Abstract
The present invention relates to the automatic monitoring method for cement-soil stirring pile construction. The present invention has headway, flow rate, density and rotation sensors the collect signals, transmits the signals via antenna or copies the signals via movable memory to computer, and records and processes the signals and data in the computer with proper software. The present invention is one kind of positive real-time dynamic monitoring method and may be used in continuous monitoring of pile construction and real-time analysis of foundation soil strength and other characteristics to avoid artificial engineering quality problem. The monitoring apparatus has small size, convenient carrying about and simple use.
Description
Technical field
The present invention relates to a kind of automatic monitoring method for cement-soil stirring pile construction, particularly a kind of real-time automatic monitoring method.
Background technology
Cement mixing method (comprising slurry spray stake and powder spray piling) is to utilize special Mixing Machine to be pressed into cement grout or powder in the soil body and stir, a kind of pile foundation technology that forms by a series of physical-chemical reactions.Compare with other construction technologies, because advantage such as low, the easy construction of its cost and in ground stabilizations such as speedway and Industrial and Civil Engineering, being applied.But carry out in the work progress utilizing this technology, because artificial factor causes workmanship and progress wayward and be difficult to management etc., for example in the work progress because project supervision side can't carry out real-time oversight to the construction of construction party whenever and wherever possible, thereby occur the pile sinking degree of depth not in place, dust or the inhomogeneous or discontinuous phenomenon of whitewashing amount, make engineering not reach the purpose of design, cause its enforcement of some territorial restrictions thus and influenced applying of this technology.In addition, because the disguise and the skewness of underground construction, can not in time find the soil behaviour of underground soil layer at work progress, can't time update design and working measure, this has also influenced applying of this technology.
The underground construction quality examination is difficulty relatively, and quality examination at present mainly is core boring sampling, low deformation dynamic inspection etc., and is toposcopy, and these all are passive afterwards detection methods, are passive inspections.How can initiatively carry out the quality ACTIVE CONTROL in construction is the problem that the researcher explored always.In recent years, along with computing power improves, the mobile storage capacity increases and the popularizing and using of the development, particularly wireless network transmission technology of sensor technology, for real-time automatic monitoring and monitoring provide may and condition.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, studies a kind of new cement-soil stirring pile construction real-time automatic monitoring method.
Technical scheme of the present invention:
A kind of automatic monitoring method for cement-soil stirring pile construction has cement-soil mixing pile machine, comprises frame, vibration head, shaft, feed pipe for mortar, stirring-head, and its major technique is characterised in that:
(1) adopt drilling depth sensor, flow transmitter, density sensor, turn-sensitive device to gather power signal.
(2) drilling depth sensor, flow transmitter, density sensor, turn-sensitive device are installed on the frame, and wherein the drilling depth sensor is arranged on the vibration head top, and flow transmitter and density sensor are arranged on the feed pipe for mortar, and turn-sensitive device is arranged on the shaft.
(3) signal with drilling depth sensor, flow transmitter, density sensor, turn-sensitive device is transferred in the data acquisition unit by signal cable respectively, and the data of gathering are sent to network computer, or copy in the computer by mobile memory by the antenna on the data acquisition unit.
(4) computer carries out real time record, processing with various data by software.
Advantage of the present invention and effect: this be a kind of complete initiative, in advance with the monitoring method of dynamic real-time, can automatically, objectively and continuously write down and monitor the cement-soil stirring pile construction all processes, can carry out strange land monitoring to the side of management, stop that construction party such as uses inferior materials and turns out substandard goods at human factor and the qualitative problems of construction that causes.The data that collect are analyzed, can be in real time or the dynamic chek work progress, can further check the quality of pile body.The data that collect are analyzed, can also be analyzed the characteristics such as intensity of foundation soil body.Flow transmitter, density sensor, drilling depth sensor, turn-sensitive device and on-the-spot portable data collector can be integrated into product and produce in batches in factory, easy to carry, use simply effective.
Description of drawings
Fig. 1---real-time automatic monitoring principle of device schematic diagram of the present invention.
Fig. 2---figure is implemented in real-time automatic monitoring construction of the present invention.
The specific embodiment
As shown in Figure 1, 2, at first drilling depth sensor 2, flow transmitter 3, density sensor 4, turn-sensitive device 5 are fixed on the cement-soil mixing pile machine frame 9.Wherein drilling depth sensor 2 is arranged on the top of vibration head 10, advances the degree of depth of stake with real time record; Flow transmitter 3 and density sensor 4 are arranged in defeated slurry (powder) pipe 12, with the density of defeated slurry amount of real time record and defeated slurry (powder); And turn-sensitive device 5 is arranged on the shaft 11 of below of vibration head 10, with the rotation of real time record shaft 11, reflects underground soil characteristics; The above-mentioned signal that collects is connected on the portable data collector 1 by signal cable 6 respectively; Data acquisition unit 1 is connected with antenna 7, and the top that antenna 7 is arranged on the frame 9 of cement mixing method is the best.
After coming into effect, under vibration head 10 effects, shaft 11 begins to stir, cement grout or powder import stirring-head 13 into by defeated slurry (powder) pipe 12 and mix stirring with soil, drilling depth sensor 2, flow transmitter 3, density sensor 4, turn-sensitive device 5 grades are with automatic recorded information and be transferred in the portable data collector 1, transfer signals in the network computer 8 by transmitting antenna 7, if without antenna 7 emissions, also can be copied in the computer 8 with mobile memory, data in the network computer 8 are carried out analyzing and processing, and set up record data and on-the-spot soil condition, various corresponding relations such as pile body parameter are with the purpose of the quality that reaches the real-time automatic monitoring cement mixing method.
Can drilling depth sensor 2, flow transmitter 3, density sensor 4, turn-sensitive device 5 can be used in combination according to practice of construction needs and requirement, or all or part of.
