1. Foundation pit leveling method in order to ensure the accuracy requirements of building height control, we should pay attention to accurately measure the elevation in the foundation construction. by ± The elevation above 0.00 shall be transferred to lay a good foundation. When the elevation of the site benchmark is measured into the basement foundation pit, a horizontal line of the whole meter can be drawn on the retaining piles around the foundation pit, which can be used as the basis for the elevation measurement of the basement. The elevation control line should be drawn according to the construction needs. For each elevation line, it should be calibrated. When the error is large (& gt; 5 mm) should be adjusted

2. Steps of foundation pit leveling

(1) an elevation coordinate network should be built in the foundation pit to control the flatness of the whole foundation pit through the elevation coordinate network, which is generally 4m * 4m

(2) foundation construction survey: including pile foundation construction survey, leveling and setting out of foundation trench excavation, foundation setting out ± Leveling and setting out below 0.000 elevation

(3) elevation control ring earthwork excavation: ring earthwork excavation, a special person shall be responsible for the determination of elevation, and the method of excavation and measurement shall be adopted. When approaching the base, the elevation point should be led into the foundation pit, and the mark can be made on the reinforcement of the engineering pile. It can be used as the basis for the cushion pouring and supporting the bottom plate formwork in the bottom plate construction stage

3. Using instruments and equipment:

there are mainly two kinds of instruments for setting out, theodolite and level. The advanced ones change the theodolite into full occupation meter, including positioning with full occupation meter, measuring the detailed construction dimensions of each part of the building according to the drawings, and the workers construct according to the given line

4. Step - the procere and order of things
method the method and form of words and deeds
method: the way, step and means to achieve a certain purpose

in the three words, the meaning of method and manner are basically the same, but the way is more formal and is generally used in written language; The method is popular, spoken and written language can be used. As for the step, it is far from the meaning of the above two words and emphasizes a sequence

let's take a simple example. When you make fish, you first heat the pan, then add oil, then fry the fish, and then add seasonings. This sequence is called steps. For the same fish, you can steamed, braised or stewed, which is called method or method.

5. Generating files is the steps of file pre-processing, file combination, material arrangement, binding, cover cataloging, etc
supplement:
a file is a file storage unit which is composed of several interrelated documents and put into the file folder and the file cover. It is also the basic unit for the arrangement, cataloging and statistics of the whole file system. File is based on the source of the document, time, content and appearance of the similarities and differences and contact, including the cover of the file, the file directory, the file, the reference form and other parts

6. Steps: the accounting firm shall write a confirmation letter to the Bank of the auditee, submit it to the Bank of the auditee for signature and confirmation, and then the accounting firm shall deliver it to the Bank of the auditee. The bank shall also send the statement sent back to the accounting firm directly. Methods: 1. In the process of letter confirmation of bank deposits, loans and other important information with financial institutions, certified public accountants should understand the actual bank deposit balance, loan balance and mortgage, pledge and guarantee situation of the auditee. 2. Letter confirmation of zero balance accounts and accounts cancelled in the current period, In order to prevent the audited unit from concealing bank deposits or loans

7. In fact, it's very simple to a lot of key knowledge from the book according to your specific major combined with the current learning environment. Plus your learning experience, you don't need to write how much wonderful it is, just be more real. Come on ~ ~ ~ in fact, you won't check it when you hand it in
