Abstract

The utility model discloses a kind of dewatering well and extend protective device; be applied to concrete structure engineering construction; described protective device comprises extending and fixed bar; described extending is tubular structure; the barrel of described extending is provided with multiple water inlet; the lower surface of described extending is fixedly connected with multiple fixed bar; described fixed bar inserts on base plate; the external diameter of described extending is more than or equal to the internal diameter of described dewatering well, and described extending is fixed on the top of described dewatering well by described fixed bar and the cylinder chamber of described extending is connected with the well chamber of described dewatering well.The utility model, by arranging extending structure, ensure that carrying out smoothly of work of drawing water, improves operating efficiency under heavy rain weather or the more situation of foundation ditch; Meanwhile, because extending height is higher, be convenient to observation, improve the safety of user of service's operation; In a word, the utility model meets the user demand of user, is convenient to industrially promote.

Description

Dewatering well extends protective device
Technical field
The utility model belongs to concrete structure engineering construction tool technical field, particularly relates to a kind of dewatering well and extends protective device.
Background technology
In building field, often use dewatering well, dewatering well is the well beaten for dewatering, puts into water pump groundwater abstraction after having beaten, and reduces the water level of underground water.
In work progress; if run into heavy rain weather; especially south China region, much rain in summer even heavy rain, often can flood foundation ditch; comprise dewatering well; thus the work of drawing water cannot be carried out, meanwhile, due to the position of dewatering well cannot be observed; if constructor enters in foundation ditch, the danger of dewatering well also may be fallen into.
Summary of the invention
The purpose of this utility model be to provide a kind of dewatering well extend protective device, to solve in work progress, if run into heavy rain weather or foundation ditch internal water accumulation more time, the problem that constructor falls into the danger of dewatering well be carried out and be occurred to the work of drawing water cannot.
In order to realize the purpose of this utility model, the utility model provides a kind of dewatering well and extends protective device, be applied to concrete structure engineering construction, described protective device comprises extending and fixed bar, described extending is tubular structure, the barrel of described extending is provided with multiple water inlet, the lower surface of described extending is fixedly connected with multiple fixed bar, described fixed bar inserts on base plate, the external diameter of described extending is more than or equal to the internal diameter of described dewatering well, described extending is fixed on the top of described dewatering well by described fixed bar and the cylinder chamber of described extending is connected with the well chamber of described dewatering well.
Further, described fixed bar is Metallic rod.
Further, described dewatering well is arranged in foundation ditch, and described extending at least possesses the height of position higher than the upper surface of described foundation ditch of a water inlet.
The utility model, compared with prior art, by arranging extending structure, ensure that carrying out smoothly of work of drawing water, improves operating efficiency under heavy rain weather or the more situation of foundation ditch; Meanwhile, because extending height is higher, be convenient to observation, improve the safety of user of service's operation; In a word, the utility model meets the user demand of user, is convenient to industrially promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-water inlet, 2-extending, 3-fixed bar, 4-base plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of dewatering well and extends protective device, be applied to concrete structure engineering construction, described protective device comprises extending and fixed bar, described extending is tubular structure, the barrel of described extending is provided with multiple water inlet, the lower surface of described extending is fixedly connected with multiple fixed bar, described fixed bar inserts on base plate, the external diameter of described extending is more than or equal to the internal diameter of described dewatering well, described extending is fixed on the top of described dewatering well by described fixed bar and the cylinder chamber of described extending is connected with the well chamber of described dewatering well.
Above-mentioned dewatering well is arranged in foundation ditch.
When using, be fixed on by fixed bar on the base plate of foundation ditch, the top end opening of extending is pump mouth, and water enters in dewatering well by the water inlet on barrel, utilizes pumping equipment to enter from pump mouth, can draw water;
The utility model, compared with prior art, by arranging extending structure, ensure that carrying out smoothly of work of drawing water, improves operating efficiency under heavy rain weather or the more situation of foundation ditch; Meanwhile, because extending height is higher, be convenient to observation, improve the safety of user of service's operation; In a word, the utility model meets the user demand of user, is convenient to industrially promote.
Further, described fixed bar is Metallic rod.
In order to ensure to draw water the validity of work and handling safety work further, the height of position higher than the upper surface of described foundation ditch that extending at least possesses a water inlet is set.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
