[0033] Example 1

[0034] Combined with Figure 1-4 , this embodiment provides a connection structure, including:

[0035] A first sleeve 1, both sides of the first sleeve 1 are provided with a plurality of locking joints 3;

[0036] A second sleeve 2 matched with the first sleeve 1, with a plurality of pin holes 4 on both sides of the second sleeve 2;

[0037] Among them, the locking connector 3 and the latch opening 4 cooperate with each other.

[0038] Specifically, when the connection structure is connected, the first sleeve 1 and the second sleeve 2 are first matched, so that the multiple locking joints 3 and the multiple pin holes 4 are aligned. When the connection structure is used for prefabricated underground continuous walls, it is convenient to make the alignment performance of adjacent prefabricated underground continuous walls good and not prone to misalignment. At the same time, the shear resistance of adjacent prefabricated underground continuous walls is good. Then, under the action of the self-weight of the first sleeve 1 and the multiple locking joints 3, the multiple locking joints 3 and the multiple pin holes 4 are matched. When the connection structure is used for prefabricated underground continuous walls, it is convenient to make the connection speed of adjacent prefabricated underground continuous walls fast; wherein, the material of the first sleeve 1 and the second sleeve 2 can both be steel.

[0039] Further, such as Figure 2 The first sleeve 1 is sleeved inside the second sleeve 2 , or the first sleeve 1 is sleeved outside the second sleeve 2 .

[0040] Specifically, when the first sleeve 1 is sleeved inside the second sleeve 2, the caliber of the first sleeve 1 is relatively small; when the first sleeve 1 is sleeved outside the second sleeve 2, the caliber of the second sleeve 2 is relatively small.

[0041] Further, such as Figure 2 , and also includes a filler 5, which is filled in the first sleeve 1 or the second sleeve 2.

[0042] Specifically, the filler 5 is used to fill in a sleeve with a relatively small diameter. When the first sleeve 1 is sleeved in the second sleeve 2, the filler 5 is filled in the first sleeve 1. When the first sleeve 1 is sleeved outside the second sleeve 2, the filler 5 is filled in the second sleeve 2. The filler 5 can be a high-strength, non-shrinkage cement-based grouting material, etc. It should be noted that after the first sleeve 1 and the second sleeve 2 are fully matched, the filler 5 is poured into the first sleeve 1 or the second sleeve 2 to increase the strength of the first sleeve 1 or the second sleeve 2.

[0043] Further, such as Figure 4 ,

[0044] The locking joint 3 comprises a joint body 31, a first groove portion 32 and a first protrusion portion 33 which are arranged in sequence;

[0046] The first groove portion 32 cooperates with the second protrusion portion 43 , and the second groove portion 42 cooperates with the first protrusion portion 33 .

[0047] Specifically, since the first groove portion 32 and the second protrusion portion 43 cooperate with each other, and the second groove portion 42 and the first protrusion portion 33 cooperate with each other, the locking connector 3 and the latch port 4 can be snapped into place, which not only makes the connection speed of the locking connector 3 and the latch port 4 fast, but also prevents the locking connector 3 and the latch port 4 from separating.

[0048] Further, such as Figure 2 The locking joints 3 on both sides of the first sleeve 1 are arranged axially symmetrically with respect to the first sleeve 1 , and the latch openings 4 on both sides of the second sleeve 2 are arranged axially symmetrically with respect to the second sleeve 2 .

[0049] Specifically, it is convenient to increase the symmetry of a plurality of locking joints 3 and at the same time, it is convenient to increase the symmetry of a plurality of latch openings 4 .

[0050] Example 2

[0051] Combined with Figure 1-4 The present embodiment provides a prefabricated underground continuous wall, including a connection structure of embodiment 1, and also including a first wall 6 and a second wall 7 that cooperate with each other, a first sleeve 1 and a plurality of locking joints 3 are connected to the first wall 6, and a second sleeve 2 and a plurality of pin holes 4 are connected to the second wall 7.

[0052] Specifically, the first wall 6 is used as an upper segmented wall; the second wall 7 is used as a lower segmented wall.

[0056] Specifically, the first stress-bearing steel bar 81 is used to increase the connection firmness between the locking joint 3 and the first wall 6 ; the second stress-bearing steel bar 82 is used to increase the connection firmness between the latch opening 4 and the second wall 7 .

[0057] Further, such as Figure 3 , also includes:

[0058] A first anti-shear portion 91 provided at one end of the first wall 6;

[0059] A second anti-shear portion 92 provided at one end of the second wall 7;

[0060] Among them, one of the first anti-shear portion 91 and the second anti-shear portion 92 is a convex portion, and the other is a concave portion, and the convex portion and the concave portion cooperate with each other.

[0061] Specifically, the first anti-shear portion 91 and the second anti-shear portion 92 are used to increase the shear resistance of the first wall 6 and the second wall 7. When the first anti-shear portion 91 is a convex portion, the second anti-shear portion 92 is a concave portion; when the first anti-shear portion 91 is a concave portion, the second anti-shear portion 92 is a convex portion.
