[0042] like Figure 2 As shown, this embodiment provides a roller-type pressure roller 1, which includes two mounting plates 11, multiple connecting shafts 12 and multiple rollers 13.

[0043] Two mounting plates 11 are used to fix the bottom plate 21, the first side plate 22, and the second side plate 23 of the foundation trench 3. The bottom plate 21, the first side plate 22, and the second side plate 23 are used to form a U-shaped ground beam casting trench. One mounting plate 11 is used to fix the bottom plate 21 and the first side plate 22, and the other mounting plate 11 is used to fix the bottom plate 21 and the second side plate 23. The mounting plates 11 are preferably channel steel. The mounting plates 11 may include a vertically arranged first connecting plate and two horizontally arranged second connecting plates. The two ends of the vertically arranged first connecting plate are respectively connected to the two horizontally arranged second connecting plates to form a C-shaped structure. The openings of the two mounting plates 11 are arranged facing away from each other. The mounting plates 11 and the bottom plate 21 are detachably connected by fasteners 14. The bottom plate 21 is detachably connected to the first side plate 22 and the second side plate 23 by connecting components 24, which improves the portability of disassembly. The fasteners 14 are preferably C-shaped buckles. The connecting components 24 are preferably steel pipes.

[0044] One end of the connecting shaft 12 is connected to a mounting plate 11, and the other end of the connecting shaft 12 is connected to another mounting plate 11. The plurality of connecting shafts 12 are arranged along the length of the base groove 3 and evenly connect the two mounting plates 11.

[0045] The plurality of rollers 13 are sequentially rotatably mounted between the two mounting plates 11 and located below the connecting shaft 12, for rolling and compacting the bottom of the base groove 3.

[0046] Specifically, the first connecting plates of the two mounting plates 11 are first connected together by multiple connecting shafts 12. Then, multiple rollers 13 are rotatably mounted on the first connecting plates of the two mounting plates 11 and located below the connecting shafts 12. After the roller pressure rollers 1 are installed, the two ends of the base plate 21 along the length direction of the base groove 3 are mounted on the two mounting plates 11 by fasteners 14. Then, the first side plate 22 and the second side plate 23 are respectively installed on the two ends of the base plate 21 along the width direction of the base groove 3. The first side plate 22 and the base plate 21 are detachably connected by a connecting assembly 24, and the second side plate 23 and the base plate 21 are detachably connected by a connecting assembly 24. The connecting assembly 24 can be an oblique connecting rod or a connecting plate. The assembled base plate 21, first side plate 22, second side plate 23 and pressure roller are hoisted into the foundation trench 3. The roller pressure roller 1 drives the base plate 21, first side plate 22 and second side plate 23 to move along a preset path to a designated position, for example, from one end of the foundation trench 3 to the other end along the length of the foundation trench 3. During the movement, multiple rollers 13 compact and flatten the path. After the movement is in place, the base plate 21 and roller pressure roller 1 are moved out of the foundation trench 3. Then the base plate 21 is hoisted separately to the bottom of the foundation trench 3 to form a U-shaped ground beam casting trench with the first side plate 22 and the second side plate 23.

[0047] The bottom plate 21, the first side plate 22 and the second side plate 23 are driven by the roller-type compression wheel 1 to compact and flatten the bottom of the foundation trench 3, thereby improving the construction quality of the foundation beam in the foundation trench 3 and the safety during the construction process, ensuring the construction efficiency, and solving the problems of poor quality of the foundation beam and inclination of the wall body caused by the soft and uneven bottom of the foundation trench 3 in the prior art.

[0048] As shown in Figure 1 The embodiment also provides a walking type self-compaction tire mold.

[0049] The prefabricated tire mold 2 includes a bottom plate 21, a first side plate 22 and a second side plate 23. The bottom plate 21, the first side plate 22 and the second side plate 23 are formed by pre-concreting. The bottom plate 21 is used to be installed at the bottom of the foundation trench 3, the first side plate 22 and the second side plate 23 are used to be installed at the two inner walls of the foundation trench 3 and located at the two ends of the bottom plate 21, and the bottom plate 21, the first side plate 22 and the second side plate 23 are used to form a U-shaped pouring mold.

