Abstract
Disclosed is a construction method of a pull-rod-free pier body template of a dolphin pier. Every 16 cm height of pier body is divided into five layers for machining and construction of a steel template according to the positions of a pier body steel apron and a mooring recess; every first layer of template is 2.0 m + 0.5 m, every second layer of template is 2.0 + 0.5 m, every third layer of template is 2.85 + 0.5 m, every fourth layer of template is 3.2 m + 0.5 m, and every fifth layer of template is 3.95 m; different template models are adopted at different corresponding heights of the pier body template respectively; the same model of template is only used once on every pier body and is detached to move to the corresponding working surface of the next pier body. According to the construction method of the pull-rod-free pier body template of the dolphin pier, the construction process of the pull-rod-free truss type pier body template is safe and convenient and high in construction efficiency; the surface of concrete after form removal is free of hole reserved through a pull rod and accordingly the durability of the concrete is ensured and the same color of the appearance of the concrete is achieved; the common fault of the quality of the concrete is reduced, the turnover efficiency of the template is improved, and the engineering cost input is reduced due to the design of a positioning guide template.
Description
Technical field
The invention belongs to dolphin technical field, particularly relate to a kind of dolphin non pull rod type pier body formwork construction method.
Background technology
Along with the development of engineering construction, template deformation requirement when not only having concreting to various high tower, high pier, construction period, also more and more stricter to the requirement of the presentation quality of tower body, pier shaft, also more and more higher to requirement attractive in appearance.Current tower body, pier construction traditional method are: in the construction of tower body, pier shaft adopt through in body to the template of drawing rod-pulling type, although the processing of this template is simple, template is relatively light, but formwork integral rigidity is little, need with to pull bar during construction, to such an extent as to concrete surface draw-bar eye is many, process loaded down with trivial details, concrete surface unsightly, and after pull bar corrosion, the etching channels of reinforcing bar in concrete structure will be formed, have in the engineering of particular/special requirement reinforced steel bar rust preventing inapplicable in ocean engineering or some.
Non pull rod type pier body formwork have easy accessibility, improve template turnover, without scaffold construction, do not need to adopt other steel and to pull bar, after form removal, on pier shaft nothing to pulling eye, outward appearance comparatively adopts features such as the pier shaft of pull bar are attractive in appearance.Such as, approach channel engineering on Changzhou key water control project three line four line, arrange dolphin 55 altogether, point A, B two berthing space arrange, wherein A district (in boat 0+253.0-0+578.0) is close to ship lock and adjusts suitable section, and arrange 28 dolphins (respectively arranging 14 on the left of Third-Line Shiplock and on the right side of four line ship lock), B district (in boat 1+094.0-1+774.0) is near entrance erea, arrange 27 dolphins, adjacent two pier center distance are 25.0 meters.Dolphin pier shaft is variable cross-section, the pier shaft two sides gradient is 1:0.1, pier shaft back slope is 1:0.2,2 row steel guard timbers are provided with at side, pier shaft facade forward position 28.50 ~ 16.50m elevation, steel guard timber projective structure surface 5cm, and a mooring tabernacle is had every 1.85m in 19.30 ~ 26.7m elevation, tabernacle is recessed structures surface 100cm.
Summary of the invention
The object of the present invention is to provide a kind of construction method of dolphin non pull rod type pier body formwork.
The technical solution used in the present invention is:
A kind of construction method of dolphin non pull rod type pier body formwork, according to pier shaft steel guard timber and mooring tabernacle position, pier shaft high for 16m is divided into 5 layers of processing and construction carrying out steel form, first floor template is 2.0m+0.5m, second layer template is 2.0+0.5m, third layer template is 2.85+0.5m, 4th layer of template is 3.2m+0.5m, layer 5 template is 3.95m, the different respective heights of pier body formwork all adopts different template models, same model template only uses once at each pier shaft, then removes and moves on the corresponding work plane of next pier shaft; During the upper mould of construction, the 0.5m template of lower one deck template of having constructed is as locating guiding template, make that a whole set of flowing water steel form is segmented to be applied on adjacent some piers, the template of removing last pier shaft carries out polishing on ground, after oiling, next pier shaft of direct lifting is constructed, and every one deck template is divided into four pieces, and each face die plate of pier shaft is a monoblock, there being the position of steel guard timber to arrange the projecting surface board slot with the identical modulus of steel guard timber built-in fitting, during construction, built-in fitting and steel facing are adjacent to.
The construction method of described dolphin non pull rod type pier body formwork, does not arrange template to steel guard timber position, directly slots in template according to built-in fitting size, during construction directly by installation of embedded parts in relevant position, take corresponding mortar leakage prevention measure in outside.
The construction method of described dolphin non pull rod type pier body formwork, truss junction outside template connects with flange, levels truss in single form is with Bolted angle connection, at firm panel and vertical framework seam crossing, long 13cm is set, the triangular form rubber strip grouting of wide 1cm, grouting rubber strip adopts nail nail to be fixed on the lumps of wood of the 10# channel-section steel of vertical framework side; Firm panel and levels cross form stitching portion are arranged to negative and positive faulting of slab ends and are overlapped, and add double-sided tape mortar leakage prevention when constructing at edge joint position.
Beneficial effect of the present invention, the present invention is without pull bar truss pier formwork, and in work progress, safe ready, efficiency of construction are high; After form removal, concrete surface does not have hole that pull bar is left a blank, and ensure that concrete durability, makes pier shaft concrete appearance solid colour yet; The design of locating guiding template decreases common fault of concrete quality, improves all transfer efficients of template, decreases engineering cost input.
Detailed description of the invention
