井室的混凝土基础应与管道基础同时浇注。

井室的混凝土基础应与管道基础同时浇筑,施工应符合本规范第5.2.2条的要求。

管道穿墙应满足以下设计要求:2.2.2

1混凝土管外壁与砌体井壁孔环连接处为刚性时,水泥砂浆应饱满密实;

2金属压力管道应在井壁孔环内设置套管,管道外壁与套管的间隙四周应均匀,并用柔性或半柔性材料填充;

三。化工建材管道与井壁连接宜采用中间层法;

4现浇混凝土结构井室,井壁孔环应振捣密实;

5排水管与检查井连接时,管口外缘应与井内壁平齐;管径大于300mm时,砌体结构井室应用砖圈加固。

8.2.3砌体结构井室施工应符合下列要求:

1砌筑前,砌块应充分湿润,砌筑砂浆配合比应符合设计要求,现场拌和应均匀,并按要求拌和;

2排水管道检查井的溜槽应与井壁同时砌筑;

三。砌块应垂直铺设,当需要封闭砌体时,应按设计要求设置钢筋混凝土梁;圆竖井采用砌块逐层封闭,四周封闭时每层深度不大于30mm,偏心关闭时每层深度不大于50mm;

4砌筑砌块时,砂浆应饱满,砂浆应与砌块粘结紧密,不得漏浆。上下砌块应错缝砌筑;

5砌筑时应同时安装台阶。台阶安装后,砌筑砂浆未达到规定抗压强度前,不得踩踏;

6内外井壁用水泥砂浆勾缝,如有抹灰要求,应分层夯实。


The concrete foundation of the well chamber shall be poured at the same time as the pipe foundation

The concrete foundation of the well chamber shall be poured at the same time as the pipe foundation, and the construction shall meet the requirements of article 5.2.2 of this code.

8.2.2 the construction of the pipeline passing through the shaft wall shall meet the design requirements; if there are no design requirements, the following requirements shall be met:

1. When the connection between the outer wall of concrete pipe and the hole ring of masonry shaft wall is rigid, the cement mortar should be full and dense;

2. For metal pressure pipeline, casing should be set in the hole ring of shaft wall, and the gap between the outer wall of pipeline and casing should be uniform all around, and the gap should be filled with flexible or semi flexible materials;

3. Intermediate layer method should be used to connect chemical building materials pipeline with shaft lining;

4. For the cast-in-place concrete structure well chamber, the shaft wall hole ring should be vibrated tightly;

5. When the drainage pipe is connected to the inspection well, the outer edge of the pipe orifice shall be flush with the inner wall of the well; when the pipe diameter is more than 300 mm, the masonry structure well chamber shall be reinforced with brick ring.

8.2.3 well chamber construction of masonry structure shall meet the following requirements:

1. Before masonry, the masonry blocks shall be fully wet; the masonry mortar mix proportion shall meet the design requirements, and the on-site mixing shall be uniform and mixed as needed;

2. The chute in the inspection well of drainage pipeline should be built with the shaft wall at the same time;

3. The masonry blocks shall be laid vertically, and when it is necessary to close the masonry, the reinforced concrete beams shall be set according to the design requirements; the masonry blocks shall be used to close the circular shaft layer by layer, and the depth of each layer shall not be more than 30mm when the four sides are closed, and the depth of each layer shall not be more than 50mm when the eccentric is closed;

4. When building blocks, the mortar should be full, and the mortar should be closely bonded with the block without leakage. The upper and lower blocks should be built with staggered joints;

5. Steps shall be installed at the same time during masonry. After the steps are installed, they shall not be trampled before the masonry mortar reaches the specified compressive strength;

6. The internal and external shaft walls shall be pointed with cement mortar; if there is a requirement for plastering, the plastering shall be compacted in layers.


井室的混凝土基础应与管道基础同时浇筑

 

井室的混凝土基础应与管道基础同时浇筑;施工应满足本规范第5.2.2条的规定。

8.2.2  管道穿过井壁的施工应符合设计要求;设计无要求时应符合下列规定:

    1  混凝土类管道、金属类无压管道,其管外壁与砌筑井壁洞圈之间为刚性连接时水泥砂浆应坐浆饱满、密实;

    2  金属类压力管道,井壁洞圈应预设套管,管道外壁与套管的间隙应四周均匀一致,其间隙宜采用柔性或半柔性材料填嵌密实;

    3  化学建材管道宜采用中介层法与井壁洞圈连接;

    4  对于现浇混凝土结构井室,井壁洞圈应振捣密实;

    5  排水管道接入检查井时,管口外缘与井内壁平齐;接入管径大于300mm时,对于砌筑结构井室应砌砖圈加固。

8.2.3  砌筑结构的井室施工应符合下列规定:

    1  砌筑前砌块应充分湿润;砌筑砂浆配合比符合设计要求,现场拌制应拌合均匀、随用随拌;

    2  排水管道检查井内的流槽,宜与井壁同时进行砌筑;

    3  砌块应垂直砌筑,需收口砌筑时,应按设计要求的位置设置钢筋混凝土梁进行收口;圆井采用砌块逐层砌筑收口,四面收口时每层收进不应大于30mm,偏心收口时每层收进不应大于50mm;

    4  砌块砌筑时,铺浆应饱满,灰浆与砌块四周粘结紧密、不得漏浆,上下砌块应错缝砌筑;

    5  砌筑时应同时安装踏步,踏步安装后在砌筑砂浆未达到规定抗压强度前不得踩踏;
