It is a key component in the grouting process and is used to guide the grouting material to the place that needs to be reinforced or repaired. Grouting can be divided into two types according to the construction sequence. One is that after the base plate construction is completed, the conduit is buried by drilling to complete the grouting. This method has a complicated construction process, the grouting is prone to leakage, and the construction quality is difficult to guarantee. The other is to complete the construction of the conduit and then the grouting by reserving and pre-buried during the base plate construction. This method is difficult to waterproof the base plate and is prone to water seepage, which affects the usability and aesthetics of the building. Most of the grouting pipes have only one grouting opening, which is prone to blockage. Utility Model Content

[0021] A basement floor penetrating shallow post-grouting reserved pipeline structure comprises a basement floor 1, wherein a first grouting pipe 2 and a second grouting pipe 3 are penetrated on the basement floor 1, one end of the second grouting pipe 3 is connected with the first grouting pipe 2, and the other end is located at a water collection well 11 and is connected with the outside world and is higher than the top surface of the basement floor 1, the first grouting pipe 2 and the second grouting pipe 3 are connected by a joint connector 8, a wooden plug 5 is provided at one end of the second grouting pipe 3 that is connected with the outside world, an asphalt hemp layer 6 is sealed in the first grouting pipe 2, a second grouting branch pipe 31 for pressure relief is also provided on the peripheral side of one end of the second grouting pipe 3 that is away from the first grouting pipe 2, and the second grouting pipe 3 is connected with the outside world by a joint connector 8. The second grouting branch pipe 31 is arranged perpendicular to the second grouting pipe 3. By setting the first grouting pipe and the second grouting pipe, and setting the second grouting branch pipe on the peripheral side of the second grouting pipe, unlike the traditional single-segment grouting pipe, the grouting pipe of the present application adopts a two-segment assembly design. This segmented assembly method is more convenient during installation, reduces the difficulty of construction, and improves the overall stability, making the grouting pipe more sturdy and reliable. Two ports are designed on the top of the second grouting pipe, one is the side grouting port, and the other is the top overflow port, so that the grouting material can be more evenly distributed to the area that needs to be reinforced. At the same time, the overflow port can be used to promptly remove excess grouting material to avoid blockage problems.

[0022] Preferably, the ends of the second grouting pipe 3 and the second grouting branch pipe 31 connected to the outside are both provided with a conduit cover 30, and the second grouting pipe 3 is 150 mm higher than the top surface of the basement floor 1. By providing the conduit cover and taking top sealing measures, and by adopting a special segmented assembly and waterproof design, the connection between the floor and the grouting pipe is made more secure, and through grouting, the bearing capacity of the deep soil layer and the side friction resistance and end resistance of the pile foundation can be effectively improved, thereby ensuring the stability of the overall structure.

[0023] Preferably, the length b of the wooden plug 5 is 200 mm, and one end thereof is placed on the conduit cover 30 .

[0024] Preferably, an end of the first grouting pipe 2 away from the second grouting pipe 3 is provided with an asphalt cover 20 for sealing the asphalt hemp layer 6, the length of the asphalt cover 20 is 450 mm, the asphalt cover is formed by wrapping asphalt + fiber mesh cloth, and the bottom of the grouting pipe is sealed with asphalt hemp.

[0025] Preferably, the length c of the asphalt hemp layer 6 is 200 mm, and the deep soil layer and pile foundation have insufficient bearing capacity, which may cause serious structural problems. The present application adopts a special segmented assembly and waterproof design to make the connection between the bottom plate and the grouting pipe more secure. Through grouting, the bearing capacity of the deep soil layer and the side friction and end resistance of the pile foundation can be effectively improved, thereby ensuring the stability of the overall structure.

[0026] Preferably, two waterproof steel plates 4 are provided in the middle of the second grouting pipe 3, which effectively isolate the penetration of external water and improve the sealing performance inside the grouting pipe. These measures together constitute a powerful external waterproof system.

[0027] Preferably, the basement floor 1 includes a concrete base 10 and a water collection well 11, and the lower end of the first grouting pipe 2 is penetrated through the lower side of the concrete base 10 and passes through the concrete base 10. By arranging the first grouting pipe to pass through the concrete base, the bearing capacity of the deep soil layer or the pile foundation is effectively improved, and the waterproof performance and structural stability of the floor are ensured. After grouting, the bearing capacity of the deep soil layer and the side friction resistance and end resistance of the pile foundation can be effectively improved, thereby ensuring the stability of the overall structure.

First, the setting of two water-stopping steel plates effectively isolates the penetration of external moisture; secondly, the water-swellable waterstop strip (not marked in the figure) at the bottom of the first grouting pipe can expand rapidly when encountering water to prevent moisture from penetrating. On the inner side of the first grouting pipe, the upper and lower ends are sealed with asphalt paste, which effectively isolates the entry of moisture and improves the sealing performance of the inside of the grouting pipe. These measures together constitute a powerful external waterproof system.

[0030] Preferably, the length d of the waterproof coiled material 7 is 200 mm.

[0031] Specific construction process:

After the cushion layer construction is completed, start the waterproof layer construction. On the side of the conduit, the waterproof layer is turned up by no less than 200mm. At the turned-up node, the waterproof membrane is reinforced, and asphalt grease is used for waterproof sealing and tied tightly.

[0033] Prepare the second grouting pipe and take measures to seal the top, install two waterstop steel plates in the middle of the second grouting pipe, install the second grouting pipe on the top of the first grouting pipe through the joint connector, then complete the bottom plate reinforcement binding and concrete pouring, and the construction is completed.
