Technical field
The present invention relates to a kind of civil works stake guard method, specifically, is the guard method of a kind of excavation slope engineering pile.
Background technology
In the metallurgical equipment basis of continuous overlength, be all densely covered with engineering pile (bearing pile), during equipment Foundations construction, according to the difference of embedded depth of foundation, need layering, block construction.To the deep foundation ditch (more than-5m) putting slope heavy excavation, side slope just there is the engineering pile of a lot of adjacent foundation by out exposed, when the discrepancy in elevation that stake both sides are exposed reaches 1.5m and is above, there is the side pressure of the soil body in pile body side, if domatic side is contiguous carry track road, its lateral pressure is enough to cause stake to produce displacement, inclination, even broken pile equivalent risk, causes jeopardizing personnel and deep pit monitor.
Therefore the engineering pile on known excavation slope also exists above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is to propose a kind of excavation slope engineering pile guard method preventing engineering pile displacement, inclination, broken pile.
For achieving the above object, technical solution of the present invention is:
The guard method of a kind of excavation slope engineering pile, described engineering pile is pile tube, it is characterized in that comprising following technical measures:
A, protect an exposed clump of piles with steel pipe with " intersection flower rack type "
When excavation slope engineering pile is an exposed clump of piles, be interconnected with an exposed clump of piles with " intersection flower rack type " with some steel pipes, steel pipe adopts the supporting fastener of scaffold tube to be connected and fixed, and an exposed clump of piles is connected into rigid unitary, protects an exposed clump of piles to resist soil body lateral pressure;
B, protect the exposed stake of foundation ditch both sides with " double crossed frame type " with steel pipe
When both sides are foundation ditches, when the middle engineering pile of both sides excavation slope is exposed stake, with some steel pipes with " double crossed frame type " the symmetrical drawknot of middle engineering pile with both sides excavation slope, steel pipe adopts the supporting fastener of scaffold tube to be connected and fixed, to resist the exposed stake of soil body lateral pressure protection foundation ditch both sides;
C, protect single exposed stake with steel pipe with " double crossed frame type "
When excavation slope engineering pile is exposed single pile; by the stake of foundation ditch external works; with some steel pipes with " double crossed frame type " with the engineering pile in side slope and foundation ditch external works stake drawknot, steel pipe adopts scaffold tube supporting fastener to be connected and fixed, to resist the single exposed stake of soil body lateral pressure protection.
Excavation slope engineering pile of the present invention guard method can also be further achieved by the following technical measures.
Aforesaid method, wherein said steel pipe is the steel pipe of scaffolding, and it is of a size of 48 × 3.5mm.
After adopting technique scheme, excavation slope engineering pile of the present invention guard method has the following advantages:
1, the destructions such as the engineering pile on excavation slope is not subjected to displacement, inclination broken pile are guaranteed;
2, foundation ditch and personal security is ensured.
