Definitions

  • the method of the present invention adopts the following technical solution: A method for preventing termites from invading wooden poles, the method comprising the following steps:
  • a further improvement of the present invention is that the polymer film is a high density polyethylene film (HDPE).
  • HDPE high density polyethylene film
  • a further improvement of the present invention is that the thickness of the impervious material in the step (1) is 3-5 mm.
  • a further improvement of the invention is that the dose injected is equal to the average loss in the soil.
  • a wooden pole 5 is placed in the pit in which the high-density polyethylene layer is laid.
  • the diameter of the pole 5 is generally selected to be between 250 and 400 mm, and the present invention is preferably 300 mm. While the wooden pole 5 is placed, a drainage sand well and a vertical drainage riser are prepared, wherein, referring to Figures 2, 3 and 4, the drainage sand well and the vertical drainage vertical pipe are constructed as follows:
  • the drainage sand well can be tightened in the T s soil, and it takes longer without the sand well.
  • the specific time varies depending on the surrounding soil.
  • the drainage sand well and the vertical drainage vertical pipe can continuously remove water and moisture from the soil at the bottom of the pole to strengthen the soil and inhibit the survival of termites. Conditions of reproduction. In addition, the chance of mold damage to wooden poles can be greatly reduced.
  • Useful information for collecting wooden poles including the type of wooden pole, manufacturer name, year of production, chemical treatment method, pole size, wire structure set on the pole, number of conductors, conductor span and angle, utilization
  • the global positioning device measures the location after the placement of the wooden pole and the like;
  • MTCL Minimum Terminicide Concentration Level
  • MTCL is an arbitrary value, which is determined by the implementer. Below the minimum value, the chance of decay of the pole strength will increase, and once the pole begins to rot, in addition to using the external auxiliary support method to strengthen the wooden pole body, the pole It can't be repaired by itself, until the pole is rotten and can't be used, then it can be removed and replaced.
  • setting a high MTCL means that the frequency of re-spraying of termiticide is high, resulting in increased costs.
  • the concentration of the termiticide at this time is determined to be the lowest concentration MTCL.
  • Figure 9 shows the life cycle distribution curve of the pole, where the abscissa indicates the age of the wood pole, the ordinate indicates the number of poles, and the curve 22 is the original wood without the method of the present invention.
  • the life cycle distribution curve of the pole, the curve 20 is a life cycle distribution curve of the wooden pole after the method of the invention is used.
  • the curve is obtained by mathematical calculation based on the result of the above random multiple sampling test, and the more the sampled result is, the more refined the calculated value is. Indeed. Comparing the curve 20 and the curve 22 of FIG. 9 can clearly see that the life cycle of the wooden shield pole is effectively extended after using the method of the invention, and the termite is not used within 20 years after the wooden pole is used.
  • the electric pole is replaced by erosion, thereby greatly reducing the economic cost loss such as manpower and material resources caused by large-scale replacement of wooden poles.

Abstract

La présente invention concerne un procédé de prévention d'érosion d'un poteau en bois (5) par des termites, comprenant l'enveloppage d'un film polyéthyléne autour du poteau, l'installation d'un drain de sable et d'un conduit de drainage vertical (4) dans le sol en combinaison avec des agents termicides, la collecte d'information concernant le poteau, la mesure de la modification dans la concentration d'agents termicides dans le sol, l'analyse de la pluralité de données observées concernant le poteau et les agents termicides, le calcul de la détérioration de la solidité du poteau et la détermination de la dose minimale efficace d'agents termicides, pour réaliser une procédure de traitement dans l'application d'agents termicides. Le procédé peut assurer une prévention efficace d'érosion d'un poteau en bois par des termites sur une longue période.
