Embodiment Construction

[0025] In order to better understand the present invention, the present invention will be described in detail below in conjunction with specific examples.

[0026] see figure 1 , in order to overcome the shortcomings of the traditional construction technology in the background technology, the present invention provides an improved concrete cable trench construction process, design and manufacture steel formwork for combined assembly and use pull bolts to control the thickness of the cable trench, which can It is suitable for the construction of concrete cable trenches in substations (converters) of different voltage levels. The concrete technological process of the concrete cable trench construction technology of preferred embodiment of the present invention will be introduced in detail as follows:

[0027] Before the construction of the project, the overall planning shall be carried out according to the layout of the cable trench in the station and the design characteristics...

Abstract

The invention relates to a concrete cable channel construction process which comprises the following steps of: measuring, positioning and digging groove for earthwork; pouring and curing concrete on a cushion layer; binding rebar; pouring and curing concrete on a bottom plate; and assembling side wall steel formworks and installing embedded parts, wherein the side wall steel formworks are provided with split bolt holes and the inner and the outer steel formworks of a side wall are fixed by split bolts to determine a distance between the steel formworks at both sides of the side wall. According to the concrete cable channel construction process provided by the invention, the steel formworks are assembled to form the side wall, are tightly assembled and are difficult to deform, so that the concrete construction of a cable channel is formed in one step, a channel wall is flat and smooth and joints are flat without leaking paste after the formworks are disassembled, and the quality of the concrete surface of the channel wall of the cable channel can reach the fair-faced concrete quality level without secondary painting.

Description

【Technical field】 [0001] The invention relates to a concrete cable trench, in particular to a construction technique for a concrete cable trench. 【Background technique】 [0002] At present, there are two common methods for cable trenches in substations: one is plastering cable trenches on the surface of brick masonry; the other is cast-in-place concrete cable trenches. At present, concrete cable trenches are generally used for the main trench of substation cable trenches, and brick trenches are generally used for cable trenches with a trench width of 600 mm or less (including communication cable trenches); in addition, concrete cable trenches are often used for cable trenches under poor foundation conditions . [0003] In the construction of substation (converter) substation, the workload of the concrete cable trench in the substation is heavy, and its construction quality will directly affect the overall image of the substation project. In the construction process of engi...
