[0002] The commonly used pre-buried pipes in current construction projects are usually divided into three types: 1. Ordinary pipes; 2. Flexible waterproof pipes; 3. Rigid waterproof pipes. These three types of pipes usually only consider their functions in the later use process, and the measures to prevent concrete, mortar, and water seepage from entering the pre-buried pipes during the construction of the pre-buried pipe wall are mostly to simply plug the buried pipes with filler materials, plastics and other debris during the construction process.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 and Figure 2The embodiment of the present invention provides a pre-buried pipe for an engineering wall, including a pipe body 1 that can be pre-buried in the engineering wall, and also includes a blocking structure for blocking the openings at both ends of the pipe body 1, the blocking structure includes two plugs 20 that can be detachably blocked for blocking the two openings of the pipe body 1, and a connecting rod 21 that extends along the length direction of the pipe body 1 and is arranged in the pipe body 1, and the two plugs 20 pass through the pipe body 1 through the connecting rod 21 and pass out to the two ends of the two openings to be locked. In the prior art, for example, in the construction of reinforced concrete walls, underground engineering exterior walls, etc., it is often necessary to pre-buried pipes for later pipe threading, and the blocking of pre-buried pipes on site is often relatively simple, and most of them are directly used to stuff filler materials, plastics and other debris into the openings. After a long time, concrete will enter the pipe and cause corrosion in the pipe, which will cause difficulties in later pipe threading. The present application adopts a simple structure for blocking, and the cost is not high, but it can achieve a good blocking effect. Specifically, two plugs 20 are used to respectively block the two openings of the embedded pipe, and then a connecting rod 21 is used to position and lock the two plugs 20 to prevent them from being moved by external forces such as squeezing to affect the blocking effect. The connecting rod 21 is in a long strip shape, which is almost the same length as the embedded pipe to be blocked and can pass through the embedded pipe along the embedded pipe, and then its two ends are connected to the plugs 20 to limit the two plugs 20. The blocking structure is simple and easy to implement, and the size can be matched according to the size of the embedded pipe used, which can achieve a good blocking effect.

[0018] The following are specific embodiments:

[0019] As an optimization solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 , both ends of the connecting rod 21 pass through the two plugs 20, and the end of the connecting rod 21 passing through the plugs 20 is threadedly connected with a nut 22. In this embodiment, in order to enable the connecting rod 21 to better lock and position the two plugs 20, a nut 22 is provided at the end of the connecting rod 21 passing through the plugs 20 to more stably lock the plugs 20. Preferably, a rubber gasket 23 is sleeved on the end of the connecting rod 21 passing through the plugs 20, and the nut 22 presses the rubber gasket 23 to strengthen the locking degree of the nut 22.

[0020] As an optimization solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 The blocking structure further includes a blocking member for blocking the plug 20 from moving toward the other plug 20. In this embodiment, when the connecting rod 21 positions and locks the two plugs 20, if the pulling force is too large, the plug 20 may be pulled into the tube body 1, so the blocking member can effectively prevent this from happening.

[0021] To further optimize the above solution, please refer to Figure 1 and Figure 2 , the blocking member includes a gasket 24 placed in the tube body 1 and fixedly connected to the inner wall of the tube body 1, and the connecting rod 21 passes through the gasket 24 to the plug 20. In this embodiment, the blocking member is an annular gasket 24, which is placed in the tube body 1 and fixedly connected to the inner wall of the tube body 1. The fixing method can be adhesive bonding, or other methods such as screws, buckles, etc. After it is fixed in the tube body 1, it has a certain thickness, so it can resist the plug 20 to prevent the plug 20 from entering the tube body 1. Of course, in addition to using the gasket 24, other forms of blocking methods are also possible, such as a blocking block. The blocking block can be embedded in the tube wall, leaving only a small part to block the plug 20 to ensure integrity. There are many ways to achieve this, and I will not give examples one by one here.

[0022] As an optimization solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 The embedded pipe also includes a reinforcing structure 3 that can be anchored to the engineering wall, and the reinforcing structure 3 is arranged on the pipe body 1. In the prior art, since the pipe body 1 is embedded in the concrete wall, the pipe body 1 can be fixed in the wall after the concrete solidifies. However, the pipe body 1 is only a cylindrical structure after all, and its surface is mostly smooth, so it may fall off after a long time. Therefore, this embodiment adopts the reinforcing structure 3 to strengthen the anchoring of the embedded pipe and the engineering wall to prevent the above situation from happening.

[0023] To further optimize the above solution, please refer to Figure 1 and Figure 2 The reinforcement structure 3 includes a reinforcement block 30 fixed on the pipe body 1 and a reinforcement member 31 anchored in the engineering wall, and the reinforcement member 31 is rotatably connected to the reinforcement block 30. In this embodiment, the reinforcement member 31 is rotatably connected to the reinforcement block 30, and the most suitable anchoring angle can be found for the reinforcement member 31 according to the actual pre-embedded situation. There are many ways to fix the reinforcement block 30 on the pipe body 1. In this embodiment, the preferred pipe body 1 is a galvanized steel pipe, and the material of the reinforcement member 31 is preferably steel, which has strong corrosion resistance. If a galvanized steel pipe is used, the fixing method can be welding to make it more firm. Of course, other existing fixing methods can be used, and this embodiment does not limit this.

[0024] To further optimize the above solution, please refer to Figure 1 and Figure 2The reinforcement 31 is in the shape of a pull ring, and the pull ring-shaped reinforcement 31 has two hook ends 310 facing each other. The reinforcement block 30 has two grooves 300 for the two hook ends 310 to be respectively inserted into, and the hook ends 310 are rotatably arranged in the corresponding grooves 300. In this embodiment, the rotation form is specifically the form in which the hook ends 310 of the reinforcement 31 rotate in the grooves 300 of the reinforcement block 30. The reinforcement 31 is similar to a pull ring, which can increase the range of anchoring. Preferably, the rotation angle is preferably 90°, that is, rotating from the vertical direction to the horizontal direction. The reinforcements 31 of the two reinforcement groups rotate in different directions, which can achieve a better anchoring effect. Figure 1 The dotted line at the middle reinforcement member 31 is a schematic diagram of the rotation of the reinforcement member 31.

[0025] As an optimization solution of the embodiment of the present invention, please refer to Figure 1 and Figure 2 , the number of the reinforcing structures 3 is multiple, and the multiple reinforcing structures 3 are arranged around the tube body 1. In this embodiment, the number of the reinforcing structures 3 is multiple and they are arranged around the tube body 1 to further enhance the anchoring effect. Preferably, the number of the reinforcing structures 3 is four, which is evenly distributed around the cylindrical tube body 1, which can ensure uniform force.

[0026] To further optimize the above solution, please refer to Figure 1 and Figure 2 , a plurality of the reinforcement structures 3 form a reinforcement group, and the number of the reinforcement groups is multiple, and each reinforcement group is arranged at intervals along the length direction of the pipe body 1. In this embodiment, there are multiple reinforcement groups, which can ensure that the anchoring of the entire pipe body 1 can be strengthened.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
