DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, a three-hole concrete water-stop curtain pile foundation unit provided in this embodiment includes a first concrete fixing pile 101 and a second concrete fixing pile 104. The diameters of the first concrete fixing pile 101 and the second concrete fixing pile 104 are equal. The second concrete fixing pile 104 is filled with a steel cage. The first concrete fixing pile 101 is provided with two first conduit holes 102 arranged opposite to each other. The second conduit hole 103 is a circular hole. The second conduit hole 103 is coaxially arranged with the first concrete fixing pile 101. During construction, a second concrete fixing pile 104 is arranged between every two first concrete fixing piles 101. The steel cage arranged in the second concrete fixing pile 104 can greatly increase the strength of the utility model after construction.

[0023] A second conduit hole 103 is provided on the first concrete fixing pile 101, and a fixing groove 105 is provided on the first concrete fixing pile 101. The fixing groove 105 is arranged correspondingly with the second conduit hole 103. After the first concrete fixing pile 101 is cast, a conduit for plasticizing the first conduit hole 102 and the second conduit hole 103 is inserted. After the concrete fixing pile is solidified, the conduits in the first conduit hole 102 and the second conduit hole 103 are pulled out by a corresponding pile pulling machine. The second conduit hole 103 is used to install the monitoring device 200. The first conduit hole 102 can facilitate the drilling operation before the casting of the second concrete fixing pile 104, and the part of the first concrete fixing pile 101 whose edge is broken by the drilling step can increase the casting strength of the second concrete.

[0024] The second conduit hole 103 is fixedly provided with a fixed cover plate 106, and a connecting steel pipe 108 is installed on the fixed cover plate 106. The connecting steel pipe 108 is divided into several sections, and several monitoring devices 200 are installed between two adjacent connecting steel pipes 108. The monitoring devices 200 are located in the second conduit hole 103. The connecting steel pipe 108 is hollow. In this embodiment, the connecting steel pipe 108 is used to install the line, but the connecting steel pipe 108 can also be used to install the air pipe to discharge the moisture in the housing 201. The mounting seat 204 is connected to the connection below it through the connecting pipe 206. The steel pipe 108 is connected, and the lower end of the lowest connecting steel pipe 108 is cooperated with the installation cone 107. The diameters of the outer shell 201 and the installation cone 107 are smaller than the inner diameter of the second catheter hole 103. In this embodiment, the difference between the diameters of the outer shell 201 and the installation cone 107 is 5 mm. The setting of the difference can prevent the outer shell 201 from being stuck in the second catheter hole 103 when the monitoring device 200 is installed. The installation cone 107 can grind the inside of the second catheter hole 103 once to prevent the second catheter hole 103 from wearing out the outer shell 201 when the monitoring device 200 is installed.

[0025] The monitoring device 200 includes a shell 201, which is slidably matched with the second conduit hole 103. A connecting frame 202 is fixedly installed on the lower side of the shell 201, and the upper side of the shell 201 and the lower side of the connecting frame 202 are fixedly connected to the connecting steel pipe 108. The shell 201 is in the shape of an inverted bowl, and a mounting seat 204 is installed in the shell 201. A humidity sensor 205 is installed on the mounting seat 204. The inverted bowl-shaped shell 201 can better capture moisture and obtain more accurate humidity data, which greatly increases the accuracy of the data. In this embodiment, concrete can be poured into the second conduit hole 103 before the installation of the monitoring device 200, and then the monitoring device 200 in the embodiment can be inserted. The inverted bowl-shaped shell 201 can prevent the poured concrete from entering the interior of the shell 201, and the overall structural strength can be improved after pouring.

[0026] It should be noted that, during the construction of the utility model, firstly, two minimum installation holes are punched out by a rotary drilling machine of a single pile, and these two installation holes are used for pouring the first concrete fixed pile 101. After the drilling is completed, a water pump is used to extract the mud in the hole and pour concrete. Before it solidifies, a pad is placed on the hole, and three conduits are inserted into the pad. After the concrete solidifies, the construction pile pulling machine pulls out the three conduits to form three eyes, two of which are two first conduit holes 102 arranged opposite to each other, and the central one is the second conduit hole 103. Then, a hole is punched out between two adjacent first concrete fixed piles 101 using a rotary drilling machine, and this hole should include the two adjacent first conduit holes 102 within its range (refer to Figure 2), the edge of the first concrete fixing pile 101 is broken by the drilling step. The part of the first concrete fixing pile 101 that is broken can increase the pouring strength of the second concrete. After the drilling is completed, pumping is carried out in turn to prevent the steel cage and concrete pouring. After the first concrete fixing pile 101 and the second concrete fixing pile 104 are solidified, the monitoring device 200 can be installed. The monitoring device 200 is connected through the connecting steel pipe 108 and inserted into the second conduit hole 103. The second conduit hole 103 is sealed by the fixed cover plate 106 to prevent the outside from interfering with the index of the humidity sensor 205. The installation of the utility model with barbs is completed. The utility model can monitor the humidity condition in the water-stop curtain through the monitoring device 200, and can timely discover and prevent the water-stop curtain from being damaged and causing water seepage, and can carry out emergency repairs in advance, saving a lot of manpower and materials. force, reducing the possible safety threats during the construction process, and the housing 201 of the monitoring device 200 is in an inverted bowl shape, which can better capture moisture, obtain more accurate data, and improve the authenticity of the data. The monitoring device 200 of the utility model can also pre-pour concrete into the second conduit hole 103 before the installation of the monitoring device 200, and then insert the monitoring device 200 into the poured concrete. The inverted bowl-shaped housing 201 design cleverly prevents the subsequently poured concrete from penetrating into the housing 201, thereby ensuring the integrity of the internal components of the device and preventing damage caused by direct contact between the humidity sensor 205 and the concrete. This design not only simplifies the installation process, but also further enhances the overall structural strength after pouring without weakening the overall structural strength, providing a strong guarantee for the stability and safety of the project.
