[0029] It should be noted here that: during the use of the rainwater pipe 101 and the sewage pipe 102, the purpose of one-way flow between the rainwater pipe 101 and the sewage pipe 102 is achieved through the control component. Through the setting of one-way flow, when the drainage pressure inside the rainwater pipe 101 is relatively large, part of the water can be drained and transported to the inside of the sewage pipe 102, thereby alleviating the drainage pressure inside the rainwater pipe 101, and further achieving the co-linear drainage operation between the rainwater pipe 101 and the sewage pipe 102. In addition, during the one-way flow, the foreign matter that is set between the sealing plate 304 and the circular plate 301 is caused to slide and separate through the rotating component and the extrusion component, thereby ensuring the blocking effect of the sealing plate 304 and the lower end of the circular plate 301, and further ensuring the co-linear effect of the one-way flow of the co-linear pipe 2 in the rainwater pipe 101 and the sewage pipe 102, thereby preventing part of the sewage inside the sewage pipe 102 from flowing back into the rainwater pipe 101.

[0031] It should be noted here that: through the transmission assembly, the push rod 701 and the transmission plate 501 are forced to retract toward the bottom of the installation sleeve 303, and during the movement of the transmission plate 501, the transmission pin 502 is driven to move synchronously. During the movement of the transmission pin 502, the end of the transmission pin 502 slides in the S-shaped transmission groove 503, so that the blocking plate 304 is forced to move. During the movement of the blocking plate 304, the annular groove 1001 and the annular plate 1002 are used to connect the blocking plate 304, so that the blocking plate 304, after being subjected to force, rotates back and forth at a certain angle inside the installation sleeve 303.

[0032] Preferably, the transmission assembly includes a push rod 701 fixed to the lower end of the transmission plate 501, a floating plate 702 for pushing against the push rod 701 is arranged inside the collinear tube 2, the floating plate 702 is located below the mounting sleeve 303, and a guide assembly for assisting the floating plate 702 in guiding after receiving force is arranged between the mounting sleeve 303 and the floating plate 702;

[0033] It should be noted here that: when the drainage pressure inside the sewage pipe 102 is relatively large, part of the water inside the sewage pipe 102 is transported to the inside of the co-linear pipe 2 through the pressure of the water inside the sewage pipe 102 and under the action of buoyancy, the float plate 702 is pushed to move upward inside the co-linear pipe 2. In the process of the upward movement of the float plate 702, the float plate 702 is resisted against the push rod 701, so that the push rod 701 and the transmission plate 501 are forced to move toward the bottom of the installation sleeve 303 and shrink.

[0034] Preferably, the telescopic assembly includes a plurality of sets of sleeves 601 fixed to the lower end of the mounting sleeve 303, a slide rod 602 is slidably connected to the sleeve 601, and one end of the slide rod 602 is fixed to the transmission plate 501;

[0035] It should be noted here that the sleeve 601 and the slide rod 602 assist the telescopic movement of the transmission plate 501 .

[0037] It should be noted here that the movement of the floating plate 702 after being subjected to force is guided by the T-bar 801 and the connecting block 802 .

[0038] Preferably, the extrusion assembly includes an L-shaped plate 901 fixed to the upper end of the blocking plate 304, and multiple groups of extrusion plates 902 are fixed to the lower end of the circular plate 301. Both sides of the lower end of each group of extrusion plates 902 are provided with inclined surfaces 903 for abutting against the end of the L-shaped plate 901 for transmission;

[0039] It should be noted here that: during the rotation of the sealing plate 304, the L-shaped plate 901 is driven to move synchronously. During the movement of the L-shaped plate 901, the L-shaped plate 901 is successively abutted against the inclined surfaces 903 on each group of extrusion plates 902. During the abutment between the end of the L-shaped plate 901 and the inclined surface 903, the L-shaped plate 901, the sealing plate 304 and the mounting sleeve 303 are pushed to move away from the circular plate 301. During the process when the end of the L-shaped plate 901 does not abut against the inclined surface 903, the elastic force of the elastic component causes the L-shaped plate 901, the sealing plate 304 and the mounting sleeve 303 to be reset and the flow hole 302 is blocked by the sealing plate 304.

[0040] Preferably, multiple groups of elastic components are arranged inside the collinear tube 2, and the multiple groups of elastic components are evenly distributed between the collinear tube 2 and the installation sleeve 303 in a state of an annular array;

[0041] It should be noted here that the effect of elastic support is improved by using multiple groups of elastic components arranged in a ring array.

[0042] Preferably, the elastic component includes a mounting frame 401 fixed to the outside of the mounting sleeve 303, the mounting frame 401 is rotatably connected to an elastic cylinder 402 through a pin shaft, one end of the elastic cylinder 402 is slidably connected to a support rod 403, one end of the support rod 403 is rotatably connected to the inner wall of the collinear tube 2 through a pin shaft, the other end of the support rod 403 is located inside the elastic cylinder 402 and is fixed with a mounting plate 404, and a spring 405 for elastically squeezing the mounting plate 404 is installed inside the elastic cylinder 402;

[0043] It should be noted here that the installation sleeve 303 is elastically supported by the elastic force of the spring 405 and the connection between the installation plate 404, the support rod 403, the elastic cylinder 402 and the installation frame 401.

