The inner and outer sides of the reinforcement can be fixed by wood formwork at one time, or the outer side of the pool wall can be built by brick formwork, and the inner side is wood formwork.
It is liquid.
construction of graded crushed stone cushion 1.
2.
During concrete pouring, the concrete shall be vibrated evenly and the surface course shall be flat.
The formwork shall be fixed first, and the thickness of the tank wall is generally 15cm-25cm.

During backfilling, the virtual paving degree shall be controlled to meet the requirements after compaction.
The foundation pit soil shall be excavated in two layers.
The summer palace of huafangzhai, a royal garden in Beijing, has a garden in the garden – Fun garden.
When the temperature of water is reduced or increased, it turns into a solid or gaseous state.
In order to keep the site clean and dry, the accumulated water in the well and the accumulated water in the site must be drained in an organized manner.
After formwork removal, the bolt shall be cut off along the flat concave bottom, and finally sealed tightly with expanded cement mortar.
Elevation control: in order to ensure the reasonable elevation of the base course, control the cost and ensure the construction quality, it is very important to control the thickness of the cushion.
(3) Plug shall be added to the bolt, and plug shall be added on both sides of the bolt during formwork erection.
When the bolt or casing must pass through the pool wall, water stop measures shall be taken.
2.
The plan layout of the pit bottom mainly considers the drainage in the foundation pit during construction in rainy season.
They all seem to be named after water and take water as the theme.
Before concrete pouring, strictly control the height of foundation graded gravel cushion, and it is strictly prohibited to use concrete for leveling, so as to make the concrete reach the same thickness, improve the overall performance and avoid local subsidence.
When the casing is embedded in the concrete, a water stop ring shall be welded on the outside of the pipe, bolts shall be inserted into the pipe, the bolts shall be taken out after the formwork is removed, and the casing shall be sealed with expansive agent cement mortar.
The backfill shall be compacted with frog rammer, and the thickness of each layer shall not be greater than 250mm.
In the warm season, it is liquid, clean and clear.
2.
▶ Clean beauty of water water has clean and pure quality, which is its essential ecological beauty.
2.
The buildings are surrounded by pools and scattered around.
2.
During the construction of protective layer, the construction tools shall be handled with care, and it is strictly prohibited to prevent water and man-made damage..
People can see the pure beauty of water when they think about it.
For the laying of gravel cushion, the gravel of gravel cushion must be mechanically mixed evenly in proportion to achieve the best gradation and can be fully compacted.
Place grid control lines according to the grid diagram and The drawing size describes the shape of the tank body, and the measuring points can be appropriately densified at the place with large radian.
The buildings are named “guiding mirror”, “washing autumn”, “drinking green” and “chengshuangzhai”.
Before the construction of protective layer, carefully check whether there is hollowing in the coiled material.
The earthwork excavated by machinery shall not be stacked on the site, and shall be transported away by dump truck with excavation to avoid stacking.
Before backfilling earthwork, the pipeline embedding shall be thoroughly inspected and accepted before backfilling.
It fills every corner of our life, covers most of the surface of the earth, and is closely related to people’s life.
At the same time, the residual soil shall be cleaned, and the leveling and compaction shall be carried out in strict accordance with the design compaction requirements.
This feature of water is also reflected in Chinese gardens.
Vi.
Lap bonding during waterproof coiled material laying and waterproof treatment after pipeline penetration.
Water is an “unusual” substance.
2.
The construction without filling shall be completed by sections as soon as possible.
construction of waterproof protective layer 1.
The earth shall be excavated in large scale.
Summer Palace – Fun Garden ▶ Technical measures for waterscape construction (including waterproof) Construction process flow} surveying and setting out – earthwork excavation – foundation soil leveling and compaction construction – laying graded gravel cushion construction – concrete foundation cushion construction – brick formwork masonry construction of pool wall (water and electricity installation and embedded construction) – layer construction, waterproof protective layer construction – reinforced concrete construction – stone laying construction of pool surface layer – water and electricity installation – construction, landscape decoration and commissioning – completion acceptance II.
Firstly, the mechanical excavation shall be carried out to the foundation bottom elevation of + 100mm to 200mm, and then the manual excavation shall be carried out.
If there is hollowing, rework the protective layer.
7、 Key points of pool wall construction technology the pool wall generally adopts the vertical form, which has the advantage that the garbage and dust will not be left on the pool wall after being washed by water, so as to keep the pool wall clean.
The fixed formwork adopts iron wire and bolts, which should not directly pass through the pool wall.
IX.
3.
On the East Bank of Beihai, the Royal Garden in Beijing, there is a painted boat Zhai.
Measure and set out datum points according to the appearance, width and plane position of the pool in the site.
“Clear and fresh water” is hung in the main building huafangzhai, which guides people to enjoy the beauty of clouds and clear water in the sky.
Foundation pit backfilling shall be layered and symmetrical to prevent pressure imbalance on one side and damage to the foundation.
earth excavation 1.
One of the above three methods can be selected according to the actual situation.
2.
Measurement and setting out 1.
As the only important element to maintain life, water has never stopped its charm since ancient times.
Its importance can not be ignored.
In front of it, there is a square pool with clear and clean water, which has become the center of the scenic spot.
The project adopts ＾ 20 ＾ thick 1:3 cement mortar waterproof powder waterproof construction, and the construction quality of reinforced concrete cushion shall be controlled, which is strictly prohibited Honeycomb and horse surface appear in the concrete.
It shall be paved and vibrated in layers, and the compactness shall be greater than 90%.
V.
construction of concrete foundation cushion 1.
earthwork backfilling 1.
Waterproof layer construction 1.
2.
First, the quality of graded crushed stone shall be controlled to avoid the mixing of soil and other impurities, and the mixing proportion shall be controlled according to the design requirements.
Waterscape is an indispensable part of the garden and the soul of the garden.
1.
VIII.
During backfilling, control points shall be set in the site first, and attention shall be paid to the protection of control points.
The earth excavation preparation shall be carried out by the combination of machinery and labor.
In the cold winter with extremely low temperature, it solidifies into ice, crystal clear.
IV.
It is proposed to set a water collecting well at the bottom of the foundation pit, and each well is equipped with a submersible pump to discharge the rainwater into the municipal pipeline nearby.
(2) A welded metal water stop ring shall be added to the casing.
