Description
Technical field
The invention belongs to building foundation engineering construction fields, and in particular to a kind of basement gear based on brick fetal membrane moulding wall
Wall construction method.
Background technique
With the development of economy with the sustainable growth of population, land resource increasingly seems urgent.University is promoted from religion
Educating land used is commercialized land used transition to half Educational Return land used half, therewith it is adjoint be a large amount of comprehensive commercial mansion such as rain after
It has emitted and has come out as spring bamboo.But commercial mansion will not only meet the land for teaching requirement of school, and meet business
The benefit requirement of profit, so commercial mansion addressing generally can all be selected in close city road side, to largely increase
The difficulty of construction, and Deep Foundation Pit construction is more intended to excavate without fertile slot.
Building foundation pit refers to that the outer foundation pit inner wall of building basement exterior wall does not scrape out slope without fertile slot excavation construction method,
And state in a vertical shape, so that the operating space of outer wall of basement and foundation pit crater wall is than narrow building foundation pit construction method.
Traditional basement barricade waterproof construction first realizes basement barricade（That is outer wall of basement）Formwork pours, and waits gear
After wall maintenance molding, asphalt water-proof coiled material is pasted on the outside of barricade, then a protective layer is set again, construction foundation working is complete
It is backfilled again after finishing, completes entire construction.But basement barricade and foundation pit supporting system distance caused by thus being excavated without fertile slot
Cross close, it is more difficult that barricade outboard template installs, and waterproof coiled material construction no operatton face is difficult to construct, and institute is so as to the construction that needs one kind new
Technique solves problems.
To solve the above-mentioned problems, applicant considers that devise a kind of elder generation is arranged moulding wall in basement foundation ditch crater wall,
Then it relies on moulding wall to be first arranged again to pour the mode of barricade after waterproof layer again and complete barricade waterproof construction, improves waterproof construction
Convenience and reliability.But wherein how the construction technology is specifically arranged, in the construction for facilitating moulding wall, preferably raising waterproof
The convenience and reliability of construction become and need further to be considered the problems of to solve.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：How a kind of construction letter is provided
Single, short time limit, expense is low, the basement Retaining wall method based on brick fetal membrane moulding wall of good water-proof effect, is particularly suitable for base
It cheats and is practiced in the construction foundation working of deeper skyscraper.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
First moulding is arranged in basement foundation ditch crater wall in a kind of basement Retaining wall method based on brick fetal membrane moulding wall
Wall, moulding wall outer surface and basement barricade outer surface design shape correspond to it is consistent, then moulding wall outer surface carry out
Waterproof coiled material construction obtains barricade waterproof layer, forms basement barricade outside-supporting by moulding wall and barricade waterproof layer, carries out
Single side formwork on the inside of the binding of basement barricade reinforcing bar and barricade is completed basement barricade and is poured.It is characterized in that, basement foundation ditch
Moulding wall is set in crater wall using the method for setting brick fetal membrane after-pouring moulding concrete, specifically includes following steps：
1）Support pile is buried elevationally outward in foundation pit crater wall in advance；
2）Surveying setting-out determines the welding screw rod setting position of brick fetal membrane setting position and bar planting；
3）Bar planting, the soil layer plane by support pile in face of foundation pit side are opened, drill, will weld on the side surface that support pile exposes
It connects in the vertical implant holes in screw rod inner end and is welded and fixed, the horizontal face support pile in its outer end is made to extend outwardly fixation；
4）Use standard brick masonry brick wall in brick fetal membrane setting position, when building in brick wall along wall length direction at interval of
4.5-4.8 meters pour one of vertical constructional column of setting, pour one layer of collar tie beam of setting along high every 4 meters of wall, constructional column and collar tie beam enclose
At region in build standard brick；The outer end of welding screw rod is poured fixed in collar tie beam or constructional column；
5）Complete brick wall while, after completing one section of height of wall brick, i.e., the casting concrete in brick wall, wall brick build with
Inner concrete pours interval and carries out, until ultimately forming moulding wall wall base；
6）, smear cement mortar outside moulding wall wall base and cover smooth, waterproof coiled material construction can be carried out.
In this way, first realizing that waterproof coiled material construction obtains barricade waterproof in moulding wall outer surface using after setting moulding wall
Layer, barricade waterproof layer are generally obtained by waterproof roll layer and mortar levelling layer, then rely on moulding wall and barricade waterproof layer again, directly
