Abstract

This utility model discloses a foundation pit guardrail structure for geotechnical engineering, belonging to the field of geotechnical engineering protection technology. It includes a base, with two support columns fixedly connected to both sides of the top of the base. A guardrail frame is fixedly connected between the two support columns. Two snap-fit ​​frames are fixedly installed on the side of one support column away from the guardrail frame, and an mounting seat is fixedly installed at the center of the side of the other support column away from the guardrail frame. This foundation pit guardrail structure for geotechnical engineering, by setting a rotating seat, a plug-in block, a snap-fit ​​frame, and a limiting seat, allows the rotating seat to rotate to a suitable angle.

Technical Field

[0001] This utility model belongs to the field of geotechnical engineering protection technology, specifically a geotechnical engineering foundation pit guardrail structure. Background Technology

[0002] Geotechnical engineering is an important branch of civil engineering, mainly studying the engineering properties of rocks and soils and their applications in engineering construction. A foundation pit is an excavation site located at the foundation design position, according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data, combined with the conditions of nearby buildings, and waterproofing and drainage work should be carried out. At the construction site, guardrails effectively isolate workers from hazardous sources, directly reducing the accident rate; they are an extremely effective safety protection measure. However, existing guardrail structures are difficult to adjust the installation angle, reducing their practicality, and require fastening and connection using bolts or binding, resulting in low assembly and disassembly efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a geotechnical engineering foundation pit guardrail structure, which solves the problems of difficulty in adjusting the installation angle of the guardrail structure during use, which reduces the practicality of the guardrail structure, and the need for fastening and connection by bolts or binding, resulting in low assembly and disassembly efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a geotechnical engineering foundation pit guardrail structure, comprising a base, two support columns fixedly connected to the top two sides of the base, a guardrail frame fixedly connected between the two support columns, two snap-fit ​​frames fixedly installed on the side of one support column away from the guardrail frame, and an installation seat fixedly installed at the center of the side of the other support column away from the guardrail frame. The same rotating seat is rotatably connected to both sides of the installation seat via pins. Two plug-in blocks are fixedly connected to one side of the rotating seat, and the plug-in blocks correspond to the snap-fit ​​frames. A sliding rod is fixedly connected to the middle of the bottom of the rotating seat. Twelve plug-in slots are formed at the bottom of the rotating seat outside the sliding rod. A sliding groove is formed on one side of the support column at the bottom of the rotating seat. A movable block is slidably connected through the sliding groove. A limiting seat is fixedly connected to one side of the movable block extending from the sliding groove. The limiting seat is slidably connected through the sliding rod. Twelve plug-in columns are fixedly connected to the top of the limiting seat, and the plug-in columns correspond to the plug-in slots.

[0005] As a further embodiment of this utility model: the support column is fixedly connected to the top of the slide groove with an installation frame, and two screws are threaded through the two sides of the installation frame, with a limit block installed at one end of the screw inside the installation frame.

[0006] As a further embodiment of this utility model: the limiting seat is provided with limiting grooves on both sides, and the limiting block is positioned corresponding to the limiting groove.

[0007] As a further embodiment of this utility model: an electric telescopic rod is rotatably connected to the top of the inner support column via a pin, and a fixed seat is installed at the telescopic end of the bottom of the electric telescopic rod.

[0008] As a further embodiment of this utility model: the fixed base is rotatably connected to a support base via a pin, and four pins are fixedly connected to the bottom of the support base.

[0009] As a further embodiment of this utility model: a fixing block is fixedly installed at the center position on both sides of the opening on the surface of the support column, and a snap-fit ​​block is fixedly installed on one side of the fixing block.

[0010] As a further embodiment of this utility model: a rotating rod is rotatably installed on the surface of the support column at a position opposite to the fixing block via a pin, and the rotating rod is engaged with the locking block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This geotechnical engineering foundation pit guardrail structure, by setting a rotating seat, plug-in block, snap-fit ​​frame and limiting seat, rotates the rotating seat. After the rotating seat rotates to a suitable angle, the limiting seat moves upward. The limiting seat drives the plug-in column to insert into the plug-in groove at the bottom of the rotating seat, thereby limiting the rotating seat. The snap-fit ​​frame is aligned with the plug-in block, and the snap-fit ​​frame is moved downward so that the snap-fit ​​frame and the plug-in block are plugged in, thereby realizing the installation of two support columns. In addition, it can realize the assembly of two guardrail structures at different angles, improving the practicality of the guardrail structure.

