Therefore, large pile group foundations are widely used in bridge projects in soft soil areas, and super-long and large-diameter pile groups are the most common ones. However, in actual projects, the spacing of pile foundations is limited by the structural form, resulting in a narrow construction surface. The site needs to be placed with mechanical equipment such as rotary drilling rigs, rotary drilling rigs, truck cranes, crawler cranes, mud filter boxes, excavators, etc., which makes the construction surface problem of pile foundations more prominent.

[0034] The utility model installs the support assembly through the mounting frame assembly. In the process of lowering and splicing the steel cage section by section, the movable plate 22 of the support assembly 2 can slide along the length direction of the fixed plate 21. When the movable plate 22 extends to the avoidance hole, it can support the steel cage 7. The movable plate 22 and the fixed plate 21 are fixed by the locking member, so that the support assembly can provide a stable support. When it is necessary to lower a spliced ​​section of the steel cage, it is only necessary to slide the movable plate 22 away from the steel cage.

[0035] It should be noted that the steel cage 3 is composed of main bars 31, reinforcing bars 32, stirrups and the like.

[0036] Preferably, please refer to Figure 1As shown, the mounting frame assembly 1 includes a flat plate assembly and a jack assembly that supports the flat plate assembly on a construction plane, the flat plate assembly includes an upper plate 1003, a lower plate 1001 and a connecting member 1002, the upper plate 1003 and the lower plate 1001 are arranged in parallel up and down, and the avoidance holes are opened in the centers of the upper plate 1003 and the lower plate 1001, the connecting member 1002 is arranged between the upper plate 1003 and the lower plate 1001 and connects the upper plate 1003 and the lower plate 1001 into a whole, and the supporting assembly 2 is installed between the upper plate 1003 and the lower plate 1001.

[0037] It can be understood that the lower plate 1001 is supported by the jack 1010, and the upper plate 1003 and the lower plate 1001 are connected by the connector 1002. The whole has the characteristics of high rigidity, pressure resistance, tension resistance, and strong stability. At the same time, a support platform component that can be adjusted horizontally by the jack 1010 is formed, so that the top surface of the platform is always in a horizontal state to meet the requirements of installing various devices on the construction platform device 1. The connector 1002 can be made of I-beams, and the upper plate 1003 and the lower plate 1001 can be made of steel plates made of high-quality steel. The through hole in the center of the upper plate 1003 and the lower plate 1001 is a cut-out avoidance hole to facilitate the lowering of the steel cage 7.

[0038] It should be noted that the mounting frame assembly 1 can not only install the supporting assembly 2, but also be expanded to install a lifting assembly for lifting the steel cage, by setting a fixed sleeve 1005 between the upper plate 1003 and the lower plate 1001, and the fixed sleeve 1005 is used to install the mounting column of the lifting assembly; a guide rail 1006 is provided on the mounting frame assembly 1, and the bottom surface of the guide rail 1006 is welded to the top surface of the upper plate 1003, and two end blocks 1008 are welded at both ends of the guide rail 1006, and a group of guide rail limit holes 1007 are equidistantly cut on the waist steel plate of the guide rail 1006.

[0039] Preferably, please refer to Figure 2 As shown, the jack assembly includes a jack 1010 and a pad 1012.

[0043] Preferably, please refer to Figure 3 As shown, the support assembly 2 also includes a pulley block 26 , the fixed plate 21 is fixedly connected between the upper plate 1003 and the lower plate 1001 , the pulley block 26 is installed on the bottom surface of the movable plate 22 , and the movable plate 22 is movably installed on the lower plate 1001 through the pulley block 26 .

[0044] It can be understood that the fixed plate 21 is fixedly connected between the upper plate 1003 and the lower plate 1001, and the movable plate 22 can slide along the length direction of the fixed plate 21. The movable plate 22 extends to the through hole in the center of the upper plate 1003 and the lower plate 1001, that is, the avoidance hole, to support the steel cage 7, wherein the pulley block 26 can save manpower to push the movable plate 22. The locking member can be a bolt, which cooperates with the preset screw holes on the fixed plate 21 and the movable plate 22 to fasten the two.

[0045] Preferably, please refer to Figure 3 As shown, the fixed plate 21 is provided with a first bolt hole 23 , and the movable plate 22 is provided with a group of limiting through holes. The locking member is used to pass through the limiting through holes and the first bolt holes 23 in sequence to fix the fixed plate 21 and the movable plate 22 .

The stopper 24 is used to press against the fixed plate 21 when the movable plate 22 moves to a first preset position in a direction away from the avoidance hole. The stopper 24 is also used to hook the steel cage 3 when the movable plate 22 extends into the steel cage 3.

[0048] It can be understood that the setting of the stopper 24, firstly, prevents the front end of the movable plate 22 from moving out of the fixed plate 21 to the rear end, thereby playing a limiting role; secondly, the front end of the movable plate 22 extends into the steel cage 7 and is placed at the bottom of the reinforcing rib 72 of the steel cage 7, which can hook, overhang and support the steel cage 7, so that the steel cage 7 does not slide into the cast-in-place pile hole, thereby playing a fixing role.

[0049] Preferably, please refer to Figure 3 As shown, a push rod 25 is provided at one end of the movable plate 22 away from the avoidance hole, and the push rod 25 is used to push the movable plate 22 to move. The push rod 25 is also used to press against the fixed plate 21 when the movable plate 22 moves to a second preset position in a direction close to the avoidance hole.

[0050] In some preferred embodiments, hand push rods 25 made of round steel bars are vertically welded on both side surfaces at the middle position of the height side of the movable plate 22, so as to facilitate the operator to push the movable plate 22 to move toward the front end, and also prevent the rear end of the movable plate 22 from moving toward the front end and out of the fixed plate 21, thereby playing a limiting role.
