Description
Technical field
Changed the outfit technique the present invention relates to well lid technical field of construction, especially a kind of anti-settling inspection shaft.
Background technology
The inspection shaft that the solid clay brick for commonly using at present is built by laying bricks or stones, low intensity, water penetration are high, use table after a period of time
Skin comes off loose inside, causes well body integral sinking, periphery roadbed subsidence, as road engineering in a big common fault, thus produce
Raw potential safety hazard, inspection shaft hurt sb.'s feelings, the damage accident of vehicle happens occasionally.
In addition, cement pressed brick is similar to clay brick, intensity is not reached, and connectivity is poor, and assembling type device for detecting manhole is conducted oneself with dignity
Heavier, assembled difficulty is big, it is necessary to installed with loop wheel machine, cumbersome.
The content of the invention
Changed the outfit technique it is an object of the invention to provide a kind of anti-settling inspection shaft, replace original old-fashioned inspection shaft, changed the outfit
The anti-settling inspection shaft of Cheng Caiyong corrosion-resistant anti-compressions, high intensity.
The technical scheme is that：
A kind of anti-settling inspection shaft changes the outfit technique, it is characterized in that comprising the following steps：
Step 1) prefabricated anti-settling concrete cover (1), anti-settling concrete cover (1) is reinforced concrete structure；
Step 2) road surface cutting：Centered on well room, increase per side according to the size of anti-settling concrete cover (1)
The length of 200mm carries out cutting road surface, removes original well cover frame, and dabbing treatment is carried out to surrounding；
Step 3) Jing Zhou basic units crushing and clearing：According to the feelings such as original pavement of road, basis, inspection shaft and surrounding, well room
Condition excavates downwards 45-55CM along blacktop, and the adjustment of pit shaft absolute altitude is carried out with modular brick or concrete brick；And to pit shaft week
Tamped with battering ram on the basis on side；
Step 4) pea gravel concreten bed course (11) construction：By basic unit's bottom leveling, compacting after excavation, and surrounding basis
Backfilled using two ashes, Yong Shang Quan are levelling, the difference in height on after basis is finished and ground is 300mm, and levelling absolute altitude is higher than pit shaft
50mm；
Step 5) anti-settling concrete cover (1) and well lid (4) installation：After pea gravel concreten bed course (11) tentatively solidification
Lift immediately, anti-settling concrete cover (1) is in place, the hole to be provided of rear holding pit shaft in place and anti-settling concrete cover (1)
Mouthful (2) with one heart, anti-settling concrete cover (1) side parallel to direction of traffic, and anti-settling concrete cover (1) lower surface with
Pea gravel concreten bed course (11) contact is closely knit, and anti-settling concrete cover (1) upper level is less than asphalt concrete pavement
10mm, it is ensured that bituminous concrete laying depth, additionally, the size according to well lid base (3) upper limit ring (5) determines that bolt is fixed
The position of mouth, on anti-settling concrete cover (1), gets 4 holes of symmetrical diameter 18mm, then fixed with expansion bolt
Spacing ring (5), well head is concentric with walling crib；
Step 6) changeover portion asphalt concrete construction around anti-settling concrete cover：Bituminous concrete is backfilled into mould
(12) it is buckled on well lid base (3), after bituminous concrete backfills mould (12) in place, in anti-settling concrete cover (1) surrounding
Space with C30 pea gravel concretens fill it is closely knit, bituminous concrete is carried out to well lid base (3) surrounding and is poured, and use equipment
Levelling pitch, well lid and road surface (10)；
Step 7) compacting pitch, remaining soil outward transport：Pitch to well room surrounding is tamped, and well lid is put after road surface is recovered
(4) anti-theft bolt (6), is installed and well lid (4) is compacted, road surface is finally cleaned, remaining soil and construction rubbish outward transport completes to change the outfit.
Anti-settling concrete cover (1) middle part offers reserved opening (2).
This has damping washer (9) between the well lid (4) and well lid base (3)
The spacing ring (5) is arranged on well lid base (3).
Well lid base (3) inner ring is provided with anti-theft bolt seat (7), and anti-theft bolt (6) is through well lid (4) and anti-theft bolt
Seat (7) is threadedly coupled with anti-theft nut (8) afterwards.
It is tubbiness that the bituminous concrete backfills mould (12), and top is cone cylinder (13), bituminous concrete backfill mould
(12) be respectively provided on two sides with handle (14).
The beneficial effects of the invention are as follows：
Anti-settling inspection shaft of the invention changes the outfit construction technology simply, saves the time, is easy to operation, and traffic current is influenceed
Smaller, the old-fashioned well lid for being applicable to vast both urban and rural area changes the outfit.
After changing the outfit, sedimentation will not be produced, effectively prevent disaster from occurring, and with service life more long.
Short construction period, destroys small to pavement of road, and underground pipe network also can be protected effectively, and backfilling process is accurately tight
It is close, with original road surface holding level after changing the outfit, the drawbacks of overcome low-lying deformation.
Using particular manufacturing craft, technique is accurate, the no-float between well lid, it is not easy to deformation, the well lid after changing the outfit occur
Combined together with road surface, it is elegant in appearance.
