Abstract
The utility model discloses a temporary-central-pillar monitoring device for a foundation pit. The temporary-central-pillar monitoring device for the foundation pit comprises a base and a sliding staff. The base is formed by welding a vertical panel and a convex panel, a slot is formed between the vertical panel and the convex panel, and the sliding staff is inserted in the slot. Two thread holes are formed in the left side of the convex panel, bolts used for fixing the sliding staff are arranged in the two thread holes respectively, and the bottom of the convex panel is further provided with a water drainage hole used for draining water. The device is simple in overall structure and low in cost. A survey crew can carry out measurement only by arranging a level gage for measurement at the position such as a top beam on the edge of the foundation pit, wherein protecting facilities are arranged at the position. Thus, safety of the survey crew is guaranteed practically, measurement accuracy is high, measurement efficiency is high, conditions are provided for informationized construction of excavation of the foundation pit, and construction safety is guaranteed.
Description
Technical field
The utility model relates to a kind of measureing equipment of base pit engineering, especially relates to the interim central post monitoring device of a kind of foundation ditch.
Background technology
Along with the rapid growth of China's economic strength and scientific and technical strength, the application of deep-foundation pit engineering appears at subway engineering, high level, super highrise building engineering, has even been successfully applied to some large bridges.The monitoring project of general deep-foundation pit engineering and scheme are often determined according to ability and the experience of the safe class of foundation ditch, combination construction or monitoring unit, are generally comprised the monolithic stability of foundation ditch, the horizontal distortion of enclosed structure, the water seepage prevention of enclosure wall etc.The processing of monitored data and feedback are also observation data to be done to some simply process, and then incorporation engineering experience is made evaluation to the safe condition of construction stage engineering, and adjusts constructure scheme accordingly.Yet, the vertical displacement of the inner supporting type space enclosing structure central post in deep-foundation pit engineering is controlled and is often often left in the basket, thereby cause space enclosing structure horizontal distortion and periphery formation displacement excessive, affect foundation ditch monolithic stability safety, the serious foundation ditch security incident that even causes.Simultaneously, it is very big that security risk is measured in the interim central post vertical displacement of foundation ditch, because survey crew need to support walking in concrete support or steel, could arrive survey mark, and these all do not have corresponding safeguard procedures on supporting, main cause is, on these support, safeguard procedures high cost is set, because both contradiction causes measuring and cannot complete.
Utility model content
(1) technical problem that will solve
For addressing the above problem, the utility model proposes the interim central post monitoring device of foundation ditch that a kind of survey crew can be measured with level gauge on foundation ditch limit, it is simple in structure, and cost is low, measures efficiency and security performance high.
(2) technical scheme
The interim central post monitoring device of foundation ditch of the present utility model, comprise pedestal and Sopwith staff, described pedestal is welded by facade plate and rased panel, between this facade plate and rased panel, form a slot, above-mentioned Sopwith staff is inserted in this slot, in the left side of rased panel, be provided with two screwed holes, and in two screwed holes, be equipped with for the fixing bolt of Sopwith staff, in the bottom of rased panel, be also provided with a spilled water hole for draining.
Further, described facade plate and rased panel are made by the steel plate of 6mm specification.
Further, the specification of described screwed hole and bolt is M6.
Further, the diameter of described spilled water hole is 8mm.
(3) beneficial effect
Compared with prior art, it has following beneficial effect to the utility model:
The interim central post monitoring device of foundation ditch of the present utility model overall structure is simple, cost is low, survey crew only need be on foundation ditch limit Guan Liang etc. have the measuring level gauge of location arrangements of protective equipment to measure, conscientiously ensured the safety of survey crew, and certainty of measurement is high, measurement efficiency is high, thereby for the information-aided construction of excavation of foundation pit provides condition, guarantees construction safety.

The specific embodiment
The interim central post monitoring device of a kind of foundation ditch as depicted in figs. 1 and 2, comprise pedestal 1 and Sopwith staff 2, described pedestal 1 is welded by facade plate 11 and rased panel 12, between this facade plate 11 and rased panel 12, form a slot 13, above-mentioned Sopwith staff 2 is inserted in this slot 13, in the left side of rased panel 12, be provided with two screwed holes 121, and in two screwed holes 121, be equipped with for the fixing bolt 3 of Sopwith staff 2, the degree of depth by the adjustable Sopwith staff 2 of bolt 3 in slot 13, in the bottom of rased panel 12, be also provided with a spilled water hole 122 for draining, ponding in slot 13 can be discharged, described facade plate 11 and rased panel 12 are made by the steel plate of 6mm specification, described screwed hole 121 is M6 with the specification of bolt 3, the diameter of described spilled water hole 122 is 8mm, during measurement, survey crew only need stand in the location arrangements measurement level gauge that Guan Liang on foundation ditch limit etc. has protective equipment, can measure.
This uses novel mode of occupation one: as shown in Figure 3 when interim central post 4 is side arrangement, in the time of not under concrete support 5, while installing, pedestal 1 is welded on interim central post 4, and be positioned at concrete and support 5 sides, then Sopwith staff 2 is inserted, fixing with bolt 3, and monitoring point should not be less than 10% of the total radical of column, the foundation ditch of reverse construction should not be less than 20%, and should not be less than 5.
This uses novel mode of occupation two: as shown in Figure 4 when interim central post 4 is under concrete support 5, after in construction, the concrete above interim central post 4 supports and pedestal 1 is welded in above interim central post 4 at 5 o'clock together with the Sopwith staff 2 fixing, pour concrete together with supporting 5 with the concrete of its top, with monitoring point described in mode of occupation one, should not be less than 10% of the total radical of column, the foundation ditch of reverse construction should not be less than 20%, and should not be less than 5.
The interim central post monitoring device of foundation ditch of the present utility model overall structure is simple, cost is low, survey crew only need be on foundation ditch limit Guan Liang etc. have the measuring level gauge of location arrangements of protective equipment to measure, conscientiously ensured the safety of survey crew, and certainty of measurement is high, measurement efficiency is high, thereby for the information-aided construction of excavation of foundation pit provides condition, guarantees construction safety.
