The prefab-form (62) of exempting to tear open of side exempts to tear open prefab-form (62) inclination, prefabricated board bottom connecting cross beam relative to the other side
(70) exempt to tear open prefab-form (62) for connecting two sides form a kind of three-legged structure, effectively increase what key-wall template was installed and poured
Globality.
Step 4: installing the concreting of erosion control key-wall, vibrating, scraping device:
After erosion control key-wall template is installed and checked, sliding gate tumbling barrel frame is set in barricade Side shuttering (41) two sides
(49), movable type being set on sliding gate tumbling barrel frame (49) carriage and pouring tumbling barrel (50), the movable type pours tumbling barrel
(50) be slidably disposed on the sliding gate tumbling barrel frame (49) and be vertically arranged, movable type pour connect on tumbling barrel (50) it is mixed
Solidifying soil delivery pipe (74), the concrete delivery pipe (74) pour tumbling barrel (50) interior delivering concrete toward the movable type.
Specifically, the barricade Side shuttering (41) is located in the space that sliding gate tumbling barrel frame (49) is formed,
The movable type pours the barricade Side shuttering that tumbling barrel (50) setting is placed in two sides on sliding gate tumbling barrel frame (49)
(41) between, the movable type pours tumbling barrel (50) and pours cylinder including at least one, is successively arranged vertically downward, the concrete is defeated
Pipe (74) are sent to be located at the top that the movable type pours tumbling barrel (50).
It is that vertical direction setting sliding gate of vibrating is vibrated frame (51), wherein the sliding gate frame (51) that vibrates is set to
Two lateral retaining wall Side shutterings (41), the sliding gate, which is vibrated on frame (51), to be further included vertically disposed moving rail and is connected with
Vibrating spear (52) moving up and down, wherein moving rail setting vibrates in the sliding gate and is placed in two sides on frame (51)
Barricade Side shuttering (41) between, the vibrating spear (52) moves up and down along the moving rail；
It is that barricade Side shuttering (41) two sides setting sliding gate strikes off frame (53), wherein sliding gate strikes off frame (53)
Including vertically disposed connecting plate and be provided with extended position vibration scrape flat-topped ridge (54), wherein the connecting plate setting stretched described
The vibration of exhibition formula, which is scraped, to be placed between the barricade Side shuttering (41) of two sides on flat-topped ridge (54).
It includes scraping flat-topped ridge large scale central sill (56), hanging the flexible side bar of flat-topped ridge small size that flat-topped ridge (54) are scraped in the extended position vibration
(57), side bar bottom plate (58), fixation hole (59), fixed peg (60) strike off beam large scale central sill (56) and are connected to wherein described
The connecting plate, the flat-topped ridge small size flexible side bar (57) of hanging are placed in the two sides for scraping flat-topped ridge large scale central sill (56), institute
It states side bar bottom plate (58) and is located at the bottom for scraping flat-topped ridge large scale central sill (56), it is described to scrape shape on flat-topped ridge large scale central sill (56)
At at least two fixation holes (59), the fixed peg (60) passes through the fixation hole (59) fixed described extended position vibration and scrapes flat-topped ridge
(54) and flat-topped ridge (54) are scraped in extended position vibration.
Step 5: the concreting of erosion control key-wall and maintenance:
The step 4 after the installation is completed, start casting concrete, concrete pours tumbling barrel (50) by movable type and pour
It builds, vibrates, strikes off when pouring, inside concrete is vibrated by the external vibration board of template, and inside strikes off stretching, extension extended position
Flat-topped ridge (54) are scraped in vibration, are poured more up gradually to inside contract and are scraped flat-topped ridge.Key-wall uses C20 concrete, and key-wall surface slope is 1:
0.3.It is conserved after the completion of key-wall concreting, reaches demoulding after some strength.
Step 6: backfill sandy gravel:
After the completion of the construction of erosion control key-wall, cleaning surface soil (73) thickness is about ± 0.5m, then starts sandy gravel and fills (4),
It fills sandy gravel and fills (4) on the removing surface soil (73), sandy gravel maximum stone grain diameter is less than 30cm, contains less than 5mm particulate
Amount is less than 0.075mm grogs content less than 3%, must not contain organic matters and the fertile soil such as weeds, tree root, construction less than 30%
Before should carry out pilot production, earth and stone material lift height is not more than 50cm, need to guarantee that relative density is not less than 0.7 after rolling.It fills out
It builds to desired height and the gradient.
Step 7: back side slope surface is constructed:
After the completion of sandy gravel backfill, form the protection main body of a terraced shape, backwater slope surface is carried out it is smooth, after spread respectively
If 300g geotextiles (10), 15cm thickness sand bedding course (11) and 20cm thickness M7.5 grout six rib block of C20 precast concrete, backwater
The face gradient is 1:2.
Vibration dense body system is struck off by sliding rail sand bedding course cloth positioned at the sand bedding course (11) of backwater slope surface and is laid with completion.
It includes track (15), sole-plate (16) and sliding that the sliding rail sand bedding course cloth, which strikes off vibration dense body system,
Formula cloth bucket (18) composition.
The track (15) is laid on the sole-plate (16) and is fixed, and is placed in the anti-seepage geotextile (10)
On, as shown in Fig. 2, the sole-plate (16) spaced and parallel setting, the track (15) is fixed on the sole-plate (16)
