Abstract
The utility model discloses an apparatus for detecting a soil extruding force of an existing construction structure in composite shield tunneling. The apparatus comprises multiple concrete strain gauges arranged at the same monitoring fracture plane, wherein the monitoring fracture plane is vertical to the axis of a construction tunnel, and the multiple concrete strain gauges are arranged at intervals and form a circular ring. According to the utility model, the multiple concrete strain gauges are arranged at the same monitoring fracture plane so that comprehensive detection of the soil extruding force in a shield construction process can be realized, thus the soil change in the construction process can be best reflected, and the construction safety can be ensured.
Description
Technical field
The utility model relates to subway work servicing unit field, relates in particular and under a kind of composite shield, wears existing construction of structures soil body extruding force pick-up unit.
Background technology
In the project under construction of Changsha subway, interval work progress between cultural art center station to eastern station, Mei Xi lake specifically, due to engineering Sui Zhi district country rock mainly by silty clay, severely-weathered slate, in wind slap, middle weathering glutenite and micro-wind slap etc. form, and in on-site slate, be mingled with softer argillaceous slate, so making country rock soft or hard inequality and geology separatrix uneven is a large feature of its above-mentioned engineering geology, under the uneven condition of geology, how effectively to control shield tunneling, guaranteeing construction safety, is a great problem of puzzlement construction.
For an above-mentioned difficult problem, the applicant concentrates on studies, and by soil body extruding force pick-up unit is set, thereby soil body extruding force in shield-tunneling construction process is rationally detected, and for the construction of Subway Tunnel provides parameter accurately, instructs.
Utility model content
The purpose of this utility model is to provide wears existing construction of structures soil body extruding force pick-up unit under a kind of composite shield, with detect shield structure when the construction Subway Tunnel near the extruding force of the soil body.
In order to reach above-mentioned purpose, solution of the present utility model is:
Under composite shield, wear existing construction of structures soil body extruding force pick-up unit, wherein, comprise a plurality of concrete strain gauges that are laid on same monitoring section, this monitoring section is perpendicular to construction tunnel axis, and the plurality of concrete strain gauge interval arranges and is one circular.
Further, this monitoring section same position place respectively arranges respectively a concrete strain gauge in interior outside.
Further, the plurality of concrete strain gauge is laid in the vault of monitoring section, upper and lower spandrel, haunch and inverted arch position.
Further, the plurality of concrete strain gauge is fixed on the main muscle of interior reinforcing bar of prefabricated pipe section.
Further, the plurality of concrete strain gauge extends along wall tangential direction.
Adopt after said structure, under the composite shield that the utility model relates to, wear existing construction of structures soil body extruding force pick-up unit, it by being provided with a plurality of concrete strain gauges on same monitoring section, so can be so that soil body extruding force be comprehensively detected in shield-tunneling construction process, thereby the soil body reflecting best in work progress changes, and reaches the effect of guaranteeing safe construction.
Accompanying drawing explanation
Fig. 1 is the artwork that the utility model relates to a plurality of concrete strain gauges in soil body extruding force pick-up unit;
Fig. 2 is that the utility model relates to a plurality of concrete strain gauges in soil body extruding force pick-up unit and is arranged on two schematic diagram during shield-tunneling construction side by side.
In figure:
Radius R.
Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
As shown in Figure 1, under a kind of composite shield that the utility model relates to, wear existing construction of structures soil body extruding force pick-up unit, comprise a plurality of concrete strain gauges 1 that are laid on same monitoring section 3, this monitoring section 3 is perpendicular to construction tunnel axis 2, and the plurality of concrete strain gauge 1 interval arranges and is one circular.More preferably, as shown in Figure 1, these monitoring section 3 same position places respectively arrange respectively a concrete strain gauge 1 in interior outside.
In the present embodiment, the plurality of concrete strain gauge 1 is laid in the vault of monitoring section 3, upper and lower spandrel, haunch and inverted arch position, to realize omnibearing soil body extruding force, detects.As a kind of fixed form of a plurality of concrete strain gauges 1, the plurality of concrete strain gauge 1 is fixed on the main muscle of interior reinforcing bar of prefabricated pipe section.In addition, the plurality of concrete strain gauge 1 preferably extends along wall tangential direction.
As shown in Figure 2, the layout of the pick-up unit while wherein showing two shield-tunneling construction side by side, it is also laid with a plurality of concrete strain gauges 1, its middle at two construction tunnel axis 2 is provided with concrete strain gauge 1, then the arranged outside separately at two construction tunnel axis 2 has concrete strain gauge 1, particularly, in Fig. 2, the outside of each construction tunnel axis 2 is all provided with 2 concrete strain gauges 1, these 2 concrete strain gauges 1 are positioned at outside Tunnel-hole, be that distance L 1 and L2 between these 2 concrete strain gauges 1 and construction tunnel axis 2 is greater than Tunnel-hole radius R, to play to improve, detect comprehensive effect, similarly, the top of each construction tunnel axis 2 is all provided with a concrete strain gauge 1.
Like this, under the composite shield that the utility model relates to, wear existing construction of structures soil body extruding force pick-up unit, it by being provided with a plurality of concrete strain gauges 1 on same monitoring section 3, so can be so that soil body extruding force be comprehensively detected in shield-tunneling construction process, thereby the soil body reflecting best in work progress changes, and reaches the effect of guaranteeing safe construction.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
