Water Well Drilling Methods

It`s not surprising that water well drilling is an ancient undertaking. About 8,000 years ago, the first water wells were hand dug to supply a safe, clean and reliable water source for the earliest civilizations. Our need for water has not changed, but well drilling technology has come a long way since then. In some areas of the world, manually digging a water well is still the chea

Do you know the principle of crane telescopic boom?

The boom of truck crane is the most important part of crane. The crane uses the pulley block at the top of the boom to support the winch wire rope to suspend heavy objects, and changes the lifting height and working radius according to the length and Angle of the boom. Although the role of the boom is to suspend and transport objects, different boom structures and technologies make the performance and efficiency of the crane is very different. 1. Truck crane boom structure The boom of the truck crane generally includes the main arm and the auxiliary arm. There are two typ

Common welding methods for steel structure members

Welding is the process of combining atoms (molecules) of two separated objects to form a whole with the help of energy. The welding method can not only connect metal materials, such as steel, aluminum, copper, titanium, etc; It can also connect nonmetals, such as plastics and ceramics; It can even solve the connection between metal and nonmetal, which is collectively referred to as engineering welding. The structure made by welding method is called welding structure, also called engineering welding structure. According to the object and purpose, it can be roughly divided into four types

What are the regulations for the weld connection of steel structure, and what are the requirements for the weld size of lap welding, plug welding and slot welding?

1. The stress and structural welds of structural members in the steel structure can be butt welds, fillet welds, combination welds of butt and fillet welds, plug welds and slot welds. The butt welds of important connections or with equal strength requirements should be penetration welds, and the partial penetration welds can be used for thicker plates or without penetration. 2. The groove form of butt weld should be selected according to the plate thickness and construction conditions according to the current national standard Code for Welding of Steel Structures GB 50661. 3.

What do you know about steel structural parts?

Today we will talk about steel structural parts (hereinafter referred to as steel structural parts). You may be familiar with steel structural parts. You also know that steel structural fittings include anchor bolts, embedded panels, welded floor cages... What do you know about steel structural parts? Steel structure engineering is one of the main types of building structure. It is one of the more common structural forms in modern architectural engineering. China is the first country to manufacture load-bearing structures with iron, and steel structural engineering is mainly made of ste

Loader maintenance skills

After the loader factory, there is generally a period of about 60 hours of run-in period (some called run-in period), run-in period is according to the technical characteristics of the loader in the early use of provisions. The run-in period is an important link to ensure the normal operation of the loader, reduce the failure rate and extend its service life. Some users due to the lack of common sense of the use of the loader, the construction period is tight, or eager to obtain profits as soon as possible, ignoring the special technical requirements of the new machine run-in period.

How to choose an economically appropriate TBM

As an important node of traffic network, tunnel plays an important role in the field of traffic and transportation. However, the construction and construction of tunnels is extremely vulnerable to multiple factors, especially in the geological environment. Geological environment quality is very important to tunnel construction. During excavation and construction, engineers must have a good understanding of the geological composition. From the point of view of construction, the choice of tunneling equipment and construction method is the key to make the whole scheme. Geological c

Classification of pipe jacking machines

1. Sort by the principle of balance It can be divided into mud-water balancing pipe jacking machine, soil pressure balancing pipe jacking machine, mud enrichment type shield pushing machine and multi-function pipe jacking machine. Mud-water balancing pipe jacking machine is the most widely used one at present. Its main advantages are as follows: (1) Suitable for a wide range of soil, including soft soil, clay, sandy soil, gravel soil and hard soil. (2) Strong crushing capacity, large crushing size and large quantity. (3) with an independent water injection gr

Four kinds of construction techniques for bored pile with rotary drilling rig

Rotary drilling rig is a kind of construction machinery suitable for hole-forming operation in building foundation engineering. It is widely used in municipal construction, highway bridge, high-rise building and other ground foundation construction projects. With different drilling tools, it is suitable for dry (short spiral), wet (rotary bucket) and rock formation (core drill) hole-forming operation. Rotary drilling rig has large installed power, large output torque, large axial pressure, and flexibility, High construction efficiency and multi-function. The rotary drilling rig is suita

Principle and advantage of hydrostatic pile driver

Working principle: Construction process: measurement and positioning → pile driver in place → pile lifting and inserting → pile body aligned with middle injection → static driving pile → pile connecting → static driving pile again → pile feeding → pile pressing termination → acceptance → pile driver handing over. Function description: 1. Civilized construction -- low noise, no pollution, clean site, low labor intensity. 2. High efficiency of piling - hundreds of meters per shift (8 hours). 3. Good quality of pile - the eight-way design of

This paper introduces some problems that should be paid attention to in the process of using drill bit of water well rig

Drill bit plays an important role in the drilling process of water well rig. The quality of drill bit directly affects the drilling efficiency and the quality of borehole formation. Therefore, we need to pay attention to bit selection and usage. During the drilling process, the operator should pay attention to the drilling use of the drill to make the drill more productive. Several aspects should be paid attention to in water well drill bit: 1. After drilling the drill bit into the structure, the center drilling tool needs to be replaced in time. The bottom of the hole needs to be clean
