Abstract
The present invention relates to a masonry construction method of the wall modules of a concrete shaft wall. The method includes eight steps: (1) the excavation of earth: according to location dimension, the excavation of earth is carried out; (2) the casting of foundation cushion concrete: according to positioning sidelines and an elevation, the foundation cushion concrete is casted; (3) the casting of foundation mat concrete; (4) the masonry of the wall modules: according to the sizes of the arranged blocks, the wall modules are piled up and the masonry matches holes, so that upper-lower and left-right tongue-and-grooves are aligned with one another; (5) the infusion of concrete: the concrete is compacted by a vibrating rod or a steel reinforcement; (6) the installation of precast lintels and cover slabs: slab joints are caulked; (7) the masonry of an inspection well; (8) the backfilling of earth: unbackfilled trenches around the wall body are backfilled at the same time. Because the present invention applies the construction method of compacting the infused mortar, the effect of compaction is ensured, thus enhancing the anti-shearing property of the wall body. Moreover, because the requirements on construction are restrict, the built wall body is firm and is not easily loosened, thus preventing the phenomenon of leakage. The present invention reduces the waterproof working procedures of the wall body, thus shortening the construction period and reducing the cost.
Description
Technical field
The present invention relates to a kind of construction techniques, specifically relate to a kind of gas column job practices of concrete shaft wall module of the emboss pit with mutual chain lock.Belong to construction engineering technical field.
Background technology
Any building building all must have supporting infrastructure, as: all kinds of manholes, inlet for stom water, box drain, septic tank and the small-sized structure etc. of draining, water storage facility.Building these infrastructure in the past by laying bricks or stones, all is brick mix structure, because parallel seams, impervious weak effect are adopted in the city; In addition, brick mix structure needs great amount of water resources, and mud contamination is arranged, and pollutes big; After building wall is good, also will smear waterproofing course on external and internal wall, also lose time when increasing cost, work efficiency is slow.
Also have now and adopt special-purpose well wall body module when constructing at the scene, used well wall body module has the emboss pit that cooperatively interacts at four sides up and down, blocks mutually when building by laying bricks or stones, is in the milk in intermediate void then, tamping.But because the intermediate portion is except the hole that wears reinforcing bar, UNICOM not each other, in the tamping of being in the milk, cause hole or hollowing easily, make overall structure firm inadequately, and also make waterproof, leakage performance bad, need carry out waterproofing work again in the inside and outside of body of wall, cause the duration longer, increase cost.And shear behavior is also not satisfactory, also causes taking place the seepage phenomenon easily.And, when construction, also need cement mortar, when increasing cost, also environment is caused very big pollution, unfavorable to civilized construction.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide and a kind ofly can effectively prevent seepage, improve shear behavior, do not need to do again waterproofing work, and greatly the reduction of erection time, reduce cost construction method for concrete shaft wall module masonry.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of construction method for concrete shaft wall module masonry is characterized in that comprising with the next stage:

(3) build the sole plate concrete: according to designing requirement construction sole plate, behind the base plate reinforcing bar binding, pile up first floor module before building the sole plate concrete, and take fixation, prevent that first floor module is floating, up and down dislocation; Pre-buried vertical reinforcement in the module hole, the filling core concrete of first floor module must be built synchronously with the sole plate concrete;
(4) vallum phantom piece: described wall body module comprises left frame, left frame and is connected rib, on the last datum of on the left side frame and left frame, following datum, preceding datum and the back datum, be provided with groove and fin respectively accordingly, the datum middle part is provided with intermediate groove on the connection rib, fin in the middle of the middle part of datum is provided with down; Middle fin is connected by arc with left frame, left frame, and the jointing that is positioned at intermediate groove and left frame, left frame on datum on the connection rib is respectively equipped with the twice groove, when building by laying bricks or stones, can place horizontal reinforcement in the groove on connecting rib;
1., require the double-sided belt line, carry out grievances according to the size of row's piece, the hole is built by laying bricks or stones, foreign material are in time cleared up in the hole in, and guarantee that its groove and fin that reaches front and back up and down aims at mutually;
2., the grievances height is as the criterion with four to five skins, should not surpass five skins, and guarantee groove and the fin level that it is suitable for reading, every base one skin is placed horizontal reinforcement according to designing requirement on just in the groove on connecting rib;
3., devious slightly for wall body module because of its specification, adopt the module levelling of cutting out saw at its tongue and groove position;
4., vertical reinforcement within the walls, before building the back grout by laying bricks or stones, insert, all must insert in each hole;
(5) perfusion concrete:
1., adopt diameter to vibrate back and forth or reinforcing bar that diameter is not less than Φ 16 carries out tamping less than the internal vibration rod of 30mm, fast inserting taken out slowly;
Vibrating spear is not run into the building block hole wall when 2., vibrating;
3., vibrating time requires: slurries overflow from groove and fin seam and get final product;
4., produce displacement, before the perfusion concrete, body of wall is carried out bracing reinforcement in order to prevent body of wall;
(6) precast lintel and cover plate are installed: after the perfusion concrete finishes, precast lintel and cover plate are installed, are need not to sit slurry;
(7) the plate seam is filled out embedding: closely knit with the perfusion of C20 fine-stone concrete to the plate seam;
(8) build manhole by laying bricks or stones: the manhole pit shaft adopts the arc module masonry, and ductile iron five preventing well covers are installed;
(9) backfill: fertile groove backfill simultaneously around the body of wall.
Aforesaid construction method for concrete shaft wall module masonry is characterized in that in the described soil excavation stage, must take corresponding side slope strutting means when cutting depth surpasses 1.5m; When adopting mechanical equivalent of light excavation, should keep and be no less than the artificial clear groove of the thick soil layer employing of 100mm.
Aforesaid construction method for concrete shaft wall module masonry is characterized in that in the described soil excavation stage, no matter was mechanical equivalent of light excavation or artificial grooving, did not all answer disturbance base soil or backbreak; Ruo Fashengji regolith disturbance or when backbreaking then must be carried out ground and handle.
Aforesaid construction method for concrete shaft wall module masonry is characterized in that in the described soil excavation stage, when in the scope of the following 500mm of design ground basal surface underground water being arranged, taked construction to fall drainage measure.
Aforesaid construction method for concrete shaft wall module masonry is characterized in that building by laying bricks or stones the manhole stage described, and is firm with the C20 concrete around the well lid, and the well lid 100mm that is above the ground level has to be not less than 1% outside drainage grade on every side.
