Abstract
The utility model discloses a kind of mud-dumping yard overflow well derrick in water conservancy equipment field, comprise the column of four distributions that are square, each column is made up of two channel-section steels, wherein the outside portion of secondary channel-section steel is welded on the outer bottom of major trough steel, be oppositely arranged between two between major trough steel on four root posts, and be connected through gate sheet each other, be oppositely arranged between two between secondary channel-section steel on four root posts, and be connected through gate sheet each other, in the utility model, each column bears the horizontal force of gate sheet, and Self-stabilised post passes to another column by the special gate sheet laid, thus maintenance equilibrium of forces, the change past, independently column bore two-way horizontal power is overall derrick force structure, make structure more compact with economy, construct convenient simultaneously, can be used in the construction of mud-dumping yard overflow well.
Description
Technical field
The utility model relates to a kind of overflow well, particularly a kind of overflow well derrick.
Background technology
Adopting strand suction or bucket-wheel suction dredger to implement dredging to river course, is one not only economy but also rational construction method.It efficiently solves the contradiction that dry river construction method and shipping, irrigation, flood discharge etc. produce, the huge benefit for social creativity.Due to strand suction or bucket-wheel suction dredger dredging, that the dredge pump utilizing dredge boat to configure combines with mud pipe and to carry (volume ratio that original soil body volume accounts in muddy water mixture is generally 10-20%) muddy water mixture, to mud-dumping yard or spoil area throwing, in mixture, soil particle is after mud-dumping yard precipitates completely, remaining water outwards must discharge from the withdrawal nozzle arranged, to guarantee that the volume of the soil body is deposited in mud-dumping yard or spoil area.This process is continuous print operation.
Through facts have proved for many years, the use safety of mud-dumping yard cofferdam, withdrawal nozzle, the turbidity of withdrawal nozzle remained water discharge and the influence degree to surrounding enviroment, also exist inseparable relation with the design of withdrawal nozzle, construction form.Especially, along with the develop rapidly of Chinese national economy, today that land resources is increasingly in short supply.A medium-sized dredging works is by the high 3 meters of calculating of mud-dumping yard side piling in the past, and required mud-dumping yard land used is hundreds of mu thousands of mu at most at least.For making full use of limited land resources, mud-dumping yard plan spoir height is all significantly improved than before, and part dredging works spoir height has reached 7 meters.The increase of spoir height, virtually produce huge prestige association to the use safety of mud-dumping yard cofferdam, withdrawal nozzle, conventional unlimited wide top overflow weir (or adjustable unlimited overflow weir) withdrawal nozzle structural shape of making over is subject to serious challenge.
Water-break pattern conventional in prior art is the adjustable overflow well formula of framed bent.Framed bent adjustable overflow well formula has heavy few muscle brick to mix derrick geometry and light-duty steel derrick geometry.Due to the few muscle brick mix structure of heavy type not recuperability, environment is easily impacted, fabrication cycle is long, requires the shortcomings such as height, current less use to bearing capacity of foundation soil, traffic route.
Utility model content
The purpose of this utility model is to provide a kind of mud-dumping yard overflow well derrick, and its structure is simple, and it is convenient to reclaim, and constructs convenient.
The purpose of this utility model is achieved in that a kind of mud-dumping yard overflow well derrick, comprise the column of four distributions that are square, each column is made up of two channel-section steels, wherein the outside portion of secondary channel-section steel is welded on the outer bottom of major trough steel, be oppositely arranged between two between major trough steel on four root posts, and be connected through gate sheet each other, be oppositely arranged between two between the secondary channel-section steel on four root posts, and be connected through gate sheet each other.
During the utility model construction and installation, first the utility model welding processing in factory building is completed, be transported to job site again, only simple lifting tool need be used to sling to correct position by the utility model, bottom it and top is fixed and can be completed construction, compared with prior art, the beneficial effects of the utility model are: in the utility model, each column bears the horizontal force of gate sheet, and Self-stabilised post passes to another column by the special gate sheet laid, thus maintenance equilibrium of forces, ensureing under certain rigidity condition, column only plays the effect of power transmission, now, gate sheet is by bidirectional force effect, namely the axial load that the evenly distributed load of horizontal direction liquid and column pass to gate sheet is born, changing that in the past independently column bore two-way horizontal power is overall derrick force structure, makes structure more compact with economy, constructs convenient simultaneously.The utility model can be used in the construction of mud-dumping yard overflow well.
Convenient in order to make the utility model be welded, structure is more stable, and the end face of described secondary channel-section steel is mutually concordant with major trough steel sidepiece.
In order to strengthen reliability when the utility model uses, be also connected with diagonal angle bridging stiffener between described four root posts, described diagonal angle bridging stiffener is bolted the top at column.
In order to strengthen the stability of this apparatus structure, between described four root posts, be connected with connection beam, described connection beam be bolted from bottom to top layout level on column.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the utility model center pillar structure schematic diagram.
Wherein, 1 major trough steel, bottom 1a, 1b sidepiece, 2 secondary channel-section steels, 2a sidepiece, 2b end face, 3 gate sheets, 4 diagonal angle bridging stiffeners, 5 connection beam.
Detailed description of the invention
A kind of mud-dumping yard overflow well derrick as Figure 1-3, comprise the column of four distributions that are square, each column is made up of two channel-section steels, wherein the outside portion 2a of secondary channel-section steel 2 is welded on the outer bottom 1a of major trough steel 1, be oppositely arranged between two between major trough steel 1 on four root posts, and be connected through gate sheet 3 each other, be oppositely arranged between two between secondary channel-section steel 2 on four root posts, and be connected through gate sheet 3 each other, the end face 2b of secondary channel-section steel 2 is concordant with major trough steel 1 sidepiece 1b phase, between four root posts, top is also connected with diagonal angle bridging stiffener 4, connection beam 5 is arranged in derrick stem height direction, diagonal angle bridging stiffener 4 and connection beam 5 are bolted and are connected on column, ensure derrick integral rigidity.
During the utility model construction and installation, first the utility model welding processing in factory building is completed, be transported to job site again, simple suspender only need be used to be sling by each for the utility model component to install by regulation operation to correct position, first, complete the connection of each upright post basic, and carry out the steady job of each column; Then from bottom to top install connection beam 5, then install diagonal angle bridging stiffener 4, finally from top to bottom firm attachment bolt, can complete construction, and the diagonal angle bridging stiffener 4 and the column connection beam 5 that are arranged on column top enhance reliability of structure.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
