Description

A bamboo beam anchor support structure for slope

technical field

The utility model relates to a bamboo girder anchor support structure for slopes, which belongs to the technical field of construction engineering foundation pit support.

Background technique

In the construction process, the foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures are taken on the side wall of the foundation pit to prevent the slope from collapsing during the construction process. After the underground construction is completed, the foundation pit support will lose its function through backfilling and compaction of the backfill soil. Therefore, most of the foundation pit support is a temporary protection measure, so the safety reserve is small at the time of design.

Common foundation pit support methods mainly include row pile support, underground diaphragm wall support, cement retaining wall support, steel sheet pile support, soil nail wall spray anchor support and other forms. Most of the existing support forms are structures combining anchor cables and bolts with concrete, which has low material utilization rate, high support cost, and low construction efficiency, which affects the construction progress.

Utility model content

The purpose of the utility model is to provide a bamboo girder anchor support structure for a slope, which can improve the utilization rate of materials, reduce the waste of resources, and finally achieve the purpose of saving engineering costs under the condition of ensuring the safety of the foundation pit.

Technical scheme of the utility model:

A bamboo beam anchoring and supporting structure for a slope, including a foundation pit slope, on which a group of support beams fitted to the slope surface are arranged, and the support beams pass through bamboo anchor rods and anchor holes on the slope surface connect.

In the aforementioned support structure, the support beam is a slat made of composite bamboo boards, and its length is slightly smaller than the length of the slope of the foundation pit slope; the length direction of the support beam is provided with two rows of fixed holes arranged at equal intervals.

In the aforementioned supporting structure, the group of supporting beams is vertically arranged at equal intervals along the length direction of the slope surface, and a row of separating bamboo anchors is arranged between the two supporting beams.

In the aforementioned support structure, the anchor hole is perpendicular to the slope surface, the hole depth is not less than 1 meter, and the hole depth increases with the height of the anchor hole.

In the aforementioned support structure, the lengths of the bamboo anchor rods and the separated bamboo anchor rods are slightly greater than the depth of the anchor hole plus the thickness of the support beam.

Compared with the prior art, the utility model replaces traditional support structures such as concrete, anchor cables and anchor rods with slats made of composite bamboo boards and bamboo anchor rods. The structure is reasonable and has good mechanical properties, which can meet the needs of foundation pit walls lateral thrust stiffness. The resource waste is reduced, the project investment is greatly reduced, the construction is convenient, the construction efficiency can be effectively improved, and the purpose of speeding up the project construction progress is finally achieved.
