Description
Technical field
The utility model belongs to engineering construction field, and in particular to a kind of open caisson construction testing apparatus for verticality.
Background technology
Open caisson construction is a kind of method of underground Construction of Deep Foundation.Its main feature is that：A well shape knot is first made on the ground
Then structure is constantly cut the earth in well, conduct oneself with dignity by means of well body and gradually sink, and forms a underground structure.Open caisson construction is chiefly used in
The facilities such as jumbo basis, bridge pier, pump works, water intaking structure, super high rise building basis, oil cellar and underground power plant
It builds.
During well sinking, it is the key technology of influence construction quality to prevent inclination of open caisson, and traditional detection open caisson
The tool of verticality is theodolite, when due to being measured using theodolite, often measures an angle and is required for setting up instrument, also want
It is helped by special messenger, and measurement data need to be calculated and can just obtain testing result, not only measurement method very complicated, Er Qie
Night can not measure operation, have larger impact to construction speed；In addition, with the increase of well sinking depth, people is helped
Dangerous increasing, the instrument decorating position also more and more bad selection of member, there are construction safety in terms of hidden danger.
Utility model content
The utility model provides a kind of open caisson construction testing apparatus for verticality, simple in structure, passes through laser transmitter projects
Laser can determine the verticality of open caisson, and is adjusted to inclination of open caisson degree by laser position above laser receiver sheet, right
There is realistic meaning in quickly improving open caisson construction speed.
The technical solution of the utility model is as follows：
A kind of open caisson construction testing apparatus for verticality, including holder, reference plate, plumb line, laser generator and laser
Receiver sheet, on open caisson wall top, surrounding is evenly arranged four holders, and four holders are described with reference to flat with four respectively
Plate welds together, and the line tail of the plumb line is connect with the reference plate, and lead head and the laser of the plumb line are sent out
Raw device connection, in open caisson wall lower part and the holder opposite position four laser receiver sheets of setting, in the laser receiver sheet
Graduated scale is arranged in heart position, in the centrally disposed centring hole of the graduated scale.
The open caisson construction testing apparatus for verticality, preferred embodiment are that the holder is arranged at the top of open caisson
At 100mm, laser receiver sheet setting is apart from the 100mm of open caisson bottom at, and the holder is erected with the laser receiver sheet
To correspondence.
The open caisson construction testing apparatus for verticality, preferred embodiment are that the graduated scale precision is 1mm, described right
Mesopore pore size maximum value is corresponding with code requirement inclination of open caisson degree maximum value.
The beneficial effects of the utility model are：The utility model is simple in structure, can by laser transmitter projects laser
It determines the verticality of open caisson, and inclination of open caisson degree is adjusted by laser position above laser receiver sheet, for quickly carrying
High open caisson construction speed has realistic meaning.
Description of the drawings
Fig. 1 is open caisson construction testing apparatus for verticality structural schematic diagram；
Fig. 2 is reference plate, plumb line and laser generator connection status schematic diagram；
Fig. 3 is that laser receives plate structure schematic diagram.
Specific implementation mode
As shown in Figs. 1-3, a kind of open caisson construction testing apparatus for verticality, including holder 2, reference plate 3, plumb line 4, swash
Optical generator 5 and laser receiver sheet 6, at 1 top 100mm of open caisson surrounding be evenly arranged four holders 2, four institutes
It states holder 2 respectively to weld together with four reference plates 3, line tail and the reference plate 3 of the plumb line 4 connect
Connect, the lead head of the plumb line 4 is connect with the laser generator 5, at 1 bottom 100mm of open caisson with 2 phase of the holder
Four laser receiver sheets 6 are arranged in vertical corresponding position, and graduated scale 7 is arranged in 6 center of laser receiver sheet, in the scale
7 centrally disposed centring hole 8 of ruler；7 precision of the graduated scale is 1mm, and 8 pore size maxima of the centring hole inclines with code requirement open caisson
Slope maximums are corresponding.
Work progress is as follows：Open caisson carries out segmented construction；After first segment well sinking to projected depth, under starting
Heavy second section open caisson installs laser generator 5 on second section open caisson and carries out examination tune, as second section open caisson is continuous
Sink, starts laser generator 5 and emit laser, laser is incident upon on the laser receiver sheet 6 of first segment open caisson.When first segment is heavy
When the vertical verticality of well and second section open caisson meets code requirement, laser can be in first segment open caisson laser receiver sheet 6
In centring hole 8；If laser deviates from the centring hole 8, illustrate that there are one between first segment open caisson and second section open caisson
Constant inclination tiltedly and be more than code requirement gradient, according to laser projection point at a distance from centring hole 8, to open caisson be adjusted with
Meet verticality requirement.
