[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the present application discloses a protective device for deep foundation pit construction of building construction.

[0025] Reference Figure 1 、 Figure 2 as well as Figure 3 The protective device for deep foundation pit construction includes a base 1, on which are mounted a plurality of parallel fences 2. The fences 2 are arranged vertically and spaced apart along the length of the base 1. The device also includes a mounting base 3 secured to the ground around the foundation pit by concrete pouring. The bottom of the base 1 is provided with a mounting slot 10 for insertion into the exterior of the mounting base 3.

[0026] like Figure 3 、 Figure 4 As shown, a screw rod 4 is rotatably mounted on the base 1 and extends through a mounting slot 10. The length of the screw rod 4 extends along the width of the base 1. Both ends of the screw rod 4 are fixed to the base 1. A clamping frame 5 is threadedly connected to the screw rod 4 and slides within the mounting slot 10. Two guide rods 6 are fixedly mounted on the inner sidewall of the mounting slot 10, symmetrically arranged on either side of the screw rod 4. The length of the guide rods 6 coincides with that of the screw rod 4. The two sides of the clamping frame 5 are movably mounted outside the opposing guide rods 6. The screw rod 4 is used to drive the clamping frame 5 to move along the two guide rods 6 toward or away from the mounting base 3.

[0027] like Figure 2 、 Figure 5as well as Figure 6 As shown, the clamping frame 5 is fixedly mounted with an insertion rod 50 facing the mounting seat 3. The mounting seat 3 is provided with a slot 30 facing the insertion rod 50 on the outer side wall in the vertical direction. The insertion rod 50 is inserted into the slot 30 along the sliding direction of the clamping frame 5. The clamping frame 5 is also fixedly bonded with a rubber anti-skid pad 51 facing the outer side wall of the mounting seat 3. When the insertion rod 50 is inserted into the slot 30, the rubber anti-skid pad 51 and the outer side wall of the mounting seat 3 are in contact with each other.

[0028] like Figure 5 、 Figure 6 As shown, one end of the screw rod 4 is coaxially fixed to a turntable 40 located outside the base 1. A fastener 41 is eccentrically inserted through the turntable 40. In this embodiment, the fastener 41 is a butterfly bolt. The outer wall of the base 1 is provided with multiple threaded holes 11 for screwing the ends of the fasteners 41 into the base 1. The threaded holes 11 are evenly spaced around the screw rod 4. Each threaded hole 11 is located along the rotation path of the fastener 41 as it rotates with the turntable 40.

[0029] like Figure 5 、 Figure 6 As shown, a gear 42 is coaxially fixed on one end of the screw rod 4 away from the turntable 40, and a gear condition 12 is provided on the base 1 so as to slide in the vertical direction and is located on one side of the gear 42, with one side of the gear 42 meshing with the gear condition 12. The gear 42 is used to drive the gear condition 12 to rise and fall in the vertical direction, and a fixing rod 7 for being driven into the ground is provided at the bottom of the gear condition 12. A socket 120 is provided at the bottom of the gear condition 12, and the top of the fixing rod 7 is inserted into and screwed into the socket 120 through a thread. The use of a threaded fixing rod 7 facilitates installation and disassembly, and construction workers can replace the fixing rod 7 with different lengths according to the actual conditions of the ground, thereby ensuring that the fixing rod 7 can be more stably and securely inserted into the ground.

[0030] like Figure 4 As shown, a cleaning seat 8 is movably mounted on the outside of each enclosure rod 2, and the cleaning seat 8 slides along the length direction of the enclosure rod 2 on which it is located. Cleaning cotton 80 is fixedly bonded to the inner side wall of the cleaning seat 8, and the cleaning cotton 80 contacts the outer side wall of the enclosure rod 2 on which it is located. Each cleaning seat 8 is connected and fixed in sequence. When it is necessary to clean the surface of the enclosure rod 2, the surface of the enclosure rod 2 is first wetted, and then each cleaning seat 8 is moved back and forth along the length direction of the enclosure rod 2. The cleaning cotton 80 can wipe the surface of the enclosure rod 2, ensuring the cleanliness of the surface of the enclosure rod 2 and facilitating cleaning.

[0031] The implementation principle is as follows: before installation, the mounting base 3 is cast and fixed on the ground around the foundation pit. The mounting base 3 not only ensures the stability of the base 1 during installation, but also effectively prevents rainwater near the side of the foundation pit from spreading outward, providing waterproof protection for the environment outside the foundation pit. During installation, the base 1 is plugged into the mounting base 3 through the bottom mounting groove 10, and then the screw 4 is rotated to make the clamping frame 5 gradually approach the mounting base 3 until the insertion rod 50 is inserted into the slot 30. At this time, the clamping frame 5 can clamp and fix the base 1 on the mounting base 3. In addition, the mutual insertion and cooperation between the insertion rod 50 and the slot 30 can further limit the base 1 and fix it on the mounting base 3, greatly improving the stability and reliability of the base 1. Finally, by tightening the fastener 41 into the threaded hole 11 in the appropriate position, the rotation of the screw 4 can be restricted, ensuring the stability and reliability of the base 1 after installation, making the base 1 less prone to tipping risk.

[0032] When the clamping frame 5 gradually approaches the mounting seat 3 under the drive of the screw rod 4, the gear 42 will rotate synchronously under the drive of the screw rod 4, and the gear condition 12 will gradually move downward under the drive of the gear 42. The fixing rod 7 set at the bottom of the gear condition 12 can be gradually penetrated into the ground with relatively soft geology. By penetrating the fixing rod 7 into the ground, the wind and earthquake resistance of the base 1 can be further improved, and the base 1 can be more stable and reliable.

[0033] When the surface of the fence 2 needs to be cleaned, the surface of the fence 2 is first wetted, and then each cleaning seat 8 is moved back and forth along the length direction of the fence 2. The surface of the fence 2 can be wiped by the cleaning cotton 80, ensuring the cleanliness of the surface of the fence 2 and facilitating cleaning.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
