Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a foundation pit support structure for a rainwater collection tank. Background Technology

[0002] Rainwater harvesting tanks can collect rainwater runoff from rooftops, roads, plazas, and other areas, storing the rainwater for later use. In some water-scarce areas, the collected rainwater can be used for irrigation, car washing, toilet flushing, etc., realizing the reuse of water resources. During the construction of rainwater harvesting tanks, support plates are needed to support the foundation pit of the collection tank.

[0003] The aforementioned device lacks an adjustable support structure for the support plates, which means that existing foundation pit support plates require additional support arms between the opposing support plates to improve stability and enhance the support effect. However, since different foundation pits have different lengths and widths, most existing support arms are of fixed length or customized according to the size of the foundation pit, making them cumbersome and limiting. Based on the shortcomings of existing technology, this utility model designs a foundation pit support structure for a rainwater collection tank. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a foundation pit support structure for a rainwater collection tank, which has the advantage of adjustable support plates.

[0012] As a preferred embodiment of this utility model, the first connecting bolt is inserted into the interior of the second socket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of rainwater collection tank foundation pit support structure involves fixing multiple main support plates or first insertion holes, each with side frames installed on its inner side, to the inner wall of the foundation pit as required by insertion or fitting. Then, two support arms connected to the adjustment mechanism are placed between the two main support plates or first insertion holes. At this point, two sets of connecting seats are placed in the slides opened on the side frames on both sides, and positioning pins are inserted into the side holes and connecting seats for locking. If one end of the connecting seat cannot be connected to the side frame after connection at the other end, simply rotate the handle and threaded rod clockwise or counterclockwise to move it up or down within the connecting arm, thereby driving the lifting push arm accordingly. As the lifting arm moves upward or downward, the lifting push arm pulls the adjusting support arm to move accordingly, adjusting the length of the two support arms until the connecting seats at both ends are connected to the side frames on both sides. Finally, continuously turn the handle and threaded rod clockwise to move it downward within the connecting arm. The downward-moving threaded rod pushes the lifting push arm downward, pushing the adjusting support arms connected at both ends outward to increase the length of the combined support arm and adjusting mechanism. This increases the support force of the support arm and adjusting mechanism on the left and right main support plates or the first insertion hole. This device facilitates the support of the foundation pit. Attached Figure Description

[0025] Please see Figure 4-5 A side hole 201 is provided on one side of the side frame 2, and a slide rail 202 is provided on one side of the side hole 201. A connecting seat 203 is provided inside the slide rail 202. A positioning pin 204 is inserted into the side hole 201. A first connecting head 205 is rotatably connected inside the connecting seat 203. A connecting shaft 206 is inserted between the connecting seat 203 and the first connecting head 205. A support arm 207 is fixedly connected to one end of the first connecting head 205. A second connecting head 208 is fixedly connected to the other end of the support arm 207.

The side frame 2 is fixedly connected to the inside of the first insertion hole 101.

[0026] By providing side holes 201, slides 202, connecting seats 203 and positioning pins 204, support can be provided for the main support plate 1 or the first insertion hole 101 at different positions as needed. By providing the first connector 205 and connecting shaft 206, support can still be provided when the support points of the left and right main support plates 1 are at different heights.

[0027] Working principle: When a foundation pit support structure for a rainwater collection tank is used, in the initial state, firstly, the main support plate 1 has first insertion holes 101 and first connecting bolts 102 on both sides respectively. Second insertion holes 104 and second connecting bolts 105 are also opened on both sides of the secondary support plate 103 for expansion. The first connecting bolts 102 and the second insertion holes 104 are connected by fixing nuts 106 so as to expand and splice the main support plate 1 and the first insertion holes 101 according to the required length of the foundation pit. On the side frame 2 set on the inner side of the two sets of opposing main support plates 1, a connecting seat 203, a first connecting head 205 and a support arm 207 are installed and connected by positioning pins 204 and connecting shafts 206 so as to provide intermediate support for the two sets of main support plates 1. The adjustment mechanism 3 set between the two support arms 207 can adjust the length of the combined two support arms 207 according to the width of the foundation pit to provide support for the main support plate 1 or the first insertion holes 101.

[0028] When support is needed for the foundation pit, firstly, the main support plates 1 or the first insertion holes 101 with side frames 2 installed on their inner sides are inserted or attached to the inner wall of the foundation pit as required. Then, the two support arms 207 connected to the adjustment mechanism 3 are placed between the two main support plates 1 or the first insertion holes 101. At this time, the two sets of connecting seats 203 are placed in the slides 202 opened on the two side frames 2 respectively, and the positioning pins 204 are inserted into the side holes 201 and the connecting seats 203 for locking. If the other end cannot be connected after one end of the connecting seat 203 is connected to the side frame 2, simply rotate the handle 306 and the threaded rod 305 clockwise or counterclockwise to move it up or down in the connecting arm 301, thereby driving the lifting push arm 304 accordingly. When the lifting arm 304 moves up or down, it pulls the adjusting arm 303 to move accordingly and adjusts the length of the two supporting arms 207 until the connecting seats 203 at both ends are connected to the side frames 2 on both sides. Finally, the handle 306 and the threaded rod 305 are continuously turned clockwise to move them down within the connecting arm 301. The moving threaded rod 305 pushes the lifting arm 304 down, pushing the adjusting arm 303 connected at both ends outward to increase the length of the combined supporting arm 207 and adjusting mechanism 3. This increases the support force of the supporting arm 207 and adjusting mechanism 3 on the left and right main support plates 1 or the first insertion hole 101. This device facilitates the support of the foundation pit.
