Abstract
A kind of foundation pit deformation monitoring nail is made of ailhead, nail body, sponge, cruciate flower and screw thread, and the ailhead passes through the threaded connection of ailhead lower part with nail body, and sponge wrapping, which is lived, follows closely body, and the upper surface of ailhead is recessed cruciate flower.The height of ailhead can prevent monitoring nail from being covered by sundries, since ailhead after the completion of monitoring and nail body can be extracted, to save monitoring material.
Description
Technical field
The utility model relates to deformation of deep excavation to monitor field, in particular to a kind of foundation pit deformation monitoring nail.
Background technique
In deformation of deep excavation monitoring field, the use for monitoring nail is foundation pit deformation monitoring important link, is pouring crown beam
When, monitoring nail is placed in advance in not solidified crown beam, after crown beam concrete setting, passes through the vertical displacement of monitoring monitoring nail
Change with level angle, real-time monitoring is carried out to foundation pit deformation.
The Chinese patent of patent publication No. CN205785221U discloses " a kind of observation nail for measurement ".Of the invention
Technical solution is, including nail lid (1) and rivet nut (2), and the nail lid (1) is set in the top or rivet nut (2) of rivet nut (2)
Portion, be symmetrical arranged on nail lid (1) there are three or four rivet nuts (2), be provided on the nail lid (1) and set for placing to measure
Standby measurement point.
At present when foundation pit deformation monitors, monitoring nail is easily covered by sundries, can not acquire effective monitoring metric data,
Monitoring nail is mostly disposable material, can not be recycled, extremely waste of resource.
Summary of the invention
In order to solve the problems, such as that existing foundation pit deformation monitoring nail is easily capped and waste of material can not recycle, this is practical
It is novel that a kind of foundation pit deformation monitoring nail is provided, it can be ensured that monitoring nail is solid and reliable, can be recycled, and saves monitoring cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
(1) a kind of foundation pit deformation monitoring nail is made of, the ailhead and nail ailhead, nail body, sponge, cruciate flower and screw thread
Body passes through the threaded connection of ailhead lower part, and sponge wrapping, which is lived, follows closely body, and the upper surface of ailhead is recessed cruciate flower.
(2) ailhead top is divided into round pie, and lower part is divided into cylindric and side surface and is furnished with screw thread, and the height of screw thread is nail
The half of cylinder height is divided in head lower part.
(3) nail body is divided into round pie, round pie center hole, has screw thread can be with the spiral shell of part under ailhead in hole
Line is bolted, and nail body middle section is the cylindrical body of middle part indent, and nail body lower part is divided into inverted conical shape.
(4) middle part and lower part of sponge tight nail body, sponge upper end level are higher than the height of ailhead, ailhead and nail body
Material be copper, the material of sponge is polyethers synthetic sponge.
The beneficial effects of the utility model are: ensure that monitoring nail will not since ailhead than crown beam face has more certain altitude
It is covered easily, when monitoring nail is excessively high, ailhead can be removed by rotating screw thread, be directly monitored using nail body, therefore,
Monitoring nail height be it is adjustable, sponge wrapping live follow closely body middle part and lower part, ensure that ailhead and nail body will not be with coagulation
Soil solidification is integrated, and when monitoring is completed, can directly extract ailhead and nail body, carries out that Shanghai can be covered when next monitoring
Silk floss reuses, and saves material.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
The structural schematic diagram of Fig. 1 the utility model.
The ailhead structural schematic diagram of Fig. 2 the utility model.
Fig. 3 the utility model uses schematic diagram.
1. ailhead in figure, 2. nail bodies, 3. sponges, 4. cruciate flowers, 5. screw threads.
Specific embodiment
In Fig. 1, a kind of foundation pit deformation monitoring nail, by ailhead (1), nail body (2), sponge (3), cruciate flower (4) and screw thread
(5) it forms, the ailhead (1) is connect with nail body (2) by the screw thread (5) of ailhead (1) lower part, and sponge (3) wraps nail body
(2), the upper surface of ailhead (1) is recessed cruciate flower (4).Ailhead (1) top is divided into round pie, lower part be divided into it is cylindric, and
And side surface is furnished with screw thread (5), the height of screw thread (5) is the half that cylinder height is divided in ailhead (1) lower part.Follow closely part on body (2)
For round pie, round pie center hole has screw thread (5) that can carry out bolt company with the screw thread (5) of part under ailhead (1) in hole
It connects, nail body (2) middle section is the cylindrical body of middle part indent, and nail body (2) lower part is divided into inverted conical shape.Sponge (3) tight
The middle part and lower part of body (2) are followed closely, sponge (3) upper end level is higher than the height of ailhead (1), and ailhead (1) and the material of nail body (2) are
Copper, the material of sponge (3) are polyethers synthetic sponge (3), when monitoring nail is excessively high, can remove ailhead by rotating screw thread (5)
(1), it is directly monitored using nail body (2).
Claims (4)
1. a kind of foundation pit deformation monitoring nail is made of ailhead, nail body, sponge, cruciate flower and screw thread, it is characterized in that: ailhead and nail
