Description
Technical field
The utility model relates to the ground anchorage of the quiet spy equipment of a kind of formula of casting anchor, and is mainly applicable to rigid pavement, city and marble road surface.
Background technology
Along with the development of economy, the urbanization process of China is also progressively being accelerated, and the living standard of people improves constantly, city size constantly expands, urban population sharply increases, and the height of resident trip and the interflow of commodities is frequent, and urban traffic is faced with severe situation.Thus along with China's urban modernization, process of industrialization, this power of subway greatly, does not take the traffic transporting facility of ground space, just quietly rises in the construction of big and medium-sized cities, and becomes the optimal selection solving urban transport problems.
The construction of subway engineering is that traditional engineering investigation industry brings new opportunity, cone penetration test is widely adopted as a kind of full-fledged soil engineering in-situ test technology, and engineering investigation static cone penetration equipment in the past large for existing urban road damage area, test length consuming time, to repair difficulty large, thus the urban traffic that this has blocked up be can't bear the heavy load more.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing provide a kind of fast, operate simple and easy, original municipal ground to be destroyed to the quiet spy equipment of formula of casting anchor that is little and that easily repair ground anchorage, make civilization, the experimental technique of specialty become the new foothold of enterprise and developing direction.
The technical scheme that the utility model adopts is: the ground anchorage of the quiet spy equipment of a kind of formula of casting anchor, it is characterized in that: this ground anchorage comprises the plant bottom case of two parallel longitudinal settings, at welding two groups of bearings of this plant bottom case two ends lateral symmetry, often organize bearing to be parallel to each other by two and the channel-section steel that space is left in centre forms, adaptive screw rod in described space, screw rod upper end is screwed on the upper surface of bearing through disc, and screw rod lower end connects expansion bolt by deformable joints.
Described screw rod has 6, and layout 3 on every collateral seat, one of them is positioned in the middle of two root device bases, and two other is symmetrically set in outside plant bottom case.
The beneficial effects of the utility model are: the utility model is equivalent to provide a counter-force platform, when concrete thickness meets the demands, the counter-force required for test is provided by the expansion bolt arranged, screw rod can be removed rapidly after off-test and connect deformable joints, equipment entrucking is gone to position, next hole, the hole that stays after hole for the expansion bolt and test all job mix cement mortar can be carried out to sealing of hole and fills and leads up, consumption is little, consuming time short, operate simple and easy, easy reparation, little on traffic circulation impact, improve development and the quality of city track traffic engineering prospecting, meet the requirement of civilized construction in municipal prospecting process.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the ground anchorage of the present embodiment is equivalent to a counter-force platform, utilizes the frictional force between expansion bolt 6 and material to provide test counter-force, carries out static sounding operation on the platform.This ground anchorage is made up of two groups of bearings 4 that two parallel longitudinal plant bottom cases 5 are parallel with welding transverse direction on the base, forms the counter-force platform of groined type.Often organize the upper surface (two ends near plant bottom case) being welded on plant bottom case 5 that bearing 4 is parallel to each other by two channel-section steels, gap is left between two channel-section steels, screw rod 3 (described gap should slightly larger than screw diameter) is furnished with in this gap, bearing 4 upper surface is fixed on by tapped disc 2 in the upper end of screw rod, and the lower end of screw rod connects a deformable joints 1, the other end of deformable joints is threaded expansion bolt 6.
In order to transversely both sides provide counter-force symmetrically, this routine screw rod has 6, and every collateral seat 4 arranges 3, and one of them screw rod is positioned at the centre of two root device bases 5, and two other screw rod is symmetrically set in outside plant bottom case.
In the present embodiment the key dimension of each parts and annexation as follows:
Deformable joints 1 entirety is long is 6cm, and inner logical threading, upper and lower side is connecting screw rod 3 and expansion bolt 6 respectively.
Disc 2 external diameter is about 10cm, internal diameter size is consistent with screw rod 3 external diameter, for screw rod 3 is fixed on bearing 4.
Screw rod 3 external diameter is about 22mm, length 50cm, and upper end utilizes disc 2 to be fixed on bearing 4, and bottom and deformable joints 1 are threaded connection.
The long 1500mm of bearing 4, wide is be reserved with the gap being greater than screw rod 3 diameter in the middle of 1100mm, and static cone penetration equipment is positioned over above bearing 4, and is stable at ground by six screw rods.
The bolt model of expansion bolt 6 is M16 × 200, and its specification is long 20cm, diameter is Φ 22mm, and permission maximum pull is 1940kg, maximum shear 1440kg; Expansion bolt utilizes to take along shape gradient to impel to expand produce friction bond stress and reach fixed effect.
The operating procedure of the present embodiment is as follows:
A, set static cone penetration equipment according to test hole position, and determine the position of 6 hole for the expansion bolts.
B, first use electric impact drill (hammer) on concrete or marble road surface, open the hole of corresponding size, hole depth should 5 millimeter darker in the length of expansion tube, then in bolt, expansion tube load hole, abundant tightening nut.
C, screw rod 3 is screwed in deformable joints 1 form entirety, this joint lower end connects the nut of expansion bolt 6, checks junction quality, guarantees reliable.
D, by screw rod 3 through behind the gap of bearing 4, screw in disc 2 to bearing 4 from top, and reserved certain space.
E, set gradually remaining five screw rod 3 as stated above, tighten fixing entirely anchor device successively.
F, conveniently method of operating connect the spy equipment that is fond of tranquility, and measurement obtains data.
After j, DATA REASONING, remove disc 2, screw rod 3, deformable joints 1 successively, fill up road surface with cement paste.
H, the end of job.
