Abstract
The invention relates to a monitoring method for the perpendicularity of a steel pipe pile in the field of foundation pit bracing engineering monitoring. The monitoring method comprises the following steps that (a) a protecting steel pipe (1) is connected with a steel pipe pile (2); (b) the protecting steel pipe (1) and the steel pipe pile (2) are sunk into a soil body together, and a fixing inclinometer pipe (3) is installed in the protecting steel pipe (1); (c) an inclinometer (4) is stored into the inclinometer pipe (3); (b) the perpendicularity or the perpendicularity change of each section of the steel pipe pile (2) is monitored by measuring the inclinometer pipe (3) in the piling or foundation pit excavating process; and (e) the perpendicularity after piling is completed or the deep horizontal displacement in the foundation pit excavating process of the steel pipe pile (2) is calculated. According to the monitoring method for the perpendicularity of the steel pipe pile, the implementation speed is quick, data are reliable, manufacturing cost is low, and quality is good.
Description
Technical field
The present invention relates to the Foundation Pit Support Engineering monitoring field in Geotechnical Engineering field.
Background technology
Steel-pipe pile and steel-pipe pile diaphragm wall as the full foundation pit enclosure structure for reclaiming realize all kinds of depth in weak soil or
The full recovery of the foundation pit enclosure soil-baffling structure under all kinds of geological conditions such as pan soil, after the completion of piling and steel-pipe pile in use
Perpendicularity and its monitoring of changing value be directly connected to engineering safety, be steel-pipe pile and steel-pipe pile diaphragm wall in foundation pit enclosure work
Important step in journey field.
The content of the invention
The purpose of this reality invention is to provide a kind of steel pipe pile verticality monitoring method, and the steel pipe pile verticality monitoring method can
Lateral displacement measurement of the steel-pipe pile in the soil body, monitoring cost during for the degree control and excavation of foundation pit during piling
Low, degree of safety is high, reliable in quality.
The steel pipe pile verticality monitoring method is comprised the following steps：
A) protection steel pipe is connected with steel-pipe pile；
B) protection steel pipe is sunk to into the soil body together with steel-pipe pile, and fixed inclinometer pipe is installed in protection steel pipe；
C) inclinometer is inserted into inclinometer pipe；
D) each sectional vertical degree of the steel-pipe pile in piling or Excavation Process or vertical is monitored by measuring inclinometer pipe
Degree change；
E) calculate deeply mixing cement-soil pile of the steel-pipe pile in the perpendicularity after the completion of piling or in Excavation Process.
The steel pipe pile verticality monitoring method of the present invention, it can be ensured that monitoring instrument is not broken in pile driving process with equipment
It is bad, can calculate the perpendicularity of each section of steel-pipe pile, and the change calculations steel-pipe pile case of bending of each section of perpendicularity of steel-pipe pile can be passed through,
Data acquisition reliability is high, low cost.
Description of the drawings
Fig. 1 is that the steel-pipe pile cross-sectional configuration with perpendicularity monitoring device used by one embodiment of the present of invention is illustrated
Figure.
Specific embodiment
As present invention one embodiment as shown in Figure 1, the main steel pipe pile verticality monitoring method for introducing the present invention
Implementation steps.At first of the present embodiment, protection steel pipe (1) is firmly connected with steel-pipe pile (2), welding manner can be taken
Connection, i.e., be directly welded on protection steel pipe (1) on the side wall of steel-pipe pile (2).In this step, protect steel pipe (1) Ying Yugang
The parallel laying of pile tube (2), it is vertical with steel-pipe pile (2) corresponding segment with the perpendicularity for guaranteeing each segmentation for protecting steel pipe (1)
Degree be it is consistent, and should cause protect steel pipe (1) internal diameter more than inclinometer pipe (3) outline, in order to inclinometer pipe (3) place
In protection steel pipe (1).Protection steel pipe (1) can be laid in the outside of steel-pipe pile (2), it is also possible to be laid in steel-pipe pile (2)
Inner side.So as to complete the first step of the present embodiment, into second step.In this step, will protection steel pipe (1) and steel-pipe pile (2)
The soil body is sunk to together, and the mode of sinking to can be completed using the one or more combination in vibratory drilling method, static pressure method or hammering method.Because of protection
Steel pipe (1) is firmly connected with steel-pipe pile (2), therefore steel-pipe pile (2) synchronous with protection steel pipe (1) can become during the soil body is sunk to
Shape or inclination.Can install solid in protection steel pipe (1) before steel-pipe pile (2) sink to the soil body or after steel-pipe pile (2) sinks to the soil body
Location survey inclined tube (3), the one or more combination in can adopting with the following method between inclinometer pipe (3) and protection steel pipe (1) are fixed, the
A kind of fixing meanss be by inclinometer pipe (3) be positioned in protection steel pipe (1), then, inclinometer pipe (3) and protection steel pipe (1) it
Between inject cement mortar, after cement slurry sets, inclinometer pipe (3) will be fixed in protection steel pipe (1)；Second fixing means can
To be such, after steel-pipe pile (2) sinks to the soil body with protection steel pipe (1), inclinometer pipe (3) is inserted in protection steel pipe (1), then
The charges of sand or other forms are inserted in space between protection steel pipe (1) and inclinometer pipe (3), so as to by inclinometer pipe (3)
It is fixed with protection steel pipe (1).The second step of the present embodiment is completed, into the 3rd step.In this step, only need to be by inclinometer (4)
Inclinometer pipe (3) is inserted, can start to determine the perpendicularity that inclinometer pipe (3) is respectively segmented.The 3rd step of the present embodiment is completed, into the 4th
Step.In this step, by measuring the perpendicularity of each segmentation of inclinometer pipe (3), steel-pipe pile (2) can be calculated during piling
Perpendicularity, it is also possible to the perpendicularity of each segmentation of steel-pipe pile (2) is monitored by the different time in Excavation Process, calculates steel
The perpendicularity change that pile tube (2) is respectively segmented, so as to the deeply mixing cement-soil pile of steel-pipe pile (2) can be calculated.In the present embodiment, steel pipe
Stake (2) can be the steel-pipe pile diaphragm wall for being connected with connector between stake (5).Complete the steel pipe pile verticality monitoring side of the present invention
Method.
This patent includes but is not limited to alternative other construction methods for using of professional person in the art.
