Description
Technical Field
The utility model relates to an anchor rope detection area, the more specifically detection device of recoverable pressure dispersion type anchor rope that says so.
Background
The foundation pit supporting anchor cable is mainly used in the foundation pit supporting stage, and ensures that the foundation pit has enough anchoring force to resist the active soil pressure borne by the foundation pit and not collapse inwards.
The common anchor cable mainly obtains the withdrawal resistance through the bonding between anchor section anchor cable and the grouting body, but the bonding stress of common anchor cable on anchoring length distributes unevenly, leads to the bonding stress concentration in anchor section near-end easily, is unfavorable for the performance of the work efficiency of anchor cable, and in case a certain anchor cable destroys probably leads to whole hole anchor cable to destroy the inefficacy, and in case ordinary anchor cable in case the construction even the anchor cable is no longer exerted the efficiency but can't retrieve after the support period finishes, causes certain wasting of resources.
The working principle of the hot-melting recoverable pressure dispersion anchor cable commonly used at present is that prestress is dispersed and acted on different depths of a rock-soil body through a plurality of unbonded steel stranded wires with different lengths and a steel bearing body to form a multi-section anchoring unit, so that the stress concentration phenomenon is avoided. The anchor cable is characterized in that after the supporting engineering is completed, the supporting anchor cable can be connected with a 36V low-voltage power supply through an electric heating ring buried on the anchor head of the anchor cable and an embedded wire in an external mode step by step according to the construction progress, the electric heating ring on the anchor head is heated after the electric heating ring is powered on to melt the lining of the anchor head, the anchoring effect is removed, and then a small-sized recovery machine is used for clamping the anchor cable to be pulled out, so that the anchor cable body can be pulled out, and the recovery purpose is achieved. The subway construction unit in the urban center area generally initiates a claim to the original anchor cable construction unit in the process of certain danger and operation difficulty. In summary, the recoverable pressure dispersion type anchor cable is safer in structure, can be recycled, and is particularly suitable for subway construction areas possibly existing in urban central areas in the future.
The recoverable pressure dispersion type anchor cable is a novel anchor cable supporting technology, the existing detection standard only specifies that unit anchor rods are adopted for group-by-group tensioning detection or parallel jacks are used for synchronous tensioning detection when the pressure dispersion type anchor cable is detected, but the detection standard does not specify a detection device of the pressure dispersion type anchor cable. When the group-by-group tensioning method is adopted for detection, the pressure dispersion type anchor cable generally adopts a structure of 2 groups or 3 groups of stress units, the detection method needs to sequentially detect each anchor cable stress unit, the detection time is 2-3 times or even longer than that of the common anchor cable, and the control of the construction period is not facilitated. The method for synchronously tensioning and detecting the parallel jacks is adopted, namely the jacks with the same number as the anchor cables are adopted to synchronously apply load detection to each anchor cable, the method can ensure that the load borne by each anchor cable is the same, the problem that the load of the jacks for detecting each anchor cable is not uniformly distributed when only one jack is adopted for detection is solved, the detection time is basically the same as that of a common anchor cable, but the method still has the following problems:
one, parallelly connected jack detects, if adopt a jack to correspond a pressurized oil pump, then detect four muscle anchor ropes and need be equipped with 4 oil pumps, every oil pump needs to be equipped with a inspector, and required personnel are more than 2 times of ordinary detection, and the synchronous pressurized speed of different oil pumps is difficult to guarantee unanimously, does not accomplish completely synchronous effect.
Secondly, the anchor cables are close to each other when penetrating out of the waist beam, the jacks used for detection can be put down only by dispersing the anchor cables when the parallel jacks are adopted for synchronous tensioning detection, and how to reasonably separate the anchor cables to achieve a detectable state is very important.
And thirdly, in the detection process, the displacement of the anchor cable changes along with the loading of the jack, so that how to accurately measure the change of the displacement can be realized, and the quality of the anchor cable can be correctly evaluated.

A detection method of a recoverable pressure dispersion type anchor cable adopts the detection device of the recoverable pressure dispersion type anchor cable for detection, and comprises the following specific steps:
the first step is as follows: the anchor cable 200 to be detected passes through the dispersive anchor cable guider 1;
the second step is that: the jack 25 is arranged on the dispersive anchor cable guider 1 and is connected with the oil pressure sub-controller 22 and the oil pump 21;
the third step: starting the oil pump 21, locking the anchor cable 200 to be detected by the jack 25, and then closing the oil pump 21;
the fourth step: fixing the displacement measuring mechanism 3, and enabling a second magnetic gauge stand 33 on the displacement measuring mechanism 3 to be adsorbed on the anchor cable 200 to be detected;

Specifically, since the plurality of anchor lines 200 to be tested are in a close-packed state, the dispersion type anchor line guide 1 is required to disperse them. The jack 25 is arranged on the dispersive anchor cable guider 1 and connected with the oil pressure branch controller 22 and the oil pump 21, at the moment, the oil pump 21 should be started, the pressure jack 25 pushes the built-in locking plate at the front end to be self-locked under the action of oil pressure, the anchor cable 200 to be detected is locked, the situation that the locking tightness of the anchor cable 200 to be detected is different can occur in the process, the problem is generally caused by the fact that the adjusting switch 223 of the oil pressure branch controller 22 is different, the adjusting switch 223 corresponding to the tighter anchor cable 200 to be detected can be screwed, then the oil pump 21 is started to pressurize, at the moment, the anchor cable 200 to be detected which is locked looser is pressurized, and the state to be detected can be quickly locked (it needs to be explained that the displacement change of the anchor cable 200 to be detected in the adjusting process is very large, and the displacement is not required displacement data, so that the displacement data before locking is not required to be measured). Then, the reference frame 31 is driven into the soil to be fixed, the zero key is pressed to zero after the displacement sensor 35 is installed, the detection state is reached, the oil pump 21 is started again, and the recording of displacement data can be started.
Because whole structural design is ingenious, need not many people and assists during the detection, has saved the manpower, and the displacement measurement mechanism 3 of design moreover, the atress subsection is reasonable, is in quiescent condition all the time in the testing process, can effectively guarantee the degree of accuracy of waiting to examine anchor rope 200 displacement changes that record, has guaranteed to detect reasonable degree of accuracy.
