Abstract
The invention relates to the field of concrete construction, and discloses an in-station equipment foundation concrete foundation construction method which comprises the following steps: S1, positioning and setting-out measurement: measuring and positioning a construction site by adopting a total station, a theodolite, a level gauge, a box staff and a steel ruler, and carrying out plane axis positioning measurement setting-out and elevation control; s2, foundation excavation and transportation are conducted, specifically, earth and stone excavation generally follows the procedure from top to bottom, earthwork is conducted firstly and then stone excavation is conducted, groove cleaning is conducted after foundation excavation is completed, and foundation groove inspection needs to be conducted after excavation is completed; s3, reinforcing steel bar engineering is conducted, specifically, reinforcing steel bar connection is conducted firstly, the reinforcing steel bar connection mode is the combination of mechanical connection and binding lap joint, and quality inspection is conducted after reinforcing steel bar connection is completed; through cooperation of foundation excavation and transportation, bolt installation engineering, formwork engineering, concrete engineering and the like, excavation of the cableway foundation and cable erection can be conducted at the same time, limited construction time is fully utilized, and the overall construction time is guaranteed.
Description
technical field [0001] The invention relates to the technical field of concrete construction, in particular to a concrete foundation construction method for equipment foundations in a station. Background technique [0002] Concrete construction is to make and bind steel bars, place and fix formwork, use raw materials that meet quality requirements, mix, transport, pour, and maintain according to the specified ratio according to the requirements of the design drawings, and at the same time carry out the whole process of each link Quality control and inspection. [0003] The construction of the cableway foundation has to go through winter construction, and the construction period is short. To complete the construction of the project, the reasonable interspersion of the overall project is particularly important. The concrete foundation construction method of some in-station equipment foundations in the prior art cannot reasonably arrange the overall project, which makes the ov...
