Embodiment Construction
[0037] The following is attached Figure 1-6 The application is described in further detail.
[0038] The embodiment of the present application discloses a support structure for building foundation pits. refer to figure 1 , figure 2 , including several rectangular soil retaining boards 1 installed on the opposite inner walls of the foundation pit 6 . All the retaining boards 1 face each other in pairs, and a support rod 2 for providing support for the retaining boards 1 is arranged between the two facing retaining boards 1 .
[0039] refer to figure 1 , image 3 The support rod 2 includes an adjusting screw 21 and two fixing rods 22 for tightening the retaining plate 1. The two fixing rods 22 are respectively located at both ends of the adjusting screw 21, and the adjusting screw 21 is a two-way screw. One end of the two fixing rods 22 facing the adjusting screw 21 is provided with an adjusting groove 221 along its length direction for the adjusting screw 21 to snap int...

The invention relates to a house building foundation pit supporting structure which comprises a plurality of soil retaining plates installed on the two opposite inner side walls of a foundation pit. A supporting rod is arranged between every two opposite supporting plates; each supporting rod comprises an adjusting screw rod and two fixing rods used for abutting against the corresponding soil retaining plate; adjusting grooves allowing one end of each adjusting screw rod to be clamped in are formed in the end, away from the soil retaining plates, of the fixing rods; the adjusting screw rods are in threaded connection with the inner side walls of the adjusting grooves; a fixing piece used for limiting rotation of the adjusting screw rods is arranged on each fixing rod; and each fixing rod is detachably connected with the corresponding soil retaining plate through a limiting piece. The soil retaining plates are firstly installed on the inner side walls of the two sides of the foundation pit one by one, then the adjusting screw rods are rotated according to the width of the foundation pit, the length of the supporting rods is adjusted by adjusting the length of the parts, stretching into the adjusting grooves, of the adjusting screw rods, and the two ends of the supporting rods abut against the soil retaining plates, so that the supporting rods can be matched with the foundation pits with different widths.
Description
technical field [0001] The application relates to the field of foundation pit support, in particular to a building foundation pit support structure and a construction method thereof. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. [0003] At present, the common method of foundation pit support is to place the soil retaining boards one by one on the two opposite inner walls of the foundation pit, and a brace is arranged between each pair of facing soil retaining boards. The boards are clamped by wooden wedges, and the braces can give the retaining board a supporting force, so that the retaining board can provide support for the inner wall of the foundation pit and prevent the inner wall of the foundation pit f...
