Embodiment 1

[0045] A kind of prefabricated bamboo strip foundation pit slope protection, such as figure 1 , including a foundation pit 1, and the foundation pit 1 includes an upper soil mass 11, a platform 12 and a lower soil mass 13. Bamboo strips 2 are laid on the foundation pit 1 to protect the upper surface of the foundation pit 1 and prevent soil erosion on the surface of the foundation pit 1 .

[0046] Such as figure 1 with figure 2 There are several connection holes 21 around the bamboo strip 2, and bamboo nails 3 are inserted in the connection holes 21. The bamboo strip 2 is connected to the foundation pit 1 through the bamboo nails 3, and the bamboo strip 2 is easy to disassemble. The end of bamboo nail 3 is set as pointed, is convenient to the insertion of bamboo nail 3.

[0047] Such as figure 2 with image 3 , the bamboo strips 2 are provided with some fixing holes 22 near the connection holes 21, and the fixing holes 22 are pierced with tie wires 4, and the tie wires 4...

Embodiment 2

[0053] A construction method for slope protection of a prefabricated bamboo strip foundation pit, comprising the foundation pit 1 and bamboo strips 2 in the first embodiment.

[0054] 1. The production of the assembled bamboo strips 2: raw moso bamboo is used, and the bamboo strips 2 are formed after opening, drawing, cooking, drying, and weaving. The periphery of the bamboo strips 2 is provided with a connecting hole 21 of D50mm, and the specifications of the bamboo strips 2 The size generally adopts (length×width) 120cm×80cm, 120cm×60cm, 120cm×40cm, etc. One of the specifications of this series is convenient for assembly, and the other is convenient for a single worker to construct on site without the need for multiple workers to cooperate and assemble, saving construction costs .

[0055] 2. Excavate the upper soil body 11, trim the slope manually, and start laying the bamboo strips 2 on the slope top and slope surface. The bamboo nails 3 reach the soil layer, and the bamb...

Abstract

The invention relates to the field of foundation pit engineering, and discloses an assembled bamboo strip foundation pit protection slope. The assembled bamboo strip foundation pit protection slope comprises a foundation pit, wherein the foundation pit comprises an upper layer earth body, a platform and a lower layer earth body; bamboo strips are paved on the foundation pit; and the bamboo stripsare connected with the foundation pit through bamboo nails. After the foundation pit is used, the bamboo strips are removed to be recycled. The bamboo strips can be repeatedly used, and are low in price, so that the cost is reduced. During construction, noise is not generated, so that the pollution to the environment is little. When much rain water exists in the foundation pit, the rain water in the foundation pit can exude through the surface of the foundation pit, so that the content of the rain water in the foundation pit can be maintained to guarantee the structural strength of the foundation pit, and the foundation pit can be prevented from collapsing.

Description

technical field [0001] The invention relates to the field of foundation pit engineering, in particular to an assembled bamboo strip foundation pit slope protection and a construction method thereof. Background technique [0002] There are many forms of foundation pit support, and the support form should be selected according to the surrounding environment and geological conditions of the project during the construction process. The conventional foundation pit slope protection adopts the concrete spray anchor construction method, that is, the reinforcement mesh is bound on the slope surface of the foundation pit, the drainage holes are arranged, and then the concrete is sprayed under high pressure to form a reinforced concrete surface layer slope protection to prevent soil erosion on the slope surface. [0003] At present, the Chinese patent whose authorized notification number is CN103362131B discloses a kind of foundation pit support with composite bamboo reinforcement spra...
