The procedure works on repair of the foundation with the help of screw piles with their hands

The most expensive item in the budget building - improvement of the foundation.The same fully applies to the question of repairing it, which is understandable - "resuscitating" the bottom of any structure is very time-consuming process, even if only partially engaged in dismantling buildings.The optimal solution to this problem - the reconstruction of the basement using screw piles.

In fact, the meaning of the "surgical intervention" - the installation of additional supports in the right places, which prevent the further destruction of the base and prolong the operating life of the structure.In the most severe cases - installation of a new base in parallel with the old one.There are several techniques, but not all of them can be implemented independently.Two main reasons.

First , to properly chart the placement of piles, you need to understand the issues of building on a professional level, and making calculations to take into account many factors (load, soil characteristics, specific installation and a number of others).

Second , in most cases, require special equipment, which, of course, have no owner when significant damage base.

But it was reconstructed with the use of piles is the least expensive way to repair the foundation.To the advisability of such work has become more clear, it is necessary to provide some data.Clarify once again - the term "reconstruction" means or additional reinforcement of the foundation with the condition that the old remains in place, or complete its replacement on the basis of the type of the pile with the dismantling of the original (eg, tape blocks).

Consider the most simple method, which allows almost all operations to perform on their own, as the subtleties of working professionals in the reader is unlikely to be of interest, except for its finalcost and indicative data is already marked.

Procedure

Since the most common type of buildings base in the private sector is the "Ribbon", all further description will be oriented to repair it this foundation.If you understand the meaning of all the operations, it is easy to determine the sequence of actions for its other varieties.

Development

work plan That is, not just banal charting.Draw on a sheet of paper outlines the structure of each can.But in addition it is necessary to take into account such factors:

• Parcel (soil characteristics, topography, occurrence of underground water reservoirs).
• climate Specificity (the level of soil freezing, the intensity of precipitation, extreme temperatures).
• general plan area (adjacent building), as well as the perspective of a building in the immediate vicinity of the house.

What is it?To determine the optimum cross-section piles in terms of installation and the required penetration (and hence the length of the product).

Preparations

Their volume depends on the structure of the specifics, so we list everything that should be done regardless of the nuances of future work:

• disconnect supplied to the home communications.If necessary, the partial dismantling of the individual sections of the route.Cables, pipes should not interfere in the future;
• make all the excess out of the buildings, especially large and heavy items (equipment).This must be done in advance, as in the process of excavation can not be ruled out spontaneous distortion and sagging home, because its center of gravity is unlikely there will be displaced.

Trenching

task - not only gain access to the base, but also to equip the place for further work.For ease of manufacturing operations optimal width - within a meter.But the depth should be slightly more than this parameter tape.

Installation of a new design

• On the perimeter, in accordance with the scheme drawn up, installing the supports by screwing.For this operation will need a minimum of 2 persons - 1 to control and alignment, the second - for screwing piles.

• property rises.This will require strong jacks, calculated on a lot of weight (called "hydraulic construction").If you buy, then the approximate cost of a product - from 1020 rubles (for "dvuhtonnik").equipment rental will cost approximately 500 - 550 rubles / day.If we consider that all the work can be done in 2 - 3 days, these figures are quite comparable.

• on pile heads fixed metal beams.It turns out a square or rectangle with the sides a little larger than that of the base.To the construction is not "failed", additionally welded cross members.

• After preparing such a "lattice" structure is omitted.To prevent horizontal displacement of the lower bound is made crown (base frame) with a metal structure.

These are the main stages of work, but for a better understanding of the methodology should be noted some of the nuances:

• piles need not be screwed for the whole of their length."Grinder" extra easy to cut at the optimal burial.
• If support is needed to further strengthen, the concrete is poured into the solution (with filler fines, for example, pebbles).
• case of partial destruction of the base structure can not raise.To this end, the foundation set on opposite sides of the pile in the tape cut a "window" in which infest and channels.They are mounted on the end walls and towers are part of the old structure.It is especially necessary for accurate calculation of the height of installation.Can simply "prop" the tape on one side.

drawings illustrate well all moments, and understand the meaning of the work on them is not difficult.And what is more suitable, it is solved on the spot.

fairness it should be noted that such variants of reconstruction of the foundation are only suitable for relatively light structures - houses made of wood, prefabricated panel, frame, ie thoseEasy to at least one side lift (except for the last partial damage).

For those readers who are interested in other techniques, we give them a small list, and information on "how to ... with their hands" on our website to find a snap.

• Cementation.
• Installation w / w "shirt" (or "cage").
• installation of so-called handling elements (beams, frames, braces, struts and the like).
• Strengthening reinforcement bars.

is worth noting that such methods do not solve the problem completely, and allow only delay the start time of overhaul of the foundation.In terms of complexity, effort, financial investments, practicality still foregoing method using piles most preferred.
