Description
Technical field
The utility model relates to the geological exploration techniques field, relates in particular to a kind of static sounding mud that is used for engineering geologic investigation and pours into the formula reamer.
Background technology
Static sounding is a kind of project in the work of engineering geologic investigation in-situ test.Along with urban construction scale constantly enlarges, high buildings and large mansions are rised sheer from level ground, super-huge bridge Beam, overhead grade separation constantly build up, integrated mill, enterprise's construction constantly enlarge, infrastructure requires to improve, the corresponding raising of the technology of engineering geologic investigation, the technical requirements degree of depth of static sounding injection also will improve constantly.Along with the increase of depth of penetration, hole wall also increases the frictional resistance of feeler lever, and total penetrating power also just increases, and therefore will finish the quiet spy of deep hole and just take manpower, expense material resources, time-consuming more, and cost is opened money and increased.Reach and finish the quiet spy injection of deep hole smoothly, just must innovate in that injection is technical, satisfy the technical requirements of engineering geologic investigation.
Reamer is the assistive device that is used for a kind of effective increase depth of penetration of static sounding injection work.Its objective is when quiet inspecting hole injection, utilize the reamer reaming to realize enlarging the aperture, reduce the technical purpose of soil layer, the deep hole static sounding can be finished in disposable injection, or increase disposable depth of penetration effectively the sidewall frictional resistance of feeler lever.
The effect of reamer is that the reaming by reamer produces the gap between hole wall and feeler lever, to reduce the frictional resistance of soil layer to bar.But existing reamer can only carry out disturbance with the soil between feeler lever and the hole wall, can not carry out reaming and guard aperture wall effectively, can not make feeler lever and hole wall produce the gap and reach the purpose that reduces frictional resistance.Therefore, the static sounding of the deep hole that resistance is bigger in the prior art can not disposablely be finished, and can not can bear under the prerequisite of pressure at probe, and the soil layer in any area is carried out disposable deep hole injection, and its reason mainly is:
1, quiet inspecting hole at first produces a gap through the reamer reaming between hole wall and the feeler lever, but after this gap generation, vacuum negative pressure produces thereupon in the hole.If can not solve vacuum negative pressure in the hole, hole wall nature is on retracting to around the feeler lever under the effect of vacuum negative pressure and pyriform compression variation, so in fact the reaming of prior art can only play perturbation action.
2, there is not the guard aperture wall material between hole wall and the feeler lever, the sandy soil hole of can collapsing naturally adds vacuum negative pressure effect in the hole, the water in the sandy soil layer hole can be sucked in the hole.The Ta because the outflow of pore water, sandy soil also can be collapsed naturally, the feeler lever frictional resistance also just can not reduce effectively.Even perforate on reamer though solved negative pressure of vacuum problem and the passage that transports of having set up the retaining wall material, must return zero because quiet spy operation is popped one's head in during actual the use, when feeler lever was up carried, the hole on the reamer can be stopped up by sand naturally.When injection again, passage is blocked, and original problem still exists.
Therefore, existing reamer in the deep hole injection owing to can not solve the vacuum negative pressure problem, can not slurry conveyed, also just can not reduce the sidewall frictional resistance effectively, total penetration resistance also just can not solve effectively.Therefore, the deep hole injection can not disposablely be finished, but to carry out the gradation punching, be pressed into, punching again, be pressed into again, so both wastes of manpower, material resources, time, operating efficiency can not improve again, and construction period elongates, can not guarantee to pop one's head under the prerequisite that can bear pressure, any area, any soil layer are carried out the disposable injection work of deep hole.
Therefore, those skilled in the art is devoted to develop a kind of reamer that can effectively realize disposable deep hole injection.

The specific embodiment
Be illustrated in figure 1 as the main core bar 1 in the reamer of the present utility model.Main core bar 1 is a hollow connecting rod, and material is No. 45 steel, and improves the intensity of steel through heat treatment.Main core bar 1 has a cavity 11 that is used to pour into mud.Bar wall 12 is radially gone up symmetry and is offered two mud holes 13,14, and mud hole 13,14 all connects with cavity 11.
The two ends of main core bar 1 are respectively link, and an end has internal thread can fixedly connected other main core bars, and the other end has external screw thread can connect seal nipple, make the quiet spy can normal injection.
Because one section slide-and-guide face 15, on the external surface of the stroke end of this slide-and-guide face 15, has a step 16 on the external surface of main core bar 1.
As shown in Figure 2, seal nipple 2 is used to connect the feeler lever on the probe and offers the endoporus 21 that passes through for probe wire.The tail end of endoporus 21 is the endoporus link 23 of fixedlying connected with main core bar 1, has internal thread.Screw thread in the reamer can be chosen wantonly, and not necessarily square thread firmly just can as long as be threaded.
The external diameter of the endoporus link 23 of seal nipple 2 is greater than main core bar 1 external diameter.
As shown in Figure 3, reaming sleeve 3 is a hollow revolution, is set in slidably outside the main core bar 1.The main effect of reaming sleeve 3 is that hole wall is enlarged, makes between hole wall and the feeler lever and produces the gap, and slurry conveyed.
