specifically, the cavity between the heat-insulating cover plate 101, the well ring 2 and the well cover 3 is a first air insulating layer; the cavity below the heat preservation cover plate 101 is a secondary air isolation layer; air does not flow between the first air insulating layer and the secondary air insulating layer, and the effect of reducing the speed and the flowing distance of air flow is achieved.
As a further optimization of the present embodiment: the well body 1 is a prefabricated body, and the prefabrication steps are as follows:
step 1: firstly, manufacturing an outer mold for well casting and an inflatable inner mold; before entering the mould, the air is tried to be filled on the ground so as to check whether the inflatable inner mould is damaged and air leakage occurs in the last construction, ensure that the inflatable inner mould is intact, avoid quality hidden trouble in the process of pouring concrete, and uniformly smear release agent on the outer surface of the inflatable inner mould;
firstly, concrete pouring is carried out on the bottom side of the inner part of the pouring outer mold, and when the bottom of the well body is poured out, the inflatable inner mold is fixed on the bottom side of the inner part of the outer mold, and the inflating nozzle is placed outwards; the binding inflatable internal mold needs to adopt a white rice dumpling rope, and the internal mold is not directly contacted by a steel wire rope so as to avoid damage.
Step 2: 1) After the inflatable inner die is in place, an air inlet valve is opened, and the inflatable inner die is inflated by an air compressor; when the pressure reaches the use pressure, (the inflation pressure value of the inner mold is determined according to the model), the air valve is closed, and the inflation is stopped; 2) The inflatable internal mold should be inflated before first use, the sufficient time when each set reaches the use pressure is measured, and the number of the needed air compressors is determined according to the initial setting time of the concrete, so that the vertical ribs of the plate girder and the upper concrete are ensured to be poured before the initial setting of the concrete at the lower part of the vertical ribs, the construction joint is avoided, and the integrity of each plate girder concrete is ensured; 3) The inner mould of the air bag should be inflated alternately until reaching the use pressure, namely the principle of on-off; 4) Note that no overpressure is required during inflation.
Step 3: fixing and pouring concrete: 1) The inflatable internal mold is fixed by using positioning hoop steel bars in order to ensure that the sizes of a well body steel bar protection layer and a well body cavity part meet the design and specification requirements, the internal mold is prevented from floating in the concrete pouring process, the positioning steel bars are welded firmly with plate girder steel bars (the interval between the hoops of the inflatable internal mold with the diameter of 200mm is 80cm, if the diameter is increased, the interval is correspondingly reduced), and the inner diameter of the positioning steel bars is the same as the size of the cavity; 2) The concrete pouring method is basically the same as that of solid construction, and attention is paid to the symmetrical vibration from two sides by using high-frequency inserted or ramming bars so as to prevent the left-right displacement of the inflatable internal mold; the inflatable inner mould is not touched during vibration so as to avoid the loss caused by puncturing the air bag.
Step 4: removing the die: 1) Opening a valve to deflate after the concrete is finally set, and extracting the inflatable inner mold;
2) The extraction time of the air bag internal mold depends on the cement ratio, cement mark and environmental temperature, and the air bag internal mold is observed at any time during construction and extracted at proper time; too early a time can cause sagging of the upper concrete, causing defects in the quality of the concrete; the air-filled internal mold is not easy to be pulled out when the time is too late, and the air-filled internal mold is damaged.
As a further optimization of this embodiment, the inflation pressure of the inflatable internal mold is related to the internal mold diameter, the pressure of newly poured concrete, the construction air temperature and other factors; the internal mold pressure is kept within the range of 0.02-0.025Mpa (round or oval) and 0.012-0.015Mpa (octagon, spherical crown shape and trapezoid), and the aperture of the reserved hole meets the standard requirement, thereby achieving the expected effect.
(2) The air release time of the inflatable internal mold is related to the construction air temperature, and the finger on the surface of the concrete can press out the fingerprint after the concrete is poured, and the concrete can be released without deformation.
(3) When the inflatable internal mold is used, the isolating agent must be brushed to reduce the mold drawing resistance, and engine oil is not recommended to replace the isolating agent, so that on one hand, the engine oil erodes rubber, and on the other hand, the engine oil can pollute the reinforcing steel bars. The effect of the aqueous soap is ideal when the aqueous soap is diluted with the aqueous soap. The ratio of soap (powdered soap) to water is about 1:20
The working principle of the invention is as follows: when the well lid 3 is opened, firstly, the bottom of the rotating rod 41 is inserted into the slot 32, the driving block 43 is inserted into the driving groove at the top of the driving shaft 333, and then the driving block is rotated anticlockwise by 90 degrees, at the moment, the force application column 44 rotates to the bottom of the well lid body 31 and abuts against the well lid body 31, and when the driving shaft 333 drives the half-tooth rotary table 331 to rotate, the two arc-shaped locking arms 35 rotate inwards under the drive of the connecting sheet, so that the two arc-shaped locking arms 35 are unlocked from the locking groove 22; when the half-tooth turntable 331 rotates, the bidirectional rack 36 is driven to slide transversely, and the bidirectional rack 36 drives the rack 39 to move through the gear 38; the first locking hook 37 arranged at the bottom of the bidirectional rack 36 and the second locking hook 310 arranged at the bottom of the rack 39 slide to the inner side of the outer rib 27, so that hooking is prevented when the well lid 3 is opened;
the arc end of the locking bar 341 deflects to one side with the fixed shaft 342 as a rotation center under the toggle of the protruding shaft 344, and the locking bar 341 is separated from the locking groove 22; at the moment, the manhole cover body 31 is lifted upwards by holding the force applying arm 42 by two hands, and the manhole cover body 31 can be turned upwards by taking the hook 311 at the bottom of the manhole cover body as the center, so that the manhole cover 3 is opened;
in the invention, the well lid 3 is locked and fixed with the well ring 2 in a plurality of interlocking modes, so that the well lid has extremely high anti-theft and safety protection effects;
after the well lid 3 is opened, the C-shaped rod 263 is grasped by a hand and pulled to the force application rod 210, the sliding frame 261 can be pulled out of the locking groove 22, so that the locking is released, then the sliding clamping piece 26 is lifted upwards, the side vertical plate 25 is turned upwards by taking the rotating shaft 29 as the rotating center, the protection inside the well ring body 21 can be opened, and a worker can enter the well body 1 to work;
when the well body 1 is covered and protected, firstly, the side vertical plate 25 and the stacking claw 28 are stacked in the locking groove 22, and the C-shaped rod 263 fixes the sliding frame 261 in the locking groove 22 under the pulling of the extension spring 264, so that the locking fixation and protection of the inside of the well ring body 21 are realized; then the well lid body 31 is buckled above the well ring body 21, then the well lid opening assembly 4 is utilized to rotate the unlocking assembly 33 clockwise, and at the moment, the well lid locking piece 34 and the arc-shaped locking arm 35 are both clamped into the locking groove 22 under the drive of the unlocking assembly 33; the first locking hook 37 and the second locking hook 310 are driven by the bidirectional rack 36 and the rack 39 to slide to the position right below the outer rib 27, so that the hooking effect can be achieved when the well lid 31 is forcibly opened, and the safety protection performance is improved.
