Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic foundation pit protection equipment, and in particular to a hydraulic foundation pit protection structure. Background Technology

[0002] With the rapid development of water conservancy construction in my country, foundation pit support technology, as a key link in the construction of water conservancy infrastructure, directly affects the quality and progress of the project in terms of its safety and construction efficiency.

[0003] Traditional foundation pits often present the following problems: Insufficient soil stability: Traditional protective structures mostly use rigid fixing systems, which frequently disturb the surrounding soil during construction, leading to loosening of the soil on the pit sidewalls and stress imbalance, which can easily cause local collapse or settlement. This phenomenon not only increases the cost of later support, but also forces the construction process to be interrupted repeatedly for reinforcement, which seriously restricts construction efficiency and has poor construction convenience. Traditional protective structures mostly use on-site welding or bolt fixing methods, with low standardization of components, time-consuming and labor-intensive transportation and installation, and the need for professional welding equipment, which is difficult to meet the needs of rapid construction in modern engineering. Therefore, the above problems need to be improved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic foundation pit protection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic foundation pit protection structure, comprising two bases, wherein the upper end of the bases has multiple equidistant through holes, and one side of the bases has a sliding groove; reinforcing bars are respectively installed in the multiple through holes of the bases, and a protective block is slidably installed in the sliding groove of the bases, and a protective block is provided on the upper end of the same side of the protective block.

[0006] Preferably, the protective block has two identical threaded through holes on the outer side of one end, and the protective block is installed on the base by bolts; the protective block has an anchor through hole on the inner side of the other end, and a mounting platform is fixed to the lower end of the protective block on the same side.

[0007] Preferably, a fixing platform is installed on the outer side of the lower end of the lower protective block, and the fixing platform is slidably installed in a sliding groove on one side of the base.

[0008] Preferably, the inner side of the protective block is fitted with steel pipes, and the other ends of the four steel pipes are connected to the same main screw.

[0009] Preferably, a protective net is provided between the protective block and the fixed platform, and the protective net is connected by a screw installed in the threaded through hole.

[0010] Preferably, a main reinforcing bar is installed on the inner side of the other end of the protective block, and the main reinforcing bar is installed through the anchor nail through hole.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of multiple bases, protective blocks, reinforcing bars, and main reinforcing bars, can initially reinforce the bottom of the foundation pit, increasing the efficiency of foundation pit protection. It solves the problem of traditional foundation pit protection structures slowing down construction progress due to soil loosening during construction, thus improving construction efficiency. Through the cooperation between steel pipes and protective netting, it prevents mud and stones from rolling down the steep slope of the foundation pit due to vibration, thus preventing injuries to personnel. It solves the problem of traditional foundation pits causing delays due to mud or stones falling on construction workers, thus improving personnel safety. Through the cooperation between steel pipes and main screws, it is easy to connect to various protective blocks and bases, achieving multi-modal design. This allows the product to be used for foundation pits of different sizes and can be combined for installation, solving the problem of traditional foundation pit products being unable to be portable and installed, thus improving product convenience.