[0013] 2. The foundation pit guardrail structure for this geotechnical engineering project utilizes a locking block, a rotating rod, an electric telescopic rod, and a support base. Pressing the locking block removes its restriction on the rotating rod. Rotating the rotating rod causes it to detach from the top of the locking block, thus removing its restriction on the electric telescopic rod. The electric telescopic rod then rotates out of the support column. Activating the electric telescopic rod causes it to move through the fixed base, which in turn moves the support base, causing the support base to insert the pins into the ground. This allows the pins to work with the electric telescopic rod to support the support column, improving the stability of the guardrail structure during use. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a geotechnical engineering foundation pit guardrail structure, including a base 1, two support columns 2 fixedly connected to the top two sides of the base 1, an installation frame 14 fixedly connected to the top of the support columns 2 at the top of the sliding groove 9, two screw rods 15 threadedly connected to both sides of the installation frame 14, a limit block 16 installed at one end of the screw rod 15 inside the installation frame 14, a limit groove 13 is provided on both sides of the limit seat 11, the limit block 16 is positioned corresponding to the limit groove 13, by setting the screw rod 15, rotating the screw rod 15, the screw rod 15 can drive the limit block 16 to move, so that the limit block 16 is inserted into the limit groove 13, thereby realizing the limit of the limit seat 11;

[0021] An electric telescopic rod 18 is rotatably connected to the top of the support column 2 via a pin. A fixed seat 19 is installed at the telescopic end of the electric telescopic rod 18. By setting the electric telescopic rod 18, the electric telescopic rod 18 pushes the fixed seat 19 to move, so that the fixed seat 19 can drive the support seat 20 to contact the ground, thereby allowing the electric telescopic rod 18 to cooperate with the support seat 20 to achieve stable support for the support column 2.

[0022] The fixed base 19 is rotatably connected to the support base 20 through a pin. Four pins 21 are fixedly connected to the bottom of the support base 20. By setting the pins 21, the pins 21 are inserted into the ground as the support base 20 moves, which improves the stability of the support base 20 when it contacts the ground to support the support column 2.

[0023] Fixing blocks 22 are fixedly installed at the center of both sides of the opening on the surface of the support column 2. A snap-fit ​​block 23 is fixedly installed on one side of the fixing block 22. A rotating rod 24 is rotatably installed on the surface of the support column 2 opposite to the fixing block 22 via a pin shaft. The rotating rod 24 and the snap-fit ​​block 23 are snapped together. By setting the snap-fit ​​block 23, the snap-fit ​​block 23 is snapped with the rotating rod 24, thereby fixing the rotating rod 24 to the top of the fixing block 22. This allows the rotating rod 24 to limit the electric telescopic rod 18 and ensure that the electric telescopic rod 18 will not shake randomly when stored inside the support column 2.

[0024] A guardrail frame 17 is fixedly connected between two support columns 2. Two snap-fit ​​frames 3 are fixedly installed on the side of one support column 2 away from the guardrail frame 17. An installation seat 4 is fixedly installed at the center of the side of the other support column 2 away from the guardrail frame 17. The same rotating seat 5 is rotatably connected to both sides of the installation seat 4 through pins. Two plug-in blocks 6 are fixedly connected to one side of the rotating seat 5, and the plug-in blocks 6 correspond to the snap-fit ​​frames 3. A slide rod 7 is fixedly connected to the middle of the bottom of the rotating seat 5. Twelve plug-in slots 8 are opened at the bottom of the rotating seat 5 outside the slide rod 7. By setting the slide rod 7, the limiting seat 11 slides outside the slide rod 7, so that the slide rod 7 can limit the limiting seat 11, so that the limiting seat 11 stably drives the plug-in column 12 to plug into the plug-in slots 8.

[0025] The support column 2 has a groove 9 on one side of the bottom of the rotating seat 5. A movable block 10 is slidably connected through the groove 9. A limit seat 11 is fixedly connected to the groove 9 on one side of the movable block 10. The limit seat 11 is slidably connected to the slide rod 7. Twelve plug-in columns 12 are fixedly connected to the top of the limit seat 11. The plug-in columns 12 are positioned corresponding to the plug-in slots 8. By setting the plug-in columns 12, the plug-in columns 12 are inserted into the plug-in slots 8 to limit the rotation seat 5 and adjust the angle when the two sets of guardrails are spliced.

[0026] The working principle of this utility model is as follows:

[0027] Place base 1 on the ground, rotate rotating seat 5, rotating seat 5 drives plug-in block 6 to rotate to a suitable position, move limiting seat 11 upward, limiting seat 11 drives plug-in post 12 to move, so that plug-in post 12 is plugged into plug-in slot 8, realizing the limitation of rotating seat 5. Rotate screw 15, screw 15 drives limiting block 16 to move, so that limiting block 16 is inserted into limiting slot 13, thus realizing the limitation of limiting seat 11. Then align the snap-fit ​​frame 3 of another guardrail structure with the adjusted plug-in block 6, move snap-fit ​​frame 3 downward, snap-fit ​​frame 3 is plugged into plug-in block 6, from To achieve the fixed installation of the two guardrail structures, press the locking block 23 to remove the limiting effect of the locking block 23 on the rotating rod 24, rotate the rotating rod 24, and the rotating rod 24 rotates away from the top of the fixing block 22, thereby removing the limiting effect on the electric telescopic rod 18, rotating the electric telescopic rod 18 out of the support column 2, and starting the electric telescopic rod 18. The electric telescopic rod 18 drives the support seat 20 to move through the fixing seat 19, so that the support seat 20 drives the pin 21 to be inserted into the ground, thereby fixing the support seat 20, so that the support seat 20 cooperates with the electric telescopic rod 18 to support and fix the support column 2.
