Technical field
The utility model relates to a kind of pile foundation reinforcement technology, particularly relates to a kind of good airproof performance, pile foundation reinforcement device easy to assembly.
Background technology
At present, the disease that Bridges in Our Country underwater pile causes due to a variety of causes, damage defect, earthquake cause the phenomenon of destruction more, and for this type of disease, traditional pile foundation reinforcement, necessary cofferdam, Foundation Anti-seepage and drainage of foundation pit be time of at substantial and expense often, and take space, navigation channel in work progress, social influence is large, becomes the thorny problem that underwater foundation reinforcing technique faces.In order to solve this problem, also have devised some devices at present, generally these devices are arranged on pile foundation periphery by splicing, and the ponding then between draw-out device and pile foundation, finally builds.And these devices are all simple concatenation at present, as adopted circular dies, by simple Flange joint between mould and mould, and seal with caulking gum, but one, this structure connects stable not, and another sealing performance is also good not, and carry out under water placing and fixing due to operating personnel, need manually to carry out adjusting position, operate fast very inconvenient.
Summary of the invention
The utility model mainly solves traditional approach and carries out pile foundation reinforcement, expends time in and the problem of expense, provides a kind of quick and easy for installation, pile foundation reinforcement device that the expense that expends time in is few.
Another goal of the invention of the utility model solves general pile foundation reinforcement device syndeton instability, and the problem of sealing difference, provides a kind of good airproof performance, easy to assembly, constitutionally stable pile foundation reinforcement device.
The utility model solves the technical scheme that its technical problem adopts: a kind of pile foundation reinforcement device, be nested with in pile foundation, be spliced by some casings, described casing is made up of left and right two half-unit, turn up along edge and be formed with annular connecting plate in the two ends up and down of described half portion, and the upper end edge edge of half portion has upwards extended to form retaining wall, the lower end edge edge indent of half portion forms the slot corresponding with retaining wall, the side of half portion turns up and is formed with side junction plate, the side junction plate correspondence of described casing two half-unit is spliced mutually and fixes, caulking gum is provided with between side junction plate, the annular connecting plate of upper and lower casing half portion splices mutually and fixes, caulking gum is provided with between annular connecting plate, the back wall surface of casing upper end is provided with sealing ring, retaining wall is inserted into the slot being positioned at top casing, the slot of casing lower end then matches with the retaining wall being positioned at below casing.The utility model is made up of some casings that connects, and each casing is made up of two semicircular half portion, and the side junction plate of two half-unit connects when mounted, and be provided with caulking gum between side junction plate, be then fixed by bolt, formation is tightly connected.After two half-unit is spliced into casing, two semicircular retaining walls also conglobate retaining wall of shape, two semicircular slots become circular socket.When upper and lower casing is installed, the retaining wall of below casing is inserted in the slot of top casing, retaining wall external surface is provided with sealing ring, the annular connecting plate of casing is also interconnected up and down in addition, also caulking gum is provided with between annular connecting plate, then be fixed by bolt, define in plane like this between casing and vertical direction double seal, not only sealing performance is better, and rise extend the path that water enters casing inside, compare and existingly pass through Flange joint, the structure of caulking gum is only set on flange surface, this programme sealing performance is better, more not easily intake.
As a kind of preferred version of such scheme, the annular connecting plate of described half portion upper and lower side is provided with some vertical to having pilot hole, device is also provided with guide peg, and guide peg is through in corresponding pilot hole, by half portion string together.This guide peg by each half string together, plays guide effect when mounted, each half can be superimposed together very accurately, make between half portion and half portion like this, and the connection between casing and casing is more tight, also makes better tightness.This guide peg makes easier for installation in addition, during installation, first set the casing of bottommost, then bottom casing plugs guide peg, half portion is then installed only to be needed to insert on the guide bar, be placed on installation site along guide peg, regulate under water without the need to operating personnel, operating process is according to convenient and swift.
As a kind of preferred version of such scheme, annular connecting plate one end of described half portion is protruded and is provided with dop, draw-in groove has been bent to form at the annular connecting plate other end, when the split of two half-unit phase, the dop of a half portion is inserted in the draw-in groove of another half portion, the draw-in groove of a half portion then matches with the dop of another half portion, and is provided with caulking gum in draw-in groove, and dop seals with draw-in groove and is connected.The structure of dop draw-in groove split is set in this programme between the annular connecting plate of two half-unit, original two annular connecting plate joinings and dual-side junction plate points of intersection coincide structure disperses are on one point come, the sealing ring be arranged on like this between the caulking gum of dual-side junction plate, two annular connecting plates can not intersect on one point, make to connect between each caulking gum, sealing ring more tight, further increase sealing.
As a kind of preferred version of such scheme, stack for staggering between the half portion of described upper and lower casing, angled between the split face of a casing halves and the split face of adjacent casing halves.The structure that this programme misplaces superimposed makes to be connected more fastening stablizing between casing with casing on the one hand, and what also make sealing to do on the other hand is better, more not easily intakes.
As a kind of preferred version of such scheme, annular connecting plate and the lateral wall intersection of described half portion are provided with reinforcing rib.Improve the intensity of annular connecting plate, installation is stablized more fastening.
As a kind of preferred version of such scheme, after each half is spliced to form tubular structure, the inwall of tubular structure is provided with some built-in pipes.Built-in pipe is used for injecting cement paste by below, and the ponding of such cement paste from the bottom up between remover and pile foundation, makes cement paste fill up gap, effectively reinforces former damage pile foundation and repairs.
The utility model has the advantages that: overall structure is closely stablized, many places adopt interface arrangment, and adopt wrong overlaying structure, further enhance the sealing of device.By arranging guide peg structure, making easier for installation simultaneously installation also more accurately, facilitating operating personnel, improve operating efficiency.
