[0025] Embodiment

[0026] Please refer to Figure 1-Figure 2 , this embodiment provides a casting mold for precast concrete drainage ditches, which includes an outer mold and an inner mold. The outer mold includes two outer mold templates 1 with an L-shaped cross-section. The two outer mold templates 1 are detachably connected, and the two outer mold templates 1 are connected to form a "U" shape; the inner mold includes two inner mold templates 2 with an L-shaped cross-section. The inner mold templates 2 are located inside the outer mold, and a "U"-shaped casting chamber 4 is formed between the inner mold and the outer mold; the inner sides of the two inner mold templates 2 are rotatably connected to each other, and inner mold fixing plates 3 are provided on the outer sides of the two inner mold templates 2. The inner mold fixing plates 3 are detachably connected to the outer mold templates 1.

[0027] Both of the two outer mold templates 1 are provided with first connecting plates 5, and the two first connecting plates 5 are detachably connected by a first bolt 6. The outer mold template 1 is provided with a second connecting plate 7, and the inner mold fixing plate 3 and the second connecting plate 7 are detachably connected by a second bolt 8. The inner sides of the two inner mold templates 2 are rotatably connected by a plurality of hinges 9.

[0028] During actual use, as Figure 1 shown, fix the two outer mold templates 1 with the first bolt 6, place the two inner mold templates 2 inside the outer mold, and after adjusting the positions of the two inner mold templates 2 by rotating along the hinges 9, fix the inner mold fixing plate 3 and the second connecting plate 7 with the second bolt 8. At this time, the outer mold and the inner mold are fixedly installed with each other, and there is a "U"-shaped casting chamber 4 in the middle. Vertically place the casting mold for precast concrete drainage ditches provided by this application on the cement floor as Figure 1 shown. The mold is upright. Place the tied steel bar skeleton in the casting chamber 4 and pad the protective layer cushion blocks, and then pour concrete into the casting chamber 4, vibrate and finish the surface to form. After solidification, demold. When demolding, remove the second bolt 8 and rotate the two inner mold templates 2 inward. When the two inner mold templates 2 rotate along the hinges 9, it is convenient to demold the inner side wall of the inner mold template 2 from the cast drainage ditch; after the inner mold is demolded, remove the first bolt 6 and demold the two outer mold templates 1 from the outer side wall of the cast drainage ditch.

[0029] The advantages of this application compared with traditional templates are:

[0030] 1. It is economical and convenient for construction. The formwork can be disassembled and assembled quickly, enabling fast formwork turnover. (For traditional formwork, flat pouring requires secondary pouring. It is difficult to control geometric dimensions, formwork erection is cumbersome, and high concrete strength is required during hoisting, necessitating the addition of a bottom formwork.).

[0031] 2. It has high practicality and is convenient for ramming concrete during pouring. (When using traditional molds for pouring, it is impossible to vibrate the bottom of the "U"-shaped mold using the ramming type vibrator, and it is difficult to set the lifting points.).

[0032] The concrete precast gutter pouring mold provided by this application adopts the vertical pouring method, which can form a "U"-shaped drainage gutter in one-time pouring without the need for secondary pouring, improving construction efficiency; the steel bar protective layer is easy to control, and it is convenient for concrete to be poured into the mold and vibrated. Secondary hoisting can be used for centralized curing to save the pouring site, accelerate the turnover times, ensure the curing effect, and improve the concrete quality.

[0033] As Figure 1-Figure 2 shown, in some embodiments of the present utility model, a fixing strip 10 is provided between two inner mold fixing plates 3, and the fixing strip 10 is detachably connected to the two inner mold fixing plates 3 respectively. The inner mold fixing plate 3 is provided with a third connecting plate 11, and the fixing strip 10 and the third connecting plate 11 are detachably connected by a third bolt 12.

[0034] By setting the fixing strip 10 in the present utility model, after the outer mold and the inner mold are installed, the fixing strip 10 can be fixed between the two inner mold fixing plates 3 through the third bolt 12, improving the stability of the inner mold fixing.

[0035] As Figure 1-Figure 2 shown, in some embodiments of the present utility model, hooks 13 are provided on both inner mold fixing plates 3.

[0036] By setting the hooks 13 in the present utility model, when demolding the inner mold, a rope can be hung on the hooks 13 to pull the inner mold fixing plate 3 and the inner mold template 2 to rotate together along the hinge 9, reducing the operation difficulty.

[0037] As Figure 1-Figure 2 shown, in some embodiments of the present utility model, it further includes an inserted PVC pipe 14. Both the outer mold template 1 and the inner mold template 2 are provided with insertion holes 15, and the inserted PVC pipe 14 passes through the insertion holes 15.

[0038] By setting the inserted PVC pipe 14 in the present utility model, before pouring concrete, the inserted PVC pipe 14 can be inserted into the insertion holes 15, and the inserted PVC pipe 14 passes through the insertion holes 15. After pouring concrete, when the concrete begins to set, the inserted PVC pipe 14 is pulled out and the geotextile is covered and watered for curing. In this way, hoisting holes can be reserved on the precast gutter produced, facilitating the subsequent hoisting of the precast gutter.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.

[0040] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved. For those skilled in the art, the utility model can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
