It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] See Figures 1 to 3 The figure illustrates a preferred structure of the flexible assembly prefabricated pipe gallery template provided by an embodiment of the present invention. As shown, the flexible assembly prefabricated pipe gallery template includes: an inner mold 1 and an outer mold 2 fitted around the outer periphery of the inner mold 1; both the inner mold 1 and the outer mold 2 include four corner templates 11 and at least four panel templates 12; wherein, Four corner templates 11 are respectively set at the four corners of the rectangular structure, and at least one panel template 12 is provided between any two adjacent corner templates 11. The four corner templates 11 and at least four panel templates 12 are assembled to form a rectangular template structure.

[0018] Specifically, both the inner mold 1 and the outer mold 2 are detachable rectangular template structures, assembled from four corner templates 11 and a panel template 12. In this embodiment, the panel template 12 has various widths, with the width of different panel template 12 increasing according to the same modular increment, meaning the panel template 12 has multiple standard widths. These standard widths are based on a basic module W, and the widths of different panel templates 12 are positive integer multiples of the basic module W. The basic module W ranges from 50mm to 300mm, preferably 100mm. In this embodiment, to improve the strength and stability of the precast pipe gallery template, preferably, each corner template 11 and each panel template 12 of the inner mold 1 is provided with internal stiffening ribs 3; each corner template 11 and each panel template 12 of the outer mold 2 is provided with external stiffening ribs 4, and the internal and external stiffening ribs 4 can be arranged horizontally and vertically in a crisscross pattern. In this embodiment, the number of corresponding side panel templates 12 of the inner mold 1 and the outer mold 2 is the same, and each corner template 11 of the inner mold 1 corresponds one-to-one with each corner template 11 of the outer mold 2, and each panel template 12 of the inner mold 1 corresponds one-to-one with each panel template 12 of the outer mold 2, as shown below. Figure 3As shown, this embodiment uses one plate template 12 for both the inner and outer molds 2 on the horizontal side and two plate templates 12 for both the inner and outer molds 2 on the vertical side as an example. Of course, other embodiments may use other quantities, and this embodiment does not impose any limitations on them. To facilitate the hoisting of each part, preferably, each corner template 11 and each plate template 12 may be provided with a lifting lug 6 at its top.

[0019] See also Figure 2 and Figure 3 The corner template 11 may include two vertically arranged template bodies 111 connected to each other. Specifically, the two template bodies 111 are arranged vertically and form a corner structure. The two template bodies 111 can be an integral structure, such as by bending or other integral forming methods, and this embodiment does not impose any limitations on it.

[0020] In this embodiment, any adjacent corner templates 11 and panel templates 12 in the inner mold 1 and / or outer mold 2 are detachably connected. Specifically, any adjacent corner templates 11 and panel templates 12 in the inner mold 1 and / or outer mold 2 are connected by threaded rods 13. Of course, two adjacent panel templates 12 can also be connected by threaded rods 13. Each corner template 11 and panel template 12 has a connecting plate 14 extending along the thickness direction along its height direction on its side. The connecting plates 14 on the sides of any adjacent corner template 11 and panel template 12 are in abutting contact with each other. The connecting plate 14 has a mounting hole, and the threaded rod 13 passes through the mounting hole to realize the detachable connection between the corner template 11 and the panel template 12. The connection method between the panel templates 12 can refer to the connection method between the corner templates 11 and the panel template 12, which will not be described in detail in this embodiment.

[0021] In this embodiment, the inner mold 1 and the outer mold 2 are detachably connected by connectors 5. Specifically, each corner template 11 of the inner mold 1 is detachably connected to its corresponding corner template 11 of the outer mold 2, and in particular, they are all detachably connected by connectors 5. The connectors 5 can be tie bolts or other similar connectors, and this embodiment does not impose any limitations on them. Preferably, each corresponding template body 111 can also be detachably connected by connectors 5. Of course, each panel template 12 of the inner mold 1 is detachably connected to its corresponding panel template 12 of the outer mold 2.

[0022] In this embodiment, the heights of the corner template 11 and the panel template 12 are both 2m and 2.5m.

[0023] In actual construction, the corner formwork 11 and the slab formwork 12 can be reasonably combined to form an inner mold 1 and outer mold 2 system that conforms to the cross-sectional dimensions of the segmented precast pipe gallery to be produced. The corner formwork 11 and the slab formwork 12 are connected by threaded rods 13 behind the formwork to form an integral precast pipe gallery formwork. Then, the steel bars are tied and the concrete is poured to form a segmented precast pipe gallery.

[0024] In summary, the flexible assembly precast pipe gallery template provided in this embodiment decomposes the integral inner mold 1 and outer mold 2 into a combination template of corner template 11 and panel template 12. According to the size of the segmental precast pipe gallery, segmental precast pipe galleries of different sizes can be produced by flexibly combining panel templates 12 of different widths with corner templates 11. This template increases the secondary use rate of the template without affecting the construction speed and quality, improves the turnover efficiency, reduces the one-time investment cost of the fixed template, saves the production cost of segmental precast pipe galleries, and solves the problem that the existing integral inner mold and outer mold 2 for segmental precast pipe galleries cannot produce precast pipe gallery sections with other cross-sectional sizes.
