In case of any new situation or any change in the number of casualties within 30 days from the date of the accident, a timely supplementary report shall be made
.
The earthwork filling thickness and compaction times shall be determined by test according to the soil quality, compaction coefficient and the machines and tools used
.
Correct method: evenly distributed on the main reinforcement of the same section
.
Second, it was found that the waterproof rubber cable at the root of the pump body was aging, and a joint was broken, so it continued to be used after reconnection
.
Correct practice: the number of pieces in each group shall not be less than 3
.
The person in charge of the construction unit shall analyze the cause of the accident and report it to the Construction Department of the county people’s Government where the accident occurred at 4:08 p.m

Xiao Zhang’s learning is a step-by-step process, especially for the more difficult level 2 constructor examination, there is absolutely no way for him to pass the second constructor examination with the learning attitude of fishing for three days and drying the net for two days! In order to help you consolidate the practice regularly, Xiao Zhang brought you the first week’s weekly survey of the second construction case, let’s see how you learn ~ background information of the second construction case, a new commercial and residential building project, reinforced concrete frame shear wall structure, 1 floor underground, 16 floors above the ground, with a construction area of 28000 square meters, and the foundation pile is slurry wall bored pile
.
Reason: after the accident, the relevant personnel at the scene of the accident should immediately report to the construction unit After receiving the report, the person in charge of the construction unit shall report to the competent construction department and relevant departments of the people’s government at or above the county level in the place where the accident occurred within one hour
.
The first correct way: pumping operators should put the submersible pump into the water vertically
.
Write out three factors comprehensively considered in the fabrication and installation of reinforcement cage of cast-in-place pile
.
Whether the reserved settlement of earthwork backfill is correct and the reasons are given? What cleaning contents and related work are there besides the base garbage before earthwork backfill? 3
.

.
This paper points out and corrects the errors in the number and position of the protective cushion blocks of the reinforcement cage
.
Before the construction of backfill, the project department arranged personnel to prepare a special scheme for backfill, including: strictly controlling the particle size and moisture content of backfill earthwork according to the design and specifications, requiring the removal of garbage and other debris from the base before the backfill, and reserving the settlement amount according to 5% of the height of the backfill
.
(1) the accident report time of the person in charge of the construction unit is incorrect
.
For a construction project under general contract, the general contractor shall be responsible for reporting accidents
.
(2) Before earthwork backfilling, the garbage, tree roots and other debris on the base shall be removed, the accumulated water shall be removed, the silt shall be excavated, and the base elevation shall be checked and accepted
.
It continued to use after reconnecting
.
About China Construction Industry Press, since the 2004 registered constructor qualification examination, China Construction Industry Press has been the publishing unit of “examination outline” and “examination book”
.
Question 1
.
(2) Error 1: 2 pieces per group
.
Correct method 2: if the waterproof rubber cable at the root of the pump body is found to be aging and a joint is broken, the submersible pump should be replaced or the waterproof layer should be reprocessed in time and its waterproof performance should be inspected
.
The settlement of the fill shall be reserved according to the design requirements, generally no more than 3% of the fill height
.
Mistake 1: in the process of using submersible pump on site, the pumping operator tilted the submersible pump into the water
.
3
.
Write down the mistakes of on-site pumping operators and correct them
.
China Construction Industry Press has a wide reputation in the field of constructor examination, and has a high degree of recognition in the group of constructors
.
The thickness of each layer of the fill in winter shall be reduced by 20% – 25% compared with the normal temperature construction, and the reserved settlement shall be increased appropriately compared with the normal temperature construction
.
(1) incorrect
.
The second mistake: the cushion block can be distributed freely
.
At 1:15 p.m., the pumping operator found that the submersible pump body had fallen into the sludge and got an electric shock when pulling out the water pipe
.
It has accumulated mature experience in content production, technology development and operation services, and has created an excellent brand of “professional and efficient” in the minds of the majority of candidates
.
Since 2012, China Construction Industry Press has started to provide knowledge services for the candidates of construction engineers through the network platform, serving more than one million candidates
.
After the project department entered the site, at the operation disclosure meeting of reinforcement cage of slurry wall protection cast-in-place pile, it emphasized the matters needing attention in the fabrication of reinforcement cage and cushion block of reinforcement cage protective layer, and required that the reinforcement cage should be fabricated in sections, and the section length should comprehensively consider the three factors of cage formation
.
Xiao Zhang’s weekly survey of second construction this week, how are you doing? If you want to challenge more second construction exercises, you must pay close attention to the second level constructor of construction engineering society
.
It can be put into use only after it is confirmed that it is intact
.
according to the principle that the accident report should be timely and should not be delayed
.
In the process of using submersible pump to pump water, when the pumping operator tilted the submersible pump into the water, it was found that the waterproof rubber cable at the root of the pump body was aging, and there was a joint fracture
.
Is the time of accident report correct and the reasons given by the person in charge of the construction unit? What are the principles of accident report except timely and no delay? Reference answer: 1
.
(2) The principle of accident report should also include accuracy and completeness, and no unit or individual shall fail to report, falsely report or conceal the accident
.
2
.
After rescue, he died
.
There are no less than two groups of steel bar protective layer cushion blocks for each section of steel bar cage, and one group is set in the middle of the cage whose length is more than 12M, with 2 blocks in each group, and the cushion blocks can be freely distributed
.
(1) the reinforcement cage should be made in sections, and the section length should be considered as the overall stiffness of the cage, the material length and the effective height of the lifting equipment
.
