4 covers the drainage board 1; in a possible implementation, the geotextiles are connected by sewing, and the side wall geotextile is turned up higher than the drainage board. To ensure that the geotextile is flat, glue is applied to the side wall drainage board to stick it flat, and the upper edge of the geotextile is sealed to prevent soil from entering.

[0026] Observation well 3 collects water from the main pipeline, which is sealed at one end and connected to the observation well at the other. The inlet of the observation well is located below the roof of the underground garage, and the outlet is connected to a reservoir or municipal pipe network. A vent pipe 5 is connected to the drain pipe at one end and extends above the ground at the other. A vent cap is installed on the top of the vent pipe to prevent large particles from entering the pipe.

[0027] It should be noted that the drainage boards are laid using a snap-on method. The width of the adhesive roll used below the overlapped sections is 10cm, and the width of the adhesive roll used at the overlapped sections between the tube and board is 15cm. The side walls of the drainage boards are fixed with 5-8cm adhesive material in the upper and middle sections, and the corners are bonded with 15cm adhesive material between the upper and lower drainage boards. The corners are also bonded with 15cm adhesive material. The film on the surface of the adhesive tape is only removed when the infiltration rainwater collection pipe is installed, so that the boards and pipes on both sides form a whole. Ventilation pipes are installed in appropriate locations. The height of the ventilation pipes should be 20cm higher than the final backfill soil. After installation, brickwork should be laid at the bottom for protection. Before large-scale backfilling, the area must be pre-backfilled manually or mechanically, and warning signs should be placed on the top to prevent damage to the ventilation pipes during backfilling.

[0028] The grid-type rainwater recycling system of this embodiment is laid on the planting roof by laying a grid of seepage water collection pipes and installing breathable pipes. It uses the principle of soil pressure difference drainage to guide the seepage water to flow into the pipes, realizing the transformation of the planting roof from disordered, unorganized, passive drainage to zero-slope, organized, directional, active drainage. It also releases the pressure of water accumulation in the soil layer, thereby curing the serious problem of leakage caused by the waterproof layer being under the action of pressurized water for a long time.

[0029] For further optimization, please refer to Figure 3 As shown, the bottom of the seepage water collection pipe 21 is provided with water inlets 23 on either side. The top of the drain plate is provided with a groove into which the bottom of the seepage water collection pipe can be inserted. The bottom of the water inlet is no higher than the upper surface of the drain plate. This ensures that rainwater can flow smoothly into the seepage water collection pipe. The bottom of the seepage water collection pipe is no higher than the bottom of the water inlet, preventing water that has flowed into the drain pipe from flowing back.

[0030] Further preferably, the observation well 3 is provided with an overflow port 31, the height of the overflow port 31 and the bottom of the observation well being no greater than the height of the main flow pipe and the bottom of the observation well. The overflow port is connected to the water reservoir 4 via a legacy pipe, and the legacy pipe is provided with a check valve.

[0031] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0032] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
