Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device for correcting the inclination of a buried pipe, which is a tubular member to be buried, in the excavation work of a vertical shaft such as a well, which is a method of burying a buried pipe, which is a tubular member such as a fume pipe and a caisson, while excavating underground. It is about.

[0002]

[Prior art]

 Conventionally, this kind of buried pipe straightening has been performed by tapping the highest part of the annular member being buried from above or by putting a heavy object on it, which is extremely dangerous and therefore the applicant of the present application. First disclosed the utility model application publication No. 35916 in 1990.

The above-disclosed application is to lay an iron plate or the like covering an excavation site of a vertical shaft such as a well or the like and fix the jacks in four directions. Further, four steel members having a length are square-shaped inside. The frame was assembled so that the jacks were fixed to the respective steel materials, and the inclination of the buried pipe was adjusted by advancing and retracting the rod of the jack.

[0004]

[Problem to be solved]

 However, the planned site of the shaft to be excavated is not only a place where iron plates can be laid, but also a narrow place, and there is also a place where there is no space to assemble even four steel materials into a square.

[0005]

[Means for solving the problem]

 The buried pipe tilting device of the present invention was devised as a result of intensive research focusing on the above reasons.Therefore, a pair of rail-shaped guides were radially provided at least in three directions near the planned excavation site of a vertical shaft such as a well. Each of them is fixed, and the roller fixing base with a pair of guide frames is slidably mounted on the pair of guides. To the rear end, the jacks with which the front and rear rods are brought into contact are fixed to the rear, respectively.

[0006]

[Function of the invention]

 The function of the present invention is to provide jacks at least in three directions and radially in the vicinity of the planned excavation site of a vertical shaft such as a well.Therefore, by advancing / retreating the rod of one or more jacks, the buried pipe being buried is buried. The inclination can be corrected.

[0007]

[The purpose of the device]

 An object of the present invention is to provide an inclination correcting device for a buried pipe that can be easily installed even in a narrow excavation site such as a well.

[0008]

【Example】

 The present invention which achieves such an object will be described below with reference to the drawings of the embodiments.

FIG. 1 is a plan view for explaining an embodiment of the present invention, and FIG. 2 is an overall explanatory view of the embodiment of the present invention.

The present invention is a buried pipe A which is a tubular member to be buried in the excavation work of a vertical shaft such as a well in a method of burying a buried pipe A which is a tubular member such as a fume pipe and a caisson while excavating underground. The present invention relates to a device for correcting the inclination of a rail, which fixes a pair of rail-shaped guides 1 in at least three directions and radially in the vicinity of a planned excavation site of a vertical shaft such as a well, and a pair of guides 1 is respectively fixed to the pair of guides 1. The roller fixing bases 2 having the guide frames 2a are slidably mounted respectively, and the rollers 3 which rotate in the vertical direction are provided at the tips of the respective roller fixing bases 2 and the respective roller fixing bases are provided. To the rear end of the jack 2, the jacks 4 to which the front ends of the advancing and retracting rods 4a abut are fixed to the rear.

That is, when excavating a vertical shaft using the inclination correcting device for the buried pipe A of the present invention, the inside and below of the buried Hume pipe, the buried pipe A which is a tubular member such as a caisson, and the like are excavated to remove soil and the like. It is used for the method of constructing a vertical shaft by discharging it and causing it to sink due to the dead weight of the buried pipe A.

First, the guides 1 are fixed in at least three directions and radially in the vicinity of the planned site for excavating a vertical shaft such as a sewer, a vertical shaft for maintenance of a common groove, and a well for securing industrial water. The guide 1 is a rail-shaped one, which is a pair of two guides, and is fixed in three directions and radially from the center position of the shaft to be excavated in the embodiment shown in FIG.

The fixing means of the guide 1 is provided with a fixing hole in a horizontal portion of the guide 1 and a pile or the like is driven into the fixing hole to fix the fixing hole. It may be fixed by placing a log or the like between them, and may be fixed so as not to move backward.

The guides 1 fixed in at least three directions do not have to be evenly spaced, so if the guides 1 are arranged over more than half of the outer circumference of the buried pipe A to be buried, the buried pipe A described below will be inclined. The adjustment can be made at any time, and the number is not particularly limited to four directions or five directions as long as it is at least three directions or more.

The roller fixing base 2 slidably mounted on each pair of guides 1 is provided with a pair of guide frames 2a fitted to the rail-shaped guides 1 on both sides. It freely slides on the guide 1 toward a vertical shaft for excavation.

Next, a roller 3 that rotates in the vertical direction is provided at the tip of each roller fixing base 2, and the roller 3 damages or breaks the buried hume pipe, the buried pipe A such as a caisson, or the like. It is made of an elastic member such as rubber or synthetic resin so that it does not move, and the rotation shaft is provided in the horizontal direction, and the roller 3 is provided so as to be rotatable upward and downward.

Next, the advancing / retreating rods 4a of the jacks 4 projecting forward and backward are brought into contact with the rear ends of the respective roller fixing bases 2, and the jacks 4 are fixed behind the roller fixing bases 2. It is what

The buried pipe A, which is the tubular member to be buried, is mainly a concrete pipe such as a fume pipe or a caisson. First, the buried pipe A at the tip is placed on the planned excavation site of the vertical shaft, and the buried pipe A The ground surface inside A is excavated by an earth drill machine or an excavator such as an excavation bucket to discharge the earth and sand. When the excavation proceeds, the ground below the tip of the buried pipe A is also excavated and sinks due to its own weight. When the buried pipe A at the tip is buried, the next buried pipe A is placed on the buried pipe A and the two are joined to continue the excavation work, and the buried pipe A is inclined in the process during the excavation. The jack 4 of the inclination straightening device is operated to straighten it vertically to construct a vertical shaft having a certain depth.

[0019]

[Effect of device]

 The inclination correcting device for buried pipe according to the present invention, which has the above-described structure, can be installed even in a place where a vertical shaft to be excavated is narrow, which is safe and practical. Is.
