Abstract
The invention discloses a monitoring method of breakwater foundation settlement. The monitoring method of breakwater foundation settlement comprises the following steps: 1) before construction of a breakwater, arranging a steel wire hose through which a traction steel wire penetrates on a breakwater foundation; driving two fixing steel piles at the toes of the two sides of the breakwater, respectively fixing pipe heads at the two ends of the steel wire hose at the tops of the two fixing steel piles, keeping the pipe heads to be higher than a water surface and filling water into the steel wire hose; 2) measuring the water level value of the water in the steel wire hose; 3) threading an automatic traction water level acquisition instrument for the traction steel wire through the steel wire hose and acquiring the water level value of the water in the steel wire hose; 4) subtracting the value obtained in the step 3 from the value obtained in the step 2 to obtain a first elevation value; 5) after a period of time, repeating the step 2 to the step 4 to obtain a second elevation value; 6) subtracting the second elevation value from the first elevation value to obtain a settlement value; 7) repeating the step 2 to the step 6 for multiple times to obtain continuous settlement. The monitoring method of breakwater foundation settlement has the advantages that the monitoring method is simple and convenient, the interference to construction is small and the protection is facilitated.
Description
Technical field
The present invention relates to a kind of monitoring method of foundation settlement, particularly a kind of monitoring method of mole foundation settlement.
Background technology
In deep water mole or submerged breakwater build, need to carry out settlement monitoring, to ensure construction safety.Deep water settlement of soft foundation monitoring at present mainly contains two kinds of modes, and a kind of for laying sedimentation plate, one is electric measuring type method.Adopt the instruments such as differential settlement gauge.Because sedimentation plate must be laid along levee body axis, very large to construction interference, construction ship collision and jackstone construction often can be encountered sedimentation plate, and sedimentation plate is often destroyed, and protects very difficult.Electrical measuring method is after axis place lays, cable can be guided to levee body toe place observes, have advantages of and disturb little to construction, but this method price is higher, complicated operation, needs diver's cooperating, and cable need be guided to toe place from mole axis, when jackstone construction, very easily cable is smashed, promoted the use of on a large scale.Instrument can cause data acquisition discontinuous after destroying, and affects the accuracy of monitored data, and then delays programming, causes serious consequence.Therefore it is a kind of simple, convenient to need to find, and construction is disturbed little, and is easy to the monitoring method of the mole foundation settlement of protection, to solve the practical problem in engineering.
Summary of the invention
The present invention provides a kind of monitoring method of mole foundation settlement for solving the technical problem existing in known technology, the method is simple, convenient, little to construction interference, and is easy to protection.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is: a kind of monitoring method of mole foundation settlement, comprises the following steps:
One) before levee construction, first in wired hose, wear a traction steel wire, then wired hose is laid on mole ground; Two ends tube head 10-20m place outside the toe of mole both sides of corresponding wired hose sets two fixing piling bars, the two ends tube head of wired hose is drawn to the water surface, be separately fixed at the top of two fixing piling bars, the two ends tube head of wired hose all exceeds at least 1-2m of the water surface, fills water in wired hose;
Two) record the water level value of the water surface in wired hose with level gauge or GPS;
Three) with traction steel wire traction water level automatic collector, make water level automatic collector through whole piece wired hose, water level automatic collector is pressed setpoint frequency and is gathered the water level value in wired hose;
Four) by step 2) water level value that obtains deducts by step 3) water level value that obtains, obtain first group of height value of mole ground;
Five) after a while, repeating step two)～step 4), second group of height value of acquisition mole ground;
Six) deduct second group of height value by first group of height value, obtain the sedimentation value that mole ground during this period of time produces;
Seven) repeating step two repeatedly)～step 6) can obtain the continuous sedimentation amount of mole ground.
In described step 1) in, wired hose is across on mole ground.
Advantage and good effect that the present invention has are: adopt wired hose is laid on mole ground, water will be filled in wired hose, the depth displacement of water in monitoring wired hose, and then obtain the sedimentation value that mole ground produces within the corresponding period, disturb little to construction, and be easy to protection, can solve in the soft base monitoring of deep water, tradition observation instrument is as frequent by breakage in installation in sedimentation plate and settlement gauge etc., protection of instrumentation difficulty, it is large that monitored data gathers difficulty, the problems such as the easy loss of data source, simple to operate, convenient, monitoring effect is good, with low cost, and survivable, monitoring accuracy is higher, can meet the requirement of current levee construction to settlement monitoring.

Detailed description of the invention
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of monitoring method of mole foundation settlement, comprises the following steps:
One) before mole 5 constructions, first in wired hose 1, wear a traction steel wire 3, then wired hose 1 is laid on mole ground 7, and it is protected; Two ends tube head 10-20m place outside mole 5 both sides toes of corresponding wired hose 1 sets two fixing piling bars 4, the two ends tube head of wired hose 1 is drawn to the water surface, be separately fixed at the top of two fixing piling bars 4, the two ends tube head of wired hose 1 all exceeds at least 1-2m of the water surface, in wired hose 1, fills water; In the time carrying out the construction of mole jackstone, wired hose 1 is along with mole ground 7 and sedimentation together with 6 at the bottom of dike.
Two) record the water level value of the wired hose 1 interior water surface with level gauge or GPS;
Three) draw water level automatic collector 2 with traction steel wire 3, make water level automatic collector 2 through whole piece wired hose 1, water level automatic collector 2 is pressed setpoint frequency and is gathered the water level value in wired hose 1;
Four) by step 2) water level value that obtains deducts by step 3) water level value that obtains, obtain first group of height value of mole ground;
Five) after a while, repeating step two)～step 4), second group of height value of acquisition mole ground;
Six) deduct second group of height value by first group of height value, obtain the sedimentation value that mole ground during this period of time produces;
