[0033] Example 1.

[0034] The geotechnical protection device includes a protection unit and a support unit. The protection unit includes at least a protection plate 1, and the support unit includes at least a support assembly. The support assembly includes an installation sleeve 3 and a telescopic support rod 2.

[0035] There are two protective plates 1, namely the left plate and the right plate. The left plate and the right plate are respectively attached to the two sides of the earthwork tunnel. According to the situation of the tunnel, the installation sleeves 3 are set in appropriate positions on the two protective plates 1. According to the position of the installation sleeves 3 and the distance between them, the support rods 2 are telescopically adjusted so that the two ends of the support rods 2 are respectively connected to the installation sleeves 3 to support the protective plates 1.

[0036] The support components are multiple and arranged at intervals between each other.

[0037] This embodiment provides a protective device for tunnel construction. The protective plate 1 is closely attached to both sides of the tunnel, which can prevent soil and rocks from sliding down the sides of the tunnel and also block soil from sliding down outside the tunnel, thus reducing construction hazards.

[0038] In this embodiment, the protective plate 1 can be made from local materials, such as color steel plate or other metal plates. The protective plate 1 can be inserted into the soil at the bottom of the tunnel, or wooden boards can be placed at the bottom of the protective plate 1 to prevent it from sinking into the soil.

[0039] like Figures 1 to 7 As shown, support components are respectively installed on the upper and lower sides of the protective plate 1 to provide support. The specific placement of the support components can also be considered based on factors such as the depth of the tunnel and the height of the excavated soil. In special cases, an additional set of support components can be installed near the middle of the protective plate 1, but the support components at the bottom of the tunnel should be arranged as low as possible. The support components are arranged with spacing between them so as not to obstruct construction when it is necessary to hoist construction materials such as pipes, cables, and mortar.

[0040] The support rod 2 adopts a threaded telescopic design. Both ends of the support rod 2 are inserted into the mounting sleeves 3 on both sides. The mounting sleeves 3 can fix the support rod 2 in any way.

[0041] In this embodiment, the left and right plates located on both sides of the tunnel may not be able to be aligned, which may result in slight misalignment. In this case, a ball bearing mechanism 4 can be added to allow the mounting sleeve 3 to swing to a certain extent, which facilitates the installation of the support rod 2.

[0042] When using this embodiment, the excavated soil can be piled up outside the tunnel where the protective plate 1 is installed. However, it should be noted that the protective plate 1 in this embodiment does not cover the entire tunnel. Soil should not be piled up outside the tunnel where the protective plate 1 is not installed.

[0043] In the embodiment, the welding process is used in large quantities, the base 5 of the ball bearing mechanism 4 is welded and installed, but the frequent welding cutting can easily damage the protective plate 1, or at least cause the protective plate 1 to have too many parts on the surface, and the service life is reduced. At the same time, in order to increase the strength of the protective plate 1, metal pipes 6 are arranged on the opposite inner sides of the protective plate 1, and the ball bearing mechanism 4 is welded on the metal pipes 6. It is more convenient to cut and polish the opposite protruding metal pipes 6.

[0044] Embodiment two.

[0045] The embodiment aims to reduce the complexity of the structure and reduce the number of parts.

[0046] When a long length of protective plate 1 needs to be installed in the tunnel, it will cause too many support rods 2, otherwise it cannot provide a good support effect. As shown in Figures 8 to 10 The high-strength metal cross 7 is provided, which is made of high-strength steel, and the high-strength metal cross 7 is provided with a male head 8 facing the protective plate 1 and a female sleeve 9 away from the protective plate 1. The male head 8 is inserted into the mounting sleeve 3, and the female sleeve 9 is used instead of the mounting sleeve 3 to install the support rod 2. Two sets of high-strength metal cross 7 are provided, and the high-strength metal cross 7 can adopt a bent shape (not shown) to fit the protective plate 1 as much as possible, and partially replace the support rod 2 to provide support, thereby reducing the number of support rods 2 used.

[0047] In the embodiment, horizontal top legs 10 can be used to avoid the high-strength metal cross 7 being forced to bend, the leg frame 11 of the horizontal top leg 10 is welded on the high-strength metal cross 7, and the top plate 12 supports the protective plate 1. The horizontal top leg 10 is designed integrally with the high-strength metal cross 7, which improves the support effect on the basis of maintaining the effect of reducing the number of parts.

[0048] Embodiment three.

[0049] The embodiment provides a series of protective measures to increase the service life, in which the dust cover 13 is rotated at both ends of the support rod 2 through the retainer 14, and the rotation of the dust cover 13 is coaxial with the support rod 2, which does not affect the rotation and expansion of the support rod 2 itself. The recess can be formed at both ends of the support rod 2, and the retainer 14 is rotated in the recess through the connecting piece. The dust cover 13 covers the threaded connection of the support rod 2, avoids dust falling on the threaded connection, and also has a partial waterproof effect.

[0050] In the embodiment, a waterproof roof is also installed on the metal pipe 6, which can be welded on the metal pipe 6 by welding process, and the waterproof roof can adopt any scheme, such as a scheme of metal frame plus waterproof cloth.

[0051] In the embodiment, the multifunctional welding platform 15 is arranged directly below the protective plate 1 and above the ball bearing mechanism 4, and the anti-kicking plate 16 with a length suitable for the distance between the left plate and the right plate can be selected and welded on the multifunctional welding platform 15. Meanwhile, the multifunctional welding platform 15 can be arranged with a circuit to supply power for construction, such as power supply for lighting devices of the waterproof ceiling.
