Description

Technical Field

[0001] The utility model relates to the technical field of surface settlement monitoring, in particular to a surface observation point protection device suitable for soft soil areas. Background Art

[0002] A surface settlement observation point is a monitoring point buried in the ground for observing uneven surface settlement. At present, urban subway shield construction, super-deep foundation pit excavation, and large-scale building (structure) construction all require monitoring of the surrounding environment surface. In existing new project construction, the surrounding environment ground is often undisturbed soil or miscellaneous fill soil, and the environment is relatively harsh. During the surface settlement monitoring process, the surface points need to be protected. Currently, the most commonly used method is to add a surface point protection cover on the upper part of the surface point. Under special soft soil geological conditions, the surface point protection cover often sinks over time and cannot play a better protective role. At the same time, there is a phenomenon that the cover plate is not easy to open after the protection cover sinks. In order to make up for the shortcomings of the existing protection cover, a surface observation point protection device suitable for soft soil areas is needed. Utility Model Content

[0003] In order to overcome the problem that the protective cover of the existing surface observation point protection device in soft soil areas is prone to sinking and cannot play a better protective role, and the cover plate is difficult to open after the protective cover sinks, the utility model provides a surface observation point protection device suitable for soft soil areas, so that the protective cover is more suitable for the protection work of surface points in soft soil areas.

[0004] The utility model adopts the following technical solutions:

[0005] A surface observation point protection device suitable for soft soil areas consists of a base and a protection cover. The base body is cylindrical and a skirt-shaped wing plate is arranged at the bottom.

[0006] Furthermore, an extension piece is provided between the base and the protective cover.

[0007] Furthermore, the upper portion of the base is provided with an internal thread which matches the external thread at the lower portion of the extension piece.

[0008] As a preferred solution, a snap ring is provided on the inner side of the upper portion of the base, and the protective cover is provided with a chain connected to the base.

[0009] As a preferred solution, a snap ring is provided on the inner side of the upper portion of the extension member, and the protective cover is provided with a chain connected to the base.

[0010] As a preferred solution, the end of the chain is provided with a manual buckle which is detachably connected to a snap ring.

[0011] The beneficial effects of the utility model are:

[0012] The main part of the base is cylindrical, and a skirt-shaped wing plate is provided at the bottom, which can effectively prevent the protective cover from sinking in soft soil areas. An internal thread is provided on the upper part of the base, which matches the external thread on the lower part of the extension. When the geological conditions are too poor and cause the protective cover to sink seriously, the extension can be used to lengthen and raise the protective cover. The protective cover is connected to the lower structure with a chain, which can effectively prevent the cover from being unable to open after the protective cover sinks compared to the flip-top protective device. A snap ring is provided on the inner side of the upper part of the base and the extension. The manual snap buckle at the end of the protective cover can be stuck on the upper part of the snap ring when in use, which is convenient for replacement when the upper protective cover is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the content of the utility model easier to understand, the utility model is further described in detail according to specific embodiments and in conjunction with the accompanying drawings.

[0017] To illustrate the features of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] See also Figure 1 The embodiment of the utility model provides a surface observation point protection device suitable for soft soil areas, which consists of a base 7, an extension piece 4 and a protective cover 1. The main part of the base 7 is cylindrical, and a skirt-shaped wing plate 8 is provided at the bottom. An internal thread 6 is provided on the upper part, which matches the external thread 5 at the lower part of the extension piece 4. A clamping ring 2 is provided on the inner side of the upper part of the base 7 and the extension piece 4, and a chain is provided at the lower part of the protective cover 1. The end is a manual buckle 3, which can be clamped on the upper part of the clamping ring 2 when in use.

[0020] The main part of the base 7 is cylindrical, and a skirt-shaped wing plate 8 is provided at the bottom, which can effectively prevent the protection device from sinking in soft soil areas.

[0021] An internal thread 6 is provided on the upper portion of the base 7, which matches the external thread 5 on the lower portion of the extension member 4. When the geological conditions are too poor and cause the protective device to sink seriously, the extension member 4 can be used to lengthen and raise the protective device.

[0022] The protective cover 1 is connected to the lower structure by a chain, which can effectively prevent the cover plate from being unable to open after the protective cover 1 sinks compared to the flip-top protective device.

[0023] A clamping ring 2 is provided on the inner side of the upper part of the base 7 and the extension member 4. The manual buckle 3 at the end of the protective cover 1 can be clamped on the upper part of the clamping ring 2 when in use, so that it is convenient to replace the upper protective cover after it is damaged.

[0024] The method of using this embodiment is:

[0025] When in use, first complete the layout of the internal steel bars at the surface point, and backfill the hole with sand and gravel according to the specifications. Then reserve a hole at the top according to the size of the protective device base 7, and place the base 7 so that the top of the base is slightly lower than the ground. After the base 7 is placed, start backfilling the soil on the upper part of the skirt wing plate 8, and compact it after backfilling to ensure the integrity of the base 7 and the surrounding soil. Finally, manually snap the end buckle 3 of the protective cover 1 onto the upper part of the clamping ring 2 to complete the connection. After the connection, cover the protective cover 1 on the upper part of the base 7.

[0026] When the base sinks with the passage of time, the protection device can be lengthened and raised by connecting the extension piece 4 with the base 7. First, open the manual buckle 3, remove the protection cover 1, rotate the extension piece 4 to threadedly connect with the base 7, and then clamp the manual buckle 3 on the upper part of the clamping ring 2 of the extension piece 4 to complete the connection. If the protection cover is damaged during use, the protection cover 1 can be replaced in the same way.
