After going to work the next morning, the trench inspection work went smoothly. Engineers from the geological survey and design unit put on rain boots and went down to the foundation pit to inspect them one by one. In the end, they just said: "After cleaning the mud in the foundation pit, you can proceed to the next process."
Zeng Yiming did not dare to neglect and asked the master workers to quickly prepare a small water pump and wash away the muddy water at the bottom of the foundation trench in front of them.
Fortunately, when digging the foundation pit, Zeng Yiming had a backup plan and had several large pits dug. These pits were enough for the muddy water to flow into it, and then it could be scooped out manually into the sand and pebbles nearby, which was very convenient. Fast.
Why didn't he rinse it off earlier? He was here to inspect his work, so he always had to leave some insignificant problems for others to pick out, right? Do you think everything is perfect? In fact, there may be more problems waiting for you to rectify.
After the relevant personnel sign and confirm the documents, the master workers must complete the erection of the formwork and brackets in the morning before pouring the foundation layer on time in the afternoon.
Strictly speaking, there should be a cushion layer, because there are no steel bars in the foundation, so the designer simply omitted this layer when drawing the drawings. It was not that Zeng Yiming wanted to cut corners.
Zeng Yiming waved to the labor team leader of the frame workers and carpenters. After seeing the two people coming to him, he calmly said to Lao He, the carpenter team leader: "There is only one copy of the drawing. You follow this The basic template will be made according to the dimensions, and I will check it before going to work at noon."
After explaining the business, he still had one small thing that needed to be completed by the carpenter. He took out a white picture. This was the chute he drew with a pencil in the office, and he needed the carpenter to help him process it.
"Follow this diagram and use wood boards to nail it out for me. See if the keel is intact. Make sure it is firm. If it falls apart, I will cause trouble for you."
The so-called chute is a wooden trough that transports concrete in a vertical direction. Its purpose is to prevent the stones and mortar in the concrete from separating - this is called segregation and will not play its intended role.
The height of this retaining wall is close to ten meters, so currently we can only rely on chutes to transfer concrete to the bottom of the foundation, and two sections are needed to connect it.
Lao He showed his big teeth and said with a simple smile: "I have made chutes several times, and they are used on many housing construction sites."
When Zeng Yiming learned that he had processed it before, he stopped worrying and just nodded.
Zeng Yiming turned to Lao Wang, the erection team leader, and said: "In addition to fixing the formwork, the scaffolding also has to bear the weight of the concrete itself transmitted from the formwork and the force transmitted during the vibration process.
After my calculations, the spacing between their poles is set at 50cm, with horizontal crossbars at the top and bottom, and vertical tie rods at the top. "
Lao Wang was silent and just hummed in his nose.
Zeng Yiming once again emphasized the progress requirements and safety issues, then waved to them and let them go about their business.
After Zeng Yiming made arrangements there, he went to the material yard without stopping. He wanted to ensure that the quantity of sand and gravel raw materials should at least meet today's use. Don't run out of material halfway through pouring, which would be very embarrassing.
As a local snake, Scar is very reliable in supplying raw materials. It is said that these materials come from his boss, Qin Si in the south of the city. Zeng Yiming has no interest in Qin Si for the time being.
Zeng Yiming saw that Lao Zhang, the head of the masonry team, was holding a meeting with the masons. He waved to him, took out the mix ratio he had calculated, handed it to him and said, "Strictly follow this mix ratio. Cubic concrete can only use 340kg of cement, 1250kg of gravel, 620kg of sand and 175kg of water.”
Seeing the latter nodding, he walked to the scale alone and continued: "When you were not sure how to grasp it a few times in the past, you asked the master workers to weigh it here. After weighing it a few times and getting familiar with it, it will naturally become easier. Don’t be too troublesome.”
Lao Zhang nodded and made a metaphor in his unique rough voice: "I know, this is just like eating food supplies in previous years. It is a fixed plan and will not be changed at will."
Zeng Yiming heard that his metaphor was appropriate and couldn't help but agree: "There is nothing wrong with saying that. If these materials are not enough, you must tell me half a day in advance. It may be busy these days!"
After Zeng Yiming finished speaking, he pointed to the flakes next to him and whispered: "See the pile of flakes covered with colorful strips of cloth. When the foundation is poured later, find a way to add 30% to the concrete."
Lao Zhang blushed and nodded hurriedly.
In fact, adding an appropriate amount of gravel to the plain concrete foundation can help improve its compressive strength and save costs. It’s just that there were no design requirements in this project, and Zeng Yiming wanted to take advantage of it and take advantage.
This is also related to the stress of the structure. The gravity retaining wall only bears the pressure from the upper part and the shear force of the soil on the side is very small. If it is a structure mainly based on shear force, Xiao Ming will not give it a hundred courages. Dare to add randomly.
Zeng Yiming clearly knew that there was still an impression of a book in his mind called "Soil Mechanics Foundation", which explained the classification and mechanical properties of retaining walls in great detail.
According to the description in the book, the gravity retaining wall he is building now is the simplest of all retaining walls.
As for the 30% content he required, it is the limit value in concrete. After all, it is not a mortar or concrete masonry retaining wall. You still have to have a bottom line.
"Lao Zhang, we're going to pour water in the afternoon. Check the drum mixer, the vibrator used for vibration, etc., and feed it with butter. The person who drives the mixer, let him familiarize himself with the operating procedures. Safety is the top priority!”
After Zeng Yiming finished explaining the things here, there was nothing going on at the scene for the time being. He walked back to the office and guided Chengzi to fill in the project information.
There is a proverb circulating in the engineering industry: Well done is not as good as well spoken, and good speaking is not as good as well written. This well-written actually refers to engineering data.
It can be seen that data is also an extremely important task, and it is divided into three major parts: technical data, economic data, and safety data.
These tasks should have been completed by three people. Who said that Zeng Yiming is now the bare commander? He can only pull Cheng Zi to temporarily take over.
In addition to taking the blame, my good friend also has to do the hard work within his ability. After writing these three pieces of information, as well as the construction diary for the past few days, I can only let him write it.
If Zeng Yiming remembers it correctly, in about one or two years, a guide will be released. At that time, just throw the big guy in front of Chengzi, and just follow it and write it.
Zeng Yiming is not idle either. He still needs to do a lot, such as earthwork, scaffolding, formwork, and special construction plans for concrete pouring. These can only be completed by him.
Even with the Internet, he couldn't find these now. He suddenly missed the Internet era when everything was available. Now, he could only work hard, write it by himself, and then revise it after writing.
