Water Well Drilling: Drilling Methods to Consider

A water well is an excellent source of water in your home. When planning to drill your well, you will want to consider things such as the competence and reliability of the drilling company, the cost of drilling the well, and the amount of space required. Another important thing to consider before your well is drilled is the drilling method to use. There are various water well drilling methods, each with its own merits and demerits. Here are some drilling methods you may want to consider for your well.

Rotary Drilling With Flush

With this type of drilling, a drill bit is rotated through a drill pipe to cut through the rock. Drilling mud is then pumped down the pipe to flush out dust, cuttings, and any other debris. Rotary drilling can drill through a wide range of rock formations, making it a more versatile option. In addition, it uses drilling mud (to flush out the dust and other debris), which can support unstable rock or soil formations. Rotary drilling with flush can also operate both below and above the water table and can drill deeper depths, which prevents contamination since shallow wells are more likely to be susceptible to contamination. The drawback of this drilling method is that you will need a good amount of water since it’s used for pumping.

Rotary-Percussion Drilling

This method uses pneumatic hammers to pulverise hard rocks. The hammer is driven by compressed air, which flushes out materials from the borehole as the hammer drills through. The first advantage of this drilling method is that it is ideal for drilling hard rocks such as granite. Therefore, if your ground has been found to contain granite, you may want to go for this option. It can also penetrate gravel, and it’s a fast method that will work well both below and above the water table. However, you will need an air compressor, which can increase your drilling costs. Besides, this method may cost you much more compared to other methods.

Jetting

This form of drilling uses water as the main component for washing, aiding cutting, and flushing out the debris. The debris then emerges as a jet. Internal combustible pumps can also be used to facilitate the washing and cutting. Jetting is relatively inexpensive compared to the other two methods and can work well below and above the water table. However, further drilling can be hindered by boulders. In addition, it’s only ideal for unconsolidated rock formations, such as silt, clay, and sand.

Understanding the Steel Detailing Processes for Your Building’s Design

Have you ever heard about construction projects collapsing and causing major injuries and death? Well, poor structural detailing is often the cause of such tragic occurrences. There are more aspects to a building than what you just want it to look like. Strength is among them, and it is achieved by supporting the building with a strong structure of steel. The layout of the structure should be done by a structural steel professional to guarantee adequate strength to the building. This will ensure the safety of the workers on the site, together with the people passing or living in the nearby areas. In addition, you will avoid unnecessary expenses resulting from the reconstruction of the collapsed sections. Here is what you should know about the steel detailing procedure for your building design:

The Erection Drawings

The erection drawings are the first part of the steel detailing procedure on your commercial building. They are the dimensional plans of your building showing the specific geographic location of each of the structural component. The drawings also include the requirements for installation and other works associated with the steel component of the building. This will act as a guideline for your workers to ensure that the structural support they use can sustain the weight of the building at each specific point.

The Shop Drawings

After the engineer has generated the erection drawings of the buildings, they also come with the shop drawings. The shop drawings are important because they tell you what you need to buy and how it should be made. They have details on the braces, columns, beams, and joints and the type of materials that you should use to reinforce each section. The material will vary depending on the size and type of building. For instance, storey buildings have thicker beams, which means that you will use denser structural steel to support the beams, unlike those you would use for a bungalow.

Most importantly, the shop drawings tell you how the steel components should be made by the fabricator. Rather than having to give the whole description, the drawings will tell you the structural steel gauge that you should ask for from the seller. The shop drawings are about the type, modifications requirements, and the number of structural support components you should buy. For instance, you may have to paint some of the components to make them resistant to corrosion. These drawings will specify such details and tell you the paint you should buy. 

National and local authorities are keen on safety during construction. You need these structural drawings for your building’s design especially during government inspections so that they allow you to go on with the project.
