Example Embodiment

[0016] The present invention will be described in more detail below in conjunction with the embodiments.

[0017] The present invention is a construction method for the concrete floor of a switchyard, including the following steps:

[0018] Step 1: Feed and mix in the order of crushed stone, cement, and sand. The continuous time from when all the materials enter the mixer to the start of the mixture is the shortest mixing time, and the actual mixing time is twice the shortest mixing time;

[0019] Step two, template installation,

[0020] For the steel formwork, first clean the steel formwork to ensure the smoothness of the top surface, and check the straightness of the formwork with small lines. The allowable deviation of local deformation is 3mm, and the maximum deflection of the middle part does not exceed 4mm. If it exceeds the above range, Adjust with hydraulic jack;

[0021] The wooden formwork is used in the local bends. The wood formwork uses 5cm thick dry red pine board, the w...

Abstract

A construction method of a switching station concrete floor comprises the steps of carrying out stirring; installing different formworks according to different modes; laying and vibrating concrete, wherein the concrete vibrates three times; collecting water and plastering the floor; carrying out fresh concrete joint cutting and crack sealing.

Description

technical field [0001] The invention relates to the field of switchyard construction, in particular to a construction method for a concrete ground of a switchyard. Background technique [0002] The switch yard is the place or place where the switch is placed in the power plant and the substation. Its surface carries electrical equipment, so it has high requirements for the ground construction. In the prior art, the ground construction of the switch yard is not separated from the ordinary concrete ground construction, so that the switch yard There are problems such as damaged cable trenches and ground depressions under the equipment foundation on the ground of the site. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a concrete ground construction method for a switchyard. [0004] In order to achieve the above object, the technical scheme adopted in the present inve...
