Abstract

The title of the invention is integral assembly reinforced concrete prefabricated draining inspection well. The invention belongs to the technical field of municipal drainage. By means of the inspection well, the problems that traditional inspection wells have poor integrity and pipeline elevation cannot be adjusted at will are solved. Assembly parts with different heights are assembled by different assembling modes to solve the problem that drain pipes cannot be totally assembled due to their different heights. Assembled by different combination modes, each inspection well can be prefabricated by reinforced concrete.

Description

The overall prefabricated drainage inspection well of assembled armored concrete

Technical field

Town road draining

Background technology

Inspection shaft is used in buried concrete drain pipeline in the range of public building district, plant area, highway etc., the depth of burying is not more than 6m, be generally located at drainage pipeline intersection, turning, caliber or gradient change, at drop etc., for the ease of make regular check on, clean and dredge or down-hole operation inspection with brick become or the well shape structures of concrete block masonry.Being mostly building block inspection shaft in the market, existing precast splice type armored concrete inspection shaft entirety imperfection, the duration is longer.

Summary of the invention

Φ 600 bell and spigot straight line right-angle tee four-way Φ 1000 circular inspection well can be made into several specification, mixes variable-diameter joint and can obtain any elevation of pipeline.Variable-diameter joint flexibly connects with precast concrete pipe, simple installation, and speed is fast.The same day lays pipeline, can backfill the same day, the reduction of erection time.Reduce cost.

Detailed description of the invention

Factorial praluction, in-site installation.The thick particle diameter in 10 centimeters of inspection shaft base plate lower berth is less than 10mm aggregate.As required can assembled 300-600 prefabricated reinforced concrete pipe, can be selected for any variable-diameter joint and install, a kind of caliber of choosing connects.The well bore part of different size can be installed in well seat top.Bell and spigot uses rubber ring V-type and O type.May select the assembly of prefabricated two-way linear 300 bell and spigot well bore at receipts water pipe or C40 concrete brick is built by laying bricks or stones.Build more convenient dirt by laying bricks or stones to roll.Mark time bar diameter 16mm, wide 150mm, exposes 100mm, horizontal positioned, bends, vertically anchor 150mm in the borehole wall.

Using 100 years, concrete uses C40.Seepage-resistant grade is S8.Reinforcing bar uses CRB550, HPB300.Cover to reinforcement 35mm；Bell and spigot end reinforcing bar 20mm.Mortar uses M15.

Inspection shaft each part dimension deviation is fit dimension deviation+0.5mm to-0.5mm；Non-fit dimension+2 is to-1.

Assembly form is shown in accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, and variable-diameter joint is installed and seen accompanying drawing 5.
