Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit engineering, and particularly relates to a concrete support beam column for a deep foundation pit. Background Technique

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. During the excavation process of the foundation pit, the deformation of the surrounding soil will be caused, which will affect the surrounding buildings and underground pipelines. Seriously, it will endanger the normal use of the foundation pit. Especially for deep foundation pits, soil deformation and landslides are more likely to occur. In order to prevent this situation, a support structure will be added during the construction of deep foundation pits to stabilize the foundation pit.

[0003] Due to the large excavation depth of deep foundation pits, the deeper the foundation pit, the worse the stability of the internal soil layer. Therefore, the difficulty of burying support beam columns in deep foundation pits also increases. After the support beam columns are buried inside the foundation pit, they are easily affected by the collapse or vibration of the local soil layer in the foundation pit, resulting in the phenomenon of offset or overturn of the support beam columns.

[0015] (III) Beneficial effects

[0016] The utility model provides a concrete support beam column for a deep foundation pit, which has the following beneficial effects:

[0017] For the concrete support beam column for the deep foundation pit, by providing a cement base with a shock absorption function, while fixing the support beam column, it can also provide a certain shock absorption capacity for the support beam column.

Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 、 3 shown, the present utility model provides a technical solution: a concrete support beam-column for a deep foundation pit, including a foundation pit 1, a cement base 2 is laid at the bottom of the foundation pit 1, an installation groove 3 is opened on the cement base 2, and a support beam-column 4 is installed in the installation groove 3.

[0024] As Figure 3 shown, a shock-absorbing component 5 is arranged in the installation groove 3. The shock-absorbing component 5 includes at least two layers of steel plates 51, and a rubber damping pad 52 is clamped between the two layers of steel plates 51. The purpose of setting the steel plates 51 is to bear the load of the support beam-column 4 through the steel plates 51, so that the rubber damping pad 52 with shock-absorbing effect can be prevented from failing due to overloading.

[0025] As Figure 1 shown, an installation seat 6 is arranged on the outer periphery of the bottom of the support beam-column 4. The installation seat 6 is fixed on the cement base 2 through fixing bolts 7. A gap is reserved between the installation seat 6 and the cement base 2, and multiple groups of first rigid springs 8 (made of high-strength steel) are arranged at this gap.

[0026] As Figure 2 shown, steel plate locking rings 9 and locking ring seats 10 are arranged at intervals on the support beam-column 4. The lock catch of the steel plate locking ring 9 is clamped in the middle of the locking ring seat 10. An outer support device is also arranged on the locking ring seat 10. The outer support device is respectively fixed to the two side walls of the foundation pit 1, and a triangular structure is formed between the outer support device and the two side walls of the foundation pit 1. This triangular structure can ensure the stability between the support beam-column 4 and the foundation pit 1 in the horizontal direction.

[0027] As Figure 2 shown, the outer support device includes two layers of support plates 11 up and down. The stability of the two side support plates 11 is stronger. The two layers of support plates 11 are respectively located on the upper and lower sides of the steel plate locking ring 9, and multiple groups of second rigid springs 12 (made of high-strength steel) are arranged between the two layers of support plates 11.

[0028] As Figure 2As shown, a stable support assembly is provided between adjacent external braces. The stable support assembly includes a support platform 13 sleeved outside the support beam-column 4. Both the upper and lower sides of the support platform 13 are fixed to the external braces through inclined struts 14. A triangular structure is formed between the inclined struts 14 and the external braces. This triangular structure can ensure the stability of the support beam-column 4 in the vertical direction. At the same time, the stable support assembly can connect the scattered external braces into a whole to resist the adverse effects brought by local soil layer collapse.

[0029] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] First, the support beam-column 4 is lifted above the cement base 2 by a crane tool, and then the support beam-column 4 is placed into the installation groove 3. The bottom of the support beam-column 4 abuts against the shock-absorbing assembly 5, and then the support beam-column 4 is fixed to the cement base 2 through the fixing bolts 7.

[0031] When subjected to external vibration, the shock-absorbing assembly 5 can provide shock absorption for the support beam-column 4. Secondly, with the help of the first rigid spring 8 and the second rigid spring 12, the seismic resistance of the support beam-column 4 can be further enhanced.

[0032] The support beam-column 4 is restricted by multiple groups of external braces and the stable support assembly at the same time, and can be firmly restricted in the predetermined installation position. Even if there are problems such as local soil layer peeling or collapse, there are still multiple groups of other external braces and the stable support assembly to ensure the stability of the support beam-column 4.

[0033] In summary, for the concrete support beam-column used in deep foundation pits, by setting a cement base with a shock-absorbing function, while fixing the support beam-column, it can also provide a certain shock-absorbing capacity for the support beam-column. Therefore, it can reduce the adverse effects brought by external vibration to the support beam-column and improve the stability of the support beam-column in a vibrating environment. Further, by setting multiple groups of external braces and the stable support assembly, the support beam-column can be firmly locked on the cement base. In this way, even if local soil layer peeling or collapse occurs, the support beam-column can still be ensured to be stable and immovable, greatly reducing the destructive force of external factors on the stability of the support beam-column.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
