Description
Technical field
The present invention relates to a kind of field of measuring technique, the subsidiary of specifically a kind of sewage open caisson internal structure fills
It sets and measurement method.
Background technology
Caisson method is one of important construction method used by building underground engineering and buried foundation engineering, is being constructed
When place level of ground water is higher, water yield is larger or has the geological conditions such as underground bearing water, quicksand, weak soil, using open caisson construction
It is most appropriate.In coastal weak soil city sewage treatment works, the active well of sewage network mostly uses Construction Scheme of Open Caisson,
Sewage open caisson composition generally comprises pit shaft, top plate and bottom plate, inner wall, nozzle, cutting shoe etc., and flat shape is mainly round and rectangle.
On road surface it can be seen that sewage open caisson pit shaft internal diameter normally only 0.7m, and the open caisson size below road surface is often very big, round
The diameter of sewage open caisson is generally in 5m or more, and the size of rectangle sewage open caisson is generally in 3m × 5m or more.When sewage open caisson data
It when complete filing, can be really sized by consulting completion information, the information such as buried depth, however in real work, it is frequently present of receipts
The case where collection is less than completion information, in this case, it is necessary to which live positioning is carried out to the sewage open caisson of certain specific positions
It measures.
At present in engineering there are mainly two types of the measurement methods of underwater sewage open caisson:
1, using geophysical prospecting method(Such as reflective wave method, geological radar method)Carry out in-situ measurement.But in the coastal of phreatic high
In weak soil city, Effect on Detecting is not often understood.
2, it carries out underground using frogman to feel, be measured by simple straight-bar and lining rope, due to sewage open caisson only top
Pit shaft exposure, open caisson inner wall generally within oilysewage surface hereinafter, underground location is difficult, the amateur survey crew of frogman in addition, to
So that the measurement accuracy of sewage open caisson internal structure is low.
Now, China is just locating the urban track traffic large-scaled construction period, and rail line passes through inner city mostly,
It is laid below major urban arterial highway, underground station is generally positioned at two major trunk roads intersections, and urban road both sides are often distributed
There is intensive sewage network facility.Active well of the sewage open caisson as sewage network changes and moves more difficulty, and change and move the required duration
It is long.At home the rail line completion time of project it is generally more nervous in the case of, underground station horizontal layout is taken substantially keeps away
The internal structure opened the measure of large scale sewage open caisson, therefore accurately ascertain the sewage open caisson of certain specific positions seems particularly heavy
It wants, this may directly influence the feasibility of underground station design scheme.
Invention content
It is an object of the invention in view of the above-mentioned defects in the prior art and insufficient, provided in a kind of sewage open caisson for people

The length of the upper guide rod and lower guide rod is 0.5 meter.
The single-unit length of the main rod body is 2.5 meters.
The length of the bottom supporting rod is 1 meter.
A kind of measurement method of sewage open caisson internal structure, it is characterised in that include the following steps:
Step 1:Using the depth of plumb line preliminary surveying open caisson to be measured, the master of aided measurement device is chosen according to preliminary survey depth
The joint number of the body of rod, is used in combination fixing nut to connect, and measurement rope is connected in the lower fixing end of lower guide rod, then by subsidiary
Device is vertically arranged in open caisson, bottom supporting rod to shaft bottom.
Step 2:Frogman goes into the well, and tentatively feels shaft wall structure, determines that caisson structure is round or rectangle.
Step 3:Frogman tenses in shaft bottom and measures rope to the borehole wall, and lower guide rod can rotate the direction one with measurement rope automatically
It causes, reads the scale for measuring rope, inform that ground staff, ground staff catch on guide rod using tape measure by wired intercom system
Upper fixing end, pinpointed according to the length that direction shown in upper guide rod and frogman measure, and marked on ground.
Step 4:Repeat step 3, for circular open caisson, measure measuring point and be no less than 4, measuring point should be evenly distributed as much as possible in
Entire circular open caisson;For rectangular open caisson, 3 rectangle angle points are measured.
Step 5:Frogman tenses in shaft bottom and measures rope to nozzle, and lower guide rod can rotate the direction one with measurement rope automatically
It causes, reads the scale for measuring rope, ground staff is informed by wired intercom system, ground staff is according to direction shown in upper guide rod
Determine nozzle direction.
Step 6:The coordinate that land mark point is measured using total powerstation or GPS, for circular open caisson, using 3 measuring points
Coordinate can be fitted to obtain a circle, be checked using remaining measuring point, the inner wall of gained circle, that is, open caisson to be measured;For square
Shape open caisson can obtain a rectangle, the inner wall of gained rectangle, that is, sewage to be measured open caisson according to 3 angular coordinates;Along with heavy
The well borehole wall estimates thickness, you can obtains the plane overall size of sewage open caisson.
Step 7:Open caisson bottom plate buried depth can be directly measured using main rod body, in conjunction with the elevation at the inspection well cover of open caisson ground, i.e.,
It can convert to obtain the elevation at open caisson bottom plate.
It is 0.4 meter to 0.6 meter that the caisson wall, which estimates thickness,.
