[0023] like Figure 1-6 As shown, a pre-buried structure of an orifice pipe for freezing construction includes an underground wall 1, an orifice pipe 3 and a freezing pipe 4. An installation hole is provided on the underground wall 1, and the orifice pipe 3 is installed in the installation hole and one end of the orifice pipe 3 extends out of the underground wall 1. Concrete is poured on the outside of the underground wall 1 to form a wall 2, and the wall 2 covers the orifice pipe 3. When pouring the wall 2, a fixing plate 31 is provided on one end of the orifice pipe 3 located on the underground wall 1, and the fixing plate 31 is supported on the outer wall of the underground wall 1, and the orifice pipe 3 is pre-fixed by the fixing plate 31.

[0024] A clamping structure is provided on the inner wall of the orifice pipe 3 and the outer wall of the freezing pipe 4, and the freezing pipe 4 is detachably installed in the orifice pipe 3 through the clamping structure. Specifically, the clamping structure includes an L-shaped clamping groove 32 provided on the inner wall of the orifice pipe 3 and a clamping column 41 provided on the outer wall of the freezing pipe 4, and the freezing pipe 4 and the orifice pipe 3 are installed by clamping the clamping column 41 on the L-shaped clamping groove 32.

[0025] The above-mentioned structure is used to realize the setting of the embedded structure. The structure pre-sets the orifice pipe 3 in the underground wall 1 and the wall 2, and then installs the freezing pipe 4 through the orifice pipe 3. There is no need to drill holes on the wall 2 at a later stage, thereby avoiding damage to the underground wall 1 or the wall 2 when installing the freezing pipe 4, thereby protecting the integrity of the underground wall 1 and the wall 2.

[0026] Furthermore, when installing the orifice pipe 3, a waterproof hose is sleeved on the outer wall of the orifice pipe 3, and then before the wall 2 is cast, a first water retaining ring 33 is sleeved on the outer wall of the waterproof hose, so that the first water retaining ring 33 is located between the underground wall 1 and the wall 2. After the wall 2 is cast, a second water retaining ring 34 is sleeved on the outer wall of the waterproof hose, and the second water retaining ring 34 is tightly attached to the wall 2. Through this structure, the waterproof sealing between the orifice pipe 3 and the underground wall 1 and the wall 2 can be effectively improved.

[0027] Furthermore, a connecting ring 5 is included. A sealing ring 51 and an internal thread are provided on the connecting ring 5, and an external thread is provided on the outer wall of the freezing pipe 4 on one side of the wall 2. The connecting ring 5 is installed on the freezing pipe 4 through the internal and external threads, and the sealing ring 51 is located between the freezing pipe 4 and the orifice pipe 3. Through this structure, the waterproof sealing between the freezing pipe 4 and the wall 2 can be effectively improved.

[0028] Furthermore, it also includes a locking plate 6 and a locking nut 61. The locking plate 6 is sleeved on the freezing pipe 4 and is tightly attached to the outer wall of the wall 2. The locking nut 61 is installed on the freezing pipe 4 through the external thread of the freezing pipe 4 and presses on the locking plate 6. This structure can strengthen the fixation of the freezing pipe 4 to the end of the wall 2.

[0029] Furthermore, it also includes a sealing plug 7, a connecting rod 71 and a sealing plug head 72 connected in sequence, the sealing plug 7 is inserted in the freezing pipe 4, the sealing plug head 72 is inserted in the end of the freezing pipe 4 on one side of the wall 2, and a clamping plate 73 is provided on the sealing plug head 72, and a ball 74 is provided on the clamping plate 73, and the ball 74 is in close contact with the inner wall of the freezing pipe 4. The sealing plug 7 is used to seal the inside of the freezing pipe 4. When the freezing method construction is required, the sealing plug 7 needs to be pulled out and a low-temperature liquid is injected into the freezing pipe 4, so that the underground wall 1 can be frozen. The sealing plug head 72 is used to drive the sealing plug 7 to be plugged in and out, and the ball 74 is used to improve the smoothness of the plug head 72 when plugging and pulling out.
