Preparation for the first level constructor exam high frequency test center formula

Formula] Ann Da water cave storage sake.

Construction Machinery Usage Fee:

Depreciation + overhaul + regular repair + demolition fee and off-site freight + labor + fuel power + tax.

Exam 100, a lot of test center memory.

Formula: Complete +4 types of information, pay attention to each item, main one, and respectively.

Interpretation of the formula: completion and acceptance of construction projects.

It should be qualified.

1) Complete the construction project design and the contents agreed in the contract;

2) Have complete technical files and construction management materials;

3) There is an approach test report of the main building materials, building accessories and equipment used in the project;

4) There are quality qualification documents signed by survey, design, construction, engineering supervision and other units;

5) There is a project warranty signed by the construction unit.

Shorthand: mechanical foundation pit hydropower pile.

Briefly describe the main contents of safety control of foundation engineering construction.

Answer: (1) the safety of excavation machinery;

2) Slope and foundation pit support.

Safe; 3) Precipitation facilities and temporary electricity consumption.

Safe; 4) Fire prevention and anti-virus safety during waterproof construction;

5) Safety precautions for pile foundation construction.

Formula: Bullet base structure.

Construction precamber considerations for formwork, brackets, and arches.

Formwork, brackets and arches should be designed with pre-cambering. The following factors should be considered for construction precamber:

1) The precamber of the structure specified in the design documents;

2) elastic deformation caused by the bracket and the arch bearing all the construction loads;

3) Inelastic deformation due to the compression of the extrusion and unloading equipment at the rod joint after loading;

4) Settlement of brackets and arch foundations after loading.

Formula] high and low, high and small, choose large (deviation control of equipment installation accuracy) steam turbine and dryer operation to compensate for the deviation caused by temperature changes:

When adjusting the radial displacement of the two axes, the end with high temperature during operation (steam turbine, dryer) should be lower than the end with low temperature (generator, blower, motor).

When adjusting the tilt of the two axes, the upper clearance is less than the lower clearance.

When adjusting the gap between the two end faces, a large value is selected to compensate for the deviation caused by the temperature change during operation.

Formula: five up and six down, seven and a half hundred horizontally.

The uphill longitudinal slope is greater than 5%, the downhill longitudinal slope is greater than 6%, the plane radius is less than 50m or the super-high cross slope is more than 7%, and the sliding form should not be used.

Pavers are used for paving.

Shorthand formula: three-two-one-six.

Blast the sound signal.

1) The sound signal of open cut blasting is specified as follows:

Warning signal: three long sounds (30s) intermittently, at this time, the site stops working, and the personnel quickly evacuate.

Preparation signal: one long (20s) and one short (10s) three times intermittently.

Detonation signal: three short tones in a row (10s).

Discharge signal: one long sound (60s); After the inspector confirms the safety, the person in charge of the blasting operation notifies the alarm room to send a release signal.

The mantra of the first construction practice is as follows:

1. The whole life cycle of a construction project includes the decision-making stage, implementation stage and use stage (or operation stage, or operation stage) of the project.

Mantra: Hunger strike to death.

2. There is no unified model for the decomposition of the project structure, but it should be carried out in combination with the characteristics of the project and with reference to the following principles.

1) The overall deployment that takes into account the progress of the project.

2) Consider the composition of the project.

3) It is conducive to the awarding of project implementation tasks (design, construction and material procurement) and the pre-implementation of the project, and is combined with the contract structure.

4) It is conducive to the control of project objectives.

5) Organizational structure combined with project management, etc.

Formula: Two considerations, two combinations, three beneficial.

3. Construction organization design is an important means of scientific management of construction activities, which has the dual role of strategic deployment and tactical arrangement. Basics:

1) Project overview.

2) Construction deployment and construction plan - reasonable arrangement of the construction sequence, determine the construction plan of the main project.

3) Construction schedule – reflects the timing of the best construction plan.

4) Construction plan - is the comprehensive arrangement of the construction plan and construction schedule in space. So that the whole site can be organized to carry out civilized construction.

5) Main technical and economic indicators.

Formula: Cadres love to draw charts.
