[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.

[0032] like Figure 1 As shown, a drainage network test platform provided in this embodiment

[0033] A drainage pipe network test platform is used for conducting multi-pipe diameter simulation tests, which is arranged on both sides of a ground operation area 15 and includes a water storage area 4 and a multi-pipe test area 17.

[0034] The water storage area 4 is connected to the multi-tube test area through the slotted buried pipe 1 7, and the multi-tube test area 17 flows back to the water storage area 4 through the slotted buried pipe 2 14, forming a circulating reflux test system.

[0035] The water storage area 4 includes a test pool 1 4-1 and a test pool 2 4-2 which are connected to each other through a connecting pipe 2. A concrete pipe 1 is placed in the test pool 1 4-1 to simulate the test of the concrete pipe 1 with water. The test pool 2 4-2 is connected to a slotted buried pipe 7 through a water pump 5 to provide water for the test.

[0036] The multi-tube test area 17 includes three pipeline test positions, which are used to place concrete pipes 10 (the three concrete pipes 10 for testing can be a combination of different diameters, or the same diameter). Both ends of each of the three pipeline test positions are connected to inspection wells 9, so that there are six inspection wells 9 for the three pipeline test positions.

[0037] One end of each inspection well 9 is connected to the slotted buried pipe 7 through a pipeline with a gate valve 8. The water supply of the slotted buried pipe 7 is controlled by the gate valve 8 to introduce test water from the slotted buried pipe 7.

[0038] The other end of each inspection well 9 is connected to the sump 13 through a pipeline with another gate valve 8, and the gate valve 8 can be used to control the drainage of the inspection well 9 into the sump 13. The sump 13 is then connected to the slotted buried pipe 14 through a water pump 16. The slotted buried pipe 14 is connected to the test pool 4-1 of the water storage area 4 for reflux to realize the circulation test system.

[0039] By using a pipe with a gate valve 8 at both ends of each inspection well 9 to open and close the slotted buried pipe 7 and the sump 13, during testing, according to the test requirements, the corresponding gate valves 8 of the inspection wells 9 at both ends of different pipeline test positions can be opened and closed, thereby achieving separate testing of the corresponding concrete pipes 10 at different pipeline test positions, which can be suitable for more application scenarios.

[0040] Furthermore, in this embodiment, a movable walkway board 11 connected to the ground operation area 15 is provided on the multi-tube test area 17, so as to facilitate the staff to move around and conduct inspection during the test and subsequent maintenance.

[0041] Further, in this embodiment, both the water pump 1 5 and the water pump 2 16 use a flow rate of 1200m 3 / h water pump is used to ensure a fixed flow rate and fixed water depth in pipes with a diameter of DN1500 and below, which is convenient for simulating the current situation of drainage pipes on the construction site; at the same time, it is convenient for process test verification and dialectical process feasibility.

[0042] Further, in this embodiment, the concrete pipe 10 is a concrete pipe with a diameter of DN1500, DN1200, or DN800; the concrete pipe 1 is a concrete pipe with a diameter of DN3500. The gate valve 8 is a DN800 gate valve. The slotted buried pipe 1 is a DN800 slotted buried pipe; and the slotted buried pipe 2 is a DN600 slotted buried pipe.

[0043] Furthermore, in the present embodiment, the inspection wells 9 are covered with grille covers 12 to ensure that no debris falls into the inspection wells when no test is being conducted, thereby avoiding blockage of pipes and gate valves. When it is necessary to conduct tests or to enter the inspection wells for underground operations, the grille covers 12 can be removed at any time to perform maintenance on the inspection wells.

[0044] like Figure 2 As shown, this embodiment also provides an application method based on the above platform, including the following steps:

[0045] Step S1: Test pool 1 4-1 and test pool 2 4-2 in the water storage area are loaded with test water, and two concrete pipes 1 with a diameter of DN3500 are placed in the test pool 1 4-1 to simulate the test of the concrete pipe 1 carrying water.

[0046] Step S2: the test pool 2 4 - 2 is connected to the test pool 1 4 - 1 through the connecting pipe 2 , and water is pumped from the test pool 2 4 - 2 to the slotted buried pipe 1 7 through the water pump 1 5 .

[0047] Step S3: Open the gate valves 8 corresponding to the inspection wells 9 at both ends of the pipeline test position to be tested, and the water flows into the corresponding concrete pipe 2 10 on the pipeline test position.

[0048] The multi-pipe diameter simulation test is realized by opening and closing the gate valves 8 corresponding to the inspection wells 9 at both ends of the pipeline test position.

[0049] Step S4: Open the gate valve 8 on the pipe connecting the inspection well 9 and the sump 13 to drain the water flowing out of the concrete pipe 2 10 to the sump 13.

[0050] Step S5: The water from the sump 13 is pumped to the slotted buried pipe 16 through the water pump 16, and finally flows back to the test pool 1 4-1 in the water storage area 4, forming a circulation test system.

[0051] In addition, by filling sand around the concrete pipe 10 and applying load on the sand above the pipe, the repair effect and mechanical properties of the repair process of the concrete pipe 10 are verified. By applying sand pressure to the concrete pipe 10, the existing road load is simulated, and then the mechanical test of the concrete pipe 10 as a repair pipe buried in sand is carried out.

[0052] Furthermore, in this embodiment, linear sensors can be synchronously arranged in the repair pipe section of the concrete pipe 10 buried by sand to monitor the buried repair pipe for a long time and evaluate the repair effect.
