Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, it relates to a support structure suitable for deep foundation pits. Background Technology

[0002] As the depth of the foundation pit increases, simply using traditional support rods inserted from top to bottom around the pit is insufficient to prevent the soil from compressing inwards. This is mainly because the lower ends of the support rods are inserted shallowly, resulting in a large exposed portion. This reduces the soil interception capacity of the support rods near the top, weakening or eliminating the support effect and leading to poor overall performance. Therefore, this invention proposes a support structure suitable for deep foundation pits. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support structure suitable for deep foundation pits. This support structure is easy to build and can be recycled.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is as follows: The present utility model relates to a support structure suitable for deep foundation pits, including a T-shaped support plate and a support plate backing seat;

[0005] The T-shaped support plate includes a pressure plate extending vertically, and a support plate extending rearwardly is provided on the back of the pressure plate, with the support plate extending along the length of the pressure plate.

[0006] The guard plate support includes an upper plate and a lower plate. A support column connects the lower plate and the upper plate. The end of the guard plate support facing the T-shaped support plate is provided with a slot that extends horizontally inward. The slots are arranged at intervals along the length of the guard plate support. Both the upper and lower ends of the slots are connected to the outside. The support plate is inserted into the slot from top to bottom.

[0007] The present invention is further configured such that: the guard plate support seat has an insertion hole for vertical penetration, and a soil nail can be inserted into the insertion hole.

[0008] The present invention is further configured such that: a protrusion is provided on one bearing plate and a groove is provided on the other bearing plate between two adjacent T-shaped support plates.

[0009] The present invention is further configured such that the slot opening has a flared portion.

[0010] The present invention is further configured such that the support columns are arranged in a rectangular array between the upper plate and the lower plate.

[0011] The present invention is further configured such that the distance between two adjacent slots is equal.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. A support seat of a certain height is installed on the back side of the T-shaped support plate that extends upward, so that even if the T-shaped support plate is inserted into the soil at a shallow depth, the upper end will have a strong support capacity because of the support on the back side.

[0014] 2. The joint between two adjacent T-shaped support plates is blocked by the overlapping protrusions and grooves to prevent soil seepage.

[0015] 3. By inserting soil nails through the support seat of the guard plate, the support seat of the guard plate can be directly stabilized, and the T-shaped support plate can also be indirectly stabilized. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0022] Example 1

[0023] See Figures 1 to 4 As shown, the support structure applicable to deep foundation pits involved in this embodiment includes a T-shaped support plate 100 and a support plate backing seat 200.

[0024] The T-shaped support plate 100 includes a pressure plate 1 that extends vertically, and a support plate 2 that extends rearward on the back of the pressure plate 1. The support plate 2 extends along the length of the pressure plate 1.

[0025] The guard plate support 200 includes an upper plate 3 and a lower plate 4. A plurality of pillars 5 arranged in a rectangular array are connected between the lower plate 4 and the upper plate 3. The end of the guard plate support 200 facing the T-shaped support plate is provided with a slot 6 that extends horizontally inward. The slots 6 are equidistantly arranged along the length of the guard plate support 200. Both the upper and lower ends of the slots 6 are connected to the outside. The support plate 2 is inserted into the slots 6 from top to bottom.

[0026] Furthermore, the guard plate support 200 is provided with an insertion hole 7 that extends vertically through it, and a soil nail 8 can be inserted into the insertion hole 7.

[0027] In this implementation plan, the protective plate support seat 200 is first arranged to the bottom of the foundation pit, so that it is close to the inner wall of the foundation pit and the slot 6 faces the inner wall of the foundation pit. Then, T-shaped support plates 100 are inserted one by one at each slot position. The T-shaped support plates 100 are inserted from top to bottom, until the bottom part is inserted into the soil at the bottom of the foundation pit. During the insertion, the support plate 2 is inserted into the slot 6 for insertion positioning and guidance.

[0028] The insertion hole 7 and the soil nail 8 are used as a reinforcement support seat 200 for the protective plate.

[0029] Example 2

[0030] See Figures 1 to 4 As shown, the support structure applicable to deep foundation pits involved in this embodiment is further configured, based on embodiment 1, with a protrusion 9 provided on one bearing plate and a groove 10 provided on another bearing plate between two adjacent T-shaped support plates 100.

[0031] In this embodiment, the protrusions and grooves are used to block the gaps between adjacent assembled pressure plates 1, preventing soil seepage.

[0032] Example 3

[0033] See Figures 1 to 4 As shown, the support structure for deep foundation pits involved in this embodiment is further configured, based on embodiment 1, that the slot 6 has a flared opening (not marked).

[0034] In this embodiment, the flared part is used as an installation guide to facilitate the side insertion of the support plate 2 into the slot 6.

[0035] The support structure for deep foundation pits disclosed in this utility model features a support base of a certain height installed on the back side of an upwardly extending T-shaped support plate. This ensures that even when the T-shaped support plate is inserted into the soil at a shallow depth, the upper part has strong support capacity due to the support on the back side. The overlapping protrusions and grooves between adjacent T-shaped support plates prevent gaps and soil seepage. Furthermore, the soil nails inserted through the support base directly stabilize the support base and indirectly stabilize the T-shaped support plate. The overall structure is functionally complete and highly practical.
