Masonry process for inspection wells

材料：砖、中砂、水泥

Material: brick, medium sand, cement

机具：砂浆搅拌机、模具、灰杆

Machine tools: mortar mixer, mold, ash bar

应用范围：排水、专业管线工程的砖砌圆形检查井。

Application: Brick circular inspection wells for drainage and professional pipeline engineering.

过程陈述：

Process statement:

1. 定位井室中心，根据管道外径和井室半径（内径）计算检查井中心至管口间距,管道安装时预留。

1. locate the center of the well, calculate the distance between the center of the well and the distance between the pipes according to the outer diameter of the pipe and the radius of the well chamber.

计算管间距:H=

Computing tube spacing: H=

H—检查井圆心到管口距离

H - check the distance between the center of the well and the pipe

R—检查井内半径

R - check the radius of the well

D—管材外侧直径

D - tube lateral diameter

2.钢筋砼基础，井定位、放样，摆砖预铺，调整灰缝，做到满铺满挤。

2. reinforced concrete foundation, well positioning, lofting, brick pre laying, adjust the seam, so that it is full of crowded.

3.流槽与井壁同时砌筑，用刮杆法控制流槽砌筑尺寸（预留抹面厚度），按图集要求设置脚窝。

The 3. is the simultaneous construction of the channel and the shaft lining. The scraper bar method is used to control the size of the chute (the thickness of the reserved plaster), and the foot nest is set according to the atlas.

4.干管、支管均砌砖券，井室砌筑采用模具法控制。

4. the dry pipe and branch pipe are all built brick vouchers, and the well chamber masonry is controlled by the mold method.

注：发券垂直管壁，对应管道直径方向。

Note: voucher vertical pipe wall corresponds to pipe diameter direction.

5.踏步和脚窝位置提前计算，检查井砌筑同步安装、留置，位置准确，尺寸规范，安装牢固。

5. step ahead and foot nest position calculation, check well masonry synchronous installation and retention, accurate location, size specification, solid installation.

6.流槽抹面灰杆法控制圆顺度。

The 6. channel plastering grey rod method is used to control the roundness.

7.采用模具抹面，刮杆找平控制平整度。

7. use mold plaster, scraper leveling control flatness.

8.硬化场地，制作定型模具，集中场地预制检查井盖板。

8. hardening site, making stereotyped mold, concentrating the site to prefabricate the well cover plate.

9.座浆安装盖板（人孔与井室、井口位置应吻合），抹三角灰稳固，砌筑井口高度符合道路结构层施工要求（可考虑采用预制拼装）。

9. slurry installation cover plate (manhole and well room, wellhead position should be consistent), smear triangle solid, masonry height of the wellhead is in line with the construction requirements of the road structure (consider the use of prefabricated assembly).

控制要点：管口预留间距，流槽尺寸，踏步间距，盖板安装，抹面，养护。

Main points of control: the distance between pipe outlets, the size of the chute, the distance between steps, the installation of the cover, the plastering, and the maintenance.

质量要求：检查井各部位尺寸准确，井室、井筒抹面光滑平整，流槽顺直、圆滑，踏步（脚窝）位置准确，盖板安装稳固。

Quality requirements: the accuracy of each part of the inspection well, the smooth and smooth surface of the well and the wellbore, straight and smooth slots, the accurate position of the foot step (foot nest), and the stable installation of the cover plate.

安全文明要求：

Safety and civilization requirements:

1.材料堆放、覆盖符合施工规范要求。

1. material stacking and covering conform to the requirements of the construction specification.

2.基坑、井内操作时，施工人员必须佩戴安全帽，并有旁站人员监控。

2. during the operation of foundation pit and well, the construction personnel must wear helmet and monitor by the side station.

3.基坑、井口安全防护到位。

3. the safety protection of the foundation pit and the wellhead is in place.

4.检查井口施工后应及时安装井盖，或采用钢板、砼盖板覆盖、防护。

4. after the construction of the inspection wellhead, the manhole cover should be installed in time, or the steel plate and concrete cover should be used to cover and protect it.
