Substation ground construction method and construction equipment
The invention relates to a transformer substation ground construction method and equipment, and relates to the technical field of transformer substation ground construction.The transformer substation ground construction method comprises the following construction steps that a construction position is determined through lineation, accumulated water on the ground is cleaned, and a base layer is flattened; checking whether impurities exist in the quality of the backfill soil, whether the particle size meets the specification and the water content of the backfill soil; laying soil layer by layer; a soil layer is tamped, at least three times of tamping are conducted on each layer, tamping needs to be conducted in a one-tamping and half-tamping mode, tamping is conducted in a connecting mode, in a line-to-line connecting mode and in a crisscross mode, and laid soil in the corners of each layer of the foundation pit is tamped repeatedly through tamping equipment; after each layer of filled soil is tamped, cutting ring sampling is carried out, the mass density of dry soil is measured, the tamped compactness of each layer is checked, and after the requirement is met, soil paving of the upper layer is carried out; and after finishing, leveling, acceptance and tamping are completed, surface wire drawing and leveling are conducted, the places exceeding the standard elevation are leveled according to wires, and the places lower than the standard elevation are filled with soil and tamped again. The device has the effect of improving the compactness of the corners in the foundation pit during layered tamping.
本申请涉及一种变电站地面施工方法及施工设备，涉及变电站地面施工技术领域，该一种变电站地面施工方法，施工步骤如下：划线确定施工位置，对地面进行清理积水、平整基层；检验回填土的质量有无杂物，粒径是否符合规定，以及回填土的含水量；分层铺土；夯实土层，每层至少夯打三遍，打夯应一夯压半夯，每夯均为相接，行行相连，纵横交叉，每层基坑角落内的铺土使用夯实设备反复进行夯实；每层填土夯实后，进行环刀取样，测出干土的质量密度，检验每层夯实的密实度，达到要求后，再进行上一层的铺土；修整找平验收，夯实完成后，进行表面拉线找平，凡超过标准高程的地方，依线铲平，凡低于标准高程的地方，补土再次进行夯实。本申请具有提高基坑内的角落在分层夯实时的密实度的效果。
