Detailed implementation mode

[0033] The following will further elaborate on this application in conjunction with the Figures 1-5 accompanying drawings.

[0034] The embodiment of this application discloses a jacking pipe casting mold.

[0035] Embodiment 1

[0036] Referring to Figure 1 , a jacking pipe casting mold includes two half pipes 100. The two half pipes 100 can be connected into a whole pipe through a number of bolts. A rubber pad is arranged at the butt joint of the two half pipes 100, and the rubber pad increases the sealing performance after the two half pipes 100 are butted.

[0037] A plurality of support cross beams 110 are fixedly connected to the circumferential surface of each half pipe 100. Each support cross beam 110 is fixedly attached to the circumferential surface of the half pipe 100. The plurality of support cross beams 110 are arranged at intervals along the length direction of the half pipe 100. A plurality of support longitudinal beams 120 are fixedly connected to the circumferential surface of each half pipe 100. Each support longitudinal beam 120 is parallel to the length direction of the half pipe 100. The plurality of support longitudinal beams 120 are arranged at intervals along the circumferential surface of the half pipe 100. The plurality of support longitudinal beams 120 and the plurality of support cross beams 110 are arranged in a staggered manner and fixedly connected together. Using the plurality of support longitudinal beams 120 and the plurality of support cross beams 110 to jointly support the half pipe 100 can significantly increase the strength of the casting mold and reduce the possibility of deformation of the jacking pipe during the casting process of the jacking pipe.

[0038] Referring to Figure 1 , at least two vibration motors 200 are fixedly connected to each half pipe 100. In this embodiment, two vibration motors 200 are fixedly connected to each half pipe 100. During the process of pouring slurry into the casting mold composed of the two half pipes 100, a plurality of vibration motors 200 are started simultaneously, and the slurry in the casting mold is vibrated and compacted by the vibration of the plurality of vibration motors 200 to ensure the strength of the jacking pipe.

[0039] Referring to Figure 1 and Figure 2, at the top of each half pipe 100, a plurality of support plates 300 are fixedly connected. Each support plate 300 is vertically arranged, and the plurality of support plates 300 are arranged at intervals along the circumferential direction of the half pipe 100. A conical top cover 310 is placed on the plurality of support plates 300, and the plurality of support plates 300 jointly support the conical top cover 310. With the support of the plurality of support plates 300, a certain gap is maintained between the conical top cover 310 and the half pipe 100, and the slurry can flow through the gap into the two half pipes 100. When pouring the slurry inside the casting mold composed of the two half pipes 100, the slurry can flow in the casting mold from multiple directions under the guiding action of the conical top cover 310, improving the uniformity during the grouting of the casting mold.

[0040] The implementation principle of a pipe jacking casting mold in an embodiment of the present application is as follows: by staggeredly arranging a plurality of support cross beams 110 and a plurality of support longitudinal beams 120 on the circumferential surface of each half pipe 100, the plurality of support cross beams 110 and the plurality of support longitudinal beams 120 can jointly support the half pipe 100, thereby increasing the overall strength of the casting mold and improving the casting quality of the pipe jacking; at the same time, the conical top cover 310 is used to guide the slurry, improving the uniformity during the grouting of the casting mold.

[0041] Embodiment 2

[0042] Refer to Figure 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that at least two groups of stabilizing mechanisms 400 are provided on each half pipe 100. In this embodiment, two groups of stabilizing mechanisms 400 are provided on each half pipe 100, and the two groups of stabilizing mechanisms 400 are arranged at intervals along the circumferential surface of the half pipe 100. Each group of stabilizing mechanisms 400 includes a pushing member 410 and a clamping block 420. The clamping block 420 penetrates through the wall of the half pipe 100, and the clamping block 420 slides along the direction close to or away from the axis of the half pipe 100. The pushing member 410 is arranged on the half pipe 100, and the pushing member 410 is used to push the clamping block 420 to slide.

[0043] The pushing member 410 includes a lead screw 411 rotatably connected to the outer wall of the half pipe 100. The lead screw 411 is perpendicular to the axis of the half pipe 100. A slider 412 is threadedly connected to the lead screw 411. The slider 412 is slidably connected to the outer wall of the half pipe 100, and the slider 412 is fixedly connected to the clamping block 420. Before pouring concrete into the two half pipes 100, by rotating the plurality of lead screws 411, the corresponding clamping blocks 420 can be pushed by the plurality of lead screws 411 to move, so as to clamp the conical top cover 310 and improve the stability of the conical top cover 310 during use.

[0044] Refer to Figure 4 and Figure 5, one of the clamping blocks 420 is fixedly connected with a scraping plate 500. The scraping plate 500 includes a fixed part 510 and a rotating part 520. The fixed part 510 is fixedly connected with the clamping block 420, and the rotating part 520 is rotatably connected to the top end of the fixed part 510. The rotating part 520 can be rotated to fit with the conical top cover 310, so that the whole scraping plate 500 can fit with the conical top cover 310; a fixing block 600 is arranged at the top of the conical top cover 310, and the conical top cover 310 is rotatably connected below the fixing block 600. A power member 610 is installed on the fixing block 600. In this embodiment, the power member 610 is a driving motor 620.

After the slurry is poured into the casting mold, the driving motor 620 is used to drive the conical top cover 310 to rotate, so that the scraping plate 500 can scrape and clean the slurry on the conical top cover 310, improving the convenience of cleaning the slurry on the conical top cover 310.

[0045] The implementation principle of the pipe jacking casting mold in the embodiment of the present application is as follows: by passing a plurality of clamping blocks 420 through each half pipe 100, when pouring slurry into the casting mold, pushing the plurality of clamping blocks 420 to slide, so that the plurality of clamping blocks 420 clamp the conical top cover 310, improving the stability of the conical top cover 310 during use. At the same time, by using the rotating setting of the conical top cover 310, after the grouting is completed, the slurry on the top cover can be removed in time.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this.