[0044] Preferably, the rotating assembly includes an annular groove 1001 opened on the outside of the blocking plate 304, and the inside of the annular groove 1001 is rotatably connected with an annular plate 1002, the annular plate 1002 is fixed to the inner side of the mounting sleeve 303, and the cross-sections of the annular groove 1001 and the annular plate 1002 are both T-shaped;

[0045] It should be noted here that the annular groove 1001 and the annular plate 1002 facilitate the rotatable connection of the auxiliary sealing plate 304 inside the mounting sleeve 303, and the cross-sections of the annular groove 1001 and the annular plate 1002 are both T-shaped to ensure the stability of the rotational connection.

[0046] In this scheme: a rainwater and sewage co-line drainage structure for water supply and drainage construction of a construction project includes the following steps:

[0047] During the water supply and drainage construction of the construction project, the rainwater pipe 101 and the sewage pipe 102 are laid in sequence at the corresponding positions. During the laying process, the rainwater pipe 101 is placed above the sewage pipe 102. After the rainwater pipe 101 and the sewage pipe 102 are laid, the common line pipe 2 is connected between the rainwater pipe 101 and the sewage pipe 102.

[0048] After the construction is completed, during the use of the rainwater pipe 101 and the sewage pipe 102, because the rainwater pipe 101 is above the sewage pipe 102, and the elastic component inside the common pipe 2 pushes the sealing plate 304 on the installation sleeve 303 to abut against the circular plate 301, the flow hole 302 is blocked, so that the sewage transported inside the sewage pipe 102 cannot pass through the common pipe 2 to enter the rainwater pipe 101. In the process of transporting rainwater inside the rainwater pipe 101, because the common pipe 2 is connected with the inside of the rainwater pipe 101, the water circulated and transported inside the rainwater pipe 101 will generate pressure on the sealing plate 304. When the amount of water transported inside the rainwater pipe 101 increases, the pressure of the water inside the rainwater pipe 101 on the sealing plate 304 increases synchronously. When the pressure of some water on the plugging plate 304 is greater than the squeezing elastic force of the elastic component on the plugging plate 304, the plugging plate 304 is pushed no longer against the circular plate 301 by the pressure of the water inside the rainwater pipe 101. At this time, some water inside the rainwater pipe 101 passes through the flow hole 302 of the circular plate 301 and is transported to the inside of the sewage pipe 102 through the gap between the plugging plate 304 and the circular plate 301, thereby achieving the purpose of one-way flow between the rainwater pipe 101 and the sewage pipe 102. Through the one-way flow setting, when the drainage pressure inside the rainwater pipe 101 is relatively large, some water can be drained and transported to the inside of the sewage pipe 102, thereby alleviating the drainage pressure inside the rainwater pipe 101, and further achieving the co-linear drainage operation between the rainwater pipe 101 and the sewage pipe 102.

[0049] When the drainage pressure inside the sewage pipe 102 is relatively high, part of the water inside the sewage pipe 102 is transported to the inside of the co-linear pipe 2 through the pressure of the water inside the sewage pipe 102, and the floating plate 702 is pushed upward inside the co-linear pipe 2 under the action of buoyancy. During the upward movement of the floating plate 702, the floating plate 702 is abutted against the push rod 701, so that the push rod 701 and the transmission plate 501 are forced to contract toward the bottom of the installation sleeve 303. During the movement of the transmission plate 501, the transmission pin 502 is driven to move synchronously. During the movement of the transmission pin 502, the end of the transmission pin 502 slides in the S-shaped transmission groove 503, driving the blocking plate 304 to move under force. During the movement of the blocking plate 304, the annular groove 1001 and the annular plate 1002 are used to connect the blocking plate 304, so that the blocking plate 304, which is subjected to force, reciprocates at a certain angle inside the mounting sleeve 303. During the rotation of the blocking plate 304, the L-shaped plate 901 is driven to move synchronously. , so that the L-shaped plate 901 is in turn against the inclined surface 903 on each group of extrusion plates 902. In the process of the end of the L-shaped plate 901 being against the inclined surface 903, the L-shaped plate 901, the blocking plate 304 and the installation sleeve 303 are forced to move away from the circular plate 301. In the process of the end of the L-shaped plate 901 not being against the inclined surface 903, the elastic force of the elastic component is used to reset the L-shaped plate 901, the blocking plate 304 and the installation sleeve 303, and the flow hole 302 is blocked by the blocking plate 304. During the rotation of the force, the transmission is used to make the sealing plate 304 reciprocate in the vertical direction towards or away from the circular plate 301. The sealing plate 304 rotates and reciprocates up and down, so that the foreign matter that is set between the sealing plate 304 and the circular plate 301 slides and separates, thereby ensuring the blocking effect of the sealing plate 304 and the lower end of the circular plate 301, and further ensuring the one-way flow colinear effect of the colinear pipe 2 in the rainwater pipe 101 and the sewage pipe 102, thereby preventing part of the sewage in the sewage pipe 102 from flowing back into the rainwater pipe 101.
