Description
Technical field
The utility model relates to the construction of railways field, is specially a kind of subgrade settlement deformation observation device.
Background technology
High-speed railway has now become the preferably selection that many countries solve trip communications and transportation problem.China is vast in territory, populous, the high-speed railway of China is established development rapidly, the construction of high-speed railway has far-reaching influence to the economic construction of China, recent years, China has built up Beijing-Shanghai express railway, the military wide visitor high-speed railway with high technology content such as special, the soft soil roadbed excessively probability of its link tester is bigger, because the compressibility height of soft soil foundation, natural moisture content are big, poor permeability, consolidation deformation longer duration, so the settlement after construction of roadbed is all most important in work progress, construction later stage and later stage observation, affect the operation in railway later stage.
For the ride comfort and stability that guarantees high-speed railway, standard is very strict to the sedimentation and deformation control of roadbed, except taking the rational and effective method for processing foundation, guaranteeing the construction quality, must carry out the sedimentation and deformation monitoring in the construction, and then according to deformation measurement data, take rational Forecasting Methodology, predict contingent settlement after construction, instruct squeeze time and definite ballastless track structure construction according to predicting the outcome and lay a railway track the time.Therefore, the sedimentation and deformation accuracy of observation of high-speed railway subgrade section is the key factor that concerns the long-term operation security of high ferro and comfortableness.
At present, the observation of subgrade engineering sedimentation and deformation is observed the master with road bed settlement observation and settlement of foundation, mainly concrete conditions such as the structure position that designs with drawing, embankment height, foundation condition, piling prepressing arrange the sedimentation and deformation measuring frequency section, should or set up measuring frequency section according to the landform of grasping in the work progress, the adjustment of geology situation of change simultaneously.General embankment location measuring frequency section comprises settlement observation stake and settlement plate, and the every section of settlement plate arranges 1, is arranged in two-wire roadbed center, and the every section of settlement observation stake arranges 3, is arranged in two-wire roadbed center and both sides, line center, the left and right sides.Yet, owing to arrange so intensive settlement plate on the roadbed, paving of roadbed brought great inconvenience with the compacting construction, big machinery construction simultaneously destroys serious to settlement plate, repeatedly spot check finds have more than half settlement plates to meet with destruction in work progress, and this has directly influenced the precision of settlement observation, in addition, existing settlement plate complex structural designs, execute-in-place inconvenience, cost height are unfavorable for promoting on a large scale.
Summary of the invention
The utility model for solve existing subgrade settlement deformation observation with settlement plate in construction, destroy seriously, problems such as complex structure, operation inconvenience and cost height, a kind of subgrade settlement deformation observation device is provided.
The utility model is to adopt following technical scheme to realize: subgrade settlement deformation observation device; comprise the sedimentation base plate; the protective casing that is fixed on the measuring staff on the sedimentation base plate and is sleeved on the measuring staff outside; innovative point of the present utility model is that measuring staff is flexibly connected from beginning to end piecemeal and made by the metal hollow pipe; adopt nipple to connect between the adjacent segment metal hollow pipe; protective casing is flexibly connected from beginning to end piecemeal and is made by nonmetal hollow tubular; adopt coupling to connect between the nonmetal hollow tubular of adjacent segment; wherein the protective casing mouth of pipe is lower than the measuring staff mouth of pipe, and the protective casing mouth of pipe is provided with gland bonnet.Described nipple and coupling are existing known features, can adopt multiple version to realize.
Described every section metal hollow length of tube is 50mm, can satisfy the spreading requirement, and it is longer to avoid again elevating above the soil, and influences the working-yard normal construction.
Adopt structural design of the present utility model, measure and bury settlement plate measuring staff masthead absolute altitude reading in place underground as initial reading, along with the roadbed filling construction connects high measuring staff and protective casing gradually, spreading fore-and-aft survey masthead absolute altitude variable quantity determines to connect a large amount.
Compared with prior art; protective casing described in the utility model is in the outside of measuring staff; and set up gland bonnet at the top; for measuring staff provides a cavity freely; make settlement plate in the subgrade construction process, be in and the contactless state of subgrade soil; effectively avoided in the work progress damage to measuring staff; the utility model is simple in structure; reasonable in design; cost of manufacture is lower; and connected mode is simple and reliable; the working-yard is easy and simple to handle, has guaranteed the minimum influence to surrounding environment, has guaranteed construction quality; improve construction speed, had certain popularization value and using value.
