Layer, effect is to prevent the immersion of water from causing after well body firm banking is corroded, to reduce anti-floating performance, cause under well body
It is heavy, so as to have impact on the service life of well body.
The fixed structure and construction method of described galss fiber reinforced resin concrete open caisson cylinder, its construction method step
Suddenly it is：
The first step, preparation need to prepare neat following construction tool, long-armed digging machine, lifting machine；Electric welding machine (contains welding rod)；
Generator, sewage pump, pine, ratchel, reinforcing bar, concrete etc..
Second step, arranges platform, accurate open caisson position, it is therefore an objective to prevent ground uneven, causes cylinder to occur after placing askew
Tiltedly not just；Lifting rope is fixed on the bottom cylinder suspension ring for having installed water-swellable cushion rubber and adapter sleeve using hoisting machine after smooth
On, by bottom cylinder insert platform place it is smooth after, using long-armed digging machine to bottom inner barrel implement excavate, with excavation
Progress, bottom cylinder is voluntarily sunk due to the weight of itself；Adapter sleeve on the cylinder of bottom will be higher by 5~40cm of platform, sink
During to specified location, just stop excavating；
3rd step, is fixed on lifting rope using hoisting machine and has installed the middle cylinder of water-swellable cushion rubber and adapter sleeve and hang
On ring, the water-swellable cushion rubber on the bottom set of middle cylinder is then coated with lubricating oil, is so easy to middle cylinder to enter bottom
Adapter sleeve on cylinder, is linked together the bottom of middle cylinder with bottom cylinder using adapter sleeve；Then in bottom cylinder
The built-in pre-buried steel part and suspension ring on inner side top make bottom with being welded to connect muscle on the built-in pre-buried steel part of middle cylinder inner lower edge
End cylinder is connected two-by-two with middle cylinder；Install after middle cylinder, the height at measurement record cylinder upper end Haikou is found out minimum
Point and peak, calculate its drop, drop is not more than 5cm, to be rectified a deviation more than after 5cm；Then carried out using long-armed digging machine
Excavate, with the progress excavated, bottom cylinder is sunk jointly with middle cylinder, the adapter sleeve of middle cylinder will be higher by platform 5
~40cm, due to the quantity of middle cylinder 2 can be caused under different well body depth profiles different, but a upper section middle cylinder with
When next section middle cylinder installs connection, a section middle cylinder should be made to be arranged on next section middle cylinder adapter sleeve, then
The pre-buried steel part built in top on the inside of pre-buried steel part built in upper one section middle cylinder inner lower edge with next section middle cylinder
With on suspension ring on be welded to connect muscle, make one section middle cylinder with it is next save middle cylinder be connected two-by-two；
4th step, it is using hoisting machine that lifting rope is solid on the cylinder suspension ring of top, meet water on the bottom set of top cylinder
Cushion rubber is expanded, and coats lubricating oil, top cylinder is loaded on the adapter sleeve on middle cylinder, by top cylinder and middle cylinder
Link together, then on the inside of middle cylinder built in pre-buried steel part and suspension ring built in top and top cylinder inner lower edge
Muscle is welded to connect on pre-buried steel part, middle cylinder is connected two-by-two with top cylinder, and whole well body is fixed together；
Install after the cylinder of top, the height at measurement record cylinder upper end Haikou finds out minimum point and peak, calculates its drop, fall
Difference is not more than 5cm, long-armed digging machine is being utilized more than after being rectified a deviation after 5cm, to well body inner excavation；Now whole well body
Because the progress and own wt of excavation can be sunk together；Until whole well body sinks to finishing；
5th step, underground is inserted using long-armed digging machine by timber, and its timber will basset 20~80cm, to strengthen timber
Stress strength and stability 20~80cm stone can be filled between timber and timber, and smash flat using equipment,
Strengthen the exposed timber stress strength and stability energy in ground surface, improve the firm performance of the soil layer of well body bottom；Prevent well
Body continues to sink to producing dislocation or displacement due to own wt；
6th step, lays stone concrete back cover reinforcing structure layer, and mixed stone with vibrator on robust structure layer
Removal of bubbles in solidifying grave bottom reinforcing structure layer, can combine concrete compaction, eliminate voids and pits of concrete etc. existing
As to improve its intensity, it is ensured that the quality of concrete component；
7th step, starts to lay reinforcing bar, the laying of reinforcing bar should be noted that between reinforcing bar and reinforcing bar in the upper and lower side of anti-floating square steel
If intersecting dislocation laying dried layer, net-shaped is constituted；Casting concrete after the completion of reinforcing steel bar laying；And with vibrator by stone concrete
Removal of bubbles in back cover reinforcing structure layer, combines concrete compaction, eliminates the phenomenons such as the voids and pits of concrete, to improve
Its intensity, it is ensured that the quality of concrete component；Then Corrosion Protection of Fiber Reinforced Plastics permeable formation is laid on reinforcing bar armored concrete enhancement layer,
Prevent the permeating corrosion of water；
8th step, finally after well body firm banking is built up, the anti-heavy footstock of one week armored concrete is laid around top cylinder,
And anti-heavy fixed steel is fixed in anti-heavy footstock, prevent cylinder from sinking.
Patent of the present invention, improves the performances such as steadiness, anti-floating and the anticorrosion infiltration of well body, strengthens cylinder and cylinder
The stability of body connection, has ensured that a upper section cylinder will not fall off or misplace partially with next section cylinder in cylinder sinking watching
Move, accelerate the speed of open caisson, improve open caisson quality；And shorten construction man-hour significantly, improve operating efficiency.
