Abstract
The utility model relates to a seamless connection cutoff wall sheet steel form, which relates to a tool which is used for constructing by a cutoff wall, in particular to a sheet steel form which needs to be used when a sinking mould method is adopted to build the cutoff wall. The sheet steel form adopts a steel square outer frame 1 with a cavity structure 7 to be submerged in a designed impervious depth under the condition that a flap pile tip 2 is closed, materials such as concrete and the like which are pre-allocated are evenly injected through a material filling opening 6 on a mould body, the mould is pulled out through a vibration mode and the like, slurries are injected through a lubricating pipe 3 in the process of sinking and pulling out, the flap pile tip is automatically opened when the mould is pulled out, materials which are injected in the cavity are left in a ground layer, which form a consolidated pile body after hardening. Moulds are sleeved through 4, 5, one pile body is connected with another pile body without seam, and finally a wall body is formed, and the wall body plays the anti-seepage function. The sheet steel form excellently solves the quality problem of bad continuity of the wall body of an anti-seepage wall in long term, which has novel and special design and simple structure, and simultaneously solves the shortcomings of repeat procedures of the construction of the anti-seepage wall, bad progress and the like, and saves a great amount of production cost.
Description
Technical field
The utility model relates to the instrument that a kind of impervious wall uses, and is specially the steel form that need use when adopting heavy mould mode to construct impervious wall.
Background technology
Impervious wall is the requisite measure of a foundation construction on the engineering, uses very extensive.The water conservancy dykes and dams, reservoir seepage-proofing, the building foundation pit excavation, dock construction etc. all needs to utilize impervious wall to guarantee the success of excavation of foundation pit.The continuity of impervious wall then is the basic demand of antiseepage.The construction technology of impervious wall has: the heavy form walls of vibration, splitting curtain grouting, high pressure jet grouting, geomembrane anti-seepage, concrete cut or the like, various technologies have different compliance and limitation.In all these technologies, maximum problem is how to guarantee the continuity of leakage proof wall.The continuity that comprises length direction and depth direction.
Before the utility model is made, the thinking of this problem that solves is that the perpendicularity deviation when requiring the pile body construction is controlled in the very little scope, to guarantee the continuous of depth direction, length direction then adopts tenon formula joint, rigid joint, junction block method, overlaps drill hole, volume method of substitution etc., with the continuity of assurance impervious wall, these modes, cost is higher, complex process, work efficiency is lower, and relatively stricter to the requirement of geological conditions, actual effect is good inadequately.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, and the defective of the continuous assurance difference of existence aims to provide a kind of working steel form of impervious wall continuity that guarantees reliably.
Technical solutions of the utility model: two this programme design steel forms (1) that adopt same size, the bottom flap valve of closed steel form, become pointed, be positioned over design attitude,, be pressed in the soil with vibration or static pressure power, simultaneously, open lubrication management (3), inwardly inject clear water or mud, work the frictional force and the foundry loam phenomenon that reduce in pile sinking and the pile pulling process.After the degree of depth reaches, stop to sink.The connection back (4) of another one steel form is aimed at the connection sunny side (5) of one of front, after putting, sink.So continuously carry out, form the impervious wall of continuous seamless.
Advantage and effect: use the utility model, can build seamless impervious wall.Characteristics are simple in structure; Cost is low; The work efficiency height.Do not produce pollutions such as mud.
Description of drawings
Fig. 1 is that the utility model structural representation Fig. 2 is the utility model section of structure
The specific embodiment
With reference to Fig. 1,2, the utility model adopts the steel plate welding, forms rectangle steel sheet frame (1), in the one side, the connection back (4) is set, and opposite side is provided with and connects sunny side (5), and upper side has charging aperture (6), establishes lubricated water pipe (3) at sunny side.(1) bottom is provided with flapper pile tip (2).During construction, (1) is connected power source, opens (3), closed (2), sink to the degree of depth after, stop.Second steel form is in place, opens lubricated water pipe, and closed flap valve (2) adopts the mode of back snapping sunny side to be connected the sinking steel form with first steel form.When extracting first steel form, put into the material of capacity, after the curing, just formed the impervious wall of seamless link.
Claims (5)
1, seamless link impervious wall steel form, it is characterized in that rectangle steel sheet frame (1) has cavity (7), rectangle frame minor face one side is the back (4) of linkage, opposite side is the sunny side (5) of linkage, the template bottom is flapper pile tip structure (2), top, side sprue (6), and the lubricated slurry pipe (3) that the linkage sunny side comprises is formed.
2, seamless link impervious wall steel form according to claim 1 is characterized in that rectangle steel sheet frame (1) cloudy (4) sun (5) linkage, distribution minor face both sides.
3,, it is characterized in that negative and positive linkage (4), (5) are " T type groove " type and " ∏ " type according to claim 1,2 described seamless link impervious wall steel forms.
4, seamless link impervious wall steel form according to claim 1 is characterized in that having lubricated slurry pipe in the linkage sunny side (5).
