Today in our country, construction is developing at unprecedented pace, so the quality pile foundation are in great demand. One of the most important operations in the performance of pile foundation is boring wells under the pile. Currently Bored wells are often used. They are executed in the soil, if necessary, they lowered the special tubes that retain their shape well in the case of the collapse of the walls. To harden designs can be made horizontal directional drilling, which connects the vertical wells.
The choice of the principle of a well depends on the particular situation. To strengthen the walls of the wells recoverable using special tubes or Unrecoverable. Also, the walls of wells can be strengthened with a special solution. The construction of all types of pile foundations laid down in relevant regulations and should be carried out in strict accordance with the standard procedure: 1. Lay ground under the foundation, 2.
The development of pits and their delivery and reception, compulsory fencing of pits 3. Installing the core axis of piles 4. Test piling 5. Full immersion or basic stage of production piles, 6. Removal of heads of piles; 7. Alignment of excavation in locations where the plates are arranged in 8. Pouring concrete space under the plate 9. Installation of plate 10. Acceptance and delivery finished pile foundation.
Ventilated facades: Key Elements of Designs For additional warming of outdoor structures between the wall and cladding can be installed insulating layer – in this case, in this case ventilation gap is left between the lining and insulation. In the ventilated facade design individual layers are as follows: wall insulation, air gap, the protective screen. Such a scheme is optimal, because layers of different materials are arranged with decreasing indices of their heat, and resistance to water vapor permeability increases from outside to inside. 1. Bearing wall A wall is a fulcrum for system. At the device mounted facade, are essential parameters such as: deviations from the walls vertically and horizontally, "littered" corners that are detected by the method of surveying.
Also of considerable importance is the material of which it is built and its degree of wear (if you have any). 2. substructure construction consists of brackets that attach directly to the wall, and bearing profiles forming the skeletal system, with special fastener elements mounted plate (sheet) tiles. The main purpose of designs is to securely attach a plate coating and insulation to the wall so that the insulation between the panel was finishing the ventilation gap. This excludes adhesives and other "wet" processes, and all connections are made mechanically. 3. Heat and sound insulation layer itself insulating layer protects the wall by alternating freezing and thawing, thus equalizes the temperature fluctuations in the wall and prevents deformation, especially adversely affecting the high-rise buildings. Thermal insulation has other advantages – increases the heat storage capacity of the wall and increases the sound insulation in a wide range of frequencies more than twice.
