40m Electric Power Horizontal Directional Drilling Machine/Hdd Rig For Underground Pipe

Machine Introduction

RCHD-40E small hydraulic thrust boring machine is a special pipe jacking machine for water conservancy projects. The characteristics of water drill pipe jacking machine are small and flexible. Water drill pipe jacking machine has changed the working efficiency of hydraulic pipe jacking machine. The general soil jacking speed of water drill pipe jacking machine is m/5 seconds, which is more than ten times the speed of ordinary hydraulic pipe jacking. The jacking rod of water drill pipe jacking machine adopts high-strength water-injectable jacking rod. During the working process of water drill pipe jacking machine, water injection is used to change the residual soil into mud flow out, thereby reducing the friction of jacking force. Water drill pipe jacking machine also changes the toughness of soil.

Technical Parameters

Machine Advantages

1.alloy drill bit:

The front of the water drill pipe jacking machine is equipped with an alloy drill bit, even if it is rock, floor slab, non-metallic solid objects, it can pass smoothly. When encountering solid objects, it will not deviate or slip, but it will directly affect the process speed. Please distinguish whether there are other objects underground when using it. In general, the water drill pipe jacking machine can use a straight jacking method. Note: (In the case of small diameter and short length) In general, when the diameter is less than 30-50MM and the length is not more than 49M, direct jacking can be used without water injection, which greatly saves working time.

2.automatic pulling back function:

The water drill pipe jacking machine uses a universal joint to pull back the pipe material. During the rotation and pulling back process, the pipe can be pulled back smoothly in the static process. In addition, the soil conditions in the pipe are taken into consideration during the development and production of the machine. When pulling back, the front part of the universal joint and the pipe is connected. A spiral excavation device is used. The remaining soil during drilling can be pulled out at the same time as the pipe with a rotating excavator. The small underground pipe jacking machine adopts an automatic travel design and automatic pulling back function. The main machine is connected to the gearbox in one piece.

3.Main Structure:

The main structure of the water drill pipe jacking machine equipment group consists of four parts. (1) The main part of the water drill pipe jacking machine: mainly composed of two double-acting hydraulic cylinders. (2) A hydraulic pump station of the water drill pipe jacking machine, which is equipped with a diesel engine pump station and an electric motor pump station respectively. (3) Two supporting plates for the water drill pipe jacking machine, which are used to fix the machine and support the pit wall. (4) The top rod and pull head of the water drill pipe jacking machine: their function is to push in and pull back to expand the hole.

Application

RCHD-40E horizontal directional drilling machine is widely used in natural gas transformation, tap water transformation, sewage engineering, small sewage, pipeline installation, road trenchless water pipe transformation and other projects to open up the use, with fast drilling, not afraid of hard soil characteristics, so that construction is fast and labor-saving, drilling smooth and flat.
