Problems solved by technology

At present, there are many specifications of non-excavation reamers on the market, such as extrusion type, cutting type, spinning type, barrel type, etc., most of which are similar and use different reamers for different soil layers. Existing non-excavation reamers are all integrated, and the size cannot be adjusted. When purchasing, customers need to purchase a whole set of reamers of different sizes to meet the needs of different sizes of apertures, which often leads to the need for more Space to store the reamer, not convenient to carry
And since a reamer is required for each size, the equipment cost is high

Abstract

The invention discloses a novel geological stacked hole reamer. The novel geological stacked hole reamer comprises a connecting rod and a plurality of tower body pieces. The connecting rod is providedwith a main water channel in the center axial direction. The tower body pieces are provided with through holes. The through holes and the tower body pieces are coaxial. The plurality of tower body pieces are detachably and tightly arranged on the connecting rod through the through holes of the tower body pieces in a sleeving mode in sequence. The novel geological stacked hole reamer provided by the invention is adjustable in size, long in service life, easy to replace and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of drilling tools, in particular to a novel geological split reamer. Background technique [0002] With the rapid development of the pipeline transportation industry, the drilling and reaming operations of pipeline holes crossing rivers, lakes, highways, railways and even mountains are gradually increasing, and the use of crossing reamers is becoming more and more frequent. Pipeline laying is divided into two types: excavation and non-excavation. Non-excavation pipeline laying adopts guided and directional drilling methods. It only needs to occupy a very small surface area and will not hinder traffic or damage green areas. vegetation and more. At present, there are many specifications of non-excavation reamers on the market, such as extrusion type, cutting type, spinning type, barrel type, etc., most of which are similar and use different reamers for different soil layers. Existing non-excavation reamers a...