Have one section cooperation slide plane 32 identical in the inner chamber 31 of reaming sleeve 3, also have and corresponding pulp space 33,13,14 positions, mud hole with slide-and-guide face 15 diameters.
Reaming sleeve 3 also has the outer reaming face 34 of a truncated cone.Outer reaming face 34 constitutes a reaming angle with the axis of main core bar 1.
In the present embodiment, the reaming angle is 168 °.In other embodiment of the present utility model, the reaming angle is preferably 150 ° to 175 °.
When reamer of the present utility model is assembled, at first pulp space 33 1 ends of reaming sleeve 3 small end from main core bar 1 is inserted in, the cooperation slide plane 32 of reaming sleeve 3 is slidably cooperated with the slide-and-guide face 15 of main core bar 1, and with the top dead centre of the step 16 on the main core bar 1 as reaming sleeve 3 displacement stroke.
Then, one rubber seal 22 is set in the endoporus 21 of seal nipple 2, the endoporus link 23 of seal nipple 2 is connected with external screw thread on the main core bar 1, and the small end that makes main core bar 1 is screwed 22 distortion of extruding rubber seal with the extruding probe wire, form sealing, stop the mud prize to flow to probe and go up (probe wire connects probe and instrument, accepts test data).Seal nipple 2 mainly is to stop the damage to the probe line insulation of pressure that mud produced by rubber seal 3 in the feeler lever endoporus, makes the probe can operate as normal.
Because the external diameter of the endoporus link 23 of seal nipple 2 is greater than main core bar 1 external diameter, so both connect the back and form a ladder 24 (see figure 4)s, are used as the lower dead center of reaming sleeve 3 displacement stroke.
Because the position-limiting action of top dead centre and lower dead center, reaming sleeve 3 can only be done slide displacement between the upper and lower stop of main core bar 1.
Reamer of the present utility model in concrete the use, quiet spy injection operation when whenever adding a feeler lever, in time with the mud injection to 11 li of the cavitys of main core bar 1, pass through full getting final product.
As shown in Figure 4, when the reamer test, because outer reaming face 34 is subjected to the reaction force of earth, reaming sleeve 3 slides into top dead center position along main core bar 1, and the inner chamber 31 of reaming sleeve 3 is opened.
At this moment, on the one hand because hole wall produces vacuum negative pressure through reaming, on the other hand, the position in mud hole 13,14 is corresponding with pulp space 33, under the effect of the mud vacuum negative pressure in self gravitation and hole in the cavity 11 of main core bar 1, from cavity 11, overflow reamer, flow between the gap of hole wall and feeler lever through mud hole 13,14 and in the inner chamber 31 of pulp space 33 by reaming sleeve 3.At this moment, vacuum negative pressure also progressively is decreased to disappearance naturally.
Because mud balance is bigger, denseness is higher, therefore, will produce the mud skin on hole wall, plays the effect of pressing hole, retaining wall, and makes feeler lever and hole wall can keep certain interval.Meanwhile, mud also plays the lubrication between feeler lever and the hole wall, has reduced frictional resistance.
As shown in Figure 5, when quiet spy operated back zero, because the aperture of boring is subjected under the effect of the compression of centrifugal force and soil layer stressor layer, the aperture dwindled the diameter less than reaming sleeve 3.Carry on the reamer this moment, and reaming sleeve 3 is subjected to hole wall to its sidewall frictional resistance that makes progress, and the tail end of reaming sleeve 3 is stressed, and reaming sleeve 3 slides into bottom dead center position along main core bar 1, and the inner chamber 31 of reaming sleeve 3 is closed.
At this moment, the mud overflow channel that forms at the test state has stoped sand to enter in the passage of reamer owing to closing of inner chamber 31 stopped up, and has prevented that slurry channel from being stopped up by sandy soil.
Because said structure can not stopped up by the silt in the boring in the course of work that the mud overflow channel is carried on feeler lever or test replaces repeatedly.Mud reamer of the present utility model just plays the effective efficiency that deducts vacuum negative pressure in the hole, slurry conveyed, minimizing sidewall frictional resistance, has realized the technical purpose of the disposable injection of deep hole static sounding effectively.
In concrete enforcement, the outside dimension of reaming sleeve 3 can be selected for use according to different soil layers.
The quiet spy injection of deep hole is carried out in area as the cohesive soil thicker soil of hard the first day of the lunar month, because the big and centrifugal compression variation of viscosity of clay is big, with the big reaming sleeve of diameter.
The quiet spy injection of deep hole is carried out in the area that runs into the sand thicker soil, because the centrifugal compression variation of sand is little, with the little reaming sleeve of external diameter.
In addition, for obtaining good implementation result, mud pours into the formula reamer when concrete the use, and the diameter of bore of quiet feeler lever will guarantee that mud can be unimpeded smoothly.
Because mud is influential to the intensity of the weak cohesive soil of superficial part, run into the viscous soil horizon of superficial part weakness, use quiet spy pillar soft layer is isolated, with anti-breaking feeler lever.
The configuration requirement of mud is than great, and denseness is big, can produce stable mud skin at hole wall, and it is lubricated that feeler lever and hole wall are produced.
Probe wire must be intact, can not make mud enter the insulativity of probe wire internal influence probe because of the damage of probe wire.
