Patent CN217630139U discloses a sleeve tool for acoustic pipe connection length, which is only suitable for acoustic pipe connection, or has the problems of unsatisfied impermeability, and also has no condition for convenient distributed grouting, and thus, the sleeve tool cannot be used for one pipe for multiple purposes.
The invention comprises the following steps:
The utility model aims to solve the problems that in the distributed grouting process of the bridge pile foundation, construction operators are difficult to operate, the joint of a grouting pipeline leaks, the pipeline in a reinforcement cage is simplified, one-pipe multi-purpose is realized, construction is simplified, and a one-pipe multi-purpose bridge pile foundation sounding pipe structure for guaranteeing the high strength and the tightness of the joint is provided.
The technical scheme adopted for solving the technical problems is as follows:
a multi-purpose bridge pile foundation sound survey tubular construction of pipe, including two sound survey pipes, sleeve, slip casting head, sleeve both ends link to each other with two sound survey pipes respectively, its characterized in that: the middle part of the sleeve is provided with a threaded hole, one end of the grouting head is provided with threads and matched with the threaded hole of the sleeve, and the grouting head is fixed in the threaded hole of the sleeve through threads.
The distance Hmm between the inner diameter of the sleeve and the outer diameter of the sounding pipe is more than 0 and less than or equal to 1.
The sleeve and the sound tube are steel tubes, the sound tube is fully welded by adopting a chromium-nickel stainless steel welding rod after being inserted into the sleeve, the end part is beveled, and the bevel angle is 60-70 degrees. The welding rod adopts a chromium-nickel stainless steel welding rod, and has corrosion resistance and mechanical properties. Because the welding is full welding, no notch exists, and leakage is prevented.
The wall thickness of the sounding pipe is required to be larger than that of a steel pipe with the thickness of 2mm, so that the phenomenon of slurry leakage caused by too thin steel pipe and easy slurry leakage is avoided.
The length of the sleeve is three times of the outer diameter of the grouting head end, one third of the two ends of the sleeve are used for being connected with two sounding pipes, and the middle one third of the sleeve is provided with a threaded hole which is connected with the grouting head through threads.
The utility model has simple structural processing procedure, connects the acoustic measuring pipes at two ends through the sleeve welding, and connects the grouting head through the sleeve threaded hole, thereby realizing 'one pipe with multiple purposes', also ensuring that the joint has good high strength and water seepage prevention effect, and having simple and convenient construction operation for workers, and better solving the quality problem in actual construction.
Description of the drawings:
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic view of a grouting head according to the present utility model.
Fig. 3 is a schematic view of a sleeve according to the present utility model.
The specific embodiment is as follows:
the utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1-3, the multi-purpose bridge pile foundation sounding pipe structure of the utility model comprises two sounding pipes (1, 5), a sleeve 3 and a grouting head 6, wherein two ends of the sleeve 3 are respectively connected with the two sounding pipes (1, 5), and the multi-purpose bridge pile foundation sounding pipe structure is characterized in that: the middle part of the sleeve 3 is provided with a threaded hole, one end of the grouting head 6 is provided with threads and matched with the threaded hole of the sleeve 3, and the grouting head 6 is fixed in the threaded hole of the sleeve 3 through threads.
As shown in fig. 1, the following is a specific embodiment of the present utility model:
The two acoustic pipes (1, 5) are steel pipes with the outer diameter of 57mm and the wall thickness of 3.0 mm; the sleeve 3 is made of a steel pipe with the outer diameter of 82mm, the wall thickness of 12mm and the length of 120mm, a 40mm grouting threaded hole is formed in the middle of the sleeve of the steel pipe, and threads with the distance of 2mm are reserved in the wall thickness of the threaded hole; the grouting head 6 is a grouting head with threads with a spacing of 2mm at one end.
Firstly, inserting one end of a first sound tube 5 into a sleeve 3, wherein the insertion distance is 40mm which is one third of the length of the sleeve, and no gap exists basically after insertion;
Welding the joint of the first acoustic tube 5 and the sleeve 3 by adopting a chromium-nickel stainless steel welding rod; during welding, the first welding line 4 is full, the end parts are beveled, and the bevel angle is 60-70 degrees.
Step three, repeating the step one and the step two to perform sleeve welding on one end of the second acoustic tube 1, inserting the second acoustic tube 1 into the non-welded part of the other end of the sleeve 3, wherein the insertion distance is 40mm of the length of the sleeve, and no gap exists basically after insertion; the joint of the second acoustic tube 1 and the sleeve 3 is welded by adopting a chromium-nickel stainless steel welding rod; during welding, the second welding line 2 is full, the end parts are beveled, and the bevel angle is 60-70 degrees.
Step four: one end of a grouting head 6 with threads is screwed on the threaded hole of the sleeve 3, so that no gap is ensured.
When the utility model is used, in the process of lowering the pile foundation reinforcement cage to connect the sounding pipes, one end of each of the two connected sounding pipes is only required to be put into the sleeve with the sleeve sounding pipe, and then the joint is welded tightly by using an electric welding machine. Because the wall thickness of the sleeve is 12mm, the difference between the inner diameter of the sleeve and the outer diameter of the sounding pipe is 1mm, so that the high strength of the sleeve is ensured, and the small gap between the sleeve and the sounding pipe is ensured. The grouting head is screwed on the sleeve of the sound measuring tube, so that the follow-up distributed grouting is convenient. The welding is full welding, and no notch exists, so that leakage is prevented.
