Introduction: When the waterproof casing pipe is hoisted and put into the groove, the reliable soft belt sling shall be selected, and the trench shall be laid smoothly without violent collision with the groove bottom and wall. In order to ensure the accuracy of the pipe laying position, it is necessary to place the middle part in the pipe

Waterproof casing When the pipe is hoisted and put into the groove, the reliable soft belt sling shall be selected, and the trench shall be smoothly lowered without violent collision with the groove bottom and groove wall. In order to ensure the accuracy of the pipe laying position, it is necessary to place a horizontal ruler with intermediate scale in the pipe. During the inspection, it is necessary to check whether the middle pull wire sagging on the middle line of the pipeline coordinate coincides with the middle of the level ruler.
Common waterproof casing is divided into rigid and flexible. Attention should be paid to the selection: the waterproof casing is manufactured according to S312, 02s404 standard atlas developed and designed by the Institute of building science. Rigid waterproof casing The installation of waterproof sleeve for drinking water pool shall be carried out after the completion of stone wool concrete filling. When the sealing paste is filled, all surfaces in the joint shall be free from rust, bright skin and dirt, and shall be clean and dry. It is generally applicable to buildings where the pipeline passes through the wall and is subject to vibration or strict waterproof requirements; if the wall passing through the wall is not concrete, it is necessary to use concrete wall, and the casing must be condensed in the wall at one time; the waterproof sleeve is applied to the construction, chemical plant, steel, drinking water, sewage treatment and other units.
Rigid waterproof casing is steel pipe with flange ring (steel plate made of annular sleeve on steel pipe), installed in the wall (see concrete wall), used for general pipe through the wall, conducive to the waterproof of the wall Flexible waterproof casing In addition to the external wing ring, there are also baffle rings inside. The flange inner thread is sold by a complete set of equipment, and can also be produced and processed by ourselves to meet the needs of shock absorption, such as when the pipe connected with the water pump passes through the wall.
It is forbidden to throw or collide violently during transportation, loading, unloading and stacking of waterproof casing pipes. The pipeline pavement can be carried out only after the groove inspection reaches the standard. Before the pipeline laying, the appearance inspection of the pipe and pipe fittings should be conducted once again, and the pipes and fittings with problems found shall not be used.
When the pipeline passes through three joints (expansion joint, settlement joint and anti vibration joint), in order to ensure that the pipeline will not be broken or twisted due to uneven settlement on both sides of the three joints of the building, generally, casing pipe should be set. This type of casing usually has unique requirements. It can be customized according to the design requirements.
