Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As Figure 1-3, a kind of inclined-plane is built plant-growing type eco-concrete anti-overflow device and is comprised bracing frame 1, support frame as described above 1 is cage construction, be the steel square tubes soldering of 80mm or bolt is formed by connecting by the length of side, overall is right angle trigonometry cylinder shape (bracing frame 1 is not limited to right angle trigonometry cylinder shape).The below of support frame as described above 1 is provided with fixing feet 3, described fixing feet 3 is positioned at the both sides (both sides bottom Vierendeel girder length direction upper support frame 1) bottom bracing frame 1, fixing feet 3 is arranged in a right-angle surface (this right-angle surface is as the bottom surface of bracing frame) of the bracing frame of right angle trigonometry cylinder shape particularly, when support frame as described above 1 is placed on Vierendeel girder 10, fixing feet 3 is positioned at the both sides of Vierendeel girder 10, as straddling on Vierendeel girder 10.
Described fixing feet 3 is provided with fastening bolt 4, and bracing frame 1 is fixed on Vierendeel girder 10 by the fastening bolt 4 in fixing feet 3.This device can also fasten on the Vierendeel girder 10 of different in width by the activity of fastening bolt 4, has widened the scope of application of this device.
Support frame as described above 1 is provided with baffle plate 2, and baffle plate 2 is for stopping that concrete overflows, and described baffle plate 2 adopts veneer.Baffle plate 2 is arranged in another right-angle surface of the bracing frame of right angle trigonometry cylinder shape by flitch 7 (size can be 30mm × 30mm × 100mm) particularly, flitch 7 is arranged on bracing frame by set bolt 6, and baffle plate 2 is then fixed on flitch 7 by iron nail 8.
Between described fixing feet 3, the bottom of support frame as described above 1 is provided with batten 9, and described batten 9 is arranged on bracing frame 1 by adjusting bolt 5, and the batten 9 of different-thickness may be used for adjusting elevation.
Show that plant-growing type eco-concrete 11 has built the distance H between rear upper surface and Vierendeel girder 10 top plan according to plant-growing type eco-concrete revetment design manual
1, to measure bottom baffle plate 2 and bottom bracing frame 1 between distance H
2, H
2with H
1difference be H
3, making high (i.e. thickness) is H
3rectangle batten 9.The batten 9 of making is placed in below adjusting bolt 5, and by adjusting bolt 5 by batten 9 and bracing frame 1 fixation.When baffle plate 2 bottom surface and in the same plane near fixing feet 3 bottom surface of baffle plate 2 time, this plane is plant-growing type eco-concrete upper surface absolute altitude chain of command.
The construction of cast-in-place plant growing type eco-concrete bank protection comprises the following steps:
(1) smooth process is carried out to basic unit's soil face of side slope, apply certain fertilizer depending on soil property situation.
(2) pouring reinforcement concrete frame beam, reinforced concrete frame depth of beam should be able to be not less than building highly of eco-concrete and earthing plants raw both sums highly; The sash that Vierendeel girder is formed is of a size of: lateral length is less than 3m, and longitudinal length is less than 2.5m.
The domatic of slope angle 45 ° ~ 70 ° or other are needed to the occasion of anchoring, before pouring reinforcement concrete frame beam, also have anchoring construction:
1) determine position and the angle of bolthole: as shown in Figure 5, the position (i.e. aperture position) of bolthole 13 is arranged on the junction of transverse reinforcement concrete frame beam for building and longitudinal reinforcement concrete frame beam; The angle of bolthole 13 is skewed, and horizontal or longitudinal (for longitudinal in Fig. 5) adjacent two boltholes 13 are one group, and the end often organizing two boltholes 13 is crossing together;
2) bolthole 13 is got out according to the position of the above-mentioned bolthole 13 determined and angle;
3) in bolthole 13 insert send anchor pole 14 body of rod;
4) to grout injection in bolthole 13, two boltholes 13 intersected at end are frozen into entirety.
In conventional anchoring construction process, as shown in Figure 4, two anchor poles 14 are separate, are difficult to carry out anchoring to local is domatic when anchor pole 14 loosens.According to above-mentioned anchoring technique, in two boltholes 13, anchor pole 14 with the cement slurry sets poured into integrally, even if an anchor pole 14 loosens, under the anchorage effect of another anchor pole 14, unless Delta Region 15 entirety formed between two anchor poles 14 loosens, otherwise loosening the domatic of anchor pole 14 anchoring also can not loosen.Like this, under the prerequisite not increasing cost and manpower, the effect of anchoring is greatly improved.
(3) configuration stirs plant-growing type eco-concrete, plant-growing type eco-concrete proportioning: cement 250Kg/m
3, sand 200Kg/m
3, particle diameter is at the rubble 1450Kg/m of 20mm ~ 40mm
3, ZS Series Admixtures 5L/m
3, water 77.5 ~ 90/m
3.
Said ratio is fed in raw material according to the feeding sequence of 1/2 part of rubble, sand, cement, 1/2 part of rubble, stirs 25s in advance, then adds match ratio 1/2 part of water and stir one minute, again by ZS Series Admixtures and 1/2 part of water mixing and stirring, add in concrete, stir 3 minutes, get final product discharging.
(4) according to the length of Vierendeel girder 10 and eco-concrete 11 builds face and Vierendeel girder 10 apical side height is poor, by the baffle plate 2 that size Selection is suitable, and be fixed on flitch 7 with iron nail 8.
Inclined-plane being built plant-growing type eco-concrete anti-overflow device is laterally placed on Reinforced Concrete Beamsin Frame Construction, inclined-plane is made to build the baffle plate gear of plant-growing type eco-concrete anti-overflow device on Reinforced Concrete Beamsin Frame Construction, rotate the fastening bolt in fixing feet, make bracing frame be fixed on Vierendeel girder, the bottom surface of baffle plate is as the absolute altitude control plane of plant-growing type eco-concrete.
(5) plant-growing type eco-concrete be stirred is poured over Vierendeel girder form sash in build, inclined-plane build plant-growing type eco-concrete anti-overflow device block plant-growing type eco-concrete overflow Vierendeel girder, absolute altitude as required paves.
Certainly, inclined-plane also can not be used in the method to build plant-growing type eco-concrete anti-overflow device, directly plant-growing type eco-concrete is poured over Vierendeel girder form sash in build.Such concrete can overflow Vierendeel girder, is unfavorable for construction, also can wastes concrete.
(6) after plant-growing type eco-concrete final set is shaping, unclamp fastening bolt 4, dismounting lower inclined plane builds plant-growing type eco-concrete anti-overflow device, cleaning baffle plate 2, sprays into planting raw thin cultivated soil in the space of eco-concrete with spray gun.
(7) on plant-growing type eco-concrete, carry out earthing construction, the pH value of Sealing soil controls between 6.0 to 7.5.
(8) raw construction is planted: after soil is overlying on eco-concrete surface, carry out broadcasting sowing of seed.
Above-described embodiment does not limit the present invention in any way, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection scope of the present invention.
