(5) cheat with the condenser cooling coil arranged of contacting outside groove around being arranged on, and be fixed on side slope surface;
(6) condenser is opened, cooling medium in condenser enters cooling coil, and adjustment regulates condenser, the cooling medium controlled in condenser enters the speed of cooling coil, ground temperature t1 around cooling coil is made to remain on less than 0 DEG C, namely thermometer II reading is less than 0 DEG C, and make jack bottom rock-soil temperature remain on more than 0 DEG C, namely thermometer I reading is greater than 0 DEG C;
(7) test of side slope anchor rod drawing is carried out.
Further, also step a is comprised between step (2) and (3): between jack and hole groove, place backing plate.
Further, the hole groove depth dug in step (1) is 20-30cm.
Further, the hole groove dug in step (1) is rectangle hole, and digging width is 20cm.
Further, the hole groove dug in step (1) is cylindrical recess, and digging diameter is 20cm.
Further, also step b is comprised between step (1) and (2): be wrapped in thermal insulation material by jack.
Beneficial effect of the present invention is:
Utilize jack fixing means of the present invention, not only make jack stable be fixed in side slope, ensure that simultaneously the deadweight of jack can not act on to anchor pole produce eccentric force, ensure that the accuracy of experimental data; Meanwhile, utilize the method for cooling ground and filling mud that geotechnical stability around jack is increased, what jack was more stable is fixed in side slope, improves the accuracy of result of the test.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by manual below and obtain.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is embodiment of the present invention schematic diagram;
Fig. 2 is the connected mode schematic diagram of condenser coil and condenser in Fig. 1.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, the preferred embodiment of invention is described in detail.Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
As shown in Figure 1 and Figure 2, the jack fixing means for the test of side slope anchor rod drawing of the present embodiment, comprises the following steps:
(1) in side slope, dig hole groove 5, ensure that groove 5 bottom surface, hole is vertical with anchor pole 1, side is parallel with anchor pole 1, for the placement of jack provides position, and provides condition for guarantee jack centre bore does not contact with anchor pole;
(2) by the centre bore of anchor pole 1 through jack 4, and jack 4 is placed in the groove 5 of hole;
(3) regulate jack 4 position, ensure that jack 4 centre bore axis is parallel with anchor pole 1 and do not contact, making jack 4 can not produce eccentric force to anchor pole, now, between hole groove 5 and jack 4, fill up mud, form mud layer 8, jack 4 is fixed in the groove 5 of hole.In the groove of hole, fill up mud can not only make the side wall strength of hole groove 5 increase, and jack 4 can also be made to be fixed on completely in the groove 5 of hole simultaneously.
(4) will be used for measuring the thermometer I 10 of jack 4 bottom rock-soil temperature through the mud layer 8 hole groove 5 and jack 4, make thermometer I 10 end and cheat groove 5 bottom surface and contact; Thermometer II 9 end being used for measuring hole groove 5 surrounding mantle rock soil temperature degree is imbedded in the side slope top layer ground around the groove 5 of hole;
(5) cheat with condenser 11 cooler pan 3 pipe ring arranged of contacting outside groove 5 around being arranged on, and be fixed on side slope surface;
(6) condenser 11 is opened, cooling medium in condenser 11 enters cooling coil 3 by the outlet on condenser 11, then condenser is recovered to by the entrance of condenser 11, adjust and regulate condenser 11, the cooling medium controlled in condenser 11 enters the speed of cooling coil 3, and make ground temperature t1 around cooling coil remain on less than 0 DEG C, namely thermometer II 9 reading is less than 0 DEG C, ensure that jack 4 bottom rock-soil temperature remains on more than 0 DEG C, namely thermometer I 10 reading is greater than 0 DEG C.Ensure that hole groove 5 surrounding ground forms frozen soil layer 2, and mud layer is hardened, hardness improves, and meanwhile, avoids jack 4 bottom rock-soil (i.e. anchor pole 1 surrounding ground) geology Yin Wendu and reduces and change.
(7) test of side slope anchor rod drawing is carried out.
In the present embodiment, the hole groove 5 dug in step (1) is rectangle hole, and digging width is 20cm, digging the degree of depth is 25cm, makes the space of cheating groove 5 be large enough to hold jack 4, simultaneously, the degree of depth of the hole groove 5 dug is enough shallow, can not affect the accuracy of pull-out test result.
As the improvement of the present embodiment, after completing steps (2), before jack 4 and hole groove 5, place one piece of backing plate 7, then carrying out step (3).Place backing plate 7, the deadweight of jack 4 is first acted on backing plate, is then being delivered to uniformly on mud layer 8, make mud layer 8 stressed evenly, structure is more stable, also just make hole groove more stable.
As the improvement of the present embodiment, after hole groove in completing steps (1) digs, jack 4 asbestos 6 are wrapped up in, be placed in the groove 5 of hole again, the low temperature around by cooling coil 3 is avoided to be delivered to jack 4 inner, thus avoid the inner fluid condensation of jack 4, the accuracy of guarantee test result.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
