Abstract
The utility model relates to a quick connecting head of a wall-protective sleeve in the pile-hole construction of static-pressure pouring piles, comprising two tensioning rings which are respectively fixed at the butted pipe ends of two sections of the wall-protective sleeve and at least two clamping hoops which embraces the tensioning rings. A sheathing relationship is formed by the two sections of the protective sleeve, and a labyrinth seal is formed at the butted position, and the cross sections of the clamping hoops are I-shaped. The butted position of the adjacent clamping hoops is provided with a clamping ear, and a connecting hole used for passing through a fastener is arranged on the clamping ear. The quick connecting head can realize the quick connection and separation of the wall-protective sleeve, the outer force of pressing pipe and drawing pipe can be borne and transferred, and the sealing performance is good.
Description
The utility model relates to the snap joint of the protection casing in a kind of static pressure hole for grout pile construction.
Protection casing is to be pressed into soil layer and to pursue joint welding lengthening by joint in the construction of static pressure hole for grout pile, in the process of from soil layer, extracting, unload by the joint cutting again, each welding and cutting all will delay for a long time, this not only influences speed of application, and along with the prolongation soil layer of the time pressure to tube wall can recover to strengthen gradually, and cause the increase of pressure pipe and tube drawing resistance.
The purpose of this utility model is to connect fast and the snap joint that separates fast for the protection casing in the construction of static pressure hole for grout pile provides a kind of can the realization.
The snap joint of the protection casing in the construction of this static pressure hole for grout pile has butt joint pipe ends that two circles are separately fixed at the protection casing of two joint butt joints to be made two joint protection casings form nested relationship and forms the cranse of labyrinth seal and Contraband at least two boards hold around cranse and section is the bail of type at joint, the joint of adjacent bail is provided with the clamping ear, clamps and then is provided with the connecting hole that passes for securing member on the ear.
When in the construction of static pressure hole for grout pile, adopting the protection casing snap joint of said structure, the aligning of two joint protection casings is fast, the bail assembly unit is fast and dismounting is also fast, therefore can reach quick connection and the purpose of separating fast, in addition, the external force of pressure pipe and tube drawing can be born and transmit to this snap joint, and good seal performance, so functional performance is also fine.
Illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: structure chart of the present utility model;
The vertical view of Fig. 2: Fig. 1.
As shown in the figure, the snap joint of the protection casing in the construction of described static pressure hole for grout pile has butt joint pipe ends that two circles are separately fixed at the protection casing 1,2 of two joint butt joints to be made two joint protection casings 1,2 form nested relationship and forms the cranse 4,5 of labyrinth seal 3 and at least two boards hold around cranse 4,5 and section is the bail 6 of Contraband type at joint, the joint of adjacent bail 6 is provided with and clamps ear 7, clamps and then is provided with the connecting hole 8 that passes for securing member on the ear 7.Present embodiment is designed to three boards with bail 6, and the radian that holds around of every board bail 6 is 120 °, on clamping ear 7 upper and lower two connecting holes 8 is set, and cranse 4,5 is welded on the protection casing 1,2, and securing member generally adopts screw bolt and nut.
