Description
Technical field
The utility model belongs to construction equipment technical field, is related to the pile foundation support table construction of building structure, especially
It is related to pile foundation concrete placed under water and cushion cap bottom concrete, is mainly used for controlling concrete placed under water absolute altitude, specially
A kind of simple machine of the underwater concrete absolute altitude of precise measurement.
Background technique
Since the new century, with flourishing for China's building cause, for high-speed railway, highway, high level
The construction investment of the infrastructure such as building, large bridge is increasing, these infrastructure overwhelming majority are all using pile foundation
With campshed supporting, and it is most of require to pour cushion cap bottom concrete, therefore how to control the matter of these underground concealed engineerings
Amount, becomes the problem of engineering construction person need emphasis to think deeply.It is well known that the quality of pile foundation support table is largely and under water
The absolute altitude control of filling concrete is related, in terms of mainly having following two: first is that filling concrete height is too low, being then not achieved and set
Meter requires, and seriously affects bearing capacity of pile foundation, cushion cap is then not achieved the requirement of Resistant heave；Second is that filling concrete height is spent
Height, then cause serious superfilled, not only wastes coagulation soil resource, increases engineering material cost, and abolish increase difficulty to the later period,
Influence construction efficiency.
At present there are two types of more mature technology of the China in terms of measure subaqueous concreting absolute altitude, first is that using
Add the method for plummet with graduated lining rope to estimate filling concrete face absolute altitude, this method to the skill requirement of operator very
Height, and plummet is likely to encounter thicker dross or laitance layer and causes to judge by accident；Second is that underwater concrete is fished for using mechanical equipment,
Perfusion face absolute altitude is judged by rule of thumb by observing concrete composition, and this method needs operator to measure one at regular intervals
Secondary height, troublesome in poeration, labor intensity is larger, and working efficiency is lower.
Utility model content
The purpose of this utility model is the deficiency for above-mentioned measurement method and a kind of more precise measurement for providing is underwater
The simple machine of concrete absolute altitude.
