Embodiment Construction

[0027] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0028] A construction method of a trestle-type power transmission line installation base, the steps are as follows:

[0029] (1) Construction preparation, survey the construction site, determine the installation location of the trestle bridge, and transport the prefabricated trestle box to the construction site; see the attachment for the specific structure of the trestle box image 3 Attached Figure 4 , Including the lock piece 8, the support frame 9, the support plate 4 and the guardrail installation pipe 7. The main body of the trestle box body is a hollow cubic structure sealed at the bottom, and the upper lateral sides of the trestle box body are symmetrically fixed for connecting with the adjacent The tre...

Abstract

The invention relates to a construction method for a trestle type power transmission and transformation circuit mounting foundation. The construction method comprises the following steps of (1) preparing construction; (2) connecting a trestle box body; (3) mounting a connection plate; (4) paving a cover plate; (5) mounting a guardrail; (6) performing construction; (7) detaching a trestle after construction is finished. By the adoption of the belt-shaped trestle, the problem of difficulty in power transmission line construction in the regions such as a fish pond, a pool and a swamp is solved; construction is facilitated, and the capital investment is greatly saved; repeated use is realized, and the safety and the practicability are improved.

Description

Technical field [0001] The invention belongs to the technical field of electric power construction, in particular to a construction method for a trestle-type power transmission and transformation line installation base. Background technique [0002] The fish ponds, ponds and other places encountered in the construction of the current transmission line are inevitable. At present, the construction is carried out by filling the road or laying wooden bridges, and the trestle bridge is a fixed structure. Among them, the investment in filling roads is huge, which is almost close to the investment of the power facility itself, and the construction time is longer. The construction is cumbersome and complicated. The use of wooden trestle bridges reduces the investment, but the construction period is longer. Both trestle bridges are a one-time investment , Cost a lot of money. [0003] After searching, the following published patent documents of related technologies were found: [0004] An e...
