Description

Technical Field

[0002] The basement exterior wall is usually a retaining wall, which is made of vertical steel bars, horizontal steel bars, tie bars and concrete, and its upper end is fixed and the lower end is hinged. During the use of the basement exterior wall, it bears loads, including vertical loads and horizontal loads. The vertical steel bars bear the vertical loads, and the vertical loads are the weights transmitted from the upper part and the floor slabs of the basement structure and its own weight. The horizontal steel bars bear the horizontal loads, which are the lateral pressures generated by the ground live loads, lateral earth pressures, lateral groundwater pressures, etc.

[0003] However, when the existing basement exterior walls are in use, cracks are likely to occur. Once cracks appear in the basement exterior wall, its anti-seepage and waterproof requirements will be affected. Moreover, the basement exterior wall is under the extrusion of the soil layer for a long time, and the cracks on the basement exterior wall are likely to expand further, resulting in the easy infiltration of external groundwater into the basement through the cracks, affecting the normal use of the basement. Therefore, we propose a crack-resistant structure for basement exterior walls. Summary of the Utility Model
