Description

Outer wall of underground structure HCMW engineering method composite walls
Technical field
Technical field of building construction is the utility model is related to, it is compound more particularly to a kind of outer wall of underground structure HCMW engineering methods Wall.
Background technology
Traditional outer wall of underground structure working procedure:Supporting, excavation (increasing fertile groove), bed course, waterproof slab, colligation Bottom Board Steel Muscle and reinforcing steel bars of wallboards, pour underplate concrete, edge-on mould inside and outside colligation exterior wall and post reinforcing bar, outer wall of underground structure, pour exterior wall Concrete, external wall waterproof coiled material are pasted, waterproofing protection, fertile groove backfill, outdoor pipeline is buried, floor construction, in work progress Following problem generally existing:
1st, exterior wall shuttering constructional difficulties
Excavation of foundation pit space is limited, and typically reserved construction space fertilizer well width is less than 1.2 meters, outside narrow space underground structure Wall form difficulty of construction is big, and the working environment of workers is poor, and job scheduling is slow, and scaffold is torn open take twice, and turnover wastes serious;
2nd, fertile groove backfill difficulty densification is real
Space is excessively narrow and small between exterior wall and supporting construction, and waterproof roll needs to protect, and backfill is unable to mechanized construction, Quality is difficult to control.Feed back is loose, is often mixed into the debris such as fragment of brick, batten, rubbish, or even backfill with water.Posterior settlement continues Time is grown, and settling amount is big, causes the facilities such as water pipe leak, pipeline damage, aproll decoration to destroy;
3rd, backfill is loose, the retaining basin artificially manufactured
Backfill is loose around outer wall of underground structure, has artificially manufactured a retaining basin, and underground structure is just seated in water storage In basin, rain ponding, pipe leakage ponding are collected in foundation ditch fertilizer groove, because excavation slope safeguard procedures stop that ponding is lost in, Water level is higher than ordinary water level in the soil body of periphery in retaining basin.Water buoyancy exceedes design anti-floating standard.This is on many underground structures The main reason for floating.If local coiled material damages leak, then whole waterproof coiled material system slowly fails;
4th, supporting construction system is scrapped after foundation ditch backfill, and waste seriously forms obstacle simultaneously and is permanently present.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of outer wall of underground structure HCMW engineering method composite walls, structure Advantages of simple, cancel fertile groove, so as to avoid the series of malpractice of fertile groove, water resistance enhancing, process is simplified, easy for construction, contracting Casual labourer's phase.
In order to solve the above technical problems, the technical scheme that the utility model uses is:There is provided outside a kind of underground structure Wall HCMW engineering method composite walls, including:
Soil-cement piling wall, the Soil-cement piling wall include multiple cement mixing methods being continuously mutually twisted, It is spaced in the multiple cement mixing method or is continuously inserted with precast reinforced concrete piles;
Screed-coat, it is arranged on the inwall of Soil-cement piling wall;
Outer wall of underground structure, the outer wall of underground structure are arranged on the inwall of screed-coat, the outer wall of underground structure bag Include reinforcing bar and the concrete mixed with waterproof compacting agent.
In one preferred embodiment of the utility model, the cross section of the precast reinforced concrete piles is in dumbbell shape.
In one preferred embodiment of the utility model, waterproof mortar course is provided with the inwall of the screed-coat, it is described Outer wall of underground structure is arranged on the inwall of waterproof mortar course.
In one preferred embodiment of the utility model, the thickness of the waterproof mortar course is 25 ~ 30mm.
The utility model has the advantages that:
1st, Soil-cement piling wall and water-proof concrete wall are cement base inorganic material, buried underground and soil using material Earth contacts, and particularly soil cement is grown in underground chemical reaction perdurabgility, and intensity, crystalline solid constantly increase, with underground structure wall Main body concrete structure is gradually fused into one;
2nd, water resistance significantly increases, and the impervious coefficient of Soil-cement piling wall itself has waterproof action in 10-8cm/s;Water Soil churned pile wall is combined closely with underground structure concrete exterior wall, is eliminated and is excavated fertile groove, has cut off permeable path, permeates road Footpath extends, and infiltration hydraulic pressure is substantially reduced;In Soil-cement piling wall, cement soil wall is continuous, from soil, soil cement, concrete Wall rigidity is gradual change, smaller to concrete walls deformation constraint, and soil cement is impervious strong in itself, plasticity is big, it is permeable to be not easy to be formed Crack, every prefabricated pile independently bear external force, are wrapped in cement soil wall, bear the impermeability that external force has no effect on soil cement Energy;
3rd, difficulty of construction is reduced, only need to be in inner side one side shuttering, process using Soil-cement piling wall as outboard template Simply, by being implanted into split bolt on prefabricated pile, unilateral shuttering operation is easy, easily simple;Cement mixing method is gone along with sb. to guard him Wall, substantially plane, simple linked network mortar powder are put down, you can do rigid composite waterproof layer;Whole flow process is simple, working face is open, Worker's construction environment improves;
4th, the duration shortens, and process simplifies, and coiled material construction, backfilling of earthwork, outside scaffold template construction is eliminated, by day The influence of the external factors such as gas, space is small, and construction joint quantity reduces, and the duration substantially shortens;
5th, cost savings, for turnover using reducing, outside shuttering is required more with quantity such as short and small steel pipe, fasteners, wastes Seriously, all eliminate;Process simplifies, and construction joint quantity is reduced, and cost of labor reduces;Backfill cost savings;Construction land tenure Reduce, can amplify using space, development & construction resource is exaggerated.
