Technical field
The present invention relates to geotechnical engineering Condition Monitoring Technology field, more specifically relate to instrument in a kind of cotton rope formula hole and demarcate position embedded device, being applicable to positioning and mounting structure state monitor mark in built engineering, providing a set of effective device for installing monitor mark accurately, easily and quickly.
Background technology
For ensureing the safety and reliability of geotechnical engineering, the means that Real-Time Monitoring is a kind of necessity are carried out to its structural behavior.For built engineering, can not its structure of extensive damage, so bury the mode that monitor mark can only adopt small bore usually underground.But because bore diameter is little, installing space is very limited, and if directly bury instrument mark underground, accurately can not locate it, also cannot permanent position, these restrictions are buried underground all to monitor target and are brought larger difficulty.Therefore, seeking one can fast and easy location and installation engineering state monitor target device, is a problem demanding prompt solution.
For this problem, new equipment will solve four problems: (1) will ensure that monitor mark buries the accuracy of orientation and spacing.New equipment is wanted strictly as requested monitor can be demarcated position and is arranged in boring, ensures that the instrument do not caused because of a variety of causes mislabels position.(2) construction of boring backfill can not be affected.After monitor demarcates position, will carry out backfill shutoff to boring, due to narrow space, new equipment will reserve enough spaces for backfill construction, can not affect backfilling operation, ensures plugging effect.(3) ensure that monitoring effect is not subject to the impact of embedding manner and backfilling material.After monitor mark has been buried underground, for obtaining good monitoring effect, new equipment should ensure monitor mark and backfilling material close contact, so that monitor mark accurately can capture the change of engineering state.(4) easy for installation, simple to operate.New equipment will accomplish that fitting operation is simple and convenient, is easy to onsite application, and does not disturb by extraneous factor.
Summary of the invention
The object of this invention is to provide instrument in a kind of cotton rope formula hole and demarcate position embedded device, it is made up of several simple assembly.This apparatus structure is simple, without the need to the processing technology of Special complex; Easy to operate, do not need loaded down with trivial details fitting operation; Accurate positioning, does not limit by extraneous rugged environment.
This device is applicable to location and buries any one monitor mark on market (comprising: the underground monitoring elements such as accelerometer, earth pressure cell, speedometer) underground, be particularly suitable for location and installation monitor mark in small space, and install effective, easy and simple to handle.
In order to achieve the above object, the present invention adopts following technical measures:
In a kind of cotton rope formula hole, position embedded device demarcated by instrument, and it is made up of parts such as installing plate, flexible suspension line, through wires hole, positioning spiro pit, positioning bolt, counterweights.It is characterized in that: monitor mark seccotine is fixing on a mounting board, by flexible suspension line through the through wires hole on installing plate, according to monitor target position, with positioning bolt, installing plate is fixed on flexible suspension line, positioning spiro pit and through wires hole are vertical communicating, positioning bolt mounting plate, coordinate positioning bolt can reach the object of mounting plate, balance weight hanging is bottom flexible suspension line, for ensureing the verticality of package unit, in boring, insert Grouting Pipe, slip casting is until slurries fill boring.
Described installing plate is made up of organic glass, and installing plate diameter can be selected arbitrarily within Φ 40-150mm, installing plate thickness 4-6mm.An installing plate edge preboring 3-5 through wires hole, diameter is at 2-4mm, and through wires hole is apart from installing plate edge 1-3mm.Its side symmetrical preboring 3-5 positioning spiro pit, diameter 1-3mm, positioning spiro pit will be got through with through wires hole.
Described flexible suspension line is the nylon rope that intensity is higher, on market any one, its diameter mates with the through wires hole according to installing plate, and diameter, can not be too thin at 2-4mm.
Described through wires hole diameter 2-4mm, preboring on a mounting board, bores installing plate, and its edge is far from installing plate edge 1-3mm.
Described positioning threads bore dia 2-4mm, preboring on the side of installing plate, the degree of depth is 4-6mm.Positioning spiro pit will communicate with through wires hole is vertical.
Described positioning bolt mates with positioning spiro pit and uses, diameter 2-4mm, length 5-7mm.
Described counterweight is made up of the iron block of weight 250-300g, and shape is hollow cylinder, and diameter is less than installing plate diameter, and select arbitrarily within Φ 40-150mm, length is no more than 100mm.
Described seccotine is specially Henkel hundred and obtains strong all-purpose adhesive.
The present invention is that in a kind of cotton rope formula hole, position embedded device demarcated by instrument, has the following advantages and effect:
The present invention strictly can control monitor target position and distance on request, does not affect backfill pouring construction, is not subject to the restriction of backfilling material and job site, can ensures monitor mark and backfilling material close contact, ensure monitoring effect, in addition, structure of the present invention is simple, easy and simple to handle, be applicable to engineering site to use, there is higher practical value.Specifically have following some:
1) monitor mark is fixing on a mounting board, and installing plate can directly be positioned on flexible suspension line.Accurately and rapidly monitor can be demarcated position is in this way embedded in the narrow spaces such as boring, easy to operate, and it is accurate to install effect, can strict guarantee sensor position in the borehole and spacing;
2) according to size and the degree of depth of bore diameter, the diameter of installing plate and the length of flexible suspension line can adjust arbitrarily, have better compliance, can be backfill construction and reserve enough spaces narrow and small space of burying underground, are easy to backfill;
3) owing to being flexibly connect between the monitor mark on installing plate, can not have an impact each other, ensure that the effect that roadbed is monitored;
4) by positioning bolt, installing plate and monitor mark are fixed on flexible suspension line, can greatly reduce, as the execution conditions such as slip casting to bury the impact of effect underground on monitor mark, monitor target installation quality can be ensured completely;
5) this device is without the need to the installation process of complexity, simple to operate, and execute-in-place is strong, can adapt to different complicated, severe site environment.
For verifying that this device location buries effect underground, use length 5m, diameter is respectively three pvc pipes of 76mm, 108mm and 160mm as simulation boring, has buried 10 layers of monitor mark underground respectively in the position of 0.3m, 0.5m, 0.8m, 1.2m, 1.6m, 2.1m, 2.7m, 3.5m, 4.2m, 4.8m.Demonstration test proves, process of burying underground does not need complex operations, consuming time short, and backfilling operation takes up room little, and only just can backfill simulation boring with thinner force pipe and less pressure, backfill effect is better.After pipe inner concrete solidifies, cut open pipe and find, monitor mark is positioned in simulative tube on request, monitor mark maintains level on request, and position deviation is no more than 2cm, and accuracy reaches 99%, sensor contacts closely with pipe inner concrete, ensure that the transmission of dynamic response parameter in concrete.Through vibration test checking, the dynamic response rule of pipe inner concrete is consistent with achievement in research, and sensor vibration effect better and is not substantially subject to the impact of embedded device.
The present invention is reasonable in design, and structure is simple, largely solves and accurately bury a monitor target difficult problem underground in built engineering, be conducive to realizing fast, efficiently, Embedded installation monitor target object easily.
