Abstract
The invention provides an inspection ruler for a round inspection well. The inspection ruler comprises a first straight rod and a second straight rod, wherein one end of the second straight rod is hinged in the center of the first straight rod; the length of the second straight rod is half that of the first straight rod; the first straight rod is provided with a telescopic joint I and a telescopic joint II which extend out from two ends of the first straight rod; the second straight rod is provided with a telescopic joint III extending out from the outer end of the second straight rod; and scales are formed on the telescopic joint I, the telescopic joint II and the telescopic joint III by taking respective outer end as reference. In the process of constructing the round inspection well, the telescopic joint I, the telescopic joint II and the telescopic joint III extend at the same length, so that the total length of the first straight rod, the telescopic joint I and the telescopic joint II equals to the sum of the inner diameter of the inspection well and twice plaster thickness, the first straight rod, the telescopic rod I and the telescopic rod II are erected on the pre-construction position, and bricks are laid, so that whether the internal opening of the inspection well is round or not can be inspected by rotating the second straight rod, and the construction quality can be guaranteed.
Description
Technical field
The present invention relates to a kind of circular inspection chamber and build utility appliance by laying bricks or stones, be specifically related to a kind of circular inspection chamber detection ruler.
Background technology
The brick inspection chamber of tradition is meant maintenance for underground foundation facility (like power supply, feedwater, draining, communication, gas pipe, street lamp etc.), all kinds of inspection chambers that the installation aspect is provided with, observe all kinds of well in operations of well etc., and its function is to make things convenient for equipment inspection, maintenance, installation.
Circular brick is built inspection chamber by laying bricks or stones and in work progress, is adopted " bag heart masonry method " usually, and interior week completely is paved with crowded with brick, between periphery brick and the brick with full pointing with cement mortar.But in work progress; Randomness is bigger because the workman constructs; Pit shaft often occurs and build circle, wellbore centre line and chute vertical angle by laying bricks or stones and produce deviation, pit shaft every layer of brick when closing in and take in problems such as size is inconsistent, have a strong impact on inspection chamber presentation quality and structural safety.
Summary of the invention
The technical matters that the present invention will solve provides a kind of circular inspection chamber detection ruler, in construction, uses its control inspection chamber circularity.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:;
A kind of circular inspection chamber detection ruler; Comprise first straight-bar and second straight-bar; Second straight-bar, one end is articulated in the first straight-bar midpoint, and the length of second straight-bar is the half the of the first straight-bar length, and first straight-bar also has the telescopic joint I and the telescopic joint II of stretching out from its two ends respectively; Second straight-bar also has the telescopic joint III of stretching out from its outer end, telescopic joint I, telescopic joint II and telescopic joint III all with they separately the outer end be that benchmark indicates scale.
Above-mentioned circular inspection chamber detection ruler, the length of said second straight-bar is 40cm, telescopic joint I, telescopic joint II and telescopic joint III are 30 cm.
Above-mentioned circular inspection chamber detection ruler; Said telescopic joint I outer end portion end face stretches out; Extension and outer end section form jointly and can be supported in De “ ∟ on the well bore " v notch v; said telescopic joint II outer end portion end face stretches out, and extension and outer end section form jointly and can be supported in De “ ∟ on the well bore " v notch v.
Above-mentioned circular inspection chamber detection ruler, said pin joint place also is provided with line and weighs down.
Above-mentioned circular inspection chamber detection ruler, said line weigh down and are the line bob that can bounce back.
In circular inspection chamber building process; Telescopic joint I, telescopic joint II and telescopic joint III are stretched out identical length, make first straight-bar, telescopic joint I and telescopic joint II length summation equal inspection chamber internal diameter and the twice thickness sum of wiping one's face, and are set up in preparatory construction place; Put this layer brick then; Through rotating second straight-bar, whether the internal orifice that can detect inspection chamber is justified, and guarantees construction quality.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a structural representation of the present invention.
Among the figure: 1 extension, 2 telescopic joint I, 3 first straight-bars, 4 pin joints, 5 telescopic joint II, 6 second straight-bars, 7 telescopic joint III, 8 lines weigh down.
Embodiment
As illustrated in fig. 1 and 2; A kind of circular inspection chamber detection ruler comprises first straight-bar 3 and second straight-bar 6; Second straight-bar, one end is articulated in the first straight-bar midpoint, and the length of second straight-bar is the half the of the first straight-bar length, and first straight-bar also has the telescopic joint I 2 and telescopic joint II 5 of stretching out from its two ends respectively; Second straight-bar also has the telescopic joint III 7 of stretching out from its outer end, telescopic joint I, telescopic joint II and telescopic joint III all with they separately the outer end be that benchmark indicates scale.
Concrete a kind of size, the length of said second straight-bar is 40cm, telescopic joint I, telescopic joint II and telescopic joint III are 30 cm.
Be placed on relative two bricks of inspection chamber with one deck in order to make detection ruler to stablize to take easily; Said telescopic joint I outer end portion end face stretches out; Extension 1 forms with the outer end section jointly can be supported in De “ ∟ on the well bore " v notch v; said telescopic joint II outer end portion end face stretches out, and extension and outer end section form jointly and can be supported in De “ ∟ on the well bore " v notch v.
In order to assist to control the position of inspection chamber axis, guarantee that the inspection chamber axis is vertical with chute, said pin joint 4 places also are provided with line and weigh down 8.
Particularly, said line weighs down and is the line bob that can bounce back.
Concrete constructing operation process:
1. build pit shaft by laying bricks or stones, after water washed down the basis, the calculating inspection well internal diameter size and the thickness of wiping one's face transferred to respective length with the main scale high scale, and center line weighs down and overlaps with setting-out inspection chamber center, puts the ground floor brick successively.After seat slurry is put the upper strata brick, build top inspection pit shaft by laying bricks or stones according to above method, accomplish completely to be paved with crowded, brick and brick be with full pointing with cement mortar, assurance inspection chamber well bore globality and rigidity.
2. shaft walling must not have vertical straight joint, is necessary for the upper and lower fissure of displacement, inside and outside overlap joint.Continuing to connect when high, the earth foreign material on the former brick face are cleaned out, water washes down the brick face and soaks into then.Continue afterwards the detection ruler central point is overlapped with the inspection chamber central point, vertical to guarantee this layer brick face with the wellbore centre line.
3. need close up when handling when inspection chamber, detector centre point invariant position, the gradual change of calculating hoisting depth and indentation size by dimensional requirement concerns, makes the closing in of evenly going forward one by one of brick inspection chamber well bore.
