Abstract

The utility model relates to the well ladder for cable manhole, and being specially can depth measurement cable manhole ladder.Can depth measurement cable manhole ladder, comprise well ladder body, on a column of well ladder body, be fixed with length scales, length scales is made by water wetted material, and length scales by pulling rivet riveting on column.During use, this well ladder stretched to lower cable manhole and landed, and making the column that is fixed with length scales touch the borehole wall, the right scale label in well head edge is well depth; During cable manhole maintenance, need the measuring well internal water accumulation degree of depth, this ladder straight cutting ponding is visited the end of to, ponding liquid level is depth of accumulated water to scale; The utility model provide a kind of can depth measurement cable manhole ladder, the beneficial effect that this well ladder has is: 1. ladder is gone into the well and halted, and just knows well depth; 2. improve operation work efficiency; 3. without other well depth measuring tool.

Description

Can depth measurement cable manhole ladder
Technical field
The utility model relates to the well ladder for cable manhole, and being specially can depth measurement cable manhole ladder.
Background technology
After underground transmission completion of works, when cable manhole is checked and accepted, measuring well deep-well wide; After cable manhole puts into operation, maintenance meets shaft bottom ponding, need know depth of accumulated water, so cable manhole all relates to depth survey when checking and accepting and overhaul.Current practice is that ascending stair is used ruler measurement after going into the well, and therefore goes to work and wants multi-band one ruler, and in well, grasp chi and measure because of narrow space, measures inconvenient.
Summary of the invention
The utility model, in order to solve cable manhole when checking and accepting and overhaul, is measured inconvenient problem because of narrow space behaviour chi in well, and providing can depth measurement cable manhole ladder.
The utility model is to adopt following technical scheme to realize: can depth measurement cable manhole ladder, comprise well ladder body, and on the cylinder passing through of a column of well ladder body, be fixed with length scales.
During use, this well ladder stretched to lower cable manhole and landed, and making the column that is provided with length scales touch the borehole wall, the right scale label in well head edge is well depth; During cable manhole maintenance, need the measuring well internal water accumulation degree of depth, this ladder straight cutting ponding is visited the end of to, ponding liquid level is depth of accumulated water to scale; Utilize this well ladder can carry out easily the measurement of data in cable manhole, while going to work, also do not need to be separately with ruler, therefore also can not have the inconvenient problem of utilizing ruler measurement to bring.
Above-mentioned can depth measurement cable manhole ladder, length scales is made by water wetted material, the length scales chi face of water wetted material easily gets wet, can Measurement accuracy depth of accumulated water.
Above-mentioned can depth measurement cable manhole ladder, length scales on column, guarantees that length scales is fixed by pulling rivet riveting.
The utility model provide a kind of can depth measurement cable manhole ladder, the beneficial effect that this well ladder has is: 1. ladder is gone into the well and halted, and just knows well depth; 2. improve operation work efficiency; 3. without other well depth measuring tool.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-well ladder body, 2-length scales.
The specific embodiment
Can depth measurement cable manhole ladder, comprise well ladder body 1, on the cylinder passing through of a column of well ladder body, be fixed with length scales 2.
Above-mentioned can depth measurement cable manhole ladder, length scales 2 is made by water wetted material.
Above-mentioned can depth measurement cable manhole ladder, length scales 2 by pulling rivet riveting on column.
