Why Do You Think This Building Didn't Collapsed Since D Soil As Been Washed Away by toxxnoni(m): 8:41am On Jul 25, 2017 |
My dear nairalander why do you think this building didn't collapsed since the soil has been washed away? This is an eye opener. Let me share a little story In the world of infrastructure (buildings, roads, bridges, etc) there is something called Geotechnincal investigation (Soil test), this soil test has a son called Pile foundation born in an unstable soil. Funny enough this soil test is the cheapest when it comes to constructions of buildings, roads, bridges etc but yet the most ignore.(which is bad, and it is the no.1 failure of your structure). Before any structure is been lied on the surface of the earth this test needs to be done because it give birth to any information that needs to be known about the soil of your site and these help in make proper plan or decision on what to do in order to avoid future failure of the project due to the soil materials. Kindly indicate your interest and I will continue, I still have a lot to discuss here, feel free to ask me questions, I will be uploading lots of pictures too so you can understand better. Thanks 1 Like

Step by step instructions for a successful soil investigation 1) Site reconnaissance It means the inspection of the site and study of topography to get a proper information about the soil and ground water condition. 2)

Planning of soil exploration It depends upon i. Nature of sub-soil ii. Type of structure iii. Importance of structure METHODS OF SOIL EXPLORATION 1. Open excavation 2. Borings 3. Sub surface soundings 4. Geographical methods |

1. OPEN EXCAVATION A pit, eventually, can be excavated for exploring shallower depths, say of the order of 2 to 5 m, or so. Such a pit can be easily excavated at the proposed construction site, if the soil has a bit of cohesion, and the soil samples can be lifted from such different depths, besides making the easy visualization and examination of the different strata. Even undisturbed soil samples can be lifted from such a pit by a process called chunk sampling. |

2. BORING: Soil samples can be lifted from deeper depths by drilling bore holes by using mechanical devices called samplers. The process consists of i. Drilling a hole and visually examining the cuttings coming out from different depths ii. Lifting the soil samples from different depths by using mechanical devices called samplers. Methods of boring i. Auger boring: This is simplest method of boring a whole by hand drilling. These can be used for shallower depths generally confined to depths of about 5 m or so. In cohesive and other soft soils above water table, augers may be used. ii. Auger and Shell boring: Augers are suitable for soft or stiff clays and very stiff and hard clays and sand pumps for sandy soils. Cylindrical augers and shells are used for making deep boring. Hand operated, mechanized ring are used for depths 25m, 50m respectively. iii. Wash boring: this is a simple and fastest method, used for making holes in all types of soils except boulders and rocks. iv. Percussion boring: This method is used to make hole in all types of soils including boulders and rocks. v. Rotary boring (Mud rotary drilling): This method is used to advance hole in rocks and soils. Rotating core barrels which are provided with commercial diamond bits or a steel bit with slots are used for rotary drilling. This method is used to obtain the rock cores, so this method is called as core boring or core drilling.

Soil samples and sampling i. Disturbed sample: in disturbed sampling, the natural structures of soils gets partly or fully modified or destroyed, although with suitable precaution the natural water content may be preserved. Disturbed sample can be obtained by direct excavations by auger and thick wall samplers. ii. Undisturbed sample: in undisturbed sample, the natural structure and properties remain preserved. These samples are used to tests for shear, consolidation and permeability. iii. Non-representative sample: it consists of a mixture of soil from different soil strata. Size of the soil grains as well as the mineral constituents, might thus, have changed in such samples. Soil samples obtained from auger cuttings and settlings in sum well of wash borings, can be classified in this category. Such samples may help in determining the depths at which major changes may be occurring in sub surface soil strata. |

I don't think individuals should be doing soil test. Since it doesn't change much plots by plots. Government should do a geographical soil sampling...,which I think they do. All they need to do is to make the data and info available to every developers. 1 Like |

CaptainFM1: Assuming government takes care of the soil test, I am sure the high level of collapsing here nd dere will be minimal |
