Description
Technical Field
[0001] The utility model relates to the technical field of instrument comparison and measurement equipment, in particular to an underground vibration isolation and waterproof instrument pier structure. Background Technique
[0002] An instrument pier is a working platform that combines instrument comparison and measurement with observation, and is used to collect ground vibration signals. Therefore, it has strict requirements for anti-vibration interference. During construction, it is required that the concrete pier and the building main body cannot have a rigid connection, that is, to ensure that there is enough gap between the pier and the building main body to form a vibration isolation groove to ensure that there is no external disturbance in the horizontal direction; in addition, the settlement of the instrument pier should also be strictly controlled in the vertical direction, that is, it is required that the pier is located on stable bedrock. At present, fissure water generally exists in underground rock masses, especially during the high water period, which causes the fissure water to leak into the vibration isolation groove and overflow from the top of the vibration isolation groove, thus affecting the accuracy of instrument comparison and measurement and observation experiments, and even threatening the safety of the entire working platform. The existing conventional construction methods mostly adopt drainage schemes to drain the seepage water in the vibration isolation groove, but this method will generate great vibration and have a greater impact on instrument comparison and measurement and observation experiments, and at the same time, the operation cost is relatively high. Content of the Utility Model
[0003] The purpose of the utility model is to provide an underground vibration isolation and waterproof instrument pier structure to solve the problem that the fissure water in the bedrock penetrates into the vibration isolation groove in the prior art and affects the instrument comparison and measurement and observation experiments.
[0004] To solve the above problems, the technical solution of the utility model is: an underground vibration isolation and waterproof instrument pier structure, including an instrument pier body, a building structure body, a drainage ditch, a vibration isolation groove, a vibration isolation filling layer, a waterproof protection layer, a middle embedded waterstop, a waterproof rubber, an external pasted waterstop, an additional waterproof layer, and a bedrock surface;
[0005] The drainage ditch is communicated with the top of the vibration isolation groove and is used to drain water in time when there is water to protect the instrument pier and equipment; the instrument pier body is separated from the building body to form a vibration isolation groove and is filled with a vibration isolation filling layer; the waterproof protection layer is arranged in the vibration isolation groove and is located on the upper and lower sides of the middle waterstop; one end of the middle embedded waterstop is pre-installed on the instrument pier body, and one end is pre-installed in the building structure body; one end of the external pasted waterstop is pre-installed on the joint surface between the instrument pier and the bedrock, and one end is pre-installed on the joint surface between the building structure body and the bedrock, and is used to make the external pasted waterstop stick tighter when there is water pressure; the additional waterproof layer is provided with a foam plastic rod and a waterproof coiled material to protect the external pasted waterstop.
[0006] The vibration isolation groove is arranged around the pier and is used for isolation from the building body;
[0007] The drainage ditch is communicated with a sump, and the sump drains water to the outside through an automatic water pump.
[0008] The embedded waterstop is connected to the building body and the instrument pier through embedded casting.
[0009] One end of the external pasted waterstop fixed at the bottom of the instrument pier and within the joint surface with the bedrock is the folded end. One end of the external pasted waterstop extends into the joint surface between the bottom of the instrument pier and the bedrock and then folds, and extends out of the joint surface between the bottom of the instrument pier and the bedrock in the reverse direction.
[0010] After the external pasted waterstop folds and extends out of the joint surface between the bottom of the instrument pier and the bedrock, it continues to extend in the reverse direction along the pasted position of the external pasted waterstop to the joint surface between the building body structure and the bedrock.
[0011] The additional waterproof layer extending out of the joint surface between the bottom of the instrument pier and the bedrock after folding continues to extend in the reverse direction along the original joint surface position between the bottom of the instrument pier and the bedrock into the joint surface between the building body structure and the bedrock.
[0012] Furthermore, the additional waterproof layer is a waterproof coiled material and a foam plastic rod.
[0013] Furthermore, the additional waterproof layer can protect the external pasted waterproof coiled material from being damaged by external forces, and at the same time further enhance the waterproof performance;
[0014] A foam plastic rod is arranged perpendicular to the folding part of the waterproof coiled material between the external pasted waterstop and the waterproof coiled material, for strengthening the fitting between the external pasted waterstop and the side wall of the instrument pier and the top surface of the bedrock.
[0015] Furthermore, the plastic rod is a foam plastic rod
[0016] The seismic isolation filling layer is fine sand.
[0017] The waterproof protective layer is sealed with polyurethane sealant and filled with polystyrene board.
