Loosening the soil of the base

  • November 29, 2024

Loosening the soil of the base due to the removal of its smallest particles with fluid or groundwater or with intense drainage. The removal of the smallest particles of the soil, which is especially intensively with a significant drainage of both directly from the pit and with the help of tubular wells with filters of insufficient frequency, weakens the bearing capacity of the base. If the ground is taken for a long period of time, then damage to other structures located nearby are possible.

At the end of the construction of a stone four -story building, erected near the gateway canal, cracks were found in the middle part of the building from the front facade and a number of hair cracks from the inside of the building. Even before starting construction work, with a pink and drilling, it was found that a powerful layer of bulk soil with a fall of sandy aquifers located under it lies to a depth of 5 – 6.5 m towards a depth of 5 – 6.5 m. According to the stories of the old -timers, at the site of the built -up site, there was a backwater, then turned into a pond, subsequently falling asleep. Given this, the foundation under the body made of a boot on a concrete pillow was laid at a depth of 4.5 – 5 m on the basis of river sand in places with an admixture of cartilage, allowing pressure and soil at 2.4. The first OIL case is almost completed when they began to Rytyo pits for the second building. The soil at the base of the latter was partially the same nature as under the first case, partially consisted of small sand with an admixture of silt, saturated with water, which passed into larger sand with an admixture of cartilage.

The foundation for the second case was laid at a depth of B – 6.5 m in the form of lamp pillars on a concrete pillow. Since groundwater stood above the design mark of the sole of the foundation of 1.5 m, the ducking of the pit was made with a drainage. In addition, for the sewage device, ditches were dug along both buildings. As a result of the described method of work, both in the first building and in two neighboring houses, cracks were discovered, the formation of which was caused by the following reasons:

1. The layout of the soil indicates the existence of an underground flow going towards the channel according to the old -river, which existed before backfilling, which contributed to the movement of soil particles at the base of the first building.

2. Digging a foundation pit for the second building, produced with drainage at a time when the first building was already erected almost to the full height, caused the flow of the smallest particles of the soil from the foundation of the first building and contributed to a further violation of equilibrium at its basis.

3. Leaching of soil particles from the base intensified even more when it was started to dig ditches for sewage, as they acted like drainage that sucks water from the base along with the smallest particles of soil.

4. The fact that during digging the pit under the foundation of the first case, the water in the channel was lowered, and at the beginning of the summer again, it contributed to the saturation of soil water at the base and a decrease in its bearing capacity.

  • This object has such a fate that involuntarily allocates it among others in Kazakhstan. The bridge across the Ural River in the administrative center of the West Kazakhstan region began to be built in the “good old days”, that is, under the Soviet regime. Since the republic never had their own organizations specialized in this case, bridge builders from different Russian cities worked here here. Then there was a notorious “parade of sovereignty”, followed by an economic crisis. Although the construction of the bridge continued, however, the payment of the executed volumes was now constantly delayed, or even at all moved away for an indefinite period. For this reason, the bridge builders stopped working several times. However, the object in Uralsk is one of the most significant in Kazakhstan, and therefore did not forget about it: the press periodically woke up this topic. Increased attention is also explained by the fact that the bridge across the Urals does not just connect the two banks of the river, it makes up an important link on the shortest path from Central Asia to the European part of Russia. As a result, the story of the invitation of bridge builders from a neighboring state was repeated again and again, without a visible result. There is a rather funny moment in it. A couple of years ago, when the President of Kazakhstan Nursultan Nazarbayev arrived in Uralsk, the local authorities invited him to take part in the solemn open… bridge over the Urals. The head of state made sensory words and cut the red ribbon. But when the ceremony ended and the president left, the entrance to the bridge was closed. The fact is that every driver who would decide to update the shortest path from Central Asia to Russia could well have been on the other side, but at the bottom of the river. The object was not over. And the main difficulty was not so much in building a car transition through the Urals itself, but in the construction of multi -kilometer approaches to it through a constantly flooded floodplain. And work here still start and finish. And now in the republic they decided to return to the long -suffering object again. The Ministry of Transport and Communications of the Republic of Kazakhstan announced the competition for state procurement of works and services for the reconstruction of the bridge over the Ural River. The required delivery time within 2000. Potential suppliers who meet the qualification requirements stipulated in Article 10 of the Law of Kazakhstan “On public procurement” are allowed to the competition.
