Description

A construction method for erecting cement utility poles against tipping

technical field

The invention belongs to the field of electric power construction, and relates to a construction method for erecting a utility pole, in particular to a construction method for erecting a cement utility pole against dumping.

Background technique

In the process of power maintenance, it is often encountered that the utility pole is tilted due to wind, rain, weather and other reasons. Once the utility pole is tilted, it is easy to cause a pull on the transmission line, and in severe cases, the transmission line will be broken, causing a large-scale power outage.

For the erection of cement poles in saline-alkali areas, in addition to weather factors, geological factors must also be considered. In practice, although the bottom of the utility pole is poured with high sulfate-resistant cement, dense longitudinal cracks still appear. If the stability problem of cement utility poles erected in saline-alkali land cannot be solved, the long-term safe operation of transmission lines cannot be guaranteed. Therefore, a cement utility pole with strong stability, prolonging the service life of the utility pole, and anti-dumping is invented. It is very necessary to erect construction methods in saline-alkali areas.

By searching the published patent documents, no published patent documents identical to the present patent application have been found.

The present invention solves its technical problem and realizes by taking the following technical solutions:

A construction method for erecting cement utility poles against tipping, characterized in that it comprises the following construction steps:

1) Excavation of the foundation pit: According to the drawings, excavate the foundation pit at the position where the utility pole is to be erected. The depth of the foundation pit is at least three tenths of the height of the utility pole, and the length and width are three times the diameter of the utility pole;

2) Laying of the isolation layer: set the isolation layer cement with a thickness of 0.1m on the bottom and inner wall of the foundation pit, and carry out maintenance work after soaking in water for two days;

3) Laying of the installation framework: After the isolation layer is completely air-dried, lay the installation framework in the middle of the foundation pit with the isolation layer, and connect the bottom plate of the installation framework with the bottom surface of the foundation pit with the isolation layer through installation nails;

4) Waterproofing and erection of utility poles: Put a plastic barrel on the bottom of the utility pole, and seal the seam between the plastic sleeve and the utility pole with a sealing rubber ring, thereby completing the waterproof treatment of the utility pole; the wires that have been waterproofed The pole is inserted into the pole installation opening of the installation framework by the lifting device, so that the bottom of the pole abuts against the bottom plate of the installation framework, and the installation hoop is set on the upper part of the installation opening of the pole on the pole, and in the four directions of the installation hoop Lead out four traction ropes obliquely from the top, and the four traction ropes are respectively fixed on the threading holes set on the bottom plate, thus completing the preliminary erection work of the utility pole;

5) Soil filling and compaction: Fill non-corrosive soil into the foundation pit where the utility poles have been erected. After compaction, the erection of the entire utility poles will be completed.

And described installation frame is made of base plate, well-shaped frame and connecting frame, and described base plate and well-shaped frame are relatively arranged up and down, and connecting frame is vertically arranged between well-shaped frame and base plate, and this connecting frame is arranged on At the four intersections of the well-shaped frame, the base plate is provided with epoxy-coated steel plates on the surface, and the four corners of the base plate are provided with threading holes for installing traction ropes. It is composed of steel bars coated with epoxy resin, and the opening formed in the middle of the well-shaped frame is the installation opening of the utility pole.

Moreover, the height of the connecting frame is one tenth of the height of the utility pole.

Moreover, the cement of the isolation layer is slag cement or pozzolanic cement or fly ash.

Advantage and positive effect of the present invention are:

1. The anti-dumping construction method of cement utility poles, through the isolation of the isolation layer, prevents the salt content of the saline-alkali soil from rising, causing erosion of the built-in frame or cement poles; On the one hand, it can play a role in stabilizing the utility poles, and on the other hand, it also facilitates the erection of the utility poles; when the soil is rammed, ordinary non-corrosive soil is used, which is convenient to obtain and low in cost.

2. The design of the present invention is scientific and reasonable, and has the advantages of simple structure, convenient lighting, improved comfort in use, improved repair efficiency, labor and labor saving, and easy implementation. It is a highly innovative concrete utility pole anti-dumping erection Construction method.

Detailed ways

Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

A construction method for erecting concrete utility poles against tipping, which is innovative in that it includes the following construction steps:

1) Excavation of the foundation pit: according to the drawings, excavate the foundation pit at the position where the utility pole is to be erected. The depth of the foundation pit is at least three tenths of the height of the utility pole 4, and the length and width are three times the diameter of the utility pole;

2) Laying of the isolation layer: Set the isolation layer 2 cement with a thickness of 0.1m on the bottom and inner wall of the foundation pit, and carry out maintenance work after soaking in water for two days;