[0018] The technical effects of the present utility model are mainly reflected in: a three-layer waterproof system is formed through the cooperation between the drainage ditch, the embedded waterstop and the external waterproof waterstop. Among them, the embedded waterstop blocks the seismic isolation groove through the embedded waterstop, preventing the seepage water in the seismic isolation groove from overflowing upwards continuously. The waterproof protective layer also protects the embedded waterstop. Among them, the external waterproof waterstop blocks the fissure water in the bedrock through the external waterproof waterstop, preventing water from penetrating into the seismic isolation groove. The additional waterproof protective layer also protects the external embedded waterstop. Cooperating with the drainage ditch, a three-layer waterproof effect is achieved, ensuring the safety of the working platform and the accuracy of the instrument comparison and observation experimental data.

[0025] In the specific embodiments, if the connection or fixing manner between components is not specifically stated, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0026] The present utility model provides a seismic isolation and waterproof observation pier structure, as Figures 1-3 shown, including 1 - Finished building surface, 2 - Drainage ditch, 3 - Asphalt joint cover, 4 - Seismic isolation groove, 5 - Instrument pier, 6 - Fine sand, 7 - Building structure body, 8 - Bedrock.
[0027] A gap is left between the instrument pier body 5 and the building structure body 7 to form a seismic isolation groove 4. Fine sand 6 is arranged in the seismic isolation groove 4, and an asphalt joint cover is arranged at the top of the seismic isolation groove 4. Below the building finish surface 1 and above the building body structure is a drainage ditch 2, which is connected to the seismic isolation groove to play an emergency drainage role and form the first waterproof measure. One end of the embedded waterstop 63 is pre-installed in the instrument pier body 5, and the other end is pre-installed in the building structure body 7. The embedded waterstop 63 divides the seismic isolation groove into two areas, preventing the water below the embedded waterstop 63 from penetrating into the upper part of the embedded waterstop 63 in the seismic isolation groove, avoiding water leakage and ensuring the safety of the measuring instruments on the instrument pier. The polystyrene board 61 is arranged in the seismic isolation groove 4 and on the upper and lower sides of the embedded waterstop 63 to protect the embedded waterstop 63 and prevent water leakage due to damage to the embedded waterstop 63, thus forming the second waterproof measure. The external pasted waterstop 65 is fixed at one end in the joint surface between the bottom of the instrument pier and the bedrock, and the other end is fixed in the joint surface between the building body structure and the bedrock. The left side of the external pasted waterstop 65 is protected by a waterstop rubber, and the right side is protected by a waterproof coiled material 67 and fixed by a foam plastic rod 66 to form the third waterproof measure to prevent the bedrock fissure water from penetrating into the seismic isolation groove.
[0028] The embedded waterstop 63 is located in the middle and lower part of the seismic isolation groove 4. The fine sand in the upper part of the seismic isolation groove is isolated by a polyurethane sealant 62, and the embedded waterstop 63 is installed on the upper and lower sides of the polystyrene board 61 to protect the embedded waterstop 63. One end of the embedded waterstop 63 is pre-installed in the instrument pier body 5, and the other end is pre-installed in the building structure body 7, and a whole is formed by cast-in-place concrete to play a waterproof role.
[0029] The external pasted waterstop 65 extends out of the joint surface between the bottom of the instrument pier 5 and the bedrock 8 after being folded and then continues to extend reversely along the pasted position of the external pasted waterstop to the joint surface between the building body structure 7 and the bedrock 8.
[0030] The waterproof coiled material 67 is bonded to the top and side surfaces of the bedrock 8. One end of the foam plastic rod 66 is fixed on the surface of the waterproof coiled material 67, and the other end fixes the external pasted waterstop 65 to prevent the external pasted waterstop 65 from falling off and form an effective waterproof measure.
[0031] The technical effects of the present utility model are mainly reflected in that: three waterproof systems are formed through the cooperation among the drainage ditch, the embedded waterstop and the external pasted waterstop. Among them, the external pasted waterstop blocks the bedrock fissure water from entering the seismic isolation groove, the embedded waterstop prevents the seepage water entering the seismic isolation groove from continuing to overflow above the seismic isolation groove, and the drainage ditch is the last waterproof system to prevent the instrument pier platform from being flooded and damaged. At the same time, the polystyrene board protects the embedded waterstop, and the waterproof coiled material and the foam plastic rod protect the external pasted waterstop, playing a long-term waterproof effect, reducing the operation cost and ensuring the accuracy of instrument comparison and observation.
[0032] Of course, the above are only typical examples of the present utility model. In addition, there can be many other forms of the present utility model. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present utility model.
