Steel structure prefabricated houses are currently widely used temporary housing buildings. Although the main skeleton of the prefabricated house is steel structure, its foundation is not. Most foundations are concrete structures, and steel structure prefabricated houses have certain requirements for the hardness of the foundation. The hardness of the foundation determines whether special treatment is necessary, and laying a good foundation is crucial for the project.

1.要進行硬度測試，特殊的地形和地基的硬度對建造活動房來說有較大的差別，應當作特殊的處理，保證鋼結構活動板房可以順利安裝，確保其質量，技術人員應該提前進行測量。

Firstly, hardness testing should be conducted. Special terrain and foundation hardness have significant differences for the construction of prefabricated houses, and special measures should be taken to ensure the smooth installation of steel structure prefabricated houses and their quality. Technical personnel should conduct measurements in advance.

2.完成了地基的測量后，接下來就是基礎澆筑，這時的在于必須先測量好水平，在完成了澆筑后，應該控制水平的誤差在10mm內。必須要保證基礎面水平在誤差以內，這樣才不會影響后續的工作進程。

After completing the measurement of the foundation, the next step is foundation pouring. At this point, the key is to measure the level first. After completing the pouring, the horizontal error should be controlled within 10mm. It is necessary to ensure that the level of the foundation surface is within the error range, so as not to affect the subsequent work process.

3.混凝土標號，一般情況下基礎為c20且內無鋼筋，當然，在特殊的地形或者其他不可抗拒的條件下，應當根據技術人員的測定來頂下終方案。

3. Concrete grade, usually based on c20 and without steel bars inside. However, in special terrain or other irresistible conditions, the final plan should be determined based on the determination of technical personnel.

4.澆注時間，跟常規的混凝土澆筑工藝一樣，鋼結構活動板房同樣不可以減少工藝程序，基礎澆筑完成后或者活動板房安裝之前應該留充分的時間讓混凝土達到硬度要求。

4. Pouring time: Like conventional concrete pouring processes, steel structure prefabricated houses cannot reduce the process procedures. After the foundation pouring is completed or before the installation of the prefabricated house, sufficient time should be left to ensure that the concrete meets the hardness requirements.

5.后的澆筑，制作基礎的同時，必須跟室內地面一起澆筑完成，水平高度跟基礎一樣，這樣可以確保安裝工期、質量以及安裝后的美觀。活動板房安裝好了以后，在室內鋪地板，這樣既方便又整潔。

5. The subsequent pouring, while making the foundation, must be completed together with the indoor ground, with the same horizontal height as the foundation, to ensure the installation period, quality, and aesthetics after installation. After the installation of the prefabricated house, the floor should be laid indoors, which is both convenient and tidy.

另外，室內地板的水平高度應該比基礎水平高出50mm,保證雨水不會流入室內以及保證地圈梁的牢固程度。

In addition, the horizontal height of the indoor floor should be 50mm higher than the basic level to ensure that rainwater does not flow into the room and to ensure the firmness of the ground ring beam.
