Abstract
The invention discloses a construction technology capable of inserting a pile through a gravel bed via a lead hole, and belongs to constructional engineering. An upper soil layer, a gravel bed, a lower soil layer and a lead hole are arranged. The technology is characterized in that the lead hole is vertical, the lower end of the lead hole is ended in the joining part of the gravel bed and the lower soil layer, and the lead hole is a cavity blind hole with the diameter slightly less than the diameter of a pile. Compared with the prior art, the construction technology capable of inserting the pile through the gravel bed via the lead hole breaks through a bottleneck that a pile-sinking technology cannot be applied to construct foundations because the soil layer density is uneven and the pile cannot penetrate through the dense gravel bed under complicated geological conditions, therefore, the technology has good popularization and use values.
Description
One, technical field:
The present invention relates to construction work, relate to specifically a kind of hole pile sinking that draws and pass through the sandy gravel stratum construction technology.
Two, background technology:
The static pressure pile-sinking technology is few because of its pile pipe reliable in quality, the construction amount of breaking ground, stake position, direction, accurately easily control of the degree of depth, on-the-spot clean and tidy, press the cultivation noiselessness, progress of implementation is fast, the duration is short, cost is low etc., and numerous advantages are favored by industry extensively, be widely used, but often because of the region complex geologic conditions of constructing, soil density inequality, layer compression is larger than difference, can not penetrate compacted zone (as the sandy gravel stratum that hardens) to pile pipe, construct pile foundation and use other method instead.
Three, summary of the invention:
The objective of the invention is for above problem, provide a kind of pile pipe to pass through smoothly compacted zone, the hole pile sinking that draws that reaches the engine request degree of depth and bearing strength passes through the sandy gravel stratum construction technology.
The objective of the invention is to be achieved through the following technical solutions:
A kind of hole pile sinking that draws passes through the sandy gravel stratum construction technology, comprises topsoil, sandy gravel stratum, subsoil and draws the hole, it is characterized in that drawing the hole and be vertical, draw the lower end, hole end at sandy gravel stratum and subsoil joint portion, diameter is slightly less than the empty blind hole of pile pipe diameter.
The hole pile sinking that draws of the present invention passes through the sandy gravel stratum construction technology, be difficult to penetrate the low compression ratio compacted zones such as sandy gravel stratum for static pressure pile-sinking, do not reach the engine request degree of depth, helplessly use the situation that other constructs pile foundation instead, penetrate the hole technology of drawing of compacted zone with drill hole of drilling machine, realize pile pipe smoothly by compacted zone, break and hinder the application bottleneck of using static pressure pile-sinking, open the range of application that expands the static pressure pile-sinking technology, thereby have good value for applications.
Four, description of drawings:
Fig. 1 be draw that the hole pile sinking passes through the sandy gravel stratum construction technology draw hole side generalized section.
In figure: 1 topsoil, 2 sandy gravel stratums, 3 subsoils, 4 draw the hole.
Five, the specific embodiment:
As shown in Figure 1, the degree of depth, the thickness of the sandy gravel stratum 2 that the Accurate Determining pile pipe is difficult to pass through, unwrapping wire location, rigging up, its drilling rod gradient must not be greater than 0.5%, drill hole, bore topsoil 1 and return to bore to sandy gravel stratum 2 and subsoil 3 joint portions and withdraw from, clearly now draw the interior mud in hole 4 and the surface is on-the-spot, cover to seal pile sinking to be pressed.
Except the described technical characterictic of manual, be the known technology of those skilled in the art.
Claims (1)
1. one kind is drawn the hole pile sinking and passes through the sandy gravel stratum construction technology, comprises topsoil, sandy gravel stratum, subsoil and draws the hole, it is characterized in that drawing the hole and be vertical, draw the lower end, hole end at sandy gravel stratum and subsoil joint portion, diameter is slightly less than the empty blind hole of pile pipe diameter.
