Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a method for manufacturing a protection sleeve for a pile foundation acoustic detection tube. Background Art

[0002] In order to detect the quality of a concrete pile foundation, a pile foundation acoustic detection tube is pre-embedded in the concrete pile foundation, and an acoustic detection instrument extends into the pile foundation through the pile foundation acoustic detection tube for detection. In order to protect the pile foundation acoustic detection tube and prevent objects from falling in, the existing method is to knead a flexible object into a ball and block it inside the upper end of the pile foundation acoustic detection tube, and there is a lack of a special protection device for protection. The method of blocking with a kneaded flexible object is prone to the phenomenon that it is accidentally inserted too deep and difficult to take out, and the protection effect is poor; for this reason, those skilled in the art conduct research on the protection technology of the pile foundation acoustic detection tube. Summary of the Invention

[0003] The present invention aims to provide a method for manufacturing a protection sleeve for a pile foundation acoustic detection tube that can reliably protect the pile foundation acoustic detection tube, and also solves the problem that the pile foundation acoustic detection tube lacks a special protection device for protection.

[0004] To achieve the above object, the present invention adopts the following technology: A method for manufacturing a protection sleeve for a pile foundation sonic logging tube, characterized in that it is completed through a mold. The mold includes a core mold and an outer mold with an upper opening sleeved at the lower end of the core mold. A cavity for forming the protection sleeve of the pile foundation sonic logging tube is enclosed between the core mold and the outer mold. The protection sleeve of the pile foundation sonic logging tube includes a sleeve for sleeving on the upper end of the pile foundation sonic logging tube to seal the pile foundation sonic logging tube. The sleeve includes a tube body and a top wall closed at the upper end of the tube body. The lower end of the tube body is open to form an insertion opening. The sleeve is an elastic structure capable of elastic expansion and contraction. The insertion opening is connected with a rigid holding ring. A plurality of swing rods are arranged in the tube wall of the tube body along the circumferential direction of the tube body and extending axially. A rigid ring is arranged inside one end of the side wall of the tube body connected to the top wall. One end of the swing rod is rotatably sleeved on the rigid ring. The other end of the swing rod is provided with a pressing spring for driving the swing rod to move towards the inside of the tube body to press the tube body against the pile foundation sonic logging tube and a swing rod relaxation structure arranged on the rigid holding ring for driving the swing rod to move away from the inside of the tube body. A hanging step is formed between the rigid holding ring and the tube body. The outer mold is provided with an outer mold part hanging block for supporting on the hanging step. The core mold is provided with a core mold part hanging block for hanging on one end of the rigid holding ring away from the tube body. The process of manufacturing the protection sleeve for the pile foundation sonic logging tube is as follows: Keep the outer mold in a state where the open end is upward. Connect the swing rod assembled with the rigid ring and the rigid holding ring together according to requirements. Input the swing rod into the outer mold and hang it on the outer mold part hanging block through the hanging step. Insert the core mold into the outer mold until the core mold part hanging block hangs on one end of the rigid holding ring away from the tube body. A cavity for forming the protection sleeve of the pile foundation sonic logging tube is enclosed between the core mold and the outer mold, and the swing rod passes through the cavity. Pour the molten material for manufacturing the sleeve from the upper end of the cavity into the cavity and solidify it to form the sleeve. When protecting the pile foundation sonic logging tube, sleeve the sleeve on the upper end of the pile foundation sonic logging tube with the insertion opening facing downward to seal the pile foundation sonic logging tube to prevent objects from falling into the pile foundation sonic logging tube. When the tube sleeve needs to be removed or put on, loosen the pressing action of the swing rod on the sleeve through the swing rod relaxation structure, and then hold the rigid holding ring to put the sleeve on or remove it from the pile foundation sonic logging tube. When the sleeve is sleeved on the pile foundation sonic logging tube, the sleeve is tightened on the pile foundation sonic logging tube under the action of the pressing spring. The manufactured sleeve can not only be tightened on the pile foundation sonic logging tube but also be easily removed.

[0005] Preferably, the entire circumference of the insertion opening is sealed and cast together with the rigid holding ring. This can avoid generating gaps between the rigid holding ring and the sleeve and interfering with the sleeving of the sleeve on the pile foundation sonic logging tube.

[0006] Preferably, the open end of the outer mold is provided with an outward-turned edge, which forms the hanging block of the outer mold part. The peripheral edge of the outward-turned edge is provided with an upward-turned edge. During use, the outer peripheral surface of the rigid holding ring abuts against the inner peripheral surface of the upward-turned edge for positioning; the hanging block of the core mold part uses a downward-turned edge. During use, the outer peripheral surface of the rigid holding ring abuts against the inner peripheral surface of the downward-turned edge for positioning. Positioning can be carried out, facilitating the position of the swing rod in the casing and the casing to meet the requirements.

[0007] Preferably, when the casing is sleeved on the pile foundation acoustic detection tube, the end of the swing rod connected to the rigid ring is in a state of being pressed against the casing. This can improve the tightening effect of the casing.

[0008] Preferably, the rigid ring is aligned with the top wall. This enables the swing rod to swing significantly.

[0009] Preferably, two retaining rings are provided on the rigid ring and are distributed on both sides of the swing rod. This can prevent the molten casing material from entering the rotating surfaces of the swing rod and the rigid ring during pouring, thereby affecting the swing of the swing rod.

[0010] Preferably, an annular sealing groove is provided on the swing rod, and a sealing flange is provided on the outer edge of the retaining ring and is inserted into the annular sealing groove. The sealing flange is annular with the axis of the swing of the swing rod as the center line. This enables the swing rod to still swing easily even though the casing is formed by pouring.

[0011] Preferably, a clearance is provided between the retaining ring and the swing rod. This enables the swing rod to swing more labor-savingly.

[0012] Preferably, the rigid holding ring is provided with accommodation pits distributed along the circumferential direction of the casing. The accommodation pits are located on the upper end surface of the rigid holding ring. The swing rods are correspondingly inserted into the accommodation pits one by one. The swing rod relaxation structure includes a seesaw rod hinged in the accommodation pit through a hinge shaft and a pressing pin inserted through the outer side wall of the accommodation pit and abutting against one end of the seesaw rod. One end of the pressing spring presses against the other end of the seesaw rod, and the other end is connected to the inner surface of the outer side wall of the accommodation pit. The swing rod overlaps on the side of the seesaw rod facing the outer side wall of the accommodation pit. During use, hold all the pressing pins, the pressing pins retract and drive the seesaw rod to swing and overcome the elastic force of the pressing spring, thereby driving the swing rod to swing in the loosening direction. When the pressing action on the pressing pins is lost, the seesaw rod resets under the action of the pressing spring, and the swing rod resets.

[0013] Preferably, an elastic holding ring is further sleeved on the rigid holding ring, and the outer ends of the pressing pins are connected to the inner peripheral surface of the elastic holding ring. When using, holding the elastic holding ring to drive the pressing pins can improve the reliability of driving all the pressing pins simultaneously and improve the comfort during use.

[0014] Beneficial effects: It can reliably protect the sonic logging tubes of pile foundations, prevent the phenomenon of falling into the sonic logging tubes of pile foundations, and can be recognized at night. Brief Description of the Drawings