[0050] Specifically, the bottom plate 21 is first detachably installed on the two mounting plates 11 of the roller-type compression wheel 1 at the two ends along the length direction of the foundation trench 3 through the fasteners 14, and then the bottom plate 21 is detachably connected with the first side plate 22 and the second side plate 23 at the two ends along the width direction of the foundation trench 3 through the connecting assembly 24, so as to fix the first side plate 22 and the second side plate 23. The prefabricated tire mold 2 and the roller-type compression wheel 1 are moved into the foundation trench 3, and the bottom plate 21, the first side plate 22 and the second side plate 23 are driven by the roller-type compression wheel 1 to move along the preset path of the foundation trench 3. During the movement, the plurality of rollers 13 of the roller-type compression wheel 1 compact and flatten the section path. After moving to the specified position, the bottom plate 21 and the roller-type compression wheel 1 are moved out of the foundation trench 3, and then the bottom plate 21 is hoisted alone to the bottom of the foundation trench 3 to form a U-shaped pouring mold with the first side plate 22 and the second side plate 23.

[0051] In the above structure, by arranging the prefabricated tire mold 2, the time for traditional construction of brick laying is saved, the construction risk is reduced, and the construction efficiency and construction quality are provided. By arranging the roller-type compression wheel 1 to drive the prefabricated tire mold 2 to move to the specified position of the foundation trench 3, the compaction and flattening of the bottom of the foundation pit are realized, and the rapid installation of the prefabricated tire mold 2 is also realized.

[0052] As shown in Figure 1As shown, as a preferred embodiment, the bottom plate 21 is provided with a plurality of lifting lugs 25 for lifting the bottom plate 21. The lifting lugs 25 are detachably mounted on the bottom plate 21. After the roller-type compression wheel 1 drives the bottom plate 21, the first side plate 22 and the second side plate 23 to move to the designated position, the lifting lugs 25 are connected by the external lifting equipment to move the bottom plate 21 and the roller-type compression wheel 1 out of the foundation trench 3, and then the bottom plate 21 is separated from the roller-type compression wheel 1. After that, the lifting lugs 25 are connected by the external lifting equipment to move the bottom plate 21 into the bottom of the foundation trench 3 and between the first side plate 22 and the second side plate 23. After the bottom plate 21 is installed in place, the lifting lugs 25 are removed, so that the bottom plate 21, the first side plate 22 and the second side plate 23 form a U-shaped pouring formwork. The arrangement of the lifting lugs 25 not only improves the lifting portability, but also improves the installation efficiency of the prefabricated mold 2.

[0053] The embodiment also provides a walking type self-compaction mold construction method, which comprises the following steps: S1-S6, and can further comprise: S7-S8.

[0054] S1: excavate the foundation trench 3, and the cross-sectional shape of the foundation trench 3 along the direction perpendicular to the length can be an inverted isosceles trapezoid.

[0055] S2: place the walking type self-compaction mold at an initial position in the foundation trench 3.

[0056] S3: move the roller-type compression wheel 1 of the walking type self-compaction mold along a preset path, and the roller-type compression wheel 1 drives the bottom plate 21, the first side plate 22 and the second side plate 23 to move. During the movement, the plurality of rollers 13 of the roller-type compression wheel 1 compact and flatten the bottom of the foundation trench 3. A plurality of walking type self-compaction molds are placed at initial positions in the foundation trench 3 in turn, and are moved to designated positions along a preset path, so that continuous multiple compactions of the foundation trench 3 path are realized, and the construction quality of the foundation bottom is guaranteed.

[0057] S4: after the walking type self-compaction mold moves to the designated position along the preset path, the bottom plate 21 and the roller-type compression wheel 1 are moved out of the foundation trench 3 by the lifting equipment, and the fasteners 14 are disengaged, so that the bottom plate 21 and the roller-type compression wheel 1 are separated. The roller-type compression wheel 1 can be used in rotation, and the utilization rate is improved.

[0058] S5: transfer the separated bottom plate 21 to the bottom of the foundation trench 3 and between the first side plate 22 and the second side plate 23 to form a U-shaped foundation trench pouring groove.

[0059] S6: repeat steps S2-S5 to complete the installation of all prefabricated molds 2 of the foundation trench 3.

[0060] S7: When all the prefabricated formwork 2 in the foundation trench 3 is installed, the foundation beam pouring trench is formed, and the waterproof coiled material 4 is laid on the bottom and inner wall of the foundation beam pouring trench. The use of waterproof coiled material 4 instead of brick membrane requires the use of mortar material, simplifies the process, saves material cost, and improves the overall waterproof effect.

[0061] S8: Pouring concrete in the foundation beam pouring trench to complete the foundation beam construction.

[0062] The above method drives the prefabricated formwork 2 to move to the designated position of the foundation trench 3 by the roller-type compression wheel 1, which not only realizes the compaction and flattening of the bottom of the foundation pit, but also realizes the rapid installation of the prefabricated formwork 2. This method not only improves the quality of the foundation beam construction, but also reduces the construction risk, ensuring the safety and construction efficiency of the foundation trench 3.
