Description
Technical field
The utility model belongs to bridge water pile foundation pouring construction field, is specifically related to a kind of device for detecting underwater cast-in-place pile laitance thickness, when constructing for bored pile filling concrete, to the detection of cement paste laitance thickness in stake holes.
Background technology
Under water in filling pile construction, when filling concrete is to position close to stake top, need to verify laitance thickness, and then determine concretely to build height.Generally because the difference of the factors such as concrete proportioning, construction quality, mud balance, speed of application, pile foundation length causes laitance thickness not to be an established data, plummet is in most cases utilized (usually to utilize φ 25, length 40cm reinforcing bar is made) detection laitance thickness, and then determine a heights of roofs, ensure pile crown quality.Utilize plummet to detect laitance thickness, completely with institute in surveyor's hand carry plummet before contacting laitance end face with the sensation contacting Different Weight after top of concrete and judging.Plummet can not be too light but can not be too heavy, otherwise feel can be not obvious, this method mainly relies on the decrease speed of experience, plummet, buoyancy size judges, objectively comparatively not large according to error in judgement, most cases, for ensureing pile crown quality, all adds certain depth again to laitance thickness on the basis of micro-judgment, concrete waste can be caused like this, if and judge inaccurate, laitance thickness judges not enough, then pile crown coagulation may be caused off quality.How accurately judging laitance thickness, ensure pile crown concrete quality and avoid concrete waste, is the technical problem being badly in need of solution under water in filling pile construction.
Summary of the invention
The purpose of this utility model is under the prerequisite guaranteeing safely, meet construction usage, provides a kind of device that accurately can judge underwater cast-in-place pile laitance thickness, thus ensures pile crown quality and avoid concrete to waste.
For achieving the above object, the utility model takes following technical scheme:
A kind of underwater cast-in-place pile laitance detecting thickness device, is characterized in that: comprise a conical filter net and a barre; Described conical filter net comprises a retainer ring and the isometric filtration muscle of Duo Gen, and described in each upper end edge filtering muscle, retainer ring periphery is equally spaced and welds, and each lower end of filtering muscle is converged and weld together; Described barre is the plane orthogonal at steel plate or the reinforcing bar of a strip, barre and described retainer ring place, and the lower end of barre is welded with described retainer ring.
The utility model designs mainly through work principle of filter, and because laitance is mainly cement paste, primarily of water, cement, fine sand composition, this device reintroduces after being deep into laitance position, and conical filter net inner filtration does not go out the stone of greater particle size; Lift out after being deep into concrete position, the stone in concrete can be crossed filtration muscle and pulls and be filtered out, thus judges the position of top of concrete, and then judges the thickness of laitance.
The utility model, for detecting underwater cast-in-place pile laitance thickness, relative to traditional plummet judgment mode, has accuracy of judgement, the advantage such as easy to operate.For 1 φ, 2.5 meters of pile foundation constructions, if laitance thickness many judgements 10cm, then waste concrete 0.5m
3; If laitance thickness judges not enough, then pile crown can be caused off quality, and need intensification to dig out pile crown pile extension again, construction quality, cost, progress all can impact.Visible, the use of this device can obtain good Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Detailed description of the invention
As shown in Figure 1, the utility model comprises a conical filter net and a barre; Described conical filter net comprises a retainer ring 1 and the isometric filtration muscle 2 of Duo Gen, and described in each upper end edge filtering muscle 2, retainer ring 1 periphery is equally spaced and welds, and each lower end of filtering muscle is converged and weld together; Described barre 3 is the plane orthogonal at steel plate or the reinforcing bar of a strip, barre and described retainer ring 1 place, and the lower end of barre 3 is welded with described retainer ring 1.
When the utility model is specifically implemented, the diameter of described retainer ring can be set to 20-30cm, the height of described conical filter net is set to 15-25cm.
When filtration muscle upper end is welded with retainer ring, the spacing between the upper end of adjacent head muscle is set to 3-4cm.
As a specific embodiment, retainer ring can adopt φ 10 reinforcing bar reinforcing bar to bend, termination butt welding forms, and filters muscle and utilizes some φ 10 steel-bar one end to weld with retainer ring, spacing 3-4cm, the other end converges and is welded in a bit, form a conical filter net, barre adopts the steel plate of φ 12 reinforcing bar or wide 1-2cm, and its length suitably can adjust according to hole depth, one end and retainer ring welded together, for lifting conical filter net.
Under water in filling concrete process, when needing detection underwater cast-in-place pile laitance thickness, first tentatively judge that top of concrete reaches design elevation substantially according to filling concrete side's amount, recycle after this device is deep into this position, lift up and down several under, then be brought up, whether observe in conical filter net has stone to filter out, as without stone, illustrate that this position is all laitance, there is no concrete, then progressively detecting location is deepened, until stone occurs, again with this height multi-point sampler, finally judge laitance thickness with most deep location place, and then determine that height is built in pile crown top casting.
For more accurately judging laitance thickness, when the utility model is specifically implemented, length scale 4 can be set on described barre 3.
