Abstract

The utility model discloses a concrete fragment combined inspection well belonging to municipal civil engineering. Different types and sizes of concrete fragments are prefabricated in a factory, carried to a construction site and then combined and installed on a made concrete cushion from bottom to top according to the requirement of a designed construction drawing, cross sections are filled with cement mortar or polymer mortar, and vertical sections are grouted after being connected by U-shaped reinforcing steel connecting nails; the concrete fragments are matched by using concrete regulating slices to joint with a well cover; and a well wall can be drilled for the installation of a pipeline and a crawling ladder. The concrete fragment combined inspection well is an inspection and valve well suitable for water supply, water drainage, rainwater drainage, fire fighting and the line in the diameter (side length) range of 1000 mm to 3000 mm and the depth range of 6 m. The concrete fragment combined inspection well has the advantages of safe and labor-saving operation of workers, quality improvement, energy saving and environmental protection due to the elimination of clay bricks, carrying cost saving and reduction of manufacturing cost.

Description

Burst combination concrete inspection well

Technical field:

The utility model relates to construction work, particularly relates to a kind of civil works manhole.

Background technology:

Sink hole in the construction work, valve well, fire-fighting well and road rain water well etc., the existing loam bricks that adopt are built by laying bricks or stones more, adopt cement mortar as binding material.Loosely organized, anti-leakage is poor.Though concrete prefabricated cylinder well was arranged in recent years, and structural element heavily transports the installation cost height.For example: 1 meter of diameter, the prefabricated water manhole down of dark 2 meters cylinder, expense is about 1200 yuan of one cover, but freight is finished average more than 200 yuan, and energy consumption is bigger.

The utility model content:

The purpose of this utility model is to overcome the problem of above-mentioned existence, and a kind of high-strength concrete burst combination well is provided.Energy-conserving and environment-protective have been eliminated highly energy-consuming, waste soil, have been destroyed the loam brick (traditional manhole material) of environment.Anti-permeability performance, corrosion resistance, the structural integrity of various manholes have been improved.Build well than loam brick and improved operating efficiency more than 5 times.Save at least 5 times of freights than concrete prefabricated cylinder well, and saved hoisting machine tool.It is strong that the absolute altitude adjustability is installed, workman's job safety.Its construction costs saves about 15% than brick well of clay and concrete cylinder well.

Concrete technical scheme of the present utility model is: with the square concrete inspection well of different-diameter circle or different size, scope by height 200mm to 400mm, divide 2 to 5 (circle well or longest edge length are less than 1200mm side's wells within the diameter 1200mm) or divide 6 to 10 (circle well or longest edge length are less than 3000mm side's wells within the diameter 3000mm), burst is prefabricated in factory.The burst wall thickness is according to manhole buried depth and girth.The thickness that is divided into light-duty 60mm to 80mm, be suitable for well buried depth 4M with interior and girth less than 3.5M; The thickness of heavy 80mm to 120mm, be suitable for well buried depth 6M with interior and girth less than 12M.Simultaneously be positioned at well and vertically dock the edge joint mouth, be made as V-type groove shape in advance at the per minute sheet.And stay diameter 16mm connecting hole at the distance egress edge 100mm spacing 200mm of place, and burst height 200mm stays a connecting hole in the centre, and burst height 400mm stays two connecting holes at middle (height 1/4th and 3/4ths places).Burst is positioned at well and laterally is the sawtooth mouth to edge fit is prefabricated, so that butt joint firmly.On-the-spot burst is made up using then, make staple with diameter 14mm reinforcing bar during combination and hammer into connecting hole, pour into 1: 2 cement mortar or polymer bonding mortar (specific (special) requirements person is arranged) in the groove.Need cover the standard manhole cover as well head, so can be under the distance well lid the prefabricated single face closing in of aggregate erection concrete arc burst in the scope of the 500mm left and right sides.After group is good, cooperate installation with well lid with adjustment sheet.

Description of drawings:

1: two burst circle of accompanying drawing well group closes schematic diagram

2: three bursts (many bursts) of accompanying drawing circle well group closes schematic diagram

3: two burst side's well groups of accompanying drawing close schematic diagram

4: four square well groups of burst (many bursts) of accompanying drawing close schematic diagram

Accompanying drawing 5: combined inspection well generalized section

Accompanying drawing 6: adjustment sheet shape figure

Among the figure: 1, well lid 2, closing in arc burst 3, common burst 4, burst with holes 5, connected nail hammer in the hole 6, butt joint v-depression hole.7, adjustment sheet thickness 3mm to 6mm.

The specific embodiment:

The utility model is the high-strength concrete member, and all types of concrete burst strength marks are greater than C30, prefabrication, on-the-spot aggregate erection.The contrast accompanying drawing, its concrete mode of implementing is: at the scene according to pipeline elevation and direction requirement, carry out the thick label C15 of the macadam upper berth 100mm concrete cushion of 100mm thickness earlier, than the big 100mm in well outside.Calculating inspection well height, directly combination tipping at the scene after examinations such as the common burst of differing heights, arc burst, burst with holes, connected nail are joined, erection sequence: upright burst 4 → nail connected nail 5 → corrections → grouting hand-hole 6 → tiling is starched and is found

upper strata burst

3,2 → follow closely connected nail 5 → correction → grouting hand-hole 6 → arrive design height.Grouting is with 1: 2 cement mortar or polymer mortar.For accurately cooperating installation, when being installed, burst should carry out the adjustment seat slurry with adjustment sheet 7 when well lid 1 is installed and connect than the low 50mm to 100mm of design altitude with well lid 1.Borehole wall available water is bored to punch and is cooperated with piping erection.

The utility model combination burst manhole meets the environmental protection and energy saving principle, has eliminated the loam brick of backward power consumption.The recruitment time is shorter, cost saving, and construction safety is convenient to operation.
