Technical Field

The invention belongs to a construction technical method which relates to a basement top plate structure of a high-rise building, waterproof coiled material and a fine stone concrete protective layer which can survive in one step. More particularly, the construction method relates to a construction method for pouring the fine stone concrete protective layer in time after the concrete reaches the strength of 3-5 days after leveling, compacting and finishing the primary pulp and the concrete is made into a waterproof coiled material and qualified by inspection and acceptance in the process of pouring the concrete of the top plate structure of the basement of the high-rise building.

Background

At present, in the long-term practice of basement construction of high-rise buildings, the habitual method is as follows: and often, after the structure of the basement roof is constructed, earth around the basement foundation pit is backfilled. Directly setting up a steel bar processing and manufacturing field on a basement roof plate structure, planning a template square timber stacking warehouse, laying sand, stone and cement storage yards, installing a mortar stirrer and the like. Meanwhile, the construction of the superstructure of the high-rise building is carried out immediately after the construction, and when the superstructure is constructed to about ten floors, the construction of the brick wall is inserted, and the construction of the secondary structure is carried out. After the high-rise structure is capped, finishing the secondary structure immediately after capping, checking and accepting the structure, and after the structure is qualified, completely spreading the interior and exterior decoration construction of the building. When finishing almost waiting for the decoration, clear away and move all and face the facility again, clear up basement roof structure, carry out roof structure cement mortar and level, compaction, receive the light back, do the waterproof and fine aggregate concrete protective layer of coiled material, backfill earthwork, do outdoor totality. In summary, the following steps: a large number of repeated processes and repeated labor are generated, and huge workload and engineering cost are increased. The construction period is delayed, and great economic loss is caused.

Therefore, only one construction technical method which simplifies the construction process flow and strives for one-step survival is invented, so that the repeated investment and the repeated labor are avoided, the working procedures are reduced, the workload is reduced, the construction period is shortened, the economic benefit is improved, and the engineering construction quality is ensured and improved.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the method aims at the defects and shortcomings of the conventional construction technical method which is directly erected on the basement roof structure and is used for a long time, so that the construction technical method which is adopted for forming the concrete of the basement roof structure, paving and pasting the coiled material in a waterproof way and pouring the fine stone concrete protective layer comprehensively considers the survival in one step, repeated labor investment is avoided, the working procedures are reduced, the workload is reduced, the cost is reduced, the construction period is shortened, the economic benefit is improved, and the engineering construction quality is ensured and improved.

In order to solve the technical problems, the inventor obtains the technical scheme of the invention through practice and summary, and the invention discloses a construction method for forming a roof structure, a waterproof coiled material and a protective layer of a high-rise building basement in one step, which comprises the following steps:

the method comprises the following steps: in the process of pouring concrete of the basement roof structure, after the concrete is vibrated to be compact, primary pulp is leveled, compacted, smoothed and maintained;

step two: when the structural concrete has the strength of 3-5 days, cleaning and drying, brushing the binder, and making the coiled material waterproof;

step three: binding an anti-crack reinforcing mesh on the waterproof layer of the coil material which is qualified after acceptance, and pouring a fine aggregate concrete protective layer after acceptance;

step four: laying and facing the facility greatly, backfilling the earthwork of the open roof area, carrying out superstructure construction, and alternating outdoor overall construction.

Preferably, in the second step, concrete of the top plate structure is poured into one block gradually.

Preferably, in the third step, the waterproof layer of the coiled material is finished one by one, and the fine stone is concreted one by one until the top plate is finished.

Compared with the prior art, the invention can obtain the following technical effects:

1. the invention avoids repeated investment and repeated labor, reduces working procedures, workload and cost, shortens construction period, improves economic benefit, and ensures and improves engineering quality.

2. The invention solves the technical problems in the construction of basement top plate structure, coiled material water-proof and fine stone concrete protective layer of high-rise building in one air survival: the method is a challenge for the traditional method, a construction process technical method is innovated, and the sinking and long construction chain of the conventional construction process technical method is cut off. After the previous process is completed, the next process is implemented following the previous process, the concrete pouring of the top plate structure living in one step is compacted by vibration, primary pulp is leveled, compacted and collected, all construction contents of waterproof paving of the coiled material and pouring of the fine stone concrete protective layer are achieved, continuity between the processes is achieved, repeated investment is avoided, secondary leveling, compaction and collection of the top plate structure are avoided, engineering materials and labor cost are saved, the construction period is shortened, soil is filled in 6-8 months in advance, and the necessary conditions for outdoor overall construction in advance are achieved. Meanwhile, the cost is reduced, and the economic benefit and the construction quality level are improved.

3. The invention utilizes the primary concrete pulp of the basement roof structure to level, compact and collect the light, avoids the procedures of secondary structure surface cleaning and cement mortar leveling, compacting and collecting the light, and simultaneously, a coiled material waterproof layer and a fine stone concrete protective layer are manufactured immediately after the procedures. The construction period chain is compressed, the repeated investment is avoided, the workload is reduced, the cost is reduced, the engineering quality level is improved, and good economic benefit and social benefit are obtained.
