The construction of the waterproof construction of the retaining design high-low bay sole plate of gravity dam retaining wall 100 provided by the utility model
Method, comprise the following steps：
The first step, soil mass of foundation pit excavation is paramount to excavate absolute altitude across the soil body 201, in height across the soil body 201 and gravity dam retaining wall
100 top pour it is high across concrete cushion 210, it is high across concrete cushion 210 and gravity dam retaining wall 100 together as it is low across
The retaining design that the soil body 301 excavates, it is ensured that the low deep pit monitor when soil body 301 excavates is stable.
Second step, soil mass of foundation pit be excavated to it is low across the soil body 301 excavate absolute altitude, pour low across concrete cushion 310.
3rd step, the sidewall surfaces of gravity dam retaining wall 100 are flattened.First, in the side wall of gravity dam retaining wall 100
Upper progress steel wire 101 is constructed, and can be fixed with steel nail.Then, sprayed in the side wall of gravity dam retaining wall 100 using wet-spraying machine
Concrete, form shotcrete layer 102.Spraying operation using segmentation, burst, be layered and carry out successively, injection order from lower and
On, low-lying place is first substantially sprayed to flat, then sequence from low to uper part layering, reciprocal injection, concrete is injected gravity dam retaining wall 100
Gap, fill facial pocket, glue concrete and gravity dam retaining wall 100 and be linked togather.Afterwards, in shotcrete layer
102 surface is done one of cement mortar and plastered again, forms side wall screed-coat 110, and side wall screed-coat 110 has smooth-going surface, just
In subsequent construction.
4th step, carry out waterproof coating and waterproof coiled material construction.First, it is low across sole plate 300, height across sole plate
200 and the side wall of gravity dam retaining wall 100 on, while carry out the brushing construction of water-repellent paint, formed integral low across waterproof coating
320th, height is across waterproof coating 220 and side wall waterproof coating 120.Then, paving is low successively rolls up across waterproof roll 330, side wall waterproof
Material 130 and high across waterproof roll 230, make low from bottom to top to take in the side wall bottom of gravity dam retaining wall 100 across waterproof roll 330
Certain altitude is connect, lap segment one is formed with the side wall waterproof roll 130 of rear construction；It is high across the horizontal laying of waterproof roll 230 and by
It is above lower to lay to certain altitude in the side wall of gravity dam retaining wall 100, lap segment two is formed with side wall waterproof roll 130, so as to
It is high across waterproof coating 220, it is side wall waterproof coating 120, low across the completely paving of waterproof coating 320 and mutually close overlap joint, formed effectively anti-
Water layer.
5th step, pour high across pea gravel concreten protective layer 240 and low across pea gravel concreten protective layer 340.
6th step, carry out low across sole plate 300, the high reinforcing bar colligation across sole plate 200, high-low bay foundation beam 400
Operation, and high-low bay foundation beam 400 with the low construction joint 401 across sole plate 300 fix together with elongated steel plate for sealing water
410, then pour the low concrete across sole plate 300, and low at construction joint 401 is mixed across the top layer of sole plate 300
Solidifying soil is arranged to zigzag.In construction, it should ensure that steel plate for sealing water 410 is embedded to and low be not less than across depth in sole plate 300
10cm。
7th step, it is low after sole plate 300 reaches strength of mould stripping, the side form that mould installs high-low bay foundation beam 400 is hung, is poured
High-low bay foundation beam 400 and height are built across sole plate 200.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belonging to right will
Seek the protection domain of book.
