Example one

In this embodiment, as shown in fig. 1, the mold assembly is mainly used for forming a female splicing end 101 of a concrete pile wall 100, where the female splicing end 101 is defined as an end where a recess is formed in the concrete pile wall 100, the concrete pile wall 100 can be prefabricated and formed in a factory in advance, the female splicing end 101 and/or the male splicing end 102 are formed at the end portions connected to each other, and when adjacent concrete pile walls 100 are spliced, the male splicing end 102 is inserted into the female splicing end 101, so as to ensure accurate positioning of the concrete pile wall 100 without deviation and affecting the construction progress, and to improve the connection effect between the adjacent concrete pile walls 100, and to enhance the sealing effect between the adjacent concrete pile walls 100 by injecting concrete or sealing material after the adjacent concrete pile walls 100 are connected, so that the premixed concrete pile wall 100 can be used to replace an underground diaphragm wall, thereby avoiding high operation cost of the underground diaphragm wall and difficult problem of waste slurry treatment on a construction site during urban operation .

In order to ensure the molding quality of the female splicing end 101 of the molded concrete pile wall 100 and ensure smooth demolding after the molding of the concrete pile wall 100, as shown in fig. 2, the mold assembly comprises: at least one first template 1 with a deformation resetting function, wherein the first template 1 is at least adapted to the end profile of the female splicing end 101 forming a recess in the thickness direction of the concrete pile wall 100, and a second template 2 is used for supporting the first template 1 and adapting to the rest end profile of the female splicing end 101, and at least one end of the first template can enter and exit the female splicing end 101, wherein a bulge 11 deviating from the second template 2 in the thickness direction of the concrete pile wall 100 is formed at a position of the forming surface of the first template 1 at a preset distance from the end surface of the female splicing end 101, so that when the concrete pile wall 100 is prefabricated, the first template 1 and the second template 2 are matched to form the complete end profile of the female splicing end 101, after the concrete pile wall 100 is formed, the first template 1 is demoulded by using the deformation resetting function, and the so-called deformation resetting function can be understood as an elastic structure, such as springs and rubber, which are deformed under the action of a certain external force, and the structural shape of the concrete pile wall 100 is restored after the external force is removed, thereby improving the forming quality and the demoulding efficiency of the concrete pile wall.

As can be seen from the above, the molding surface of the first form 1 forms at least a predetermined distance from the end surface of the female splice end 101 a protrusion 11 that faces away from the second form 2 in the thickness direction of the concrete pile wall 100.

After the concrete pile wall 100 is formed, the first template 1 enters and exits the female splicing end 101 together along with the second template 2, for example, the second template 2 is pulled, the first template 1 is deformed by a certain pulling force, and then the first template 1 and the second template 2 are separated from the concrete pile wall 100 together, so that the demolding is completed, the complexity of mold assembly is reduced, the mold assembly is convenient to disassemble and install, and the demolding efficiency and the construction efficiency are improved. The other is, as shown in fig. 2, the first template 1 and the second template 2 can be fixed by one or a combination of screw joint, clamping joint, pin joint, insertion, lap joint and magnetic attraction connection, and can be disassembled and installed, after the concrete pile wall is prefabricated and formed, the second template 2 is firstly disassembled from the first template 1, then the first template 1 is separated from the concrete pile wall 100, and the demolding can be completed, so that the demolding is more convenient on the premise of ensuring the molding quality of the concrete pile wall.

In this embodiment, as shown in fig. 2, an upper convex section 13 is further disposed at an end of the first form 1 away from the protrusion 11, wherein a groove adapted to the upper convex section 13 is disposed on the first molding surface 22 of the second form 2, and the upper convex section 13 and the groove adapted thereto may be screwed together, or the upper convex section 13 and the groove may be clamped together, so as to ensure the connection reliability between the first form 1 and the second form 2.
