Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a deep foundation pit slope protection device. Background Technology

[0002] With the rapid development of the construction industry, basement structural engineering (including civil defense engineering) is widely used in building construction. Depending on the geological conditions, construction units will choose appropriate foundation pit support construction methods. For foundation pits with shallow excavation depths, above the groundwater level, or with artificial backfill, cohesive soil, or weakly cemented sand after artificial dewatering, improving construction progress and reducing material waste become key factors to consider during construction.

[0003] Traditional deep foundation pit reinforcement uses a combination of steel bars and concrete columns for support, which consumes a large amount of steel bars, concrete and other materials. At the same time, the construction materials cannot be recycled and reused, and the construction cycle is long, which not only slows down the construction progress but also wastes materials. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a deep foundation pit slope protection device, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep foundation pit slope protection device, installed on a slope, comprising several anchors and protective plates. The anchors include a base plate, anchor rods, and a cross-shaped connecting frame. The anchor rods are located at the bottom of the base plate and are used to penetrate into the slope. The connecting frame is located at the top of the base plate, with four protective plates connected to the four corners of each connecting frame. Each protective plate has an L-shaped connecting plate at its corner that matches the corner of the connecting frame. The connecting frame and the connecting plates have corresponding fixing holes and are connected by fixing bolts.

[0006] Preferably, it also includes a reinforcement component, which includes a base and a plurality of reinforcing rods. The plurality of reinforcing rods are disposed on the base, and a nut seat is provided on the protective plate. The ends of the reinforcing rods are threadedly connected to a reinforcing bolt corresponding to the nut seat.

[0007] Preferably, the reinforcing rod is hinged to the base, and several reinforcing rods are arranged circumferentially at equal angles on the base.

[0008] Preferably, each base is provided with four reinforcing rods, and each protective plate is provided with four nut seats. The four reinforcing rods on each base are respectively connected to the nut seats on the four adjacent protective plates.

[0009] Preferably, the reinforcing rod is a telescopic rod.

[0010] This utility model provides a deep foundation pit slope protection device. It has the following beneficial effects:

[0011] 1. This deep foundation pit slope protection device adopts modular anchors, protective plates and reinforcement components. During installation, the appropriate number of modules can be assembled according to the depth and length of the slope. At the same time, the anchors, protective plates and reinforcement components are connected by simple bolts, which makes installation and disassembly convenient. After disassembly, they can be reused, which can greatly reduce the support cost of the slope. Attached Figure Description

[0017] This utility model embodiment provides a deep foundation pit slope protection device, such as... Figure 1-4 As shown, it includes several anchors 2 and protective plates 3. The protective plates 3 are arranged in a rectangular shape, and an anchor 2 is set between four adjacent protective plates 3.

[0018] like Figure 3 As shown, the anchor 2 includes a base plate 21, anchor rods 22, and a cross-shaped connecting frame 23. Anchor rods 22 are located at the bottom of the base plate 21 and are used to penetrate into the slope 1. During installation, the anchor rods 22 are completely driven into the slope 1, leaving the top of the base plate 21 exposed. The connecting frame 23 is located at the top of the base plate 21. Four protective plates 3 are connected to the four corners of each connecting frame 23. Each protective plate 3 has an L-shaped connecting plate 4 at one corner that matches the corner of the connecting frame 23. Corresponding fixing holes 24 are provided on the connecting frame 23 and the connecting plates 4, and a fixing bolt 5 passes through them for connection. During installation, one corner of each of the four protective plates 3 is placed inside the four corners of the connecting frame 23. The fixing bolt 5 passes through the fixing holes on the connecting plates 4 of two adjacent protective plates 3 and is then locked with a nut. The locking between pairs of protective plates 3 helps increase the overall strength of the protective device.

[0019] like Figure 1As shown, in order to enhance the overall strength, the device also includes a reinforcement component, which includes a base 6 and several reinforcing rods 7. Several reinforcing rods 7 are arranged on the base 6, and a nut seat 8 is provided on the protective plate 3. The ends of the reinforcing rods 7 are threadedly connected to reinforcing bolts 9 corresponding to the nut seat 8.

[0020] As a preferred embodiment, each base 6 is provided with four reinforcing rods 7, which are arranged circumferentially at equal angles on the base 6. Each protective plate 3 is provided with four nut seats 8, and the four reinforcing rods 7 on each base 6 are respectively connected to the nut seats 8 on the four adjacent protective plates 3. During installation, the base 6 is placed above the base plate 21, and the four reinforcing rods 7 are respectively connected to the nut seats 8 on the four protective plates 3 to form a mesh-like tensioning structure, thereby enhancing the overall strength of the protective device.

[0021] For easy storage, the reinforcing rods 7 are hinged to the base 6. When the protective device is removed, the four reinforcing rods 7 can be bent upwards at 90° for easy storage and transportation.

[0022] The reinforcing rod 7 is a telescopic rod. The telescopic rod can be a sleeve with a large and a small diameter. At the same time, a spring for resetting can be installed at the bottom of the small sleeve inside the large sleeve. The two ends of the spring are connected to the large sleeve and the small sleeve.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
