In addition, a boss 64 protruding toward the cavity 3 may be formed at the end of the protruding portion 6 facing the cavity 3, so that the formed grouting groove 102 may have a step transition structure, and the connection strength between the two precast pile walls 100 may be strengthened after the two precast pile walls are spliced. And if the water stop plate is installed in the grouting groove 102, the groove formed by the boss 64 can play a role in positioning the water stop plate, so that the operation of construction operation is facilitated.
In the modification of this embodiment, the protruding portion 6 and the side die assembly may be designed as an integral structure, or the protruding portion 6 and the side die assembly may be detachably positioned by the fastening member 63, so as to facilitate the installation and detachment of the fastening member 63 and provide a certain working space for an operator, the fastening member receiving groove 7 is designed at a connection position of the first side die plate 1 and/or the second side die plate 2 of the side die assembly and the protruding portion 6, the depth and the width of the receiving groove 7 may be determined according to the size requirement of the working space and the strength requirement of the first side die plate 1 and the second side die plate 2, and this embodiment does not specifically limit this.
In other variations of this embodiment, the first side formwork 1 and/or the second side formwork 2 are disposed in an inclined manner on a side away from the mold cavity 3, or a side of the first side formwork 1 and/or the second side formwork 2 away from the mold cavity 3 is designed with a mold drawing wedge having an inclined surface, so that the inclined surface can be used to facilitate the installation and the disassembly of the side formwork assembly, especially after the prefabricated pile wall 100 is formed, the inclined surface can be used to facilitate the detachment of the heavy prefabricated pile wall 100 from the mold, and the improvement in production efficiency is significant.

In this embodiment, the precast pile wall forming mold is in a ground mold structure, that is, the forming mold includes an outer mold frame 9 with a flat bottom surface, and the side mold assemblies are disposed in the outer mold frame 9, so that the first side mold plate 1 and the second side mold plate 2 of the side mold assemblies can be combined with the outer mold frame 9 to form the mold cavity 3 of the open-mouthed formed precast pile wall 100. After the concrete poured into the cavity 3 is solidified to form the precast pile wall 100, the first side formworks 1 and the second side formworks 2 are separated from the outer formwork 9 in the up-down direction shown in fig. 5 to complete the demolding. The advantage of adopting this kind of structural style is that it can set up two or more forming die side by side along transversely and form the mould group, as shown in fig. 6, so can improve the production efficiency of precast pile wall 100 and to the space utilization who produces the factory building, and then provide the advantage on precast pile wall 100's manufacturing cost and market competition.
In the modification of the embodiment, the side 91 of the outer frame 9 of the adjacent forming mold of the precast pile wall forming mold set formed by at least two forming molds arranged along the width direction of the precast pile wall 100 is tightly attached to each other, so as to reduce the occupation of the factory space. Or, in another variation, the outer frames 9 of adjacent forming molds may share the same side 91, so that the space utilization rate of the factory building is further improved, the material consumption for manufacturing the molds can be reduced, and the cost control advantage is obvious.
As shown in fig. 7 and 8, the precast pile wall 100 manufactured in this embodiment may have a cavity 101, and accordingly, as shown in fig. 2, the forming mold of this embodiment may have a core mold 40, and particularly, the core mold 40 may be positioned by tension members or fixed end plates 30 at both ends thereof, and the cavity 101 formed by the core mold 40 may reduce the amount of concrete used for the precast pile wall 100, thereby reducing the manufacturing cost thereof and improving the market competitiveness thereof.
