Abstract
The utility model discloses a land subsidence monitor. The land subsidence monitor comprises a bolt bar (1), a fixing nut (2), a protective cover (3), a magnetic ring (4), a chassis (5) and reserved holes (5.1), wherein the bolt bar (1) is matched with the fixing nut (2) in shape; the lower end of the bolt bar (1) is connected with the chassis (5); the magnetic ring (4) is sleeved on the periphery of the bolt bar (1) and fixed by the fixing nut (2); the protective cover (3) is arranged between the fixing nut (2) and the magnetic ring (4); and the four adapter reserved holes (5.1) are formed in four corners of the chassis (5). Only embedding connecting bolts of subsidence observing points in an early construction stage, the fixation can be directly made by bolts; meanwhile, damage is avoided in the actual construction and convenience is also provided for later maintenance.
Description
Technical field
The utility model relates to a kind of Ground Subsidence Monitoring appearance that ground, soft soil foundation upper strata is carried out long term monitoring.
Background technology
Locate extensively distributing weak soil in that China is riverine, along the lake, coastal etc.; And these areas generally are the developed areas; Along with Chinese Urbanization degree ground improves; Urban land is increasing, encloses to build up fields in sea (lake) and above the soil that forms thereby caused a part of industrial premises to adjourn some outward.The characteristics of soft soil foundation are that natural moisture content is big, void ratio is big, compressibility coefficient is high, intensity is low and have engineering geological properties such as creep properties that engineering geological condition is relatively poor, must take practicable technical measures.For soft soil foundation, what generally take at present is pile foundation based process mode.This mode can both be received good effect for foundation bearing force intensity and settlement request; But the top land subsidence for soft soil foundation causes often is difficult to control; Excessive sedimentation may make ponding Cheng Chi in the place, ground, even causes the cracking destruction of machinery and equipment, crane runway and water, electricity and gas pipe system.
Summary of the invention
In order to overcome prior art problems, the purpose of the utility model is to provide a kind of easy for installation, Ground Subsidence Monitoring appearance that accuracy is high.
For realizing the above object, the technical scheme below the utility model adopts.
A kind of Ground Subsidence Monitoring appearance; Comprise body of bolt, hold-doun nut, over cap, magnet ring, chassis and preformed hole, described body of bolt shape and hold-doun nut match, and the lower end links to each other with the chassis; Described magnet ring is enclosed within the periphery of body of bolt; And fix by hold-doun nut, being provided with over cap between described hold-doun nut and the magnet ring, described chassis is provided with four switching preformed holes for four jiaos.
Design feature and the beneficial effect that the utlity model has are: body of bolt, hold-doun nut, over cap and chassis all are to adopt the stainless steel material preparation, have good antiseptic property, can realize the long term monitoring to land subsidence.The design of preformed hole, it is convenient, flexible to make that the Ground Subsidence Monitoring appearance of the utility model is provided with, as long as at the coupling bolt of pre-buried settlement observation point of construction initial stage, direct bolt just.Simultaneously, avoided in practice of construction, damaging, convenience also is provided for later maintenance.
Description of drawings
Fig. 1 is the structure elevation drawing of the Ground Subsidence Monitoring appearance of the utility model.
Fig. 2 is the structure vertical view of the Ground Subsidence Monitoring appearance of the utility model.
Among Fig. 1-2: 1 body of bolt, 2 hold-doun nuts, 3 over caps, 4 magnet rings, 5 chassis, 5.1 preformed holes.
Embodiment
Further describe below in conjunction with the embodiment of accompanying drawing the utility model.
Shown in Fig. 1-2: a kind of Ground Subsidence Monitoring appearance; Comprise body of bolt 1, hold-doun nut 2, over cap 3, magnet ring 4, chassis 5 and preformed hole 5.1, described body of bolt 1 shape and hold-doun nut 2 match, and the lower end links to each other with chassis 5; Described magnet ring 4 is enclosed within the periphery of body of bolt 1; And fixing by hold-doun nut 2, be provided with over cap 3 between described hold-doun nut 2 and the magnet ring 4, described chassis is provided with four switching preformed holes 5.1 for 5 four jiaos.
Described body of bolt 1, hold-doun nut 2, over cap 3 and chassis 5 all are to adopt the preparation of 304 type stainless steel materials.
Described magnet ring 4 adopts CKJ-88 type sedimentation magnet ring, shell injection molded, interior installation magnetic material.
Claims (1)
