Description

Technical Field

[0001] The utility model relates to the technical field of foundation pits, in particular to a soil layer solidification construction structure. Background Art

[0002] The foundation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, an excavation plan should be formulated based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations.

[0003] At present, for deep excavations and those with nearby buildings, shotcrete sealing methods can be used. Existing shotcrete sealing methods include plain concrete spraying and mesh concrete spraying, both of which require cast-in-place operations. Not only does the construction take a long time, but it also pollutes the environment. At the same time, when spraying concrete, its rebound rate is relatively high - that is, the concrete material falls more after being sprayed onto the foundation pit slope. In addition, the foundation pit slope is not firm, and after spraying concrete, the self-weight of the foundation pit slope will increase, thereby causing the collapse of the foundation pit slope, which brings greater safety risks to the construction of shotcrete. For this reason, a soil layer solidification construction structure is proposed. Utility Model Content

[0004] The utility model is a soil layer solidification construction structure proposed to solve the shortcomings in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a soil solidification construction structure, including a solidification skin layer, a plurality of anchor rods are assembled on the top of the solidification skin layer; the solidification skin layer includes a surface layer, a connecting layer is fixedly connected to one side of the outer surface of the surface layer, and a dissolving layer is bonded to one side of the outer surface of the connecting layer.

[0006] Furthermore, the anchor rod member includes an anchor rod body, one end of which is fixedly connected to an extrusion circular plate, and the extrusion circular plate is in contact with the solidified skin layer. A mounting hole extending to the interior of the anchor rod body is provided on one side of the outer surface of the extrusion circular plate, and a fixing component is jointly installed between the mounting hole and the solidified skin layer. The anchor rod body can be inserted into the soil, which is conducive to overall laying.

[0007] Furthermore, the fixing assembly includes a fixed circular plate, and the fixed circular plate is attached to one side of the outer surface of the solidified skin layer. An expansion nail is fixedly connected to one side of the outer surface of the fixed circular plate, and the expansion nail penetrates the solidified skin layer. An expansion tube is sleeved on the outer surface of the expansion nail, and the expansion tube is located on the inner side of the mounting hole, which is conducive to connecting the solidified skin layer with the anchor rod.

[0008] Furthermore, the inner surface of the mounting hole is provided with anti-skid grooves to increase the friction of the inner surface of the mounting hole and prevent the expansion tube from slipping with the inner wall of the mounting hole.

[0009] Furthermore, the connecting layer is made of non-woven fabric, which has high strength and toughness.

[0010] Furthermore, the dissolving layer is made of water-soluble cloth, which is a non-woven lining cloth that can be dissolved in warm water and can be naturally decomposed after use, and does not pollute the environment like concrete.

[0011] Beneficial effects of the utility model:

[0012] When the utility model is in use, the soil solidification construction structure, through the provision of anchor rods, connecting layers and dissolving layers, the provision of anchor rods is conducive to the overall laying and avoids slipping. After the laying is completed, the connection layer is bonded to the soil particles by utilizing the characteristics of the water-soluble cloth, so as to achieve the purpose of sealing the excavated soil layer. Compared with shotcrete, the overall installation is assembled, which is convenient to install, can reduce the time consumed in construction, and has no environmental pollution. At the same time, it has little effect on the deadweight of the foundation pit slope, thereby reducing the construction risk. BRIEF DESCRIPTION OF THE DRAWINGS
